Operation range
Depending on the average outdoor temperature, the operation of the
unit in space heating is prohibited.
Space heating OFF temp: When the averaged outdoor temperature
raises above this value, space heating is turned OFF to avoid
overheating.

Domestic hot water control: advanced
Preset tank temperatures
Only applicable when domestic hot water preparation is scheduled
or sch reheat.
You can define preset tank temperatures:
▪ storage economic
▪ storage comfort
▪ reheat
Preset values make it easy to use the same value in the schedule. If
you later want to change the value, you only have to do it in 1 place
(see also operation manual and/or user reference guide).
Storage comfort: When programming the schedule, you can make
use of the tank temperatures set as preset values. The tank will then
heat up until these setpoint temperatures have been reached.
Additionally, a storage stop can be programmed. This feature puts a
stop to tank heating even if the setpoint has NOT been reached.
Only program a storage stop when tank heating is absolutely
undesirable.

Storage eco: The storage economic temperature denotes the lower
desired tank temperature. It is the desired temperature when a
storage economic action is scheduled (preferably during day).

Reheat: The desired reheat tank temperature is used:
▪ in reheat mode or scheduled + reheat mode, as guaranteed
minimum tank temperature: if the tank temperature drops below
this value, the tank is heated up.
▪ during storage comfort, to prioritize the domestic hot water
preparation. When the tank temperature raises above this value,
domestic hot water preparation and space heating are executed
sequentially.

Weather dependent
The weather dependent installer settings define the parameters for
the weather dependent operation of the unit. When weather
dependent operation is active the desired tank temperature is
determined automatically depending on the averaged outdoor
temperature: low outdoor temperatures will result in higher desired
tank temperatures as the cold water tap is colder and vice versa. In
case of scheduled or screheat domestic hot water
preparation, the storage comfort temperature is weather dependent
(according to the weather dependent curve), the storage economic
and reheat temperature are NOT weather dependent. In case of
reheat only domestic hot water preparation, the desired tank
temperature is weather dependent (according to the weather
dependent curve). During weather dependent operation, the end
user cannot adjust the desired tank temperature on the user
interface.
