Dual Thermostat ZR 011
- Two thermostats in one unit
- one Normally Closed (NC) & one Normally Open (NO)
- or two Normally Open (NO)
- Each with wide adjustable temperature range
- Available with °F or °C scale
- DIN rail mountable
The ZR 011 houses two separate thermostats, allowing the independent control of heating and cooling or other equipment. Both thermostats offer wide adjustment ranges and are color coded for easy function recognition.
