Problem with Honeywell thermostat DTS92E1020

[-Chris-]

No heating is coming on at all over the last few days, so have a really grumpy, cold family - hopefully someone here can help! I've checked the boiler and that seems to be working okay. No issues with hot water. When I look at the thermostat it says 18.5, but when I click either the downward or upward arrowed buttons, it then shows 5.0, but it doesn't move from that number regardless of how many times I press either button?

Any help really appreciated.

Thanks.

Chris.

Can you set it to manual and then try to adjust the temp with the buttons?

Not my area but as I`m sitting here waiting for somebody.
Google say`s wireless so have you checked the batteries?

How do you set it to manual please?

Yep, first thing I did was to put in fully charged batteries.

Is there a wireless receiver near the boiler?? It should have an override button on it. Press it does the heating come on

What happens if the press the power button?

Thanks for the quick responses guys, I'm at work at the moment, so not able to view those at the moment. Will update when I get home tonight. Any other ideas in the meantime, are also very welcome.
