temperature going very high

[agron]

My first post here.
Not the most technically minded person here but I can follow instructions.
We had an issue the other day where the wireless relay controller was acting up and I decided to do a reset and after some struggle, I managed to get the system up and running again.
Our system consists of UFH (HCC80R) with 4 zones and upstairs, we have 9 rads controlled by HR92. For UFH, we have the T87RFs.
Also, we have 2x BDR91 Wireless Relay Box and 1x CS92A Wireless Tank Thermostat. No issues with hot water and rads upstairs.

I paired UFH as per manual and guide on the net but in one of the zones (the kitchen), for some weird reason, the T87RF or something else is setting the temperature constantly to 25 degrees which is way to high. Despite me constantly brining it down to 20 via the thermostat or controller it goes up to the 'default' of 25.Batteries are fine.
In zone configuration, I tried limiting it to 20-22.5 degres but to no avail. Any help! Roasting here

A quick update.
I removed the zone (kitchen) from the controller last night and woke up even so toa temperature of 26.5 degrees in the kitchen. That's what the wall stat (T87RF) is telling us! The interesting thing is that the kitchen stat is diaplaying the boiler relay connection icon but not the fire sign (that the heating is on). Hasn't done that ever since the temp has gone crazy.
Not sure how the UFH controller can push up the temp so high in a zone when the zone is deleted from teh controller and why it's intent is to up the temp so high...
