Settings Heating circuit
Caution
The additional heating (relais R5) is started when the flow temperature
(in case of 2 heat circuits: one of the flow temperatures)is below the refe
-
rence flow temperature for 5 minutes continously.
Switch on hysteresis for additional heating
This setting determines the allowed undershoot of the heat circuit temperature under
the calculated reference flow temperature. If the heat circuit flow temperature falls below
the reference temperature by this value, the additional heating (R5) is activated after a
delay of 5 minutes.
Settings range: -10°C to 10°C / Default: -2°C

Caution
If sensor 4 is not connected, the additional heating at R5 is switched off
when the sensor of the heat circuit S2 (respectively, of the heat circuits S2
and S3) reaches or exceeds the reference flow temperature.
Caution
It is recommended to install sensor 4 in the buffer at the same level (or
below) of the heat circuit conduit to prevent unnecessary switching of the
additional heating.
Switch off hysteresis (only if S4 is connected)
This settings determines the allowed overstepping of the heat circuit temperature to the
calculated reference flow temperature at sensor 4. If the temperature at S4 exceeds the
reference flow temperature by this value, the additional heating (R5) is switched off.
Settings range: 1°C to 10°C / Default: 2°C
