Under floor heating or radiators – Thermostatic valves

If you are heating up rooms with under floor heating or radiators, a very common way is to control the temperature of the main room by using a thermostat (this can either be the user interface or an external room thermostat), while the other rooms are controlled by so-called thermostatic valves, which open or close depending on the room temperature.

Setup

5.3 Setting up an auxiliary heat source for space

heating

Q Space heating can be done by:

Q The indoor unit

Q An auxiliary boiler (field supply) connected to the system Q When the room thermostat requests heating, the indoor unit or

the auxiliary boiler starts operating depending on the outdoor

temperature (status of the changeover to external heat source).

When the permission is given to the auxiliary boiler, the space

heating by the indoor unit is turned OFF.

Q Bivalent operation is only possible for space heating, NOT for

domestic hot water production. Domestic hot water is always

produced by the DHW tank connected to the indoor unit.

INFORMATION

Q During heating operation of the heat pump, the

heat pump operates to achieve the desired temperature set via the user interface. When weatherdependent operation is active, the water temperature is determined automatically depending on the outdoor temperature.

Q During heating operation of the auxiliary boiler, the

auxiliary boiler operates to achieve the desired water temperature set via the auxiliary boiler controller.

Setup

Q Integrate the auxiliary boiler as follows:

5.4.3 Selecting the volume and desired temperature for the DHW tank

People experience water as hot when its temperature is 40°C. Therefore, the DHW consumption is always expressed as equivalent hot water volume at 40°C. However, you can set the DHW tank temperature at a higher temperature (example: 53°C), which is then mixed with cold water (example: 15°C). Selecting the volume and desired temperature for the DHW tank consists of:

1 Determining the DHW consumption (equivalent hot water

volume at 40°C).

2 Determining the volume and desired temperature for the DHW

tank.

Possible DHW tank volumes

Typ e Possible volumes

Integrated DHW tank

Standalone DHW tank

Energy saving tips

Q If the DHW consumption differs from day to day, you can

program a weekly schedule with different desired DHW tank temperatures for each day.

Q The lower the desired DHW tank temperature, the more cost

effective. By selecting a larger DHW tank, you can lower the desired DHW tank temperature.

Q The heat pump itself can produce domestic hot water of

maximum 55°C (50°C if outdoor temperature is low). The electrical resistance integrated in the heat pump can higher this temperature. However, this consumes more energy. Daikin recommends to set the desired DHW tank temperature below 55°C to avoid using the electrical resistance.

Q The higher the outdoor temperature, the better the performance

of the heat pump.

Q 180 l Q 260 l

Q 150 l Q 200 l Q 300 l

Q If energy prices are the same during the day and the night,

Daikin recommends to heat up the DHW tank during the day.

Q If energy prices are lower during the night, Daikin

recommends to heat up the DHW tank during the night.

Q When the heat pump produces domestic hot water, it cannot

heat up a space. When you need domestic hot water and space heating at the same, Daikin recommends to produce the domestic hot water during the night when there is lower space heating demand.

Determining the DHW consumption

Answer the following questions and calculate the DHW consumption (equivalent hot water volume at 40°C) using the typical water volumes:

Question Typical water volume

How many showers are needed per day?

How many baths are needed per

1 shower = 10 min x 10 l/min = 100 l

1 bath = 150 l

day?

How much water is needed at the

1sink = 2min x 5l/min = 10l

kitchen sink per day?

Are there any other domestic hot

—

water needs?

Example: If the DHW consumption of a family (4 persons) per day is as follows:

Q 3 showers Q 1 bath Q 3 sink volumes

Then the DHW consumption = (3x100 l) + (1x150 l) + (3x10 l) = 480 l

Determining the volume and desired temperature for the DHW tank

Formula Example

= V2 + V2x (T2- 40) / (40 - T1) If:

= V1 x (40 - T1)/ (T2-T1) If:

V1: DHW consumption (equivalent hot water volume at 40°C) V2: Required DHW tank volume if only heated once T2: DHW tank temperature T1: Cold water temperature

5.4.4 Setup and configuration – DHW tank

Q For large DHW consumptions, you can heat up the DHW tank

several times during the day.

Q To heat up the DHW tank to the desired DHW tank temperature,

you can use the following energy sources:

Q Thermodynamic cycle of the heat pump Q Electrical backup heater (for integrated DHW tank) Q Electrical booster heater (for standalone DHW tank) Q Solar panels

Q For more information about:

Q Optimizing the energy consumption for producing domestic

hot water, see the configuration chapter.

Q Connecting the electrical wiring of the standalone DHW

tank to the indoor unit, see the installation chapter.

