New house with thermonet th232

[gaz1234]

Hello

I’ve bought a new house and I think there’s a number of rooms with electric under floor heating using thermonet th232 thermostats.

I’ve noticed that the date and time goes wrong street a period of time.

I’m wondering if they are losing power or they require batteries?

Aube TH232 7 Day Programmable Thermostat - Digital A/F/AF - Underfloor Heating UK

Any ideas?

Cheers

They don't have batteries, but should have a permanent 230V mains supply. Maybe if the power to the thermostat is turned off, then the settings are lost.

You can find a copy of the instructions for it here.

Do these become faulty ever?

I also have some 132-f which seem to be controlled by a sensor in the floor right?

Nothing lasts forever. But I have no experience of these devices to be able to advise their level of reliability

The floor sensor is to stop the floor overheating. I would expect the TH-232 to have a floor sensor too. As per the instructions.

Would this replace the 132f?

No that's just a basic thermostat for central heating. You will need one that is for underfloor electric heating with the facility to connect the aforementioned floor sensor.

The AUBE thermostat also has a pilot wire that allows remote control from a remote central controller. You may, or may not being using that facility.

Ah bummer, already ordered.
Their reviews said that the 232 did in fact work. https://www.amazon.co.uk/ask/questions/Tx4PFZYQ8630D/
Guess I could try without damaging?

The link you posted yesterday at 8:27AM is for a different thermostat it's described as "ideal for hydronic heating applications with standard and combined boilers" (ie Wet central heating)

The 232 above is described as being specifically for electric UFH so should be OK.

Ok will try

Be aware two type of electric underfloor heating, resistive (needs a sensor) and chemical (self regulating) not worked with RAYCHEM underfloor heating, but have worked with the trace heating version for pipework, worked well, but you needed to special bits that go with it, it came as a kit.

ok I’ll have a look

 

[gaz1234]

Ok do I need to turn power off to change?

 

[gaz1234]

They look very different. The new has its own back plate that can also take batteries (or batteries alone?)
The old one is electrical only.
Do I need to turn the power off to replace?

It would be a good idea unless you want an electric shock.

I think in your case I would advise getting a professional in to change it.
