Why my Gabarron HHR Heater does not reach set temperature?
If your Gabarron HHR Heater doesn't reach the set temperature, ensure an adequate temperature is selected. Check for obstructions like shelves above or objects in front of the heater that could affect its output. Also, verify that the heater is appropriately sized for the room.
What to do if ERR4 is displayed on my Gabarron Ecombi HHR Heater?
ERR4 indicates an issue with the economy off-peak charge times or the absence of an off-peak supply to the Gabarron Heater, but it won't stop the heater from working normally. Ensure the isolator switches are on, no breakers/fuses are tripped, there is an off-peak supply, and the off-peak timings match the heater. Also, check if the safety cut-out has tripped.
How to unlock the keyboard on my Gabarron Ecombi HHR?
