Boiler sometimes not shutting off

[Live&Learn]

Hi all.

I have a greenstar 30i with a Boss TPSRF51 thermostat.

I have set up the thermostat according to the instructions.

When the fire image (heat indicator) pops up on the thermostat, the blue boiler light turns on and fires up the CH. All good here.

When the fire image disappears, however (when the ambient termperature has reached the set temperature on the programme), sometimes the boiler light turns off, but sometimes it doesn't and decides it wants to cremate me.

I can turn the blue light off by switching the receiver toggle to off. A few seconds later the blue boiler light turns off, and I switch the toggle receiver back to on.

The receiver suggests there is constant connection with the control unit (indicated by the orange light) manual for it is here: https://dam.cityplumbing.co.uk/GY58Y/GPID_1000783265_TECH_00.pdf

Can anyone help me please?

Thanks so much.

Hello.

I think I have figured it out. It is working as it should now for over a week. I am posting here in case someone else has the same problem. I reset the dip switch on the transmitter and receiver to defualt (on-off-off-off) and push the little reset button on the transmitter. I had to put all settings and timings back but it seems to play nice now.

You have wired that wrong at the boiler end, the receiver end is fine, at the boiler end the blue wire in FS should be in the terminal with LR and the radiator symbol
