Output
This function can be used for transferring heat from a heat source to the heating
circuit return.
The allocated output is energised when all switch-on conditions are fulfi lled:
• the temperature difference between the allocated sensors has exceeded the
switch-on temperature difference
• the temperature difference between the allocated sensors has not fallen below
the switch-off temperature difference
• if Summer off is activated, the temperature at the outdoor temperature
sensor falls below the adjusted outdoor temperature value
With the summer switch-off option, the return preheating can be suppressed out-
side the heating period.
