- Heating circuit pump control with connected remote
control FE7 / FEK
In conjunction with the FE7 or FEK remote control, in accordance
with the switching condition
ϕ
ACTUAL room
>ϕ
SET room
+ 1K
the respective heating circuit pump is switched off and the mixer
moves to CLOSE. This only applies if the room sensor influence is
set to K > 0. Reverse switching is subject to the following condition:
ϕ
ACTUAL room
>ϕ
SET room
The summer mode also becomes effective for the respective heat-
ing circuit when operating with a FE7 or FEK remote control.
Electric booster heater
Lower app limit HTG
Heat pump application limit
The heat pump is switched off if the outside temperature drops
below the selected lower application limit for heating.
The electric emergency/booster heater alone provides central
heating.
Dual mode temp HEATING
The dual mode temperature of the heat pump for heating oper-
ation
Below this outside temperature, the electric emergency/booster
heater is switched on for heating operation, subject to load.
5.4.3 DHW
DHW temperatures
COMFORT TEMPERATURE and ECO TEMPERATURE
Here you can select the set DHW temperatures for Comfort and
ECO mode.
Standard settings
DHW hysteresis
This determines the switching hysteresis for DHW operation.
- Starting DHW heating at the set DHW temperature minus the
hysteresis value.
DHW learning function
Setting OFF
When heating DHW, the system automatically adjusts itself to the
required DHW temperature (self-learning function).
The electric emergency/booster heater will be added as a booster
stage as soon as the heat pump is shut down in DHW mode via
the HP sensor or via the hot gas temperature limit (130 °C). If the
flow temperature of 70°C is achieved in this operating mode,
DHW heating will be terminated, and the set DHW temperature is
overwritten with the actual DHW temperature.
Setting ON
As soon as the heat pump is shut down in DHW mode via the HP
sensor or the hot gas temperature limit (130 °C), DHW heating is
terminated and the set DHW temperature will be overwritten with
the current actual DHW temperature. This operating mode saves
energy, as DHW is exclusively heated by heat pump.
DHW correction
The DHW temperature is measured in the bottom third of the
cylinder. The DHW outlet temperature is approx.3K higher than
the measured temperature. This deviation is corrected and can be
calibrated if necessary.
Combi cylinder
As soon as the parameter is set to ON, the heating circuit pumps
are switched off during DHW heating.
(Only in conjunction with the instantaneous water cylinder SBS)
Pasteurisation
The DHW cylinder is heated daily at 01:00 h to 60 °C if pasteurisa-
tion has been enabled. Pasteurisation only takes place when the
emergency/booster heater is connected.
Electric booster heater
Dual mode temp DHW
The dual mode temperature of the heat pump for DHW heating.
Below this outside temperature, the electric emergency/booster
heater is switched on for DHW heating, subject to load.
Lower app limit DHW
Lower application limit for the heat pump for DHW heating.
The heat pump is switched off at outside temperatures below the
selected lower DHW application limit.
The electric emergency/booster heater alone provides DHW heat-
ing.
