The internal backup heating function is used for operating the electric heating
for backup heating with current from the mains. For this purpose, the power stage
is switched on. The switch-on and switch-off temperatures Ton and Toff are used
as reference parameters.
If the temperature falls below the adjusted threshold Ton, the power stage and the
relay switch on. They switch off, if the temperature exceeds Toff.
The reference sensor is selectable. If the maximum temperature is exceeded at S1,
the backup heating is interrupted. Upon saving the function, the note Use of mains
current possible! appears.
