Display of actual primary temperature inside boiler.
Default display is of actual primary temperature inside boiler.
Display of desired primary temperature inside boiler
Press key (6)
up
and release to see desired primary temperature inside
boiler. (Calculated from selected heating curve)
The Display shows the desired temperature of primary water in the
boiler. The value is shown for 5 s, after which display reverts to show
actual temperature of primary water in the boiler.
Heating curve selection (ensure correct choice of radiator or
underfloor curves – see part 3.5.2 page 12)
Press key (6)
up
and hold for 5 seconds to enter curve selection menu.
The display blinks showing current curve setting
