2. GENERAL SAFETY PRECAUTIONS

All activities described in this manual shall be carried out by an installer.

Be sure to wear adequate personal protection equipment (protection gloves, safety glasses, …) when performing installation, maintenance or service to the unit.

If not sure of installation procedures or operation of the unit, always contact your local dealer for advice and information.

Improper installation or attachment of equipment or accessories could result in electric shock, short-circuit, leaks, ﬁre or other damage to the equipment. Be sure only to use accessories and optional equipment made by Daikin which are specially designed for use with the products as of subject in this manual and have them installed by an installer.

DANGER: ELECTRICAL SHOCK

Switch off all power supply before removing the switch box service panel or before making any connections or touching electrical parts.

Do not touch any switch with wet ﬁngers. Touching a switch with wet ﬁngers can cause electrical shock. Before touching electrical parts, turn off all applicable power supply.

To avoid electric shock, be sure to disconnect the power supply 1 minute or more before servicing the electrical parts. Even after 1 minute, always measure the voltage at the terminals of main circuit capacitors or electrical parts and, before touching, be sure that those voltages are 50 V DC or less.

When service panels are removed, live parts can easily be touched by accident. Never leave the unit unattended during installation or servicing when the service panel is removed.

DANGER: DO NOT TOUCH PIPING AND INTERNAL PA RT S

Do not touch the refrigerant piping, water piping or internal parts during and immediately after operation. The piping and internal parts may be hot or cold depending on the working condition of the unit.

Your hand may suffer burns or frostbite if you touch the piping or internal parts. To avoid injury, give the piping and internal parts time to return to normal temperature or, if you must touch them, be sure to wear protective gloves.

WARNING

■ Tear apart and throw away plastic packaging bags so that children will not play with them. Children playing with plastic bags face danger of death by suffocation.

■ Safely dispose of packing materials. Packing materials, such as nails and other metal or wooden parts, may cause stabs or other injuries.

■ Ask your dealer or qualiﬁed personnel to carry out installation work. Do not install the machine by yourself. Improper installation may result in water leakage, electric shocks or ﬁre.

■ Perform installation work in accordance with this installation manual. Improper installation may lead to water leakage, electric shocks or ﬁre.

■ Be sure to use only the speciﬁed accessories and parts for installation work. Failure to use the speciﬁed parts may result in water leakage, electric shocks, ﬁre, or the unit falling.

■ Install the unit on a foundation that can withstand its weight.

■ Insufﬁcient strength may result in the fall of equipment and causing injury.

■ Carry out the speciﬁed installation work in consideration of strong winds, hurricanes, or earthquakes. Improper installation work may result in accidents due to fall of equipment.

■ Make certain that all electrical work is carried out by qualiﬁed personnel according to the applicable legislation and this installation manual, using a separate circuit. Insufﬁcient capacity of the power supply circuit or improper electrical construction may lead to electric shocks or ﬁre.

■ Be sure to install an earth leakage circuit breaker in accordance with the applicable legislation. Failure to do so may cause electrical shock and ﬁre.

■ Make sure that all wiring is secure, using the speciﬁed wires and ensuring that external forces do not act on the terminal connections or wires. Incomplete connection or ﬁxing may cause a ﬁre.

■ When wiring between the indoor and the outdoor units and wiring the power supply, form the wires so that the panels can be securely fastened. If the panels are not in place, overheat of the terminals, electric shocks or a ﬁre may be caused.

■ After completing the installation work, check to make sure that there is no leakage of refrigerant gas.

■ Never directly touch any accidental leaking refrigerant. This could result in severe wounds caused by frostbite.

■ Electrical work must be carried out in accordance with the installation manual and the national electrical wiring rules or code of practice. Insufﬁcient capacity or incomplete electrical work may cause electrical shock or ﬁre.

■ Be sure to use a dedicated power circuit. Never use a power circuit shared by another appliance.

■ For wiring, use a cable long enough to cover the entire distance with no connection. Do not use an extension cord. Do not put other loads on the power supply, use a dedicated power circuit. Failure to do so may cause abnormal heat, electric shock, or ﬁre.

