between board and fan.
Voltage on components -
reactor and capacitor.
Replace the component(s) if required.
Check/correct:
Board supply voltage.
Replace the component(s) if required.
De-energize the unit and re-energize it
If the problem persists, replace
the component(s).
Check/correct:
Water fl ow in the system.
If the pressure switch (DPS)
is on in the master unit.
DPS contact is opening and
closing - operational?
If the system has three units or less
and DPS is not used, make sure that
the setting is OFF in control.
The unit must not operate at temperatures
below 5 ° C. If the temperature is above
5 ° C, check the electrical connection
and physical connection of the room
Check/correct:
