Power failure
020301 15:10:18
Info
Probable causes and actions:
• One or two phases are missing to the heat pump.
Action:Check the fuse (or MCB) for your heat pump. If the bottom plate is loose then the fuse has
blown and must be changed. If you have MCBs, and they have tripped, move the switch to the up
position.
• The emergency thermostat is not in the 0 position.
Action: Check that the emergency thermostat wheel is turned to the anti-clockwise end position.
ALARM
Electrical cassette
020301 15:10:18
Info
Probable causes and actions:
• The electric water heater MCB has tripped.
Action:Reset the MCB by pushing the switch upwards. If the fuse blows again then the heater could
be faulty, contact your installer.
• The overheat protection on the electric water heater has tripped.
Action: Reset by pressing the button on heater's protective cover until it "clicks". It could depend
on a bad flow over the heater caused by the circulation pump standing still or a clogged particle filter.
Check the circulation pump and particle filter.
