Through spontaneous pressure change in the water supply, the flow meter
(turbine) can signal that water is being drawn off.
This means the burner starts briefly although no water is drawn off.
The turbine signal delay can be set from 1 to 8. One step corresponds to
0.25 seconds.
Default setting : 4 (0,25 seconds).
The pump overrun time is started by the control system at the end of the
heat demand.
The following settings are possible:
• 1 to 10: overrun time in minutes (steps of 1 minute)
Default setting : 3 minutes.
This service function allows you to display the temperature at the flow tem-
perature sensor.
