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. Two thermostats in one casing: Thermostat (contact breaker, normally closed) for regulating heaters. The contact opens when temperature is rising. Thermostat (contact maker, normally open) for regulating filter fans and heat exchangers or switching signal devices when temperature limit has been exceeded. The contact closes when temperature is rising. Heaters and cooling equipment can be switched independently from each other with a temperature offset as opposed to the usual change-over contacts. > NO and NC in one casing > Separate adjustable temperatures > High switching capacity > Terminals easily accessible > Clip fixing Thermostat ZR 011 (NC/NO) Connection diagram Thermostat ZR 011 Filter fan Example of connection Heater Heater Filter fan, Cooling equipment, Signal device DUAL THERMOSTAT ZR 011 Art.
