Setting range: 0 to 80ºC / 32 to 176ºF
Switching differential
Immersion thermostat:
Contact thermostat:
Electro-mechanical limit aquastat, according to the liquid
expansion principle, switches the heating circuit pump
OFF, when the set value has been exceeded.
In such cases the supply temperature reduces only
slowly, e.g. it may be several hours before the system
restarts again automatically.
