Heating and GFCI
The orange degree indicator means heating is on. It can also appear in standby when frost protection is enabled and active.
A flashing red light on the side, accompanied by GFCI TRIPPED PRESS TO RESET, means the GFCI has tripped. After a deliberate monthly test, press the side reset button briefly; a check mark confirms reset. If it fails to reset or trips because of an electrical fault, have the installation inspected. Do not repeatedly reset or bypass a fault.
