Which wireless thermostat???


Postby Alvin Wyllie » Sun Nov 09, 2008 7:14 pm

Please can someone thoroughly recommend a wireless thermostat with or without programmer? I fitted a Towerstat RF thermostat controller a year ago which was brilliant until the operating range dropped to about 2 metres (Tower told me it's a common fault). Then a month ago I was foolish enough to buy a Siemens RDJ10 RF which worked when it felt like it but now the thing's packed up altogether (thank goodness). So I'm looking for a different one with 0.5 degree sensitivity if possible, like the Towerstat and preferably not more than about £50. Very grateful for your help!

I have been using the Danfoss model for about 2 years now. It has worked perfectly. The sender is located in the loft and the reciever is on the ground floor about 8m below. It only has 1 deg resolution though. The battery lasted 18 months before it needed changing.

Many thanks for that, Matt. Is that the RET-B/RX1 model?

I have tried unsuccesfully to locate a seller for this model. Could you please post this information if possible? Also, can it be used on any boiler, and is it difficult to wire at the boiler side?

I got mine off e-bay.

If you google "Danfoss wireless thermostat" you will get a list of suppliers.

Best prog room stat RF is the Honeywell CM927. It is a few generations ahead of the Danfoss in terms of ergonomics and reliability.

I have Danfoss Randall RT52RF these work fine, they are sensitive to a half degree drop, which keeps the room temperature very steady, they are portable and do get moved about depending on which room I am in and where in the room I am working.
