1 General description

MULTICAL® 803 is a robust and all-round calculator, suitable as heat meter, cooling meter or bifunctional heat/cooling meter together with 1 or 2 flow sensors and 1, 2, 3 or 4 temperature sensors. The calculator is intended for energy measurement in almost all types of thermal installations where water is used as the energy-conveying medium.
MULTICAL® 803 can, in addition to heat and cooling energy measurement in both open and closed systems, be used for leakage monitoring, permanent performance monitoring, power, flow and temperature limiter with valve control.
According to EN 1434 and MID, MULTICAL® 803 can be designated as a “calculator” with separate type approval and verification. The MULTICAL® 803 calculator top can be separated from the connection base by means of a screw driver HEX 4 (4 mm Allen key) when the installation seals have been broken. This provides free access to the installation of flow sensor, temperature sensors, backup battery and communication modules. The calculator top is sealed from factory. The calculator can only be disassembled on approved meter laboratories. If the factory seal is broken, the factory guarantee no longer applies.
MULTICAL® 803 has 2 flow sensor inputs that can be used for both electronic and mechanical flow sensors. The pulse value can be configured from 0.001 to 300 pulses/liter and the calculator can be configured for all nominal flow sensor sizes from 0.6 to 15,000 m inputs that fit ULTRAFLOW® and, for example, reed switches. In addition, a connection board with 2 galvanically isolated flow sensor inputs can also be supplied.
3
/h. By default, the calculator is supplied with galvanically coupled flow sensor
MULTICAL® 803 has automatic conversion between Pt100 and Pt500 sensors. The calculator even detects the type of the connected temperature sensor. However, all connected sensors must be of the same type. Accurately matched Pt500 or Pt100 sensors measure the temperatures in inlet and outlet pipes according to EN 60 751 and EN 1434. MULTICAL® 803 has 4 temperature sensor inputs that all have 4-wire connection allowing up to 100 m sensor cable. Sensor inputs can, however, also be used with 2-wire connection, either by shortening the outer terminals in each 4­wire connection or by inserting a common 2x8 jumper above the connection terminals 3-7-8-4.
The accumulated heat energy and/or cooling energy can be displayed in kWh, MWh, GJ or Gcal with 7 or 8 significant digits plus measuring unit. The display has been specially designed with a view to obtaining long lifetime and sharp contrast in a wide temperature range and, by default, MULTICAL® 803 has backlit display.
Other reading options are: accumulated water consumption, operating hour counter, error hour counter, current temperature measurements, current flow and power readings. Furthermore, MULTICAL® 803 can be configured to display monthly and yearly loggings, target date data, max/min. flow, max/min. power, information code, current date as well as user-defined tariffing.
MULTICAL® 803 can be mains-supplied either by 24 VAC or 230 VAC. A built-in battery backup also ensures that the calculator continues the energy measurement for up to 6 years in case of a voltage failure. The backlight of the display is always off during
backup, but the display can be read in illuminated rooms. Furthermore, it is possible to
connect a battery backup to module slot M1 by which, for example, M-Bus or wM-Bus will continue to operate during a voltage failure.
In addition to the energy meter’s own data, MULTICAL® 803 can display the accumulated consumptions of four extra water meters, e.g. cold and hot water meters, which supply a pulse signal to MULTICAL® 803 via reed switch or electronic output. The contact signals from the extra water meters are connected via the communication modules M1 and M2.
On the back of the top cover, several multi connectors are located, which to some extent create the link between calculator, connection base and communication modules. In addition, these multi connectors enable calibration and adjustment. MULTICAL® 803 is available with up to 4 communication modules for Wireless M-Bus, M-Bus, RS232 and many more. Most of the modules are available with either pulse inputs or pulse outputs for use in the module slots M1 and M2.

In designing MULTICAL® 803, great importance has been attached to flexibility through programmable functions and plug-in modules (see paragraph 11) to secure optimum use in a wide range of applications. In addition, the construction makes it possible to update previously installed MULTICAL® 803 via the PC-program METERTOOL HCW.
This technical description has been written with a view to enabling operations managers, meter installers, consulting engineers and distributors to utilize all functions comprised in MULTICAL® 803. Furthermore, the description is targeted at laboratories performing tests and verification.

3.2 Module combinations

MULTICAL® 803 supports up to four communication modules. It is possible to deliver many combinations of the calculator's four communication modules. MULTICAL® 803 can thus be mounted with four communication modules in such combinations that support the majority of installation and communication requirements.
Below is a guide for guidelines for the combinations of communication modules. Pay particular attention to these guidelines when ordering the communication modules separately.
1.
Only one wireless communication module
2.
Only one PQT or analog input module
3.
Internal antenna only on module slot 1 (M1)
4.
Battery backup on module slot 1 (M1) can be selected for, for example, wM-Bus and M-Bus.
5.
Only on module slots 1 and 2 (M1 and M2)
6.
On the module slots M1 and M2, only one 8x communication module is allowed to be installed on one of the module slots, e.g. the 2G/4G network module. The same applies to the module slots M3 and M4

3.4.1 Flow sensor position >A<

Code A indicates installation of flow sensor in inlet or outlet. As the density and heat capacity of water vary with temperature, the calculator must correct this based on the installation position (A code). Incorrect programming or installation leads to error of measuring. See paragraph 4.3 for further details on the installation of the flow sensor in inlet and outlet as far as heat and cooling installations are concerned.

3.4.2 Measuring unit >B<

The B code indicates the measuring unit used in the energy register. The options are GJ, kWh, MWh or Gcal.

In the following five paragraphs, the CCC codes are described:
3.4.3.1 ULTRAFLOW® X4
Auto Detect ULTRAFLOW® (UF) enables the exchange of ULTRAFLOW® X4 on MULTICAL® 803 without the need for changing the CCC code. MULTICAL® 803 can automatically adjust its CCC code to match the connected ULTRAFLOW® X4 via the function Auto Detect UF. Auto Detect UF is active with the CCC code 8xx.
Auto Detect UF works in such a way that MULTICAL® 803, during start-up, automatically collects the correct information about meter factor and qp from the connected ULTRAFLOW® X4 flow sensors. MULTICAL® 803 adapts its configuration to the values that are received from ULTRAFLOW® X4. Auto Detect UF is initiated when the calculator top and base are separated and reassembled. Read more about the connection of ULTRAFLOW® and Auto Detect UF in paragraph 8.1.
MULTICAL® 803 can be supplied with Auto Detect UF if this comes with CCC code 8xx, but can also be supplied with a static CCC code 4xx (7 digits) or 5xx (8 digits). After delivery, it is possible to change the CCC code and select Auto Detect UF or disable it.

