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!
10.4 Tmax S2
menu 5.x
= switch-off temperature at sensor 2
If this value is exceeded at sensor 2 and the other conditions are also met,
then the controller switches the associated pump and/or valve off. If sensor
2 falls below this value again and the other conditions are also met, then
the controller switches the pump and/or valve on again.
Setting range: from 0°C to 99°C/default setting: 60°C

10.5 Tmax S3
menu 5.x
= switch-off temperature at sensor 3
If this value is exceeded at sensor 3 and the other conditions are also met,
then the controller switches the associated pump and/or valve off. If sensor
3 falls below this value again and the other conditions are also met, then
the controller switches the pump and/or valve on again.
Setting range: from 0°C to 99°C/default setting: 60°C

∆
T R1
menu 5.x
= switch-on temperature difference for relay R1
If this temperature difference between the reference sensors is exceeded
and the other conditions are also met, then the controller switches the
pump on. If the temperature difference drops to 1/3 of this value, then the
pump is switched off again.
Setting range: from 4°C to 20°C/default setting: 10°C
Caution
If the set temperature difference is too small, this may result
in ineffective operation, depending on the system and sensor
positions. Special switching conditions apply for speed control
(see 12.9)!
