Heater - Baelz Automatic 373-E66 Series Operating Instructions Manual

Operating Instructions

9. HEATER

We recommend to install a heating resistor to prevent condensation underneath the cover in the event of
● considerable fluctuations in ambient temperature
● high humidity
● outdoor installation
The heating resistor is controlled by a thermostatic switch "TW" (bimetallic contact). The heating is deactivated at a
temperature of approx. +60 °C and is reactivated at a temperature of approx. +40 °C. A continuous operating volt-
age is required for operation. The heating resistor is connected to terminal 7 and 8 of the horizontal terminal strip.
Please specify the operating voltage when ordering as it is required to determine the resistance.
