Manual or automatic
There are 2 modes for purging air:
▪ Manual: You can set the pump speed to low or high. You can set the circuit (the
position of the 3-way valve) to Space or Tank. Air purge must be performed for
both space heating and tank (domestic hot water) circuits.
▪ Automatic: The unit automatically changes the pump speed and switches the
position of the 3-way valve between the space heating and the domestic hot
water circuit.
INFORMATION
When air purging in automatic mode, the first air purge is always for the main zone,
the second started air purge is always for the additional zone. To air purge the
domestic hot water tank circuit, choose [A.3.1.5.2] Circuit=Tank at the start of
the manual air purge of the main zone or additional zone.
Typical workflow
Purging the air from the system should consist of:
1 Performing a manual air purge for both zones
2 Performing an automatic air purge for both zones
INFORMATION
Start by performing a manual air purge. When almost all the air is removed, perform
an automatic air purge. If necessary, repeat performing the automatic air purge until
you are sure that all air is removed from the system. During air purge function, pump
speed limitation [9‑0D] is NOT applicable.
The air purge function automatically stops after 30minutes.
INFORMATION
For best results, air purge each loop separately.
To perform a manual air purge
INFORMATION
When purging the main zone, make sure the setpoint for the main zone is at least
5°C higher than the actual water temperature inside the unit.
Conditions: Make sure all operation is disabled. Go to [C]: Operation and turn off
Room, Space heating/cooling and Tank operation.
