value (Comfort (heating)) = 20°C.
After 2hours, the schedule will
be used again (17:20 => 20°C).
Before you have changed the
mode from scheduled to preset
value, and now you temporarily
overrule the preset value.
Desired temperature = custom
temperature = 21°C.
After 2hours, the schedule will
be used again (17:20 => 20°C).
▪ You are using the following room temperature schedule:

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.

4.5.1 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
CAUTION
The booster heater permission schedule is used to restrict
or allow booster heater operation based on a weekly
program. Advice: In order to avoid unsuccessful
disinfection function, at least allow the booster heater (by
the weekly program) for minimum 4hours starting from the
scheduled start-up of disinfection. If the booster 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.
Only change this if the desired room
temperature cannot be reached.

INFORMATION
The values for High, Medium and Low correspond with the
electricity price values for High, Medium and Low
previously set. If no schedule is set, the electricity price for
High is taken into account.
5.4 About energy prices in case of an incentive per kWh renewable energy
An incentive can be taken into account when setting the energy
prices. Although the running cost can increase, the total operation
cost, taking into account the reimbursement will be optimized.
NOTICE
Make sure to modify the setting of the energy prices at the
end of the incentive period.
5.4.1 To set the fuel price in case of an incentive per kWh renewable energy
Prerequisite: Calculate the value for the fuel price with the following
formula: actual fuel price+(incentive/kWh×0.9)
1 Go to [7.4.6]: > User settings > Preset values > Fuel price.
2 Use and to set the correct price.
3 Press to confirm.
5.4.2 To set the electricity price in case of an incentive per kWh renewable energy
Prerequisite: Calculate the value for the electricity price with
following formula: actual electricity price+incentive/kWh.
1 Go to [7.4.5]: > User settings > Preset values > Elec price.
2 Use and to set the correct prices for High, Medium and
Low, according to your electricity tariff.
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 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 or cooling
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. In
cooling, the opposite is valid.
▪ 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.

7 Maintenance and service
Tips about DHWtank 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 DHWtank to a preset value
(Storage eco = lower DHWtank temperature) during the day.
▪ Make sure the desired DHWtank temperature is NOT too high.
Example: After installation, lower the DHWtank 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.
7 Maintenance and service
7.1 Overview: Maintenance and service
The installer has to perform a yearly maintenance. You can find the
contact/helpdesk number via the user interface.
As enduser, 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 1bar.

cannot be reached.
Increase (decrease) the desired
room temperature.
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.
WARNING
The refrigerant in the system is safe and normally does not
leak. If the refrigerant leaks in the room, contact with a fire
of a burner, a heater or a cooker may result in a harmful
gas.
Turn off any combustible heating devices, ventilate the

8.5 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.
The desired DHWtank
temperature is too low.
If you immediately need domestic
hot water, activate the DHWtank
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.
▪ When auto emergency is activated and a heat pump failure
occurs:
▪ The backup heater will automatically take over the heat load.
▪ The booster heater will automatically take over the domestic hot
water production.
▪ When auto emergency is not activated and a heat pump failure
occurs, 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 or booster
heater can take over the heat load or not.
When the heat pump fails, will appear on the user interface.
Possible cause Corrective action
Heat pump is damaged. ▪ Press to view a description
of the problem.
▪ Press again.
▪ Select to allow the backup
heater to take over the heat
load.