3.4.4 Display code >DDD<

MULTICAL® 803 has 4 display loops: USER, TECH, SETUP and TEST. The TECH loop contains all display views, except for logged values and the differential registers (ΔE and ΔV), and this loop is not configurable. The USER loop, however, is configurable and can be adapted to customer requirements by means of the DDD code (display code). As a minimum, the USER loop always comprises the calculator’s legal readings.
The calculator’s legal readings, e.g. energy and volume readings, are basically displayed as 7-digit or 8-digit values. The number of digits and resolution of the calculator's legal registers are configured with the CCC code, see paragraph 3.4.3. The first digits of the three-digit DDD code define the meter type comprised by the DDD code in question. The table shows examples of a number of DDD codes within each meter type. In the table, “1” indicates the first primary reading, whereas e.g. “1A” is the first secondary reading. The display automatically returns to reading “1” after 4 minutes.

3.4.5 Tariffs >EE<

MULTICAL® 803 has three extra registers TA2, TA3 and TA4, which can accumulate heat energy or cooling energy (EE=20 accumulates volume) parallel to the main register based on preprogrammed tariff conditions (to be stated in the order of the calculator). Irrespective of the selected tariff type, the tariff registers are named TA2 TA3 and TA4 in the display.
As the main register is considered the legal billing register, it is accumulated no matter the selected tariff function. Tariff conditions TL2, TL3 and TL4 are monitored at every integration. If the tariff conditions are fulfilled, consumed heat energy is accumulated in either TA2, TA3 or TA parallel to the main register.
Example of power tariff (EE=11)
Three tariff conditions, TL2, TL3 and TL4, which are always used in the same tariff type, are connected to each tariff function. Therefore, it is not possible to “mix” two tariff types, except from the PQ tariff (EE=21).
TA2 shows energy consumed…
meter uses TA2 and TA3 only, and the tariff function works as in the previous model, MULTICAL® 801.
TA4 is deactivated by setting the tariff limit TL4 to 0.

The inlet temperature tariff can be used as a basis for billing consumers who are guaranteed a certain inlet temperature. If the “guaranteed” minimum temperature is entered in TL4, the payable consumption is accumulated in TA4.
EE=15 Outlet temperature tariff
If the current outlet temperature (t2) exceeds TL2, but is lower than or equal to TL3, energy is counted in TA2 parallel to the main register. If the current outlet temperature exceeds TL3, but is lower than or equal to TL4, energy is counted in TA3 parallel to the main register.

The time-controlled tariff is used for time division of heat consumption. If TL2 = 08:00, TL3 = 16:00 and TL4=23:00, the daily consumption from 08:00 until 15:59 is accumulated in TA2, whereas the consumption during the evening from 16:00 until 22:59 is accumulated in TA3 and the consumption during the night from 23:00 until 07:59 is accumulated in TA4.
TL2 must include fewer hours than TL3 and TL3 must include fewer hours than TL4.

The time-controlled tariff is suitable for billing in housing areas close to industrial areas with large district heating consumption as well as for billing industrial customers.
EE=20 Heat/cooling volume tariff
The heat/cooling volume tariff is used to divide volume into heat and cooling consumption in combined heat/cooling meters, i.e. the tariff divides the consumed volume into heat and cooling volume for combined heat/cooling meters. The total volume is accumulated in the register V1, whereas TA2 accumulates the volume consumed together with E1 (heat energy) and TA3 accumulates the volume consumed together with E3 (cooling energy).

3.4.6 Tariff limits with Auto Detect UF of ULTRAFLOW® X4

Auto Detect UF enables the exchange of ULTRAFLOW® X4 on MULTICAL® 803 without the need for changing the CCC code. MULTICAL® 803 can automatically adjust its CCC code to match the connected ULTRAFLOW® X4 via the function Auto Detect UF. Auto Detect UF is active with the CCC code 8xx. Read more about it in paragraph 8.1.1.
The resolution of the tariff limits is adapted to the nominal flow qp and is thus controlled by the selected CCC code. The tariff limits do not change value by Auto Detect UF, but the value resolution and device can change. An example with a flow-controlled tariff is shown below.

Note:

3.4.7 Pulse inputs A and B >FF-GG<

Up to four communication modules can be mounted in MULTICAL® 803. Pulse inputs are supported on communication modules placed in slot M1 and slot M2. See paragraph 11 for further information about the communication modules.
The pulse inputs are used for collection and remote accumulation of pulses from e.g. mechanical water meters and electricity meters. The pulse inputs function independently of the calculator itself. Therefore, they are not included in any energy calculation. The four pulse inputs are identically constructed and can be set up to receive pulses from water or electricity meters.
Pulse inputs A and B are placed on selected communication modules. If the module is installed in slot M1 in MULTICAL® 803, the inputs A1 and B1 are identified, and the same applies to slot M2; with inputs A2 and B2.
The pulse inputs A1 and A2 will always be identically configured through the FF code and
likewise, the pulse inputs B1 and B2 will always be identically configured through the GG code.
Therefore, pay special attention to this when the modules are installed in the meter so that

The table below is a part of the type number overview, which shows the module type numbers. The table distinguishes between modules with pulse inputs (In-A, In-B) and modules with pulse outputs (Out-C, Out-D).
MULTICAL 803 registers the accumulated consumption of the meters connected to the inputs and saves the counter values every month and every year on target date. The number of these yearly and monthly loggings depends on the selected logger profile (RR code). Read more about data logger profiles in paragraph 3.4.12. In order to facilitate the identification during data reading, it is also possible to save the meter numbers of the four meters connected to the inputs. The meter numbers can be either programmed in the meter via the SETUP loop (for A1 and B1) or via METERTOOL HCW (for A1, B1, A2 and B2).
Which pulse input registers are collected through the module is controlled by the selected
datagram profile of the module, which is configured through the module's ZZZ code.
Two alarm types are connected to the pulse inputs: cold water leakage and external alarm, respectively. Unless otherwise informed by the customer, the calculator is, in general, prepared for external alarm on all four inputs from the factory, but only with one active leakage alarm on inputs A1 and A2. Please contact Kamstrup A/S if you need leakage alarm possibility on input B1 and B2. Read more about cold water leakage in paragraph 3.4.10 and info codes in paragraph 7.8.