■ Do not touch the refrigerant pipes during and immediately after operation as the refrigerant pipes may be hot or cold, depending on the condition of the refrigerant ﬂowing through the refrigerant piping, compressor and other refrigerant cycle parts. Your hands may suffer burns or frostbite if you touch the refrigerant pipes. To avoid injury, give the pipes time to return to normal temperature or, if you must touch them, be sure to wear proper gloves.

CAUTION

■ For use of units in applications with temperature alarm settings it is advised to foresee a delay of 10 minutes for signalling the alarm in case the alarm temperature is exceeded. The unit may stop for several minutes during normal operation for "defrosting of the unit" or when in "thermostat-stop" operation.

■ Earth the unit. Earth resistance should be according to the applicable legislation. Do not connect the earth wire to gas or water pipes, lightning conductor or telephone earth wire. Incomplete earthing may cause electric shocks.

- Gas pipe.

Ignition or explosion may occur if the gas leaks.

-Water pipe.

Hard vinyl tubes are not effective earths.

- Lightning conductor or telephone earth wire.

Electric potential may rise abnormally if struck by a lightning bolt.

■ Install the indoor and outdoor units, power wire and connecting wire at least 1 meter away from televisions or radios to prevent image interference or noise. (Depending on the radio waves, a distance of 1 meter may not be sufﬁcient to eliminate the noise.)

■ Do not rinse the unit. This may cause electric shocks or ﬁre.

■ Do not install the unit in places such as the following:

- Where there is mist of mineral oil, oil spray or vapour.

Plastic parts may deteriorate, and cause them to fall out or water to leak.

- Where corrosive gas, such as sulphurous acid gas, is

produced. Corrosion of copper pipes or soldered parts may cause the refrigerant to leak.

- Where there is machinery which emits

electromagnetic waves. Electromagnetic waves may disturb the control system, and cause malfunction of the equipment.

- Where ﬂammable gases may leak, where carbon

ﬁbre or ignitable dust is suspended in the air or where volatile ﬂammables, such as thinner or gasoline, are handled. Such gases may cause a ﬁre.

- Where the air contains high levels of salt such as that

near the ocean.

- Where voltage ﬂuctuates a lot, such as that in

factories.

- In vehicles or vessels.

- Where acidic or alkaline vapour is present.

The ON/OFF setting of the heating/cooling operation is done by the user interface.

8.5. Application 5

Space heating with an auxiliary boiler (alternating operation)

Space heating application by either the Daikin unit or by an auxiliary boiler connected in the system. The decision whether either the EBHQ* unit or the boiler will operate can be achieved by an auxiliary contact or an EKCB* indoor controlled contact.

The auxiliary contact can e.g. be an outdoor temperature thermostat, an electricity tariff contact, a manually operated contact, etc. See

"Field wiring conﬁguration A" on page 10.

The EKCB* unit controlled contact (also called "permission signal for the auxiliary boiler") is determined by the outdoor temperature (thermistor located at the outdoor unit). See "Field wiring

conﬁguration B" on page 10.

Bivalent operation is only possible for space heating operation, not for the domestic water heating operation. Domestic hot water in such an application is always provided by the domestic hot water tank which is connected to the Daikin unit.

The auxiliary boiler must be integrated in the piping work and in the ﬁeld wiring according to the illustrations below.

Installation manual

Page 12

CAUTION

■ Be sure that the boiler and the integration of the boiler in the system is in accordance with the applicable legislation.

■ Always install a 3-way valve, even if no domestic hot water tank is installed. This to ensure that the freeze protection function (see "[4-04] Freeze protection

function" on page 27) can operate when the boiler is

active.

NOTICE

■ Conﬁguration A

Make sure that auxiliary contact (A) has sufﬁcient differential or time delay so as to avoid frequent changeover between the EBHQ* unit and the boiler. If the auxiliary contact (A) is an outdoor temperature thermostat, make sure to install the thermostat in the shade, so that it is not inﬂuenced or turned ON/OFF by the sun.

Conﬁguration B

Make sure that the bivalent hysteresis [C-04] has sufﬁcient differential to avoid frequent changeover between the EBHQ* unit and the boiler. As the outdoor temperature is measured via the outdoor unit’s air thermistor, make sure to install the outdoor unit in the shade, so that it is not inﬂuenced by the sun.

