Tamper-proof Dual thermostat - FTD 011
FTD
FTD 011 is two thermostats in the same casing. Available with one NO contact and one NC contact or with two NO contacts.
Â
Normally closed - Contact breaks (red casing) for regulating heaters or for switching signal devices when temperature has fallen below the minimum value. The contact opens when temperature is rising.
Â
Normally open - Â Contact makes(blue casing) for regulating filter fans, heat exchangers, cooling devices or for switching signal devices when temperature limit has been exceeded. The contact closes when temperaure is rising.
Â
The thermostat with one NO contact and one NC contact is used, for example, for controlling both a heater and fan.
Â
The thermostat has two NO contacts, good for controlling two fans. One of the thermostats activates first and a smaller fan, for example, is activated. If this fan is unable to cool sufficiently and the temperature thus increases, the other thermostat activates and a larger fan can be started.
Â
- NO and NC thermostats in one housing