The registers which are connected to the pulse inputs can be read in the calculator’s TECH loop, in USER loop (depending on selected DDD code) and via data communication. Furthermore, it is possible to pre-set the meter count of the four pulse inputs to the values that the connected meters have at the time of the commissioning. This can be done either via the calculator’s SETUP loop (for A1 and B1) or via METERTOOL HCW (for A1, B1, A2 and B2).

3.4.8 Integration mode >L<

MULTICAL® 803 uses time-based integration, which means that accumulated volume and energy are calculated at fixed time intervals and independently of the water velocity.
MULTICAL® 803 can only be mains-supplied. The calculator has a backup battery, but in normal operation, the calculator is mains-supplied. Therefore, the calculator display will always be switched on and the integration interval will always be 2 seconds. Only the backlight of the display is configured via the L code.
It is possible to choose between two integration modes; one mode in which the backlight of the display remains on and one mode in which the backlight of the display turns off after 15 seconds after the latest registered keystroke. Via the “heart beat” indication in the bottom left corner of the display, the calculator display will at all times show that the calculator is active.
Fast mode (2 s) 15 s. 4 -
Fast mode (2 s) On 9 -
Note: When MULTICAL® 803 is powered by the backup battery, the calculator automatically adjusts the integration interval to 8 seconds to conserve power.
Fast mode (2 s) In fast mode, the integration interval is set to 2 seconds, which means that the calculator calculates accumulated
volume and energy every 2 seconds.
Fast mode (2 s) is recommended for all systems including those with tap water exchanger. Fast mode (2 s) is particularly suitable for applications where the calculator is provided with analog outputs.
Integration concept The integration concept of MULTICAL® 803 is illustrated in the figure below.

3.4.9 Leakage limits (V1, V2) >M<

MULTICAL® 803 can be used for leakage monitoring when two flow sensors are connected to MULTICAL® 803 on inputs V1 and V2.
The M code defines the leakage limit, i.e. the leakage monitoring sensibility. If a leakage is detected in the system, the info code for leakage or burst is activated, depending on the size of the leakage. The leakage search is based on a
difference in mass (ΔMass) between the calculated mass for V1 and V2, respectively. The calculation of this
difference in mass is carried out over 24 hours why the reaction time of the info code for leakage is 24 hours. The burst search is based on a difference in flow for V1 and V2, respectively. The burst search is performed over a period of 120 seconds. Read more about these info codes in the info code overview in paragraph 7.8.
The sensibility of a leakage can be adjusted via the M code while the sensibility of a burst is fixed. This also appears from the table of the M code below. It is possible to detect leakages down to 15 kg/h with the connection of two flow sensors of qp 1.5 m³/h. Both the info code for leakage and for burst can be disabled via the M code (M = 0).

Permanent operational monitoring
Leakage monitoring can with advantage be extended to include permanent performance monitoring as it just requires the installation of a set of three sensors instead of a sensor pair. In Denmark, for example, permanent performance monitoring reduces the number of random samples to three meters per random sampling lot, no matter the size of the measuring lot. Read more in the permanent performance monitoring guide (5512-1486_GB). The purpose of this guide is to provide caretakers, installers and consulting engineers with the information needed on Kamstrup's leak monitoring system and permanent performance monitoring.

3.4.10 Cold water leakage (In-A/In-B) >N<

The pulse inputs A and B of MULTICAL® 803 can be used for cold water leakage monitoring. Basically, however, the cold water leakage monitoring is only active on input A (A1/A2), unless otherwise agreed with the customer. When MULTICAL® 803 is used for leak monitoring, the sensitivity is determined by the configuration of the N code.
Leakage monitoring is measured over a period of 24 hours. The N code defines the resolution by which the 24 hours are divided; either 48 intervals of half an hour, 24 intervals of one hour or 12 intervals of two hours. If the calculator registers minimum one pulse during each of these intervals over the full period, info code 8, which indicates leakage, is activated. The info code is not activated until after the 24-hour period. However, it is reset again immediately as soon as the calculator registers an interval without pulses.
The table below shows the three available N codes. Upon receipt of order, the N code is configured to 2 by default (unless otherwise informed by the customer).

3.4.11 Pulse outputs C and D >PP<

Up to four communication modules can be mounted in MULTICAL® 803. Pulse outputs are supported by communication modules placed in slot M1 and slot M2. See paragraph 11 for further information about the communication modules.
MULTICAL® 803 can have up to four pulse outputs (C1, C2, D1 and D2), which are placed on the communication modules. The pulse outputs have three possibilities of use:
- Transmission of selected meter count registers (which are controlled by the selected country code).
- Controlled output, which means that the pulse outputs can be controlled via data commands.
- Pulse Transmitter/Divider so that the pulse signal from V1 and V2 is transmitted via the pulse outputs.
Pulse outputs C and D are placed on selected communication modules. If the module is installed in slot M1 of MULTICAL® 803, the outputs C1 and D1 are identified, and the same applies to slot M2; with the outputs C2 and D2.