Frequent switching may cause corrosion of the boiler in an early stage. Contact the manufacturer of the boiler.

■ During heating operation of the EBHQ* unit, the unit will operate so as to achieve the target leaving water temperature as set on the user interface. When weather dependent operation is active, the water temperature is determined automatically depending on the outdoor temperature.

During heating operation of the boiler, the boiler will operate so as to achieve the target leaving water temperature as set on the boiler controller.

Never set the target leaving water temperature set point on the boiler controller above 55°C.

■ Make sure to only have 1 expansion vessel in the water circuit. An expansion vessel is already premounted in the unit.

8.6. Application 6

Space heating with room thermostat application through ﬂoor heating loops and fan coil units. The ﬂoor heating loops and fan coil units require different operating water temperatures.

The ﬂoor heating loops require a lower water temperature in heating mode compared to fan coil units. To achive these two set points, a mixing station is used to adapt the water temperature according to requirements of the ﬂoor heating loops. The fan coil units are directly connected to the unit water circuit and the ﬂoor heating loops after the mixing station. The control of this mixing station is not done by the unit.

The operation and conﬁguration of the ﬁeld water circuit is the responsibility of the installer.

Daikin only offers a dual set point control function. By this function two set points can be generated. Depending on the required water temperature (ﬂoor heating loops and/or fan coil units are required) ﬁrst set point or second set point can be activated.

NOTICE

Make sure to conﬁgure the DIP switch SS2-3 on the PCB of the EKCB(H/X)* switch box correctly. Refer to

"12.2. Room thermostat installation conﬁguration" on page 21.

For conﬁguration B: Make sure to conﬁgure the ﬁeld settings [C-02, C-03 and C-04] correctly. Refer to "Bivalent

operation" on page 32.

NOTICE

Make sure that return water to the EBHQ* heat exchanger never exceeds 55°C.

For this reason, never put the target leaving water temperature set point on the boiler controller above 55°C and install an aquastat

(a)

valve in the return water ﬂow of

the EBHQ* unit. Make sure that the non-return valves (ﬁeld supply) are

correctly installed in the system. Make sure that the room thermostat (th) is not frequently

turned ON/OFF. Daikin shall not be held liable for any damage resulting

from failure to observe this rule.

(a) The aquastat valve must be set for 55°C and must operate to close the return

water ﬂow to the unit when the measured temperature exceeds 55°C. When the temperature drops to a lower level, the aquastat valve must operate to open the return water ﬂow to the EBHQ* unit again.

INFORMATION

■ The advantage of the dual set point control is that the heat pump will/can operate at the lowest required leaving water temperature when only ﬂoor heating is required. Higher leaving water temperatures are only required in case fan coil units are operating. This results in a better performance of the heat pump.

■ The hydraulic balance is very important. (outdoor unit

- heater kit (if applicable) - mixing station - FCU1...3)

INFORMATION

Manual permission towards the EBHQ* unit on the boiler. In case only the EBHQ* unit should operate in space

heating mode, disable the bivalent operation via setting [C-02].

In case only the boiler should operate in space heating mode, increase the bivalent ON temperature [C-03] to 25°C.

■ It is the installers responsibility to make sure no unwanted situations can occur (e.g. too high water temperatures towards ﬂoor heating loops, etc.)

■ Daikin does not offer any type of mixing station. Dual set point control only provides the possibility to use two set points.

■ When only zone A requests heating, zone B will be fed with water at a temperature equal to the ﬁrst set point. This can lead to unwanted heating of zone B.

■ When only zone B requests heating, the mixing station will be fed with water at a temperature equal to the second set point. Depending on the control of the mixing station, the ﬂoor heating loop can still receive water at a temperature equal to set point of the mixing station.

■ Be aware that the actual water temperature through the ﬂoor heating loops depends on the control and setting of the mixing station.

Connection to a beneﬁt kWh rate power supply

Electricity companies throughout the world work hard to provide reliable electric service at competitive prices and are often authorized to bill clients at beneﬁt rates. E.g. time-of-use rates, seasonal rates, Wärmepumpentarif in Germany and Austria, ...

This equipment allows for connection to such beneﬁt rate power supply delivery systems.

