Pump outside range
When the pump operation function is disabled the pump will stop if
the outdoor temperature is higher than the value set by the
Space
heating off temperature [4‑02]. When the pump operation is
enabled, the pump operation is possible at all outdoor temperatures.
# Code Description
[4.9] [F-00] Pump operation:
▪ 0: Disabled if outdoor temperature is
higher than [4‑02].
▪ 1: Possible at all outdoor
temperatures.
Overshoot
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.
This function is ONLY applicable in heating mode.
# 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
"8.4.2 Room" on page 50 .
8.4.6 Tank
Tank setpoint screen
You can set the domestic hot water temperature using the setpoint
screen. For more information about how to do this, see
"8.3.5 Setpoint screen" on page 47 .
Powerful operation
You can use powerful operation to immediately start heating up the
water to the preset value (Storage comfort). However, this consumes
extra energy. If powerful operation is active, will be shown on
the home screen.
To activate powerful operation
Activate or deactivate Powerful operation as follows:
1 Go to [5.1]:
Tank
>
Powerful operation
2 Turn powerful operation Off or On .
Usage example: You immediately need more hot water
If you are in the following situation:
▪ You already consumed most of your hot water.
▪ You cannot wait for the next scheduled action to heat up the DHW
tank.
Then you can activate DHW powerful operation.
Advantage: The DHW tank immediately starts heating up the water
to the preset value (Storage comfort).
INFORMATION
When powerful operation is active, the risk of space
heating and capacity shortage comfort problems is
significant. In case of frequent domestic hot water
operation, frequent and long space heating interruptions
will happen.
Comfort setpoint
Only applicable when domestic hot water preparation is Schedule
only or Sc 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.
