Connecting the resistor
The electrical schematics above present a traditional connection with
permanent power supply to the control system. Connect an electrical
resistor with integrated thermostat to the electrical power only, without
going through the control system. Use a different mains supply for the
control system and the electrical resistor with integrated thermostat.
CAUTION
The forcing functions, set-point temperatures for the
backup and 3-position switch on the front of the control
system are not used with a resistor with integrated
thermostat.
