If the temperature at sensor 3 drops below this value and the period of the
thermostat function is enabled, the corresponding relais for additional heating
is switched on. Additional heating remains active until the temperature at
sensor 3 reached Tsetpoint S3 + hysteresis.
Setting range: from 0°C to 99°C/default setting: 60°C

Danger!
Temperature values which are set too high can lead to scalding
or damage to the system. Scalding protection must be provided
by the customer!

= Switch-on/-off temperature at relais R2
If this temperature difference between the reference sensors is exceeded
and the other conditions are also met, then the controller switches the
pump and/or the valve on. If the temperature difference drops to
∆
T R2
Off, then the pump and/or the valve is switched off again.

Setting the temperature difference too small may lead to ineffective op-
eration of the system and to frequent switching of the pump, depending
on the system and sensor positions.
10.8 Hysteresis S3
menu 5.x
= Hysteresis for thermostat function at sensor 3
If Tsetpoint S3 is exceeded by the set hysteresis, additional heating at the
corresponding relais is switched off. In Energy savings mode heating is
active till hystereis is reached.
Settings range: 0°C to 20°C / Default: 10°C
