ZR 011 Intelligent Dual Thermostat 

1.Features:

NO/NC in one casing

Separate adjustable temperatureHigh switching capacityTerminals 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.
