¹ When connecting with 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.
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.
