Replacing room thermostat

cloud_dog

Hi

I have an old room thermostat, Drayton Digistat 1 (from around 1996) which I need to replace.

It is connected to the boiler by wires and uses two electrical wires.

Any recommendations/suggestions or any considerations I need to be aware of? Or, are most basic room thermostats the same requiring the two wires and I should be able to pick from almost any (ignoring wireless)?

This is the current room digistat.

They were low voltage stat, look at the new Drayton digistat for a direct replacement you’ll need one without rf in the discription.

Hi

Thanks for the comment. My predominant concern is ensuring the reconnecting (wiring) is as straightforward as possible.

The current set up has Live / neutral connected but some on the newer devices have slightly different wiring depending primarily on the amp throughput.

For example the Drayton Digisat + I (non RF) has a slightly different wiring schema depending on amps.

I think my current Drayton Digistat 1 uses 2A, and if I am reading correctly the above Digistat+I also can be wired for 2A.

I can't see where you're getting the different schematic from for different amps.

If you only have 2 wires then almost any BATTERY operated (or un-powered) thermostat will do. It simply acts as an on/off switch across the wires. Some thermostats are mains operated and require an additional mains supply.

When I’ve changed them in the past I’ve just fitted the pt plus stat which is just a older version of the wired digistat.

I don’t know what the amp thing is to be honest and maybe a electrician will correct me but everyone I’ve done have be 12v.

if its 2 wire they will not be live and neutral it will be live and switch live no need for a neutral

Might be worth considering an upgrade to programmable stat optionally with remote access