Consult with the electricity company acting as provider at the site where this equipment is to be installed to know whether it is appropriate to connect the equipment in one of the beneﬁt kWh rate power supply delivery systems available, if any.

When the equipment is connected to such beneﬁt kWh rate power supply, the electricity company is allowed to:

■ interrupt power supply to the equipment for certain periods of time;

■ demand that the equipment only consumes a limited amount of electricity during certain periods of time.

The indoor unit is designed to receive an input signal by which the unit switches into forced off mode. At that moment, the outdoor unit compressor will not operate.

Possible types of beneﬁt kWh rate power supply

Possible connections and requirements to connect the equipment to such power supply are illustrated in the ﬁgure below:

Without room thermostat: DIP switch SS2-3 = OFF

When no thermostat is connected to the indoor unit, pump operation will be determined by the leaving water temperature.

To force continuous pump operation when no room thermostat is connected do the following:

- set toggle switch SS2-3 to ON,

- short-circuit the terminal numbers 1-2-4 on the terminal block in the switch box.

With room thermostat DIP switch: SS2-3 = ON

When the thermostat is connected to the indoor unit, the pump will operate continuously whenever there is heating or cooling demand requested by the thermostat.

Dual set point

When dual set point is enabled, the pump operation will be determined depending on the status of the DIP switch SS2-3 and set point selection contacts. Refer to the pump operation conﬁgurations when the thermostat is connected or not as described above.

INFORMATION

When dual set point is enabled, the "forced continuous pump operation" is not possible. When SS2-3 is ON while SP1 and SP2 are both closed, the pump operation will be the same operation as "with room thermostat" and the second set point will be the applicable set point. Refer to the table below.

12.5. Initial start-up at low outdoor ambient temperatures

During initial start-up and when water temperature is low, it is important that the water is heated gradually. Failure to do so may result in cracking of concrete ﬂoors due to rapid temperature change. Please contact the responsible cast concrete building contractor for further details.

To do so, the lowest leaving water set temperature can be decreased to a value between 15°C and 25°C by adjusting the ﬁeld setting [9-01] (heating set point lower limit). Refer to "12.9. Field settings" on

page 24.

INFORMATION

Heating between 15°C and 25°C is performed by the backup heater only (EKMBUH unit) (if installed).

INFORMATION

The function underﬂoor heating screed dry-out program offers the possibility to execute automatically the gradual heat up. See "13.3. Underﬂoor heating screed dry-out

program" on page 39.

11 Air purge valve

Make sure the air purge valve is open (at least 2 turns).

12 Pressure relief valve

Check if the backup heater is completely ﬁlled with water by operating the pressure relief valve. It should purge water instead of air.

NOTICE

Operating the system with closed valves will damage the pump!

12.7. Powering up the indoor unit

When power supply to the outdoor unit is turned on (provided power supply via the outdoor unit) , "88" is displayed on the user interface during its initialisation, which might take up to 30 seconds. During this process the user interface cannot be operated.

12.8. Setting the pump speed

The pump speed can be selected on the pump (see the chapter

"Main components of the outdoor unit" in the EBHQ outdoor unit installation manual).

The default setting is high speed (III). If the water ﬂow in the system is too high (e.g., noise of running water in the installation) the speed can be set to medium speed (II) or low speed (I).

[3] Auto restart

When power returns after a power supply failure, the auto restart function reapplies the user interface settings at the time of the power supply failure.

NOTICE

It is therefore recommended to leave the auto restart function enabled.

Note that with the function disabled the schedule timer will not be activated when power returns to the unit after a power supply failure. Press the pr button to enable the schedule timer again.

■ [3-00] Status: deﬁnes whether the auto restart function is

NOTICE

If the beneﬁt kWh rate power supply is of the type that power supply is interrupted, then always allow the auto restart function.

INFORMATION

Continuous indoor unit control can be guaranteed independent of the beneﬁt kWh rate power supply status, by connecting the indoor unit to a normal kWh rate power supply. See "Connection to a beneﬁt kWh rate power

supply" on page 20.

[4] Backup/booster heater operation and space heating off

temperature

Backup heater operation (if installed)

The operation of the backup heater (EKMBUH unit) can altogether be enabled or disabled, or it can be disabled depending on operation of the booster heater.

