      Good value replacements for my three Honeywell wireless thermostats

      Very good economic replacements for my three Honeywell wireless thermostats the screens to each of which had failed/become illegible. Programming is easy enough and they have the normal "copy day" facility. It's not too difficult for an amateur to bind these with the Honeywell actuators/senders. The only downside is that they are less sophisticated than the Honeywell items which bearing in mind the price is fair enough.

      Quick fix for original Honeywell CM927

      Easy to pair with existing Honeywell relay box, video instruction was clear. No issue with postage. However, I found the wireless signal is much weaker comparing original Honeywell Thermostat even with new battery. This means, often I have to physically bring it very close to the relay box to turn off heating in manual mode.

      Good replacement controller for the CM927

      The only reason I’ve given this product 4 stars - is because my only gripe is this; it does not display the time when you hit the side button and the panel lights up. A small thing, but for me a pain when it’s dark. The other negative element is the pairing with the boiler. The instructions given are not clear, so, the best way to pair your boiler is to follow the YouTube tutorial, which does include all of the steps clearly to successfully pair the boiler. The positive. It’s a great replacement for the old controller, and I would recommend it and I would purchase again in the future,

      couldn't be worse than the Honeywell original

      Cheaper than the substandard faulty honeywell original and was straight forward to setup. The flaw in the honeywell screens means they typically die within 5 years. Honeywell should have replaced these with no charge but alas. This is a good drop in replacement for me so far and was easy to setup.

      Great product at a great price.

      Accurately described as a straightforward replacement. Great QR link to supporting instruction video. It’s a simple procedure to replace existing controller made even more “comfortable” with this step by step short video. Simples!