The pulse outputs are configured as part of the calculator’s configuration number via the PP code. Upon receipt of order, the PP code is configured to 95 by default (unless otherwise informed by the customer). Valid PP codes appear from the table below. The default code 95 is marked in green. The PP code can be reconfigured by means of METERTOOL HCW. See the technical description of METERTOOL HCW (5512-2097).
3.4.11.1 Pulse Transmitter/Divider
The calculator can be configured so that the pulse outputs serve as either Pulse Transmitter or Pulse Divider. If the outputs must serve as Pulse Transmitter, the calculator’s PP code is configured to either 80 or 82. Regardless of whether both outputs are connected or floating, the PP code 80 with Pulse Transmitter on both Out-C and Out-D causes an increased power consumption. If the outputs must serve as Pulse Divider, the calculator's PP code is configured to 83 with 22 ms pulse duration or PP code 73 with 5 ms pulse duration.
Pulse Transmitter/Divider can, among other things, be used for external leak protection and makes it possible to connect an additional calculator to the same flow sensor and to external control systems that regulate according to flow pulses, for example Siemens RVD 250 and Danfoss ECL 310, both of which can use the PP code 73 with 5 ms pulse duration.
3.4.11.2 Pulse outputs for meter count registers
As previously described, the outputs are configured in pairs (C1/C2 and D1/D2), which means that it is possible to transmit output from two of the following meter count registers on pulse output C1/C2 and pulse output D1/D2, respectively:
• E1 (Heat energy)
• E3 (Cooling energy)
• V1 (Volume)

Note: As the selected meter count registers are configured by the country code, the configuration cannot be changed after delivery.
Pulse outputs are by default configured with the following registers:

Heat/cooling meter E1 (CE+) E3 (CE-) 3, 6
Cooling meter E3 (CE-) V1 (CV) 5
Volume meter V1 (CV) V1 (CV) 7
The resolutions of the pulse outputs always follow the least significant digit in the display, which is determined by the CCC code (see paragraph 3.3.3), e.g. at CCC=119: 1 pulse/kWh and 1 pulse/0.01 m
Note that the pulses are accumulated in the integration interval and transmitted by each integration with a fixed frequency. This is shown in the example below.

3.4.11.3 Controlled output
The calculator can be configured for data command control of pulse outputs. If controlled output is required, the PP code is to be configured to 99. As previously described, the outputs are configured in pairs (C1/C2 and D1/D2), which means that externally connected equipment can set the calculator's outputs, in the pairs C1/C2 and D1/D2, to respectively OFF (open opto transistor output) and ON (closed opto transistor output) via KMP data commands.
The output status can be read via the KMP registers and after a power-on reset, the outputs will have the same status as before the power failure as every change of status is saved in the calculator’s EEPROM.

3.4.12 Data logger profile >RR<

MULTICAL 803 has a permanent memory (EEPROM) in which the results from various data loggers are saved. The data logger is programmable. The required data logger profile is selected via the RR code of the configuration number. Unless otherwise stated by the customer, the RR code is set to 10, which is the default data logger profile (equal to the data logger in MULTICAL® 603). If data logging of other registers, different intervals and logging depths are required, other data logging profiles can be composed to match individual requirements.
The programmable data logger includes the following six data loggers:
- Yearly logger
- Monthly logger
- Daily logger
- Hourly logger
- Minute logger 1
- Minute logger 2

When the datagram of the modules are configured via the module's ZZZ code, it is important that the
necessary registers that you want to transmit via the datagram also exist in the meter. Therefore,
there must be consistency between the choice of the meter's RR code and the module’s ZZZ code.

IMPORTANT: If the encryption key in the meter is changed after the meter is supplied, and the encryption type

3.4.13 Encryption level >T<

MULTICAL® 803 must be ordered with encrypted data transmission between module and reading system. Data is encrypted with 128 bit AES counter mode encryption. Data transmission can be encrypted with either a common or an individual encryption key.
If you select individual encryption key (T code 3), the reading system must know the encryption key of the individual calculator in order to read the meter. The encryption key is sent to the customer and then ”matched” with the serial number of the individual meter in the reading system.
If you select common encryption key (T code 2), the key can be used for reading a customer-specific number of meters. The key is created by Kamstrup A/S. A customer can have several encryption keys, e.g. one for each meter type.
Note: The common encryption key is only offered to customers on request.
The encryption level is configured as part of the calculator’s configuration number via the T code. Upon receipt of order, the T code is by default configured at 3 - individual encryption key (unless otherwise informed by the customer). The encryption level can be configured when submitting the order. The encryption level cannot be changed after delivery.
Encryption keys can be downloaded from Kamstrup’s customer portal “My Kamstrup” at www.kamstrup.com
.
Encryption keys are automatically entered in USB Meter Reader and READy.
is thus changed from individual to common key or vice versa, the T code is not changed. The T code shown in
the meter’s display always indicates with which encryption type the meter was ordered and not the current
encryption type of the meter.

3.4.14 Customer label >VVVV<

A 20x50 mm customer label can be engraved on the calculator’s front. The customer label to be engraved on the calculator’s front is determined by the calculator's configuration number VVVV code. The customer label can show utility logo, a bar code or the like. By default, the calculator’s serial number is engraved in the customer label field.
Please contact Kamstrup A/S for information about possible customer labels as well as the creation of a new customer label.

3.5.2 Target date

MULTICAL® 803 can be configured with up to two yearly target dates and two monthly target dates. These dates determine on which date data is to be logged (saved) in the calculator’s interval logger. To avoid confusion about which time of the day the calculator saves data, MULTICAL® 803 also, in addition to the date, includes a time stamp for the logging. This time stamp is not included in this calculator’s predecessor, MULTICAL® 801, which simply stamps data with a date. This difference also means that the date stamps of the two calculators vary in spite of the fact that both calculators are configured with a target date, e.g. 01.01 [MM.DD]. Note that although the date stamps of the two calculators are different, both calculators will in practice log (save) data at the same time. This is illustrated by the following example:
[MM.DD]
[DD]
[20YY.MM.DD/ hh.mm.ss]
1
Note that it is not possible to read out this time stamp from the calculator.
[MM.DD] [hh.mm.ss]
12.31 24.00.XX
[MM.DD] [hh.mm.ss]
01.01 00.00.XX
When using MULTICAL® 803 together with systems that are dependent on data being logged with a given target date, it is important to select this date as target date in the calculator’s configuration. The target date can be configured both via the calculator’s front keys in the SETUP loop and via METERTOOL HCW, see paragraph 6.4 and the technical description of METERTOOL HCW (5512-2097), respectively. If the target date is required to be set to the last day of the month, the monthly target date [DD] is set to 31. MULTICAL® 803 automatically logs on the last day of months with less than 31 days.

