Dual Thermostat ZR 011
- NO and NC in one casing
- Separate adjustable temperatures
- High switching capacity
- Terminals easily accessible
- Clip fixing
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.
