8.4 Summer operation
The degassing of the network water is not necessary if the circulating pumps of the system are shut down during Summer because gas-
rich water cannot reach the device.
In this event, use the Customer menu to shut down the degassing action to save energy.
After Summer, select the "Interval degassing" degassing programme in the Customer menu or "Continuous degassing", if required.
For a detailed description of the selection of degassing programmes, see chapter 8.1 "Automatic mode" on page 47 .
Note!
The pressure maintaining feature of the device must remain operative in Summer.
– Automatic mode remains active.
8.5 Restarting
CAUTION
Risk of injury due to pump start-up
Hand injuries may occur when the pump starts up if you turn the pump motor at the impeller using a screwdriver.
• Switch the pump to a zero-volts state before turning the pump at the fan wheel with a screwdriver.
ATTENTION
Device damage due to pump start-up
Pump damage may occur when the pump starts up if you turn the pump motor at the impeller using a screwdriver.
• Switch the pump to a zero-volts state before turning the pump at the fan wheel with a screwdriver.
After an extended standstill time (the device is de-energised or in Stop mode), the pumps may jam. For this reason, use a screwdriver to
rotate the pumps at the fan wheel of the pump motors before restarting.
Note!
A jamming of the pumps is prevented during operation thanks to forced starting action (after 24 hours).
