Attic Cooler Thermostat

[Chuffchuff]

The layout in the attic is getting rather warm dispite my attempts to cool it.

I am trying to find a domestic thermostat that switches an extractor fan on when too warm, and off when cooler. I have an outlet for a fan and would like to automate the on / off.

I have searched tech pages on Screwfix, TLC-direct and similar sites but only find units that switch on central heating. None of them seem to have a contact for a "cold" circuit.

I can find units like Xpelaire which are good but expensive, I hoping to go down a cheaper route.

Has anyone walked this route before ?

Thanks

Won’t something like this do it. Switches on air con when required.

Hi
You need to search for a room stat with SPDT contacts. (SPDT = Single Pole Double Throw) in that the contact is a change-over type and makes when temperature rises above the pre set value, plus of course it makes on temperature reducing below preset value. You would use the Common and makes when Temp rises contact.
This one is listed as SPDT... https://www.bes.co.uk/room-thermostat-18636/ Check with supplier before ordering

Many Thanks for your suggestions.

Isn’t it annoying when hours searching, come up with nothing, and others find answers almost right away

The information indicates that they could be used. The BES has a Q and A form. I have asked the question so will see if I get a reply.

Unfortunately neither of them has a circuit diagram to check the functionality but at the prices both are worth an investigation.

Just to add that BES came back with the suggestion of using a Honeywell T6360B Room Thermostat Wired - 230V, which has a 10 amp load.

The T6360 ID seems to referenced to its external styling because there are a range of options based on that reference number T6360 xxxxxxxxx for a range of central heating uses.
