Setting time is not in manual that we received, however, we did get a separate sheet: Buttons top left-right are A - Clock adjustment B - Operating Mode selecting C - Override Buttons bottom left-right are: D - - E - Programmes F - +
To set clock: 1 - Push A 2 - When the DAY and the CLOCK icons on the LCD are flashing use + and - (D and F). You should set the day of the week (1 = Monday, 7 = Sunday). To confirm the day press A. 3 - The HOUR and CLOCK are flashing use + and -. Confirm with A. 4 - MINUTES and CLOCK are flashing use + and -. Confirm with A.
My LCD is not working correctly, so I have to press the screen gently to see what icons are displaying. Annoying.

I have a 9610 thermostat turns on and off to frequently


I am guessing but the thermostat is either faulty or is in conflict with another thermostatic device in the system. The room thermostat measures the air temperature in the room but with a modern intelligent boiler there will be other sensors measuring all sorts of things including the water temperature.

Personally I prefer to have thermostatic radiator valves rather than a room or zone thermostat.

Kenwood Electric Oil Heater. Model EW7507EK. Can anyone tell me what color order of wires onto the circuit board? I feel like an silly for not taking a photo before starting the repair. F3-5


Look carefully on the board itself. Sometimes the wire color codes are labeled right next to the connector. If not, there may be some other letter codes and these should match the ones on the thermostat.

Be sure the thermocouple is still working, clean the contact points with crocus cloth and be sure the voltage going in to the controller is correct.

Johnson Starley boiler main board fuse blowing


Chances are the fuse on the circuit board is for control circuit protection. Take note of the location of all the thermostat connections on the circuit board and remove them. Do this with the power OFF. Replace the fuse and re establish power. If the fuse did not blow, the problem is in the wiring to or from the thermostat. It could even have the insulation rubbed through and making contact with the side of the boiler or a mouse could have chewed through the insulation causing a short to a metal object.

Once the issue with the thermostat wiring is resolved, reinstall the low voltage connections and you should be good to go.
