INFORMATION
▪
You only have to perform a wiring error check if you are not sure that the
electrical wiring and piping is connected correctly.
▪
If you perform a wiring error check, the hybrid for multi indoor unit will not
operate by heat pump for 72 hours. During this time, the gas boiler will take over
the hybrid operation.
Prerequisite: Indoor and outdoor unit must be installed and connected.
Prerequisite: Make sure that the water temperature in the system is >25°C.
1 Heat up the water temperature in the system >25°C.
NOTICE
If the water temperature in the system is ≤25°C, the plate heat exchanger will freeze
and damage occurs.
2 Proceed with the steps as described in the outdoor unit installation manual or
outdoor unit installer reference guide to perform a wiring error check.
NOTICE
Make sure that the minimum required water flow in the unit is guaranteed.
1 Confirm according to the hydraulic configuration which space heating loops
can be closed due to mechanical, electronic, or other valves.
