A quick heads up because I know there are a lot of people who are searching for an easy replacement for quite a few different models Honeywell RF programmable thermostats. The main ones being the CM927, CM921, CM727 and the CM721. The new Hanicks Honeywell Pro is a straight / easy swap for all these wireless thermostats. The full list of models the Hanicks Honeywell Pro [pictured below] replaces are as follows: CM721 CMS721 CM727 CMS727 CMS727E1016 CM927 CM921 CMS927 CMS927B1049.

Hanicks Honeywell Pro model replaces them all

This is a 7-day programmer and comes with relay / receiver. It's also compatible with the following relays should you want to use one you already have with the new programming unit: BDR91, HC60NG, R6660D, R8810A OpenTherm Bridge. You can of course just use the brand new one that comes as part of the package. Fitting and binding guide comes with the programmer. If you have any trouble with the install, there is a video link that that Hanicks provide which will guide you through the process.

Quick specification. 7-day programming, two on / off periods each day, auto / manual options, fire symbol on screen, service reminder, boiler plus compliance. Takes 2 AA batteries.

This unit is also being sold by another company using a different name. That name is Adept. But regardless of who you buy it from, Adept or Hanicks [and now in 2023 there's also LavaTap], the product itself is made by Resideo and both / all companies are selling the exact same product. They all have very good review scores for service and support, and the product is highly rated for being accurate and easy to use.
