Display message
Reason
The display describes:
The actual operation for heating or hot water
If a heat demand is activated
The temperature setting
The temperature measured
When mounting the bottom part of the siphon, before commissioning the water heater and/or after maintenance, the siphon
must ALWAYS be completely filled with water.
This is a safety measure: the water in the siphon keeps the flue gases from leaking into the plant room via the condensate
drain.
