mode
(Summer), the pump operates during the production of domestic
hot water. With an Easymatic, the pump shuts down after the pump
flow switch-off delay. The heating/domestic hot water reversal
valve remains in the DHW position.
- With room temperature thermostat
- The pump switches off 2 minutes after the contact with the room
temperature thermostat is opened. After the production of
domestic hot water, if the room temperature thermostat is open,
the pump switches off after 5 seconds and the heating/domestic
hot water reversal valve remains in the DHW position.
With Easymatic or Easyradio
- When the desired room temperature is not reached, the pump
operates continually. When the room temperature is too high, the
pump is shut down after the pump switch-off delay (See
"Easymatic"). If the room temperature is too high after domestic hot
water production, the pump shuts down after the pump switch-off
delay; the heating/DHW reversal valve remains in the DHW
position (See "Easymatic").
