ZR 011
Winston
Features
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.
