I need help

sssssiiiiimon

Hi guys

Firstly I would like to thank anyone who gives any feedback whatsoever and say that I have searched for a solution for days and have found nothing. Well nothing that makes sense to me.
I have attached pictures to help out here.

I live in an apartment which has underfloor heating. It is powered by a sunvic unit. There are 2 thermostats on the walls one in our sittingroom and one in the bedroom.

Previously all I would do is press the +1 or set a time on the select xl unit and voila the heating would come on. AFAIK the select xl unit powers the other unit (I've no idea what this unit is called) the other unit is the one hooked up to the rf thermostat controls on the walls.

Problem is the batteries died over the summer and typically I didn't replace them in time. I know dumb move.

Now there thermostats don't send the signal to the large unit to tell it what temperature to fire up to and I've no heating.

My question is does anyone know or can point me in the direction to where I can have my rf thermostats talk to my heating unit.

I hope that makes some sense.