4 Installation

4.1 Installation requirements

Prior to installation of MULTICAL® 803 in connection with flow sensors, the heating system should be flushed while a fitting piece replaces the flow sensor. When installing an ULTRAFLOW®, the adhesive wafers are removed from the flow sensor’s inlet and outlet and the flow sensor is mounted with couplings/flanges. New fibre gaskets in original quality must be used.
If other couplings than the original ones from Kamstrup A/S are used, you must make sure that the threaded lengths of the couplings do not prevent proper tightening of the sealing surface.
The calculator is configured for mounting of flow sensor in inlet or outlet before commissioning, see paragraph 6.4 about the SETUP loop. The flow direction is indicated by an arrow on the flow sensor.
To avoid cavitation, the back pressure at ULTRAFLOW® (the pressure at the flow sensor outlet) must typically be minimum 1 bar at qp and minimum 2 bar at qs. This applies to temperatures up to approx. 80
When the installation has been completed, water flow can be turned on. The valve on the flow sensor's inlet side must be opened first.
ULTRAFLOW® must not be exposed to lower pressure than the ambient pressure (i. e. a vacuum).
Permissible operating conditions
Ambient temperature: 5…55°C (indoors). Max 30 °C for optimum battery lifetime on backup.
Medium temperature of heat meter: 2…130 °C with calculator mounted on a wall
15…90 °C with calculator mounted on ULTRAFLOW®
Medium temperature of cooling meter: 2…130 °C with calculator mounted on a wall
Medium temperature of heat/cooling meter: 2…130 °C with calculator mounted on a wall
Installation pressure ULTRAFLOW®: 1.0…16 bar for threaded meters
1.5…25 bar for flange meters
Electrical installations MULTICAL® 803 is available with either 24 VAC/VDC or 230 VAC supply. Mains connection of MULTICAL® 803 is made
with a two-wire cable without protective earth. Use a strong connection cable with an outer diameter of 4-10 mm and ensure correct cable stripping and cable relief in the calculator. It must be ensured that the whole installation complies with the applicable rules. The supply cable to the calculator must never be protected by a fuse larger than permitted. In cases of doubt, it is recommended to seek advice from an authorised electrician.
o
C.
For installation in Denmark, SIK-message 27/09, “Installation to mains connected equipment for registration of consumption” applies to calculators connected to both 230 VAC and 24 VAC powered via safety transformer, see paragraph 10.9.
Service Neither welding nor freezing is allowed whilst ULTRAFLOW® is mounted. Before initiating the work, ULTRAFLOW®
must be dismounted and the mains supply must be disconnected.
To facilitate the replacement of the meter, stop valves should always be mounted on both sides of the flow sensor.
Under normal operating conditions, no pipe strainer is required in front of the meter.

It is recommended to mount the calculator directly

4.2 Mounting of MULTICAL® 803 calculator

4.2.1 Wall-mounting

on an even wall. Wall-mounting requires the use of three screws with corresponding rawlplugs. It is recommended to use 6 mm rawlplugs and 4...4.5 mm screws. MULTICAL® 803 is mounted on the wall by first mounting the upper screw in the wall and screwing this almost all the way in. Then, the calculator is hung on this screw. With the calculator mounted on the upper screw, the positions of the lower two screw eyes are marked on the wall after which screws for these can be mounted.

4.2.2 Compact mounting

In some cases, compact mounting of the MULTICAL 803 calculator may be an advantage. The
MULTICAL for compact mounting in places where the installation can be secured against mechanical influences such as draught and impacts. By compact mounting, the calculator is mounted directly on ULTRAFLOW® using mounting bracket 3026-857. If there is risk of condensation (e.g. in cooling applications), the calculator ought to always be wall­mounted. Furthermore, ULTRAFLOW® in cooling applications must be the condensation-proof version.

4.4 Connection of temperature sensors and flow sensors

MULTICAL® 803 always has the same number of connection terminals on the connection board. The connection terminals are placed in a row at the bottom of the calculator base and all connection terminals are numbered. When ordering MULTICAL® 803 prepared for flow sensors with 24 V active/passive pulses (type P), an additional connection board will, in addition to the connection terminals on the connection board, be mounted across the connection terminals of the flow sensor connection for galvanic separation between 24 V pulses and calculator. It is always possible to rebuild and reconfigure MULTICAL® 803 to flow sensors with 24 V active/passive pulses (type P) using this extra connection board (6699-045) and METERTOOL HCW. An overview of the possible connections are shown in the figure below. This figure is also available on the grey verification cover in the calculator top of MULTICAL® 803.

Figure 3: For the use of 2-wire sensor pair, install supplied short-circuit jumper marked in red. For the use of internal
24 VDC supply marked in orange, MULTICAL® 803 must be delivered with supply type A or C. Additional connection
boards for flow sensors with 24 V active/passive pulses (type P) are shown in the upper right corner (6699-045).

4.5 Commissioning

Carry out an operational check when the energy meter has been fully mounted. Open thermoregulators and valves to enable water flow through the heating system. Use the front keys on MULTICAL® 803 to change the display view and check that credible display values for temperatures and water flow are shown. Read more about the MULTICAL® 803 display content in paragraph 3.4.4.
Using meters with Auto Detect Pt and/or Auto Detect UF Note that MULTICAL® 803 has a built-in engagement delay of up to 20 seconds to ensure that all plug connections between calculator top and base are established before a detection of Pt-sensors and/or ULTRAFLOW® X4 is initiated.

4.6 EMC conditions

MULTICAL® 803 has been designed and CE-marked according to EN 1434 Class A and C (corresponding to electromagnetic environment: Class E1 and E2 of the Measuring Instruments Directive) and can thus be installed in both domestic, light industry and industrial environments.
All control cables must be drawn separately and not parallel to e.g. power cables or other cables with the risk of inducing electromagnetic interference. There must be a distance of min. 25 cm between signal cables and other installations.
Kamstrup A/S · Technical description · 5512-2360_A1_GB_02.2019
65

4.7 Climatic conditions

MULTICAL® 803 is designed for indoor installation in condensing environments with ambient temperatures from 5…55 °C, but max 30 °C in order to obtain optimal battery lifetime. Protection class IP65 of the calculator allows splashes of water.

