temperature > 50°C
Prolonged recirculation of water through the bypass is
possible. Verify:
• that the humidifi cation capacity set on the Dc18
screen is equal to no. of nozzles x capacity of the
single nozzle;
• that the zone is capable of delivering a water fl ow rate
≥ the minimum fl ow rate supplied by the pump;
• that the NTC probe is connected to terminals J5.2-J5.3