Q Connecting the water piping of the standalone DHW tank to

the indoor unit, see the installation manual of the DHW tank.

5.6.1 Permanent power limitation

Permanent power limitation is useful to assure a maximum power or current input of the system. In some countries, legislation limits the maximum power consumption for space heating and DHW production. Example: The maximum power input depends on the area of the house and an annual fee has to be paid to the electrical company according to the size of the installed field fuse. By permanently limiting the maximum power or current of the system, you can install smaller field fuses.

NOTICE

When the current control is intended to reduce the installed field fuse sizes, the field fuse will trip to protect the field wires in case of overcurrents caused by the unit. Make sure the selection of the field fuse complies with applicable legislation.

5.6.2 Power limitation activated by digital inputs

Power limitation is also useful in combination with an energy management system. The power or current of the entire Daikin system is limited dynamically by digital inputs (maximum four steps). Each power limitation level is set via the user interface by limiting one of the following:

Q Current (in A) Q Power input (in kW)

The energy management system (field supply) decides the activation of a certain power limitation level. Example: To limit the maximum power of the entire house (lighting, domestic appliances, space heating…).

5.7 Setting up an external temperature sensor

You can connect one external temperature sensor. It can measure the indoor or outdoor ambient temperature. Daikin recommends to use an external temperature sensor in the following cases:

Indoor ambient temperature

Q In room thermostat control, the user interface is used as room

thermostat and it measures the indoor ambient temperature. Therefore, the user interface must be installed on a location:

Q Where the average temperature in the room can be

detected

Q That is NOT exposed to direct sunlight Q That is NOT near a heat source Q That is NOT affected by outside air or air draught because

of, for example, door opening/closing

Q If this is NOT possible, Daikin recommends to connect a remote

indoor sensor (option KRCS01-1).

Q Setup: For installation instructions, see the installation manual of

the remote outdoor sensor.

Q Configuration: Select room sensor [A.2.2.B].

Outdoor ambient temperature

Q In the outdoor unit, the outdoor ambient temperature is

measured. Therefore, the outdoor unit must be installed on a location:

Q At the north side of the house or at the side of the house

where the most heat emitters are located

Q That is NOT exposed to direct sunlight

Q If this is NOT possible, Daikin recommends to connect a remote

outdoor sensor (option EKRSCA1).

Q Setup: For installation instructions, see the installation manual of

the remote outdoor sensor.

Q Configuration: Select outdoor sensor [A.2.2.B]. Q During suspend (see configuration), the outdoor unit is turned

down to reduce the standby energy losses. As a result, the outdoor ambient temperature is NOT read out.

Q If the desired leaving water temperature is weather dependent,

the full time outdoor temperature measurement is important. This is another reason to install the optional outdoor ambient temperature sensor.

INFORMATION

The external outdoor ambient sensor data (either averaged or instantaneous) is used in the weather-dependent control curves and in the automatic heating/cooling changeover logic. To protect the outdoor unit, the internal sensor of the outdoor unit is always used.

6.2 Preparing water piping

6.2.1 Water circuit requirements

Q Use the indoor unit only in a closed water system.

Using the system in an open water system will lead to excessive corrosion.

Q The maximum water pressure is 4 bar.

Provide adequate safeguards in the water circuit to ensure that the maximum pressure is NOT exceeded.

Q All installed piping and piping accessories (valve,

connections,…) must withstand the following temperatures:

INFORMATION

The following illustration is an example and may NOT match your system layout.

Do NOT install the unit in places such as:

Q 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.

Q Do NOT install the unit in sound sensitive areas (e.g. near a

bedroom and the like), so that the operation noise will cause no trouble. Note: If the sound is measured under actual installation conditions, the measured value will be higher than the sound pressure level mentioned in Sound spectrum due to environmental noise and sound reflections.

Q The foundation must be strong enough to bear the weight of the

unit. Take the weight of the unit with a domestic hot water tank full of water into account. Make sure, in the event of a water leak, water cannot cause any damage to the installation space and surroundings.

Q In places with high humidity (max. RH=85%), for example a

bathroom.

Q In places where frost is possible. Ambient temperature around

the indoor unit should be >5°C.

Q The indoor unit is designed for indoor installation only and for

ambient temperatures ranging 5~35°C in cooling mode and 5~30°C in heating mode.

Q Only use materials that are compatible with water used in the

system and with the materials used in the indoor unit.

Q Check that all components in the field piping can withstand the

water pressure and water temperature.

Q When using non-brass metallic piping, insulate the brass and

non-brass properly so that they do NOT make contact with each other. This to prevent galvanic corrosion.

