Long reply warning!!
Firstly, this kit is for a properly functioning 3 zone system, upstairs CH, downstairs CH and HW, which is not yours.
If you had a working zoned system, 2 or 3 zones, and if you can find someone like the installer referred to earlier who done the Ember install for L'prof, it's just a case of asking for the different controller, and if he's up front about the cost of his preferred kit (Ember), then I see no reason that you shouldn't be able to ask for the Drayton, it's design is almost identical to the Ember.
That's the theory, but many of these guys stick to what they know. It's little wonder then that quotes are so high for grant aided work, net if grant, that you end up just doing a DIY job.
In your case you already have a botched system, as you have a two zone controller which is connected to a single Zone system, which may be a two Zone as it has a valve. Either the valve is faulty, or the installation of the Climote was botched. Who installed that? Was it another offer you received from an electric utility? Prior to the Climote, what did you have? Did HW work without without heating the rads? This needs to be sorted first, rather than adding an even more useless stat to your system.
Unfortunately, all these offers involve nothing more than swapping whatever stat you have for the offer one. They will never address your system configuration, and figure out what you already have, single zone, gravity two zone, pumped, zone valve(s) etc. They will swap a pair of wires and leg it.
IF you can get your system plumbing sorted, to at least give you individual zoning of CH and HW only without resorting to manually closing valves, then you can have the Climote working as it should. With this, you can then inquire about fitting (possibly with grant), a proper smart two zone system, such as the two zone version of the Drayton I linked earlier, whic is only €144, https://www.screwfix.ie/p/drayton-he...trol-kit/9575v
Other options are Tado, Nest, Hive, all capable of switching a 2 zone valved system.
Tbh, you'll need to find a genuine competent person to first examine your system and sort out your zoning. Many older systems consisted of a mechanical timer which just fired the boiler for everything, HW and CH, and then a wall stat which either turned on a circulation pump for CH, or a zone valve if the pump was already on constantly when the boiler fired. Adding a two zone controller to such a setup was beyond most installers, as they are generally designed for a fully independent 2 valve (S plan) or changeover valve (Y plan) system, not the cruder HW always, CH on a stat system I described. Some two zone controllers such asTado can cope with the wiring required to operate a gravity two zone, where HW is always heated, but CH is controlled by either the pump or a single valve. Wiring this correctly requires a little more know how than just swapping the old stat for the new controller stat, which may be what happened when the Climote was installed.