■ [4-00] Status: deﬁnes whether backup heater operation is enabled (1) or disabled (0).

■ [4-01] Priority: deﬁnes whether backup heater and booster heater can operate simultaneously (0), or if the booster heater operation has priority over the backup heater operation (1), or if the backup heater operation has priority over the booster heater operation (2).

INFORMATION

When the priority ﬁeld setting is set to ON (1), space heating performance of the system might be decreased at low outdoor temperatures, since in case of domestic water heating demand the backup heater will not be available for space heating (space heating will still be provided by the heat pump).

When the priority ﬁeld setting is set to ON (2), domestic water heating performance of the system might be decreased at low outdoor temperatures, since in case of space heating demand the booster heater will not be available for domestic water heating. However domestic water heating by heat pump will still be available.

NOTICE

When the priority ﬁeld setting is set to OFF (0), make sure that electrical power consumption does not exceed supply limits.

Booster heater operation

Applies only to installations with a domestic hot water tank.

The operation of the booster heater can be enabled or limited depending on outdoor temperature (TA), domestic hot water temperature (T

) or operation mode of the heat pump.

DHW

■ [4-03] Booster heater operation: deﬁnes whether the optional booster heater operation is enabled (1) or has certain limitations (0/2/3/4).

Explanation of settings of [4-03]

Booster heater will/can only operate if domestic hot water mode is activated (w).

■ [4-03]=0, then booster heater operation is only allowed during "[2] Disinfection function" and "Powerful domestic water heating" (see operation manual). This setting is only recommended in case the capacity of the heat pump can cover the heating requirements of the house and domestic hot water over the complete heating season. The result of this setting is that the domestic hot water will never be heated by the booster heater except for "[2] Disinfection function" and "Powerful domestic water heating" (see operation manual).

INFORMATION

If the booster heater operation is limited ([4-03]=0) and the ambient outdoor temperature TA is lower than the ﬁeld setting to which parameter [5-03] is set and [5-02]=1, then the domestic hot water will not be heated.

The consequence of this setting is that the domestic hot water temperature (T heat pump OFF temperature (T

) can be maximum the

DHW

HP OFF

). Refer to

setting of [6-00] and [6-01] in "[6]" on page 28.

■ [4-03]=1, then booster heater heater operation is only determined by booster heater OFF temperature (T booster heater ON temperature (T

) and/or schedule

timer. Refer to setting "[7-00]" on page 29 and "[7-01]" on

page 29.

■ [4-03]=2, then booster heater operation is only allowed if heat pump is out of "operation range" of heat pump domestic water heating mode (TA<[5-03] or TA>35°C) or domestic hot water temperature is 2°C lower then the heat pump OFF temperature (T (T

DHW>THP OFF

) for domestic hot water mode

HP OFF

–2°C). (Refer to setting [5-03] on page 27,

[6-00] on page 28 and [6-01] on page 28). Results in the most optimum coverage of domestic hot water

heated by the pump.

■ [4-03]=3, then booster heater operation is the same as setting 1, except that booster heater is OFF when the heat pump is active in domestic hot water mode. The consequence of this functionality is that setting [8-03] is not relevant. Results in optimum coverage of domestic hot water heated by heat pump in relation with [8-04].

INFORMATION

■ When setting [4-03]=1/2/3/4, the booster heater operation can still be restricted by the schedule timer as well. I.e., when booster heater operation is preferred during certain period of the day. (See operation manual)

■ When setting [4-03]=2, the booster heater will be allowed to operate when T

<[5-03] independent

of the status of [5-02]. If bivalent operation is enabled and permission signal for auxiliary boiler is ON, the booster heater will be restricted even when TA<[5-03]. (See "[C-02]" on page 32).

■ Booster heater is always allowed during powerful and disinfection function, except for the period that the backup heater operation is required for safety reasons and [4-02]=1.

■ [4-03]=4, then booster heater operation is the same as setting 2, except that the domestic water heating (heat pump and booster) will operate according to the scheduled storage and reheat function. See ﬁeld settings "[6-03]" on page 28 and "[6-05]" on page 28.

