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.
Comfort setpoint
Only applicable when domestic hot water preparation is Schedule
Schedule + reheat. When programming the schedule, you can make use of
the comfort setpoint as a preset value. When you later want to change the storage
setpoint, you only have to do it in one place.
The tank will heat up until the storage comfort temperature has been reached. It
is the higher desired temperature when a storage comfort action is scheduled.
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.

Eco setpoint
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).
# Code
[5.3] [6-0B]
Reheat setpoint
Desired reheat tank temperature, used:
▪ in Schedule + reheat mode, during reheat mode: the guaranteed minimum
tank temperature is set by the Reheat setpoint minus the reheat hysteresis.
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 rises above this value, domestic hot water preparation and
space heating/cooling are executed sequentially.

[5.4] [6-0C]
Schedule
You can set the tank temperature schedule using the schedule screen. For more
information about this screen, see
Heat up mode
The domestic hot water can be prepared in 3 different ways. They differ from each
other by the way the desired tank temperature is set and how the unit acts upon it.
