Two thermostats in one casing:
Thermostat (contact breaker, normally closed) for regulating heaters
Thermostat (contact maker, normally open) for regulating filter fans
and heat exchangers or switching signal devices when temperature
limit has been exceeded.
Heaters and cooling equipment can be switched independently from
each other with a temperature offset as opposed to the usual
change-over contacts.

Switch temperature difference: 7K (sign 4K tolerance)
Sensor element: thermostatic bimetal
Contact type: snap-action contact
Contact resistance: < 10mOhm
