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.
Thermostat (NC): Thermostat opens on temperature rise – for regulating heaters or for switching signal devices.
Comes with red temperature dial.
Thermostat (NO): Thermostat closes on temperature rise – for regulating filter fans and heat exchangers or for
switching signal devices. Comes with blue temperature dial.
