Tamper-proof dual thermostat

FTD 011

Fixed thermostat contact breaker (NC) and thermostat normally open contact (NO) in one casing. Unlike thermostats with change-over contact, the double thermostat switches independently. This allows heating and cooling devices to be switched in different temperature ranges.

Contact breaker (NC, normally closed, heating) and normally open contact (NO, normally closed, cooling) in one casing
Jump contact enables independent switching
Fixed temperature setting
High switching accuracy
Clip fixing
