ZR 011 Dual Thermostat
- NC / NO or NO / NO in one unit
- Separate adjustable temperatures
- Color coded temperature dials
- DIN rail mountable
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.
