Datasheet

NC / NO
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.
> NC / NO or NO / NO in one unit
> Separate adjustable temperatures
> Color coded temperature dials
> DIN rail mountable

¹ When connecting with stranded wires, wire end ferrules must be used.
Important note: The contact system of the regulator is subjected to environmental influences, thus the contact resistance
may change. This can lead to a voltage drop and/or self-heating of the contacts.
² For regulating heat exchangers and fans (e. g. LE 019) and as an alarm contact for monitoring the interior temperature of electronic enclosures.
