I have a Daikin Altherma Low Temp Split system. Just had a recent power outage that last 4 days. Power back now but the underfloor heating water is not running. The display panel says the unit is running for heating, but the outside unit is doing nothing, fans not spinning. However, for domestic water heating, the outside unit kicks in fine. Any ideas? No error codes.
Unit outside is a ERLQ016CAV3
