The ZR 011 is a dual thermostat with independently adjustable normally closed and normally open contacts for separate heating and cooling control. It uses a snap-action bimetal sensor and clip mounting for 35 mm DIN rail. The housing is plastic, UL94 V-0 compliant, and rated IP20. It operates from -49 °F to 176 °F with a switching differential of 7 K ±4 K. The NC contact switches 10 A at 250 VAC, the NO contact 15 A at 120 VAC, and both support 1 A at 30 VDC DC. Minimum switching capacity is 0.48 W. Connections accept 2.5 mm² rigid or 1.5 mm² stranded wire. It measures 2.6 in × 2 in × 1.8 in and weighs 3.2 oz. CCC and CQC certifications apply.
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.