Q Never use Zn-coated parts in the water circuit. Because the

unit's internal water circuit uses copper piping, excessive corrosion may occur.

Q Only use appropriate tooling to handle brass, which is a soft

material. If NOT, pipes will get damaged.

Q Select the water piping diameter in relation to the required water

flow and the available external static pressure of the pump. See "14 Technical data" on page 61 for the external static pressure curves of the indoor unit.

Q You can find the minimum required water flow for the indoor unit

operation in the following table. When the water flow is lower, flow error 7H will be displayed and the indoor unit will be stopped.

Q When using a 2-way valve in the water circuit, the maximum

change-over time of the valve must be 60 seconds.

Q It is strongly recommended to install an additional filter on the

heating water circuit. Especially to remove metallic particles from the filed heating piping, it is advised to use a magnetic or cyclone filter, which can remove small particles. Small particles may damage the unit and will NOT be removed by the standard filter of the heat pump system.

Q If air, moisture or dust gets into the water circuit, problems may

occur. To prevent this:

Q Only use clean pipes Q Hold the pipe end downwards when removing burrs. Q Cover the pipe end when inserting it through a wall, to

prevent dust and/or particles entering the pipe.

Q Use a decent thread sealant to seal connections.

Q For safety reasons, it is NOT allowed to add any kind of glycol to

the water circuit.

Q To avoid stagnation of water, it is important that the storage

capacity of the domestic hot water tank meets the daily consumption of domestic hot water. In cases where during longer periods of time there is no consumption of hot water, the equipment must be flushed with fresh water before usage. The disinfection function provided on the equipment is specified in the operation manual of the indoor unit.

Q It is recommended to avoid long runs of piping between the

domestic hot water tank and the hot water end point (shower, bath,…) and to avoid dead ends.

Q The installation must be in compliance with the applicable

legislation and may require additional hygienic installation measures.

Q In accordance with the applicable legislation, it may be

necessary to install thermostatic mixing valves.

Q Immediately after installation, the domestic hot water tank must

be flushed with fresh water. This procedure must be repeated at least once a day the first 5 consecutive days after installation.

Q In accordance with the applicable legislation, it may be required

to connect a recirculation pump in between the hot water end point and the recirculation connection of the domestic hot water tank.

6.2.2 Formula to calculate the expansion vessel pre-pressure

The pre-pressure (Pg) of the vessel depends on the installation height difference (H):

Pg=0.3+(H/10) (bar)

6.2.3 To check the water volume

The indoor unit has an expansion vessel of 10 litre with a factory set pre-pressure of 1 bar. To make sure that the unit operates properly:

Q You must check the minimum and maximum water volume. Q You might need to adjust the pre-pressure of the expansion

vessel.

Minimum water volume

Check that the total water volume in the installation is minimum 20 liter, the internal water volume of the indoor unit NOT included.

INFORMATION

In critical processes, or in rooms with a high heat load, extra water might be required.

NOTICE

When circulation in each space heating loop is controlled by remotely controlled valves, it is important that the minimum water volume is guaranteed, even if all of the valves are closed.

Do the following:

Q Decrease the pre-

pressure.

Q Check if the water

volume does NOT exceed the maximum allowed water volume.

The expansion vessel of the indoor unit is too small for the installation.

Example 2

The indoor unit is installed at the highest point in the water circuit. The total water volume in the water circuit is 350 l. Actions:

Q Because the total water volume (350 l) is more than the default

water volume (280 l), the pre-pressure must be decreased.

Q The required pre-pressure is:

Pg = (0.3+(H/10)) bar = (0.3+(0/10)) bar=0.3 bar.

Q The corresponding maximum water volume at 0.3 bar is 410 l.

(See the graph in the chapter above).

Q Because 350 l is lower than 410 l, the expansion vessel is

appropriate for the installation.

6.3.2 About preferential 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 preferential kWh rate power supply delivery systems.

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

Q interrupt power supply to the equipment for certain periods of

time;

Q 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. Whether the power supply is interrupted or not, the wiring to the unit is different.

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 preferential kWh rate power supply delivery systems available, if any.

7.3.1 To connect the water piping

NOTICE

Do NOT use excessive force when connecting the piping. Deformation of the piping can cause malfunctioning of the unit.

NOTICE

To avoid damage to the surroundings in case of water leakage, it is recommended to close the cold water inlet stop valves during periods of absence.

2 Screw the indoor unit nuts on the shut-off valves. 3 Connect the domestic hot water in and out pipes to the indoor

unit.