CAUTION

For optional domestic hot water tank, the ﬁeld setting [4-03] shall be 0, 1, 2, 3, or 4.

INFORMATION

■ [4-03]=3 (default), this setting is automatically selected if the correct and complete wiring connections between indoor unit and switch box of the optional domestic hot water tank are done BEFORE SS2-2 is set to ON. [4-03]=0~4 activate the applicable logic and ﬁeld settings for EKHW*.

■ [4-03]=5, this setting is automatically selected in case there is incorrect ﬁeld wiring between indoor unit and switch box of the optional domestic hot water tank (for example when booster heater is not connected). The required corrective action is described in

"Symptom 9: Field setting [4-03] and relation to possible wrong tank temperatures" on page 42.

■ [4-02] Space heating off temperature: outdoor temperature above which space heating is turned off, to avoid overheating.

■ [4-04] Freeze protection function: avoids freezing of the water piping between home and unit. In case of low ambient temperatures it will activate the pump and in case of low water temperatures it will additionally activate the backup heater (if installed).

Default freeze protection function takes into account freezing of water piping which is insufﬁciently insulated.

Basically it means that the pump is activated whenever ambient temperatures become close to freezing, independently of the working temperature.

■ Only if EKMBUH is installed [4-06] Backup heater emergency operation: deﬁnes whether backup heater is allowed (1) or not allowed (0) during emergency operation.

Emergency operation will startup backup heater operation during certain outdoor malfunctions.

■ Only if EKMBUH is installed [4-07] Backup heater second step: deﬁnes whether backup heater second step is allowed (1) or not allowed (0).

In this way it is possible to limit the backup heater capacity.

When the equilibrium temperature function is enabled, operation of the backup heater is restricted to low outdoor temperatures, i.e. when the outdoor temperature equals or drops below the speciﬁed equilibrium temperature. When the function is disabled, operation of the backup heater is possible at all outdoor temperatures. Enabling this function reduces the working time of the backup heater.

■ [5-00] Equilibrium temperature status: speciﬁes whether the equilibrium temperature function is enabled (1) or disabled (0).

■ [5-01] Equilibrium temperature: outdoor temperature below which operation of the backup heater is allowed.

Space heating priority temperature

— Applies only to installations

with a domestic hot water tank. — The 'space heating priority temperature' ﬁeld settings apply to operation of the 3-way valve and the booster heater in the domestic hot water tank.

When the space heating priority function is enabled, it is assured that the full capacity of the heat pump is used for space heating only when the outdoor temperature equals or drops below the speciﬁed space heating priority temperature, i.e. low outdoor temperature. In this case the domestic hot water will only be heated by the booster heater.

■ [5-02] Space heating priority status: speciﬁes whether space heating priority is enabled (1) or disabled (0).

■ [5-03] Space heating priority temperature: outdoor temperature below which the domestic hot water will be heated by the booster heater only, i.e. low outdoor temperature.

INFORMATION

If the booster heater operation is limited ([4-03]=0) and the ambient outdoor temperature T

is lower than

the ﬁeld setting to which parameter [5-03] is set and [5-02]=1, then the domestic hot water will not be heated.

■ [5-04] Set point correction for domestic hot water temperature: set point correction for the desired domestic hot water temperature, to be applied at low outdoor temperature when space heating priority is enabled. The corrected (higher) set point will make sure that the total heat capacity of the water in the tank remains approximately unchanged, by compensating for the colder bottom water layer of the tank (because the heat exchanger coil is not operational) with a warmer top layer.

INFORMATION

■ Make sure that the domestic hot water set point is according to your requirements. Start with a low domestic hot water storage set point, and only increase if you feel that the domestic hot water supply temperature is not sufﬁcient for your requirements (this depends on your water using pattern).

■ Make sure the domestic water is not heated unnecessary. Start with activating automatic storage during night (default setting). If it seems that the scheduled storage domestic water heating during the night is not sufﬁcient for your requirements, an additional scheduled reheat during daytime can be set.

[7] DT for booster heater and dual set point control

DT for booster heater

Applies only to installations with a domestic hot water tank.

