Room thermostat control - Using the leaving water temperature home pages
INFORMATION
The leaving water is the water that is sent to the heat emitters. The desired leaving water temperature is set by your installer in accordance with the heat emitter type.
Example: Underfloor heating is designed for lower leaving water temperature than radiators and heat pump convectors and/or fan coil units. You only have to adjust leaving water temperature settings in case of problems.

About domestic hot water control
Depending on the DHW tank mode (installer setting), you use a different domestic hot water control:
▪ Reheat mode
▪ Scheduled mode
▪ Scheduled + reheat mode

Daikin Altherma ground source heat pump
4P351749-1C – 2015.10
CAUTION
The backup heater permission schedule is used to restrict or allow backup heater operation based on a weekly program. Advice: In order to avoid unsuccessful disinfection function, at least allow the backup heater (by the weekly program) for minimum 4 hours starting from the scheduled start-up of disinfection. If the backup heater is restricted during disinfection, this function will NOT be successful and the applicable warning AH will be generated.
INFORMATION
In case of error code AH and no interruption of the disinfection function occurred due to domestic hot water tapping, following actions are recommended:
▪ When the Domestic hot water > Type > Reheat or
Reheat + sched. is selected, it is recommended to program the start-up of the disinfection function at least
4 hours later than the last expected large hot water tapping. This start-up can be set by installer settings
(disinfection function).
▪ When the Domestic hot water > Type > Scheduled only is selected, it is recommended to program a Storage eco 3 hours before the scheduled start-up of the disinfection function to preheat the tank.
To determine which DHW tank mode you are using (method 1)
Check the installer settings table filled in by the installer.
To determine which DHW tank mode you are using (method 2)
Prerequisite: User profile = Detailed.

▪ At 00:00 the DHW tank is programmed to heat up the water to a preset value (example: Storage comfort = 60°C).
▪ During the morning, you consume hot water and the DHW tank temperature decreases.
▪ At 14:00 the DHW tank is programmed to heat up the water to a preset value (example: Storage eco = 50°C). Hot water is available again.
▪ During the afternoon and evening, you consume hot water again and the DHW tank temperature decreases again.
▪ At 00:00 the next day, the cycle repeats.

4.5.4
Scheduled + reheat mode
In scheduled + reheat mode ( ), the domestic hot water control is the same as in scheduled mode. However, when the DHW tank temperature drops below a preset value (=reheat tank temperature – hysteresis value; example: 35°C), the DHW tank heats up until it reaches the reheat set point (example: 45°C). This ensures that a minimum amount of hot water is available at all times.

Weather dependent operation
In space heating control, the leaving water temperature setpoint mode can be:
▪ Fixed
▪ Weather-dependent (the leaving water temperature is determined automatically depending on the outdoor temperature)
To select the setpoint mode, see the installer reference guide.
To set the parameters for the weather-dependent curve, see below.

INFORMATION
Auto emergency: By default, backup heater operation during emergency operation is NOT allowed. This means that when a heat pump failure occurs the user needs to manually confirm that backup heater may operate during emergency. If the house is unattended for longer periods, we recommend that setting [A.5.1.2] Emergency shall be set to Automatic.

5 Energy saving tips
Tips about room temperature
▪ Make sure the desired room temperature is NEVER too high, but
ALWAYS according to your actual needs. Each saved degree can save up to 6% of heating costs.
▪ Do NOT increase the desired room temperature to speed up space heating. The space will NOT heat up faster.
▪ When your system layout contains slow heat emitters (example: under floor heating), avoid large fluctuation of the desired room temperature and do NOT let the room temperature drop too low. It will take more time and energy to heat up the room again.
▪ Use a weekly schedule for your normal space heating needs. If necessary, you can easily deviate from the schedule:
▪ For shorter periods: You can overrule the scheduled room temperature. Example: When you have a party, or when you are leaving for a couple of hours.
▪ For longer periods: You can use the holiday mode. Example:
When you stay at home during your holiday, or when you go away during your holiday.
Tips about leaving water temperature
▪ In heating mode, a lower desired leaving water temperature results in lower energy consumption and better performance.
▪ Set the desired leaving water temperature in accordance with the heat emitter type. Example: Underfloor heating is designed for lower leaving water temperature than radiators and heat pump convectors.
Tips about DHW tank temperature
▪ Use a weekly schedule for your normal domestic hot water needs
(only in scheduled mode).
▪ Program to heat up the DHW tank to a preset value (Storage comfort = higher DHW tank temperature) during the night, because then space heating demand is lower.
▪ If heating up the DHW tank once at night is not sufficient, program to additionally heat up the DHW tank to a preset value
(Storage eco = lower DHW tank temperature) during the day.
▪ Make sure the desired DHW tank temperature is NOT too high.
Example: After installation, lower the DHW tank temperature daily by 1°C and check if you still have enough hot water.
▪ Program to turn ON the domestic hot water pump only during periods of the day when instant hot water is necessary. Example:
In the morning and evening.

6 Maintenance and service
6.1
Overview: Maintenance and service
The installer has to perform a yearly maintenance. You can find the contact/helpdesk number via the user interface.
As end user, you have to:
▪ Keep the area around the unit clean.
▪ Keep the user interface clean with a soft damp cloth. Do NOT use any detergents.
▪ Regularly check if the water pressure indicated on the manometer is above 1 bar.
Refrigerant
This product contains fluorinated greenhouse gases. Do NOT vent gases into the atmosphere.
Refrigerant type: R410A
Global warming potential value: 2087.5
Periodical inspections for refrigerant leaks may be required depending on the applicable legislation. Please contact your installer for more information.
6.2

6 Maintenance and service
7.4
Symptom: You are feeling too cold
(hot) in your living room
Possible cause
The desired room temperature is too low (high).
Corrective action
Increase (decrease) the desired room temperature.
The desired room temperature cannot be reached.
If the problem recurs daily, do one of the following:
▪ Increase (decrease) the room temperature preset value.
▪ Adjust the room temperature schedule.
Increase the desired leaving water temperature in accordance with the heat emitter type.
7.5
Symptom: The water at the tap is too cold
Possible cause
You ran out of domestic hot water because of unusual high consumption.
The desired DHW tank temperature is too low.
Corrective action
If you immediately need domestic hot water, activate the DHW tank booster mode. However, this consumes extra energy.
If you can wait, overrule
(increase) the active or next scheduled desired temperature so that more hot water will be produced exceptionally.
If the problems recurs daily, do one of the following:
▪ Increase the DHW tank temperature preset value.
▪ Adjust the DHW tank temperature schedule.
Example:
Program to additionally heat up the
DHW tank to a preset value
(Storage eco = lower tank temperature) during the day.
7.6
Symptom: Heat pump failure
When the heat pump fails to operate the backup heater can serve as an emergency heater and either automatically or non-automatically take over the heat load. When auto emergency is activated and a heat pump failure occurs, the backup heater will automatically take over the heat load. When a heat pump failure occurs and auto emergency is not activated, the domestic hot water and space heating operations will stop and need to be recovered manually. The user interface will then ask you to confirm whether the backup heater can take over the heat load or not. When the heat pump fails, will appear on the user interface.
