Differential pressure bar (x 100 = kPa)

Additional cold water capacities from the thermostatic air vent under start-up conditions:

Under start-up conditions when the condensate is cold the internal thermostatic air vent will be open and provides additional capacity to

the main valve. The table below gives the minimum additional cold water capacities from the air vent.
