Heating a real estate and domestic hot water
Controller has two heating circuits (H1 and H2). The lower part of
the heating boiler is warmed up with compressor and, if needed,
with the electrical heating resistor (S1) so that enough heat is provi-
ded to the heating system according to the current need. The upper
part of theboiler is heated by a compressor and, if necessary, by me-
ans of an electric heater S1, so that hot domestic water is obtained.
Getting ready for excessive consumption of hot domestic water:
When it is expected to have higher hot domestic water consumption
than normal, heating can be boosted with additional warming. This
is activated by pressing the separate switch.

sor and
El.heater
You can choose whether the ground heating is controlled by a com-
pressor only or by an electric heater only, or whether an electric
heater is used with the compressor.
Boiler Top winter
65
30... 75 °C
Setting value of the Boiler Top when the outdoor temp. is < -20°C.
Boiler Top summer
55
30... 75 °C
Setting value of the Boiler Top when the outdoor temp. is > +20°C.
Hot water hysteresis
5°C
3...10°C
Hysteresis of the top part of the heating boiler control
Boiler Down hysteresis
5 °C
3...7 °C
Hysteresis of the down part of the heating boiler control.
Boiler Down MIN limit
30
30...55°C
Minimum temperature of the lower part of theboiler.
Compressor Stop
55°C
45...55°C
When the temperature of the lower part of the boiler (meas. 10) is
exceeded this setpoint always stops the compressor, even if the top
of the boiler commands the compressor to start.
Boiler Top hysteresis heating
resistor
3 °C
0...10°C
The electric heater starts when the temperature at the top of the
boiler drops amount of [”Hot water hysteresis” + ”Boiler Top hystere-
sis heating resistor”] below the calculated “Boiler top setting” value.
El. Heat start up delay
30
0 ... 120 min.
The temperature of the middle part of the boiler (measurement 11) is
able to switch the electrical heating resistor on only when the com-
pressor has been running the time (minutes) set here.
Extra heating
Extra heating time

40...55°C
0... 6h
When the “Extra heating” button is pressed, the minimum tempe-
rature setpoint (Boiler Down MIN limit) at the bottom of the boiler
changes to the “Extra heating” setpoint (eg 45 ° C) for the duration
of the “Extra heating time” setpoint. This operation also makes the
lower part of the DHW boiler hotter, which increases the hot water
capacity.
Dividing ventil pre-open
40%
25...100%
Pre-opening degree of the Dividing Valve. The pre-opening is per-
formed before the electric heater is switched on
Dividing ventil close prevent
60s
30...240s
Closing prevent time of the DV after pre-opening. The time calcula-
tion starts when the electric heater is switching ON.
Boiler Top setting
Calculated
Boiler Top setting is determined according to the ”Boiler Top summer
”and ”Boiler Top winter ” setting (see figure).

You can check what asks for or prevents the compressor and / or electric heater from turning
on. Start and stop delays are also displayed. In addition, the running time / on of the compres-
sor and the electric heater is displayed.
