Setting the space operation mode
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 space operation modes
The heat pump is a heating only model. The system can heat up a
space, but NOT cool down a space.

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.

▪ Keep the user interface clean with a soft damp cloth. Do NOT use
any detergents.

Formula to calculate the greenhouse gas emissions:
GWP value of the refrigerant × Total refrigerant charge [in

If the problems recurs daily, do
one of the following:

Symptom: Heat pump failure
When the heat pump fails to operate, the backup heater can serve

▪ When auto emergency is activated and a heat pump failure
occurs, the backup heater will automatically take over the heat
load.
▪ 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 can take over
the heat load or not.