4.8 Sealing

According to EN 1434, MULTICAL® 803 must have protection devices, which can be sealed to the effect that after sealing, both before and after the heat calculator has been correctly installed, it is impossible to dismount, remove or change the calculator or its adjustment devices without visibly damaging the calculator or sealing. Correct sealing of MULTICAL® 803 includes two levels, installation sealing and verification sealing. A breach of sealing has different consequences on each level.
Installation sealing Having completed the installation of MULTICAL® 803, installation sealing is the last thing to be done. The installation
seal is the ‘outermost’ sealing level to be completed by the installer/utility. The installation sealing must make sure that calculator top and base cannot be separated and that flow sensor and temperature sensors cannot be dismounted without visible signs that a separation has taken place. In practice, the installation sealing can be done by means of wire and seal, sealing label or a combination. The sealing is the utility’s security that unauthorized persons cannot undiscovered change the installation around the calculator. A breach of the installation sealing alone does not influence the calculator’s possibility for renewed installation sealing or the fact that it is legal in relation to its approval and verification.
Installation sealing and SETUP loop In order to bring MULTICAL® 803 back to SETUP loop after installation, the calculator top and base must be
separated after which SETUP loop can be accessed either via front keys or via METERTOOL HCW. Separation of calculator top and base implies that the calculator’s installation seal is broken.
Verification seal The MULTICAL® 803 verification seals consist of both mechanical and electronic sealing. Verification seals, marked
with “TEST” and three seal marks (void labels) marked with “Red Kamstrup”, are placed on the grey verification cover in the calculator top. These seals can be seen as the ‘innermost’ sealing level, which may only be broken by authorized laboratories in connection with test and reverification of the calculator. If the calculator is to be used for legal operation in relation to approval and verification after breach of the verification sealing, the broken seals must be resealed. The sealing must be carried out by an authorized laboratory using the sealing mark (void label) of the laboratory.

4.9 Replacement and installation of supply modules

Supply modules should only be replaced by qualified persons. For the replacement and installation, exclusively original spare parts must be used. Prior to any replacement of supply modules, MULTICAL® 803 must be placed in a deenergized state.
It is possible to replace or add supply modules to MULTICAL® 803 after delivery. The connection board is dedicated to either 24 VAC/VDC or 230 VAC. Therefore, it is only possible to replace or add supply modules to the same voltage range as the supply module(s), which MULTICAL® 803 is delivered with, unless the connection board is also replaced.
The supply modules are placed at the bottom of the calculator base on a bracket underneath the connection board and the bracket for communication modules. A step-by-step guide for replacing/adding supply modules to MULTICAL® 803 can be found on the next page.

MULTICAL® 803 has a bright and clear display including 7 or 8 digits depending on the configuration as well as a number of symbols for measuring units, info, inlet and outlet, radio on/off, etc. The display changes view or turns on by pressing one of the buttons on the calculator front. MULTICAL® 803 also has illumination in the display that can be configured to be permanently on or to automatically turn off 15 seconds after the last keystroke, depending on the selected integration mode (L code). Read more about the calculator’s integration modes in paragraph 3.4.8.

The calculator uses four different display loops. The four loops are intended for four different usage situations.
• USER loop
The calculator’s configurable display loop which is intended for the user. The readings in this loop can be adjusted to the utility company’s requirements via the DDD code. See paragraph 3.4.4 for an overview of possible readings in the calculator’s USER loop. The same paragraph includes examples of DDD codes.
• TECH loop
This loop is intended for technicians and is not configurable. The TECH loop contains all display readings, except for logged values and the differential registers (∆E and ∆V). The loop comprises readings such as serial number, date, time, configuration number, software revision and segment test. See paragraph 6.2 for a complete overview of the readings.
• SETUP loop
The SETUP loop is intended for the technician too. In this loop, the technician can configure the calculator via the front keys. In general (unless otherwise informed by the customer), the loop is open in transport state. First time the calculator detects a flow of 1 % of qp or greater, the access to the SETUP loop is blocked. From now on, it is no longer possible to access the SETUP loop unless you break the installation seal. See paragraph 6.4 for further details about the various parameters that can be configured in the SETUP loop and see paragraph 7.9 for details about the calculator’s transport state.
• TEST loop
This loop is used by authorized laboratories for reverification of the calculator. This loop is not available unless the calculator’s test seal (verification seal) is broken.

Kamstrup A/S · Technical description · 5512-2360_A1_GB_02.2019
Display of differential temperature
By means of the calculator’s primary keys, you can choose from and switch between the four display loops. When delivered, the calculator is in transport state, which means that the USER, TECH and SETUP loops are available. Depending on country code, the access to the SETUP loop can be blocked in transport state and is thus not available on delivery. The TEST loop can only be accessed if the test seal (verification seal) is broken.
By keeping the primary key activated for 5 seconds, the Select loop appears. Here, it is possible to use the arrow keys to switch between the calculator’s display loops. In the TECH, SETUP and TEST loops, use index numbers as the views in these display loops are allocated to a specific index number. The index numbers facilitate navigation to the required reading. Index numbers are not used in the configurable USER loop. The figure below illustrates how it is
possible to navigate in the calculator’s display by means of the front keys.
Readings in case of error
In order to facilitate the diagnostics work, lines are shown in the display readings (current values) which are influenced by the error and at the same time, counting stops in the registers, which are dependent on the given parameter and thus influenced by the error. In case of an interrupted or short-circuited temperature sensor, the corresponding display reading shows lines and energy calculations, which are dependent on the faulty measurement, will stop. MULTICAL® 803 registers these errors and sets an info code, which can easily be read from the display. Read more about the info codes in paragraph 7.8.

Display reading in case of blocking of flow After a blocking of the installation, the flow display in MULTICAL® 803 will drop to 0 l/h within a few seconds when a flow sensor with quick pulses such as ULTRAFLOW® is used. When MULTICAL® 803 is connected to flow sensors with slow pulses, e.g. reed switch, the flow display first shows a decreasing flow several minutes after a blocking. MULTICAL® 803 automatically sets the flow display to 0 l/h after 60 minutes without pulses. For flow sensors with slow pulses, the flow display generally responds slower and is less suitable for displaying low flows than when using flow sensors with quick pulses.

