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.

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.
