Digital Thermostat Issue

I have a main eco elite compact 30kw combi boiler (rebadged baxi 630) paired with a crappy salus T105RF stat.

The stat heating worked ok over winter but i noticed the intermittent pump recycling with the radiator symbol flashing a few times despite no heating demand.

Now the weather has warmed its noticeable and also the burner would kick in for a minute before it goes off with the rad symbol flashing. Hot water works fine, but with the recycling and the usage of gas means its not energy efficient.

The lowest temp setting on stat is 7c and i have set it at that to see if it makes any difference, the boiler is not subject to cold temps in its location.

The only way i got it to stop doing it is to switch off the receiver.

Am i right in saying the wiring could be wrong or the stat could be faulty?

Is it worth resetting the stat to see if it works?

Any advice appreciated.
