Return preheating

The Return preheating function can be used for trans-
ferring heat from a heat source to the heating circuit
return.
The allocated relay is energised when both switch-on
conditions are fulfi lled:
• the temperature difference between the allocated

sensors has exceeded the switch-on temperature
difference

• the temperature at the outdoor temperature

sensor has fallen below the adjusted outdoor
temperature

With the summer switch-off option, the return pre-
heating can be suppressed outside the heating period.