NOTICE

Q A drain device and pressure relief device should be

installed on the cold water inlet connection of the domestic hot water cylinder.

Q To avoid back siphonage, it is recommended to install

a non-return valve on the water inlet of the domestic hot water tank in accordance with the applicable legislation.

Q It is recommended to install a pressure reducing valve

on the cold water inlet in accordance with the applicable legislation.

Q An expansion vessel should be installed on the cold

water inlet in accordance with the applicable legislation.

Q It is recommended to install the pressure relief valve

on higher position as top of the domestic hot water tank. Heating of the domestic hot water tank causes water to expand and without pressure relief valve the water pressure inside the tank can rise above the tank design pressure. Also the field installation (piping, tapping points, etc.) connected to the tank is subjected to this high pressure. To prevent this, a pressure relieve valve needs to be installed. The overpressure prevention depends on the correct operation of the field installed pressure relief valve. If this is NOT working correctly, overpressure will deform the tank and water leakage may occur. To confirm good operation, regular maintenance is required.

7.3.2 To connect the pressure relief valve to the drain

The blow out of the pressure relief valve is coming out of the backside of the unit.

To facilitate service and maintenance, 2 shut-off valves are provided. Mount the valves on the water inlet and on the water outlet. Mind their the position. Orientation of the integrated drain and fill valves is important for servicing.

Leaving water temperature: Delta T emitter

Temperature difference for entering and leaving water. The unit is designed to support under floor loops operation. The recommended leaving water temperature (set by the user interface) for under floor loops is 35°C. In such case, the unit will be controlled to realize a temperature difference of 5°C which means that the entering water to the unit is around 30°C. Depending on the installed application (radiators, heat pump convector, under floor loops) or situation, it can be possible to change the difference between entering and leaving water temperature. Note that the pump will regulate its flow to keep the ∆t.

Leaving water temperature: Modulation

Only applicable in case of room thermostat control. When using the room thermostat functionality, the customer needs to set the desired room temperature. The unit will supply hot water to the heat emitters and the room will be heated. Additionally, also the desired leaving water temperature must be configured: when turning on the modulation, the desired leaving water temperature will be calculated automatically by the unit (based on the preset temperatures, if weather-dependent is selected, modulation will be done based on the desired weather-dependent temperatures); when turning off the modulation, you can set the desired leaving water temperature on the user interface. Moreover, with the modulation turned on, the desired leaving water temperature is lowered or raised in function of the desired room temperature and the difference between the actual and the desired room temperature. This results in:

Q stable room temperatures exactly matching the desired

temperature (higher comfort level)

Q less On/OFF cycles (lower noise level, higher comfort and

higher efficiency)

Q water temperatures as low as possible to match the desired

temperature (higher efficiency)

Readout the desired tank temperature

The desired tank temperature is displayed on the user interface. By the following settings, you can configure the way the tank temperature is displayed:

Q by its numerical value Q by an equivalent.

Use the numerical value in case the understanding of tank temperature is clear for the customer. On the user interface the customer can set the desired tank temperature by 1°C. For customers with less feeling about tank temperatures, choose display by equivalent number of people. They will set the desired tank temperature by indicating their domestic hot water consumption as a number of people.

As installer, you configure the conversion between the real desired tank temperature and the number of people taking into account the installed tank size and the daily domestic hot water consumption of the customer. Additionally, using the graphical display, the customer is made aware about the amount of consumed domestic hot water.

Preset leaving water temperature

You can define preset leaving water temperature temperatures:

Q economic (denotes the desired leaving water temperature which

results in the lowest energy consumption)

Q comfort (denotes the desired leaving water temperature

temperature which results in the highest energy consumption). Preset values make it easy to use the same value in the schedule or to adjust the desired leaving water temperature according to the room temperature (see modulation). If you later want to change the

value, you only have to do it in one place. Depending on whether the desired leaving water temperature is weather dependent or not, the absolute desired leaving water temperature should be specified or the desired shift values.

NOTICE

The preset leaving water temperature temperatures are only applicable for the main zone, as the schedule for the additional zone consists of On/OFF actions.

NOTICE

Select preset leaving water temperatures in accordance with the design and selected heat emitters to ensure the balance between desired room and leaving water temperatures.

NOTICE

Q When adjusting the leaving water temperature ranges,

all desired leaving water temperatures are also adjusted to guarantee they are between the limits.

Q Always balance between the desired leaving water

temperature with the desired room temperature and/or the capacity (according to the design and selection of the heat emitters). The desired leaving water temperature is the result of several settings (preset values, shift values, weather dependent curves, modulation). As a result, too high or too low leaving water temperatures could occur which lead to overtemperatures or capacity shortage. By limiting the leaving water temperature range to adequate values (depending on the heat emitter), such situations can be avoided.