6.1 USER loop

USER loop is the calculator’s primary loop, which includes legal and mostly used readings. The loop is intended for the user and is configured according to the user’s requirements via the DDD code. See paragraph 3.3.4 for further information about the USER loop and DDD codes.
Note: No display index numbers are used in the USER loop.

6.2 TECH loop

The TECH loop is intended for the technician who is interested in viewing more readings than the ones available in the USER loop.
The TECH loop contains all display readings, except for logged values and the differential registers (∆E and ∆V), and this loop is not configurable. The module readings consist of a number of fixed readings as well as a number of readings that depend on the installed modules.
The calculator’s TECH loop is shown below. You change back and forth between the readings by means of the arrow keys while pressing the primary key briefly causes the change between the primary and secondary readings.

6.3 Module readings

The TECH loop includes a number of module readings which depend on the mounted modules. These readings are described in the respective technical descriptions of the modules. Simple modules, however, only include the primary reading “Type/Config. no.” (for module on slot 1: index number 2-101-00). If the calculator is not equipped with a module, “Type/Config. no.” is displayed as “00000000”.
Note: Module readings can be empty due to delay or interrupted communication between calculator and module. The heart beat indication shows that both calculator and display are active. See the beginning of this chapter for more information about the heart beat and status indications.

IMPORTANT:

6.4 SETUP loop

In this loop, the technician can configure the calculator via the front keys. This enables the technician to configure the calculator both before installation and after the commissioning of the calculator. Configuration of the calculator after commissioning requires that the installation seal is broken, and that the calculator top and base are subsequently separated and reassembled.
After 50 times, the meter is locked against further configuration and total reset and reverification of the
How to enter the SETUP loop?
1. In general (unless otherwise informed by the customer), the SETUP loop is available when the calculator is in
transport state. The calculator leaves the transport state the first time it detects a flow of 1 % of qp or greater or if the SETUP loop is exited through the menu item “EndSetup”. A total reset of the calculator is the only way to return to transport state.
2. When the calculator is in operation, i.e. the calculator has left transport state, the SETUP loop can be accessed
by breaking the calculator’s installation seal and separating and reassembling the calculator top and the calculator base.
How to exit the SETUP loop?
You can exit the SETUP loop in three ways. All three ways can be used both in transport state and after commissioning of the calculator.
1. Keep the primary key activated and navigate to one of the calculator’s other loops.
2. After 4 minutes, the calculator reaches timeout and reverts to the first reading in the USER loop.
3. Navigate to the menu item “EndSetup” in the SETUP loop and keep the primary key activated for 5 seconds while
the frames around the reading counts up and the display in the end shows “OK”. Note: This locks the access to the SETUP loop and thereby, the calculator is locked against further configuration. If the calculator is to be reconfigured subsequently, the installation seal must be broken and the calculator top and base must then be separated and reassembled.
“EndSetup” is an important function when the meter is in transport state, but when the meter
is in operation, “EndSetup” is just one of three ways to exit the SETUP loop.
As it appears from the table below, the purpose of the menu item “EndSetup” is to enable the technician to lock the access to the SETUP loop in transport state and thus lock the calculator against further configuration. This function is, for example, relevant to a technician who knows that a calculator is to be mounted in the installation for some time before the first integration will be carried out and wants to lock the access to the SETUP loop immediately after the installation to make sure that no further configuration is possible.

6.4.1 Change of parameters in SETUP loop

The technician can navigate to the SETUP loop from the USER loop by keeping the primary key activated for 5 seconds and then use the arrow keys to navigate to 3-SETUP, which can be accessed with a single touch of the primary key. The SETUP loop does not include secondary readings and therefore, the index number always consists of 4 digits. See the table with SETUP parameters on the next page. The arrow keys are used to switch between readings.
In the SETUP loop, the primary key is used to access individual readings with the purpose of changing the parameter in question. Pressing the primary key, the first digit of the parameter in question (the digit farthest to the left) starts flashing. The flashing digit can now be changed through brief activations of the primary key. Switch between the digits by pressing the arrow keys. You can freely switch to both right and left. When the desired setup is entered, keep the primary key activated until “OK” appears on the display. The calculator has now saved the change and the display shows the set values.
Depending on the calculator’s configuration, one or more menu items in the SETUP loop are displayed as “OFF”. This means that the function is not available in the calculator, i.e. the function has been disabled during factory programming. If you try to access these readings via the primary key, the frames around “OFF” are shown to indicate that the function is not available in the calculator.

1. and 2. Customer number The customer number is a 16-digit number distributed on two 8-digit menu items. The complete customer number
can be adjusted via the two menu items in the SETUP loop.
3. Date The calculator’s date can be adjusted in the SETUP loop. We recommend you to verify that the date was adjusted
correctly, especially if time was adjusted too.
4. Time The calculator’s time can be adjusted in the SETUP loop. We recommend you to verify that the time was adjusted
correctly, especially if the date was adjusted too.
5. Yearly target date 1 The calculator’s yearly target date 1 can be adjusted in the SETUP loop. In MULTICAL® 803, yearly target date 2 can
be activated. This function is switched off by default, i.e. set to 00.00. If yearly target date 2 is active in a calculator, we recommend that both yearly target dates are adjusted via METERTOOL HCW to ensure that they are correctly set with respect to each other. Note that activation of yearly target date 2 influences the depth of the yearly log as the calculator now makes two yearly loggings.
6. Monthly target date 1 The calculator’s monthly target date 1 can be adjusted in the SETUP loop. In MULTICAL® 803, monthly target date 2
can be activated. This function is switched off by default, i.e. set to 00. If monthly target date 2 is active in a calculator, we recommend that both monthly target dates are adjusted via METERTOOL HCW to ensure that they are correctly set with respect to each other. Note that activation of monthly target date 2 influences the depth of the monthly log as the calculator now makes two monthly loggings.

