Test Operation
[E] Service mode
[E-00]
Vacuum mode
When recovering/vacuuming of the indoor unit is needed, field setting [E-00] should be activated. It
will force the unit into thermo OFF and will open the expansion valve of the indoor unit R-134a
circuit so full vacuuming is possible.
By default [E-00] = 0, set to 1 to enable the vacuum mode.
Note :
Do not forget to restore the field setting [E-00] to the default value when vacuuming is finished!
When [E-00]=0 is set to 1 (recovery mode), [E-04] can be set to 2 to enhance recovery of the refrigerant.
[E-04]
Pump only operation
When commissioning and installing the unit it is very important to get all air out of the water circuit.
Through this field setting the pump can be operated without actual operation of the unit. By doing so
this will enhance the air removal from the circuit. The pump can operate at different speed:
[E-04]
= 0 normal operation of the unit (default)
[E-04]
= 1 low pump speed operation (pump only, unit is not operating)
[E-04]
= 2 high pump speed operation (pump only, unit is not operating)
Notes :
1. If you select [E-04]=1 or 2 and [6-00]=1, the unit will activate the domestic hot water 3-way valve.
This function is a helpful feature to get all air removed out of the system (as well in space heating as
in domestic hot water heating).
[E-04]=1 or 2 & [6-00]=0 => Pump operation of 20 minutes. 3-Way valve in space heating mode.
[E-04]=1 or 2 & [6-00]=1 => Pump operation of 10 minutes. 3-Way valve in domestic hot water
heating mode.
2. Do not forget to restore the field setting [E-04] to the default value when commissioning is finished!
3. When using thermostatic radiator valves, make sure to open all valves during air purging operation.
