HC FUNCTION
(heating circuit function selection)
If this parameter is modified the controller is restarted.
"RESET" briefly appears in the display.
00 => Standard heating circuit
01 => Control to fixed flow temperatures
During the heating periods (see heating program ) the
heating circuit is operated with a fixed preset flow
temperature
[T-FLOW-DAY], and during reduced mode operation with a
fixed preset flow temperature [T-FLOW REDUC]
accordingly.
02 => Swimming pool control (only for heating circuit II)
This function can be used to heat a swimming pool. The
mixer controls the flow temperature for the swimming pool
heat exchanger. The swimming pool water temperature
sensor is connected to the room sensor connection for the
heating circuit (see FBR).
[Plug III; 1+2]
The flow temperature control operates like normal room
control [ROOM INFL].
The set value for the water temperature can be entered in
the user area of the associated heating circuit level
[T-POOL 1/2/3]. The heating program operates. No
heating takes place during the reduction period (frost
protection only).
The water temperature and the current set value are
displayed in the display level [T-POOL/T-POOL DES].
03 => Hot water circuit
This function can be used to operate additional hot water
circuits. The heating circuit flow sensor is located in the hot
water storage tank.
The hot water temperature set value can be entered in the
user area of the associated heating circuit level [T-DHW
1/2/3]. The heating program for the heating circuit acts as
an enable program for the storage tank. The storage tank
set value is set to 10°C during the reduction period.
The boiler controller hot water priority function can be used
(partial priority acts like priority).
