High bypass temp. WRA12 Water temperature in
bypass > 50°C
Possible extended recirculation of water through the
bypass. Check:
• that the humidification capacity set on screen Dc18 is
equal to the no. of nozzles x capacity of each nozzle;
• that the zone can deliver a flow-rate of water ≥ the
minimum flow-rate supplied by the pump;
• that the NTC probe is connected to terminals J5.2-J5.3
- Warning
Low pressure - Pressure measured by
probe HPS < 60 bars
with pump running Possible small water leaks at the outlet, check tightness
of the hose fittings and make sure there are no leaks
from the drain solenoid valves DR1 and DR2.
