i o
This parameter determines whether a pasteurisation demand takes priority over a
CH demand over the boiler. A value of 0 gives pasteurisation priority, a value of
1 gives heating priority.

This parameter sets the differential used when the DHW vessel is controlled by a
temperature sensor. This is the temperature below the setpoint temperature which
the vessel must reach before the firing sequence will restart.
Menu B: Hot water
B G
D H i d e t g r
This parameter is used when the DHW vessel is controlled by a temperature
sensor. If the boiler detects an accelerated hot water demand (e.g. a drop within
1 second) the firing sequence will start even if the differential temperature has not
been reached.
