Overshoot
Restriction: This function is only applicable in heating mode.
This function defines how much the water temperature may rise above the desired
leaving water temperature before the compressor stops. The compressor will start
up again when the leaving water temperature drops below the desired leaving
water temperature.
# Code Description
[4.B] [9-04] Overshoot:
▪ 1°C~4°C
Antifrost
Room frost protection [1.4] prevents the room from getting too cold. For more
information about room frost protection, see "10.5.2Room"[4106].
10.5.6 Tank
Comfort setpoint
Only applicable when domestic hot water preparation is Schedule only or
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.
# Code Description
[5.2] [6-0A] Comfort setpoint:
▪ 30°C~[6‑0E]°C
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 Description
[5.3] [6-0B] Eco setpoint:
▪ 30°C~min(50,[6‑0E])°C
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.