When the domestic hot water is heated and the domestic hot water set point temperature (as set by the user) has been reached, the booster heater will continue to heat the domestic hot water to a temperature a few degrees above the set point temperature, i.e. the booster heater OFF temperature. These extra degrees are speciﬁed by the domestic hot water step length ﬁeld setting. Correct setting prevents the booster heater from repeatedly turning on and off (i.e. chattering) to maintain the domestic hot water set point temperature. Note: the booster heater will turn back on when the domestic hot water temperature drops [7-01] (ﬁeld setting) below the booster heater OFF temperature.

INFORMATION

If the schedule timer for booster heater (see the operation manual) is active, the booster heater will only operate if allowed by this schedule timer.

- In cooling mode the ﬁrst set point is always a ﬁxed

value.

■ The second set point heating [7-03] should be linked to the heat emitters which requires the highest set point in heating mode. Example: fan coil unit.

■ The second set point cooling [7-04] should be linked to the heat emitters which requires the lowest set point in cooling mode. Example: fan coil unit.

■ The actual second set point heating value depends on the selected value of setting [7-03].

- In case [7-03]=1~24, the actual second set point

will be ﬁrst set point heating increased with [7-03] (the maximum is 55°C). In this way the second set point heating is linked to the ﬁrst set point heating.

- In case [7-03]=25~55, the actual second set point

[8] Domestic water heating mode timer

Applies only to installations with a domestic hot water tank.

The 'domestic water heating mode timer' ﬁeld settings deﬁnes the minimum and maximum domestic water heating times, minimum time between two domestic water heating cycles by heat pump, and booster heater delay time.

■ [8-00] Minimum running time: speciﬁes the minimum time period during which heat pump domestic water heating mode should be activated, even when the target domestic hot water temperature for heat pump (T

) has already been

HP OFF

reached.

■ [8-01] Maximum running time: speciﬁes the maximum time period during which heat pump domestic water heating mode can be activated, even when the target domestic hot water temperature for heat pump (T

) has not yet been

HP OFF

reached. The actual maximum running time will automatically variate between [8-01] and [8-01]+[8-04] depending on the outdoor temperature. See ﬁgure in chapter "[8-04]" on page 31.

INFORMATION

Note that when the unit is conﬁgured to work with a room thermostat (refer to "12.2. Room thermostat

installation conﬁguration" on page 21), the maximum

running timer will only be taken into account when there is a request for space heating or space cooling. When there is no request for space heating or space cooling, domestic water heating by the heat pump will continue until the 'heat pump OFF temperature' (see ﬁeld settings [6] on page 28) is reached. When no room thermostat is installed, the timer is always taken into account.

INFORMATION

When dual set point control is enabled, heating/cooling selection always has to be done on the user interface.

NOTICE

It is the responsibility of the installer to make sure no unwanted situations can occur.

It is very important that the water temperature to the ﬂoor heating loops never becomes too high in heating mode or never too cold in cooling mode. Failure to observe this rule can result in construction damage or discomfort. For example in cooling mode condensation on the ﬂoor can occur when water towards the ﬂoor heating loops is too cold (dew point).

■ [8-02] Anti-recycling time: speciﬁes the minimum required interval between two heat pump domestic water heating mode cycles. The actual anti-recycling time will automatically variate between [8-02] and 0 depending on the outdoor temperature. See ﬁgure in chapter "[8-04]" on page 31.

INFORMATION

■ By adapting the booster heater delay time versus the maximum running time, an optional balance can be found between the energy efﬁciency and the heat up time.

■ However, if the booster heater delay time is set too high, it might take a long time before the domestic hot water reaches its set temperature upon domestic hot water mode request.

■ The purpose of [8-03] is to delay the booster heater in relation with the heat pump operation time in domestic water heating mode.

■ The setting [8-03] has only meaning if setting [4-03]=1. Setting [4-03]=0/2/3/4 limits the booster heater automatically in relation to heat pump operation time in domestic water heating mode.

The purpose of this ﬁeld setting is to prevent the user from selecting a wrong (i.e., too hot or too cold) leaving water temperature. Thereto the heating temperature set point range and the cooling temperature set point range available to the user can be conﬁgured.

CAUTION

■ In case of a ﬂoor heating application, it is important to limit the maximum leaving water temperature at heating operation according to the speciﬁcations of the ﬂoor heating installation.

