How to turn on a boiler without thermostat

[Hasan Ali]

A really silly question.

My wireless boiler thermostat controller has packed in.

How do I turn on / off my radiators without using thermostat?
How do I set temperature without the thermostat?

Cannot see any button on my boiler to turn it on.
It’s a Greenstar i boiler

Thanks.

You should be able to use the grey button on the receiver (the small white box with a red light next to the boiler). Have you tried new batteries in the thermostat?

As @CBW but likely only needs one wire moving in the reciver. As to no thermostat, my house has 16, two wall thermostats, and 14 TRV's of which 9 are programmable. So losing the wall thermostat is only a problem as we approach the point where ready to turn heating off for the year.

Have tried with new batteries but no success.
These thermostats from CENTER are really bad quality.
This is the 2nd thermostat from CENTER that has packed in in the last 3 years

Avoid Honeywell then, made by the same factory!