Example: Set the minimum leaving water temperature to 28°C to avoid NOT to be able to heat up the room: leaving water temperatures must be sufficient higher than the room temperatures (in heating).

This function defines how much the water temperature may rise above the desired leaving water temperature before the compressor stops. The compressor will startup again when the leaving water temperature drops below the desired leaving water temperature. This function is only applicable in heating mode.

Leaving water temperature compensation around 0°C

In heating operation, the desired leaving water temperature is locally increased around an outdoor temperature of 0°C. This compensation can be selected when using an absolute or a weather dependent desired temperature, this compensation can be selected (see illustration below). Use this setting to compensate for possible heat losses of the building when the outdoor temperature is around 0°C (e.g. in cold region countries).

Leaving water temperature maximum modulation

Only applicable in room thermostat control and when modulation is enabled. The maximum modulation (=variance) on the desired leaving water temperature decided on the difference between the actual and desired room temperature, e.g. 3°C modulation means the desired leaving water temperature can be increased or lowered by 3°C. Increasing the modulation results in better performance (less On/OFF, faster heat up), but note that depending on the heat emitter, there must always be a balance (refer to the design and selection of the heat emitters) between the desired leaving water temperature and the desired room temperature.

Automatic heating/cooling changeover

Only applicable for EHBX and EHVX. The end-user sets the desired operation mode on the user interface: Heating, Cooling or Automatic (see also operation manual/user reference guide). When

Automatic is selected, the changing of the operation mode is based on:

Q Monthly allowance for heating and/or cooling: the end-user

indicates on a monthly base which operation is allowed (# [7:5]): both heating/cooling or heating only or cooling only. If the allowed operation mode changes to cooling only, the operation mode changes to cooling. If the allowed operation mode changes to heating only, the operation mode changes to heating.

Q Averaged outdoor temperature: the operation mode will be

changed in order to always be within range determined by the space heating OFF temperature for heating and the space cooling On temperature for cooling. If the outdoor temperature drops, the operation mode switches to heating and vice versa. Note that the outdoor temperature will be time-averaged (see

"8 Configuration" on page 30). When the outdoor temperature is between the space cooling On and the space heating OFF temperature, the operation mode remains

unchanged unless the system is configured in room thermostat control with one leaving water temperature zone and quick heat emitters. In that case, the operation mode will change based on:

Q Measured indoor temperature: besides the heating and the

cooling desired room temperature, the installer sets a hysteresis

value (e.g. when in heating, this value is related to the desired

cooling temperature) and an offset value (e.g. when in heating,

this value is related to the desired heating temperature).

Example: the desired room temperature in heating is 22°C and

in cooling 24°C, with a hysteresis value of 1°C and an offset of

4°C. Changeover from heating to cooling will occur when the

room temperature raises above the maximum of the desired

cooling temperature added by the hysteresis value (thus 25°C)

and the desired heating temperature added by the offset value

(thus 26°C). Oppositely, changeover from cooling to heating will

occur when the room temperature drops below the minimum of

the desired heating temperature subtracted by the hysteresis

value (thus 21°C) and the desired cooling temperature

subtracted by the offset value (thus 20°C).

9.3 Air purge function

When commissioning and installing the unit, it is very important to remove all air in the water circuit. When the air purge function is running, the pump operates without actual operation of the unit and the remove of air in the water circuit will start. There are 2 modes to purge air:

Q Manually: the unit will operate with a fixed pump speed and in a

fixed or custom position of the 3-way valve. The custom position of the 3-way valve is a helpful feature to remove all air from the water circuit in space heating or domestic hot water heating mode. The operation speed of the pump (slow or quick) can also be set.

Q Automatic: the unit change automatically the pump speed and

the position of the 3-way valve between space heating or domestic hot water heating mode.

The air purge function stops automatically after 30 minutes.

INFORMATION

It is recommended to start the air purge function in manually mode. When almost all air is removed, it is recommended to start the automatic mode. If necessary, repeat the automatic mode until you are sure that all air is removed from the system.

PULL DOWN AREA

*RLQ units include special equipment (insulation, heater sheet, ...) to ensure good operation in areas where low ambient temperature can occur together with high humidity conditions. In such conditions the *RHQ models may experience problems with severe ice build up on the aircooled coil. In case such conditions ara expected, the *RLQ must be installed instead. These models contain countermeasures (insulation, heater sheet, ...) to prevent freeze up.
