4.6.8

Fan Speed at DHW full load ( )

Adjustable from 18% to 100% output (= approx. 1300 to 7000 rpm).
This value sets the maximum output of the boiler.
4.6.9 Forced part load time after start (HTG only -
Adjustable from -
This value sets the period of time the boiler will stay on part load at
start up during which time the flow temp is limited by part load temp
set point (parameter )

4.6.10 DHW control stop set point ( )

Adjustable from -

4.6.11 DHW control option ( )

This value sets the DHW control option.
Three way diverting valve (port A - HTG and port B - DHW)

4.6.12 HTG cut in temp ( )
Adjustable from (-10) to
This value sets the below actual return temp at the moment of

control stop during HTG demand.
A control stop occurs when the flow temp equals the flow temp set
point +5 °C.
HTG cut in temperature = actual return temperature at the moment of

4.6.14 Maximum delay time ( )

Adjustable from -
This value sets the maximum off time following a control stop. The
minimum off time is preset to a fixed value (150 seconds).
4.6.15 Start and end point analog signal (
Start point (0 V): adjustable between
+ °C.
This value sets the required flow temp at 0 V signal input (restricted
by the minimum flow set point).
End point (10 V): adjustable between +
(+299) °C.
This value sets the required flow temp at 10 V signal input (restricted
by the maximum flow set point).
