The ZR 011 dual thermostat is a plastic, IP20-rated device with separate normally closed and normally open snap-action contacts for independent heating and cooling control. It mounts on a 35 mm DIN rail and measures 2.6 in high, 2.0 in wide, and 1.8 in deep, weighing 3.2 oz. The 01176.0-00 variant has a switching range of 32 °F to 140 °F for both contacts, with a switching differential of 7 K and tolerance of ±4 K. It handles 10 A at 250 VAC for the NC contact and 15 A at 120 VAC for the NO contact, with a DC switching capacity of 30 W at 24-72 V. Connections support up to 2.5 mm² rigid or 1.5 mm² stranded wire, and it operates between -49 °F and 176 °F. The device is CSA approved and carries CCC and CQC certifications.
The ZR 011 houses two separate thermostats, allowing the independent control of heating and cooling or other equipment.
Thermostat NC (normally closed):
Thermostat opens at temperature rise - for regulating heaters or for switching signal devices. Comes with red temperature dial.
Thermostat NO (normally open):
Thermostat closes at temperature rise - for regulating filter fans and heat exchangers or for switching signal devices. Comes with blue temperature dial.
