3.5 Domestic hot water control
3.5.1 Reheat mode
In reheat mode the DHW tank continuously heats up to the temperature shown on the home screen (example: 50°C) when the temperature drops below a certain value.

INFORMATION
Risk of space heating capacity shortage for domestic hot water tank without internal booster heater: In case of frequent domestic hot water operation, frequent and long
space heating/cooling interruption will happen when selecting the following: Tank > Heat up mode > Reheat only.
INFORMATION
When the DHW tank mode is reheat, the risk for capacity shortage and comfort problem is significant. In case of frequent reheat operation, space heating/cooling function is regularly interrupted.

3.5.2 Scheduled mode
In scheduled mode the DHW tank produces hot water corresponding to a schedule. The best time to allow the tank to produce hot water is at night, because the space heating demand is lower.

Example:

Initially, the DHW tank temperature is the same as the temperature of the domestic water entering the DHW tank (example: 15°C).
At 00:00 the DHW tank is programmed to heat up the water to a preset value (example: 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: 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.

3.5.3 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.
Example:

3.5.4 Using DHW powerful operation
About powerful operation
Powerful operation allows the domestic hot water to be heated by the backup heater or booster heater. Use this mode on days when there is more hot water usage than usual.
To check if powerful operation is active If is displayed on the home screen, powerful operation is active.
Activate or deactivate Powerful operation as follows:

1| Go to [5.1]: Tank > Powerful operation|
---|---|---
2| Turn powerful operation Off or On.|

Usage example: You immediately need more hot water You are in the following situation:

You already consumed most of your domestic hot water.
You cannot wait for the next scheduled action to heat up the domestic hot water tank.
Then you can activate powerful operation. The domestic hot water tank will start heating up the water to the Comfort temperature.

INFORMATION
When powerful operation is active, the risk of space heating/cooling and capacity shortage comfort problems is significant. In case of frequent domestic hot water operation, frequent and long space heating/cooling interruptions will happen.

Energy saving tips

Tips about room temperature

Make sure the desired room temperature is NEVER too high (in heating mode) or too low (in cooling mode), but ALWAYS according to your actual needs. Each saved degree can save up to 6% of heating/cooling costs.
Do NOT increase/decrease the desired room temperature to speed up space heating/cooling. The space will NOT heat up/cool down faster.
When your system layout contains slow heat emitters (example: underfloor heating), avoid large fluctuation of the desired room temperature and do NOT let the room temperature drop too low/ rise too high. It will take more time and energy to heat up/cool down the room again.
Use a weekly schedule for your normal space heating or cooling needs. If necessary, you can easily deviate from the schedule:
For shorter periods: You can overrule the scheduled room temperature until the next scheduled action. 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.

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 (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 (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.

6.2 Symptom: You are feeling too cold (hot) in your living room

Possible cause	Corrective action
The desired room temperature is too low (high).	Increase (decrease) the

desired room temperature. See “To change the desired room temperature” 4[ 7].
| If the problem recurs daily, do one of the following:
| ▪ Increase (decrease) the room temperature preset value. See the user reference guide.
| ▪ Adjust the room temperature schedule. See “3.7 Schedule screen: Example” 4[ 9].
The desired room temperature cannot be reached.| Increase the desired leaving water temperature in accordance with the heat emitter type. See “To change the desired leaving water temperature” 4[ 7].
The weather-dependent curve is set incorrectly.| Adjust the weather-dependent curve. See the user reference guide.

6.3 Symptom: The water at the tap is too cold

Possible cause	Corrective action
You ran out of domestic hot water because of unusual high consumption.	If you

immediately need domestic hot water, activate the DHW tank Powerful operation. However, this consumes extra energy. See “Using DHW powerful

operation” 4[ 8].

The desired DHW tank temperature is too low.
| If the problems recurs daily, do one of the following:
| ▪ Increase the DHW tank temperature preset value. See the user reference guide.
| ▪ Adjust the DHW tank temperature schedule. Example: Program to additionally heat up the DHW tank to a preset value (Eco setpoint = lower tank temperature) during the day. See “3.7 Schedule screen: Example” 4[ 9].

6.4 Symptom: Heat pump failure
When the heat pump fails to operate, the backup heater and/or booster heater can serve as an emergency heater and either automatically or non-automatically take over the heat load.

When auto emergency is set to Automatic and a heat pump failure occurs:
For EHVH/X: The backup heater will automatically take over the heat load and domestic hot water production
For EHBH/X: The backup heater will automatically take over the heat load, and the booster heater in the optional tank will automatically take over the domestic hot water production.
When auto emergency is set to Manual and a heat pump failure occurs, the domestic hot water and space heating operation will stop and need to be recovered manually via the user interface. To recover operation manually, go to the Malfunctioning main menu screen, where the user interface will then ask you to confirm whether the backup heater and/or booster heater can take over the heat load not. When the heat pump fails, or will appear on the user interface.

Possible cause	Corrective action
Heat pump is damaged.	See “6.1 To display the help text

in case of a malfunction ****” [4 14].

INFORMATION
When the backup heater or booster heater takes over the heat load, electricity consumption will be considerably higher.

6.5 Symptom: The system is making gurgling noises after commissioning

Possible cause	Corrective action
There is air in the system.	Purge air from the system. (a)
Various malfunctions.	Check if is displayed on the home screen of the user

interface. See “6.1 To display the help text in case of a malfunction” ****[4 14] for more
information about the malfunction.

(a) We recommend to purge air with the air purge function of the unit (to be performed by the installer). If you purge air from the heat emitters or collectors, mind the following:

WARNING
Air purging heat emitters or collectors. Before you purge air from heat emitters or collectors, check if or ****is displayed on the home screen of the user interface.

If not, you can purge air immediately.
If yes, make sure that the room where you want to purge air is sufficiently ventilated. Reason: Refrigerant might leak into the water circuit, and subsequently into the room when you purge air from the heat emitters or collectors.

Disposal

NOTICE
Do NOT try to dismantle the system yourself: dismantling of the system, treatment of the refrigerant, oil and other parts MUST comply with applicable legislation. Units MUST be treated at a specialised treatment facility for reuse, recycling and recovery.
