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.

ANTI FROST ASSURANCE

The anti frost assurance is a symbol on the setting scale of the NC thermostat
(STO 011) at +11°C. This setting assures closing of the switching contact before 0°C.
