Wireless thermostat problems

[Fed_up]

Hi all, desperately looking for advice. I'm a private renter, not a plumber, but usually good at fixing basic things. We convinced our landlord to fit a new boiler last winter and when fitted a wireless thermostat was put in (previous system used only TRVs and timer).

Since then we've had an issue where sometimes the thermostat turns the boiler on but fails to turn it off when it reaches set temperature, and sometimes the heating just comes on seemingly randomly when the thermostat is not calling for heat.

In both situations if I turn the thermostat up so it starts demanding heat again, and then turn it back down the burner switches off.

Have tried moving thermostat to different locations in case it was a signal issue but that hasn't worked.

It's driving us insane, it's only a small one bed flat so if heating is on even a small amount more than needed it gets boiling in here! It means I can't have timer set for when we're asleep or when we're out, and when it's on I have to constantly be on the look out for when I may need to turn it off manually.

Landlord is an idiot so kicks things up when he tries to fix them. Help please! Is there a simple fix or if not what should I say is likely wrong to landlords plumber?

Thanks

Is it a Salus wiresless timer by any chance?

Just had a look at the receiver and yes it is. Known for issues?

Yes and not the best quality wise best to get it replaced with a Honeywell or Drayton

I can't see my landlord doing that unfortunately. Is there anything I can do to prevent it malfunctioning? Is it a poor signal issue?

Just a poor thermostat issue really. When was it fitted?

Is it still in warranty?

Around February I think.

So 10 months ish? Call the engineer back and get a new salus one and hope your lucky and it lasts longer this time.

If the unit is a salus rt300 the issue is down to the frequency selector pins. These pins come pre set at the factory. If the installation engineer was stupid enough not to change the pins then any other salus unit with the factory pre set pins within range of your property will also be controlling your boiler and your unit will be controlling their boiler. These pins are easy to change, just follow the instructions in the manual.