87
7. Flow sensor position: Inlet or outlet flow (A code) The installation position of the flow sensor can be adjusted in the SETUP loop. This means that the calculator can be
changed from being an outlet meter to being an inlet meter and vice versa. A symbol in the top left corner of the calculator’s display shows whether the calculator is configured as an inlet or outlet meter.
8. Energy unit (B code)
The calculator’s measuring unit (B code) and resolution (CCC code) can be adjusted in the SETUP loop. It is thus possible to change if the calculator’s energy readings should be displayed in kWh MWh, GJ or Gcal.
Note: The resolution of the energy unit will always follow the one specified for the CCC code that a given MULTICAL® 803 is configured with. See the CCC tables in paragraph calculator with a CCC code where kWh is not possible, MULTICAL® 803 automatically switches to MWh.

9. Primary address of module slot 1
The primary address of module slot 1 in MULTICAL® 803 can be adjusted in the SETUP loop. The address can be selected in the interval 0…250.
10. Primary address of module slot 2 The primary address of module slot 2 in MULTICAL® 803 can be adjusted in the SETUP loop. The address can be selected in the interval 0…250.
11. Primary address of module slot 3 The primary address of module slot 3 in MULTICAL® 803 can be adjusted in the SETUP loop. The address can be selected in the interval 0…250.

13. Averaging period of min./max P and Q
The averaging period used in the calculation of minimum and maximum values of power (P) and flow (Q) can be adjusted. The averaging period is entered in the range 1…1440 minutes. Read more about the averaging period of min./max of P and Q in paragraph 7.5.
14. Heat/cooling shift (θhc)
The limit (θhc) for heat/cooling shift can be adjusted in the SETUP loop, however only in calculators ordered as meter type 6 (heat/cooling meter). The value can be selected in the range 2…180.00 °C as well as at 250.00 °C if the user wants to disable the function. The function is enabled again by setting the limit at a value in the valid area of 2…180 °C. Heat/cooling shift is permanently disabled in other meter types and therefore, “OFF” is displayed in all other meter types than 6. Read more about heat/cooling shift in paragraph 7.4.

89
Be aware of setting the required offset adjustment, not the error of the temperature sensor pair.
IMPORTANT:
15. Temperature sensor offset (tr0)
Temperature sensor offset (tr0) can be adjusted in the SETUP loop. Depending on the calculator’s configuration, this function can be disabled and the menu item will in that case display “OFF”.
Offset can be adjusted in the interval -0.99…0.99 K. Pressing the primary key, the 0 and the sign start flashing and it is now possible to switch between – and +, indicated in the display by the fact that the minus sign flashes and switches of respectively. Use the arrow keys to shift to the digits to the right of the decimal point, i.e. it is not possible to change the value of the first digit as the valid interval is -0.99…0.99 K. Both the first and the second decimal can be set to a value between 0 and 9. Read more about temperature sensor offset in paragraph 7.3.
If the selected temperature sensor pair contributes with an error of -0.20 K, the meter’s offset must be set
to 0.20 K.
Note: The set offset is active for all temperature sensors connected to MULTICAL® 803, i.e. both t1, t2, t3 and t4.
16. Radio on/off The calculator’s radio/wireless communication can be adjusted to being switched on or switched off. The calculator
automatically turns on the radio when the calculator leaves the transport state, i.e. when the calculator has detected a flow of 1 % of qp or greater. The radio on/off function in the SETUP loop is primarily used for switching on the radio in transport state without the calculator having registered a flow as well as for switching off the radio when the calculator is dismounted after having been in operation, e.g. if it is to be sent by airfreight. The calculator’s present condition is indicated by two symbols in the bottom left corner of the display.
- If the meter’s radio communication is switched off via the SETUP loop, the calculator subsequently switches on radio communication again the first time it registers a flow of 1 % of qp or greater.
- The symbols for radio on/off indicate whether the meter allows radio communication, not
whether a radio module has activated its radio communication. Be aware of this when troubleshooting the meter’s wireless communication.
The above definition of the radio on/off symbols simplify the use of radio on/off in the SETUP loop too as it is possible to switch between radio on and radio off regardless of whether a module is mounted in the calculator or not. This offers flexibility that enables a utility company to configure the calculator prior to mounting a module and thus to make sure that radio is either by default switched on in transport state or switched off when the module is subsequently mounted.

has been selected during configuration of the calculator, i.e. the EE code differs from “00”. The EE code is shown in the TECH loop, see paragraph 6.2. If a tariff type has been selected, the menu items reflect this by displaying the correct tariff limit units. If no tariff type has been selected, the menu items will be without units. Read more about tariff types in paragraph 3.4.5.

24. Preset t5 The temperature value t5 can be adjusted in the interval 0.01...185.00 °C in the SETUP loop. This value is used in
connection with the calculation of outlet energy registers, i.e. registers A1 (A-, heat at a discount) and A2 (A+, heat with an addition). Read more about this calculation and function in paragraph 7.1.3.
25. EndSetup The menu item “EndSetup” enables the technician to lock the access to the SETUP loop in transport state and thus
lock the calculator against further configuration. In order to do so, the user must keep the primary key activated for five seconds. During the five seconds, the frames around the reading EndSetup will be shown in the calculator’s display. This action can be undone by releasing the primary key before the whole frame has been shown, i.e. before the five seconds have passed.
“EndSetup” is an important function when the calculator is in transport state.If the calculator is in operation, “EndSetup” is just one of three ways to exit the SETUP loop. See paragraph 6.4.

6.5 TEST loop

The TEST loop is, for example, used by authorized laboratories for reverification of the calculator, among other things.
Before the calculator can enter the TEST loop and thus the TEST mode, the verification seal marked “TEST” on the calculator’s verification cover must be carefully broken with a screwdriver and the contact points behind the seal be short-circuited. For this purpose, a short-circuit pen (6699-278) from Kamstrup A/S can be used.
It is recommended to complete the work in the TEST loop before starting a reconfiguration via the SETUP loop or METERTOOL HCW as every reconfiguration is logged in MULTICAL® 803 (it is only possible to reconfigure MULTICAL® 803 50 times).
The calculator either leaves the TEST loop and returns to the first reading in the USER loop after 9 hours (timeout) or if the user keeps the primary key activated for 5 seconds and manually leaves the TEST loop via the Select loop.