■ In case of a ﬂoor cooling application, it is important to limit the minimum leaving water temperature at cooling operation (ﬁeld setting of parameter [9-03]) to 16~18°C to prevent condensation on the ﬂoor.

■ [9-00] Heating set point upper limit: maximum leaving water temperature for heating operation.

■ [9-01] Heating set point lower limit: minimum leaving water temperature for heating operation.

■ [9-02] Cooling set point upper limit: maximum leaving water temperature for cooling operation.

■ [9-03] Cooling set point lower limit: minimum leaving water temperature for cooling operation.

■ [9-04] Overshoot setting: deﬁnes how much the water temperature may rise above the set point before the compressor stops. This function is only applicable in heating mode.

Automatic setback function

Setback function provides the possibility to lower the water temperature during space heating. The setback function can for instance be activated during the night because the temperature demands during night and day are not the same.

INFORMATION

■ Remark that the b icon will be ﬂashing during setback operation. The calculated leaving water setback set point is not shown during setback operation.

■ By default the setback function is disabled.

■ The setback function can be combined with the

Change the "user permission level" ﬁeld setting [0-00], see "12.9. Field

settings" on page 24.

Symptom 7: Space heating capacity shortage at low outdoor temperatures

POSSIBLE CAUSES CORRECTIVE ACTION

Backup heater operation is not activated.

The backup heater equilibrium temperature has not been conﬁgured correctly.

Too much heat pump capacity is used for heating domestic hot water (applies only to installations with a domestic hot water tank).

Check that the "backup heater operation status" ﬁeld setting [4-00] is turned on, see "12.9. Field

settings" on page 24.

Check whether or not the thermal protector of the backup heater has been activated (refer to "5.2. Main

components of the indoor unit" on page 5, "Backup heater thermal

protector" in the installation manual of the EKMBUH for location of the reset button). Check if booster heater and backup heater are conﬁgured to operate simultaneously (ﬁeld setting [4-01], see "12.9. Field settings" on

page 24)

Check whether or not the thermal fuse of the backup heater is blown (refer to "5.2. Main components of

the indoor unit" on page 5, "Backup

heater thermal fuse" in the installation manual of the EKMBUH for location of the reset button).

Raise the ﬁeld setting [5-01] to activate backup heater operation at a higher outdoor temperature.

Check that the temperature' ﬁeld settings are conﬁgured appropriately: Make sure that the 'space heating priority status' ﬁeld setting [5-02] is enabled. Raise the 'space heating priority temperature' ﬁeld setting [5-03] to activate booster heater operation at a higher outdoor temperature.

'equilibrium temperature'

'space heating priority

Symptom 8: Temperature values displayed on the remote controller (user interface) are displayed in °F instead of °C

POSSIBLE CAUSES CORRECTIVE ACTIONS

You accidentally changed the setting to view the temperature values in °F by pushing the ib and jb buttons simultaneously.

To change the display back to °C, push ib and jb buttons simultaneously for 5 seconds. Execute same procedure to change back to the °F display. The default temperature display is in °C.

Symptom 9: Field setting [4-03] and relation to possible wrong tank temperatures

Typical symptoms:

■ ﬁeld setting [4-03] has value 5,

■ maximum domestic hot water set point is limited to 60°C,

■ tank temperature sensor reads out wrong values.

POSSIBLE CAUSES CORRECTIVE ACTIONS

When dip switch SS2-2 is switched to ON, the unit automatically tries to detect the correct tank connections (booster heater, thermal protector,...). In case of wrong ﬁeld wiring or wrong tank type connection, the automatic detection will result in wrong values for [4-03] and related tank temperatures.

Check and correct if necessary all ﬁeld wiring between indoor unit and tank.

RESET

•Power OFF the indoor unit and switch SS2-2 to OFF.

•Power ON the indoor unit. Since SS2-2 is OFF, the unit will not detect any hot water tank.

•Power OFF the indoor unit and switch SS2-2 back to ON.

•Power ON the indoor unit. The indoor unit will now try to detect the tank again. When all ﬁeld wiring is correct, ﬁeld setting [4-03] should be automatically set to its default value

3. Tank temperatures and maximum domestic hot water set point should now be correct.
