162 FILL_WARNING Error is generated
immediately when the
pressure drops below
Minimal Pressure. Demand
has stopped, but no error
needs to be stored at this
time.
The water
pressure is below
the minimum
pressure level
refill the system until the
pressure is above 1 Bar or
14.5 PSI
164 LOWEXFLOW_
PROTECTION
Flow is too low, demand
needs to be stopped with
fan at ignition speed*, but
no error needed to be
stored at this time
not enough water
flow through heat
exchanger
Check functioning of the
pump. Check/open all
valves that might restrict
the water flow through the
unit.
Check for an external
system pump that
influences flow through the
unit.
Check if the system
resistance exceeds the
spare capacity of the unit
pump.
165 VSUPPLY_TOO

166 VSUPPLY_TOO
_HIGH
Main supply voltage too
