Replace manual CH timer with digital programmer?

in 30 years I have had a LOT less problems with wired or wireless honeywell than any form of wired or wireless salus,,,,,
could you link to some actual facts of honeywell failures, and not just inept DIY installs of them?

The problem is that Honeywell have a one year warranty period and are simply not interested in the many failed displays that they have supplied.

I know of similar liquid displays e.g. Landis&Gyr Microgyr that are still working perfectly after three decades whereas many Honeywell displays have not even lasted three years!

Simply Google "honeywell display not working" approx 336,000 results in 0.65 seconds, take your pick but my post is based on many others experience as well as my own.

What you recommend is your choice but paying more for an inferior product is not my idea of common sense.

I hope I have understood your situation correctly.

Is it possible to put your programmer on continuous? ie., ON all the time - if yes - you could leave it on it.
Then, attach a wireless thermostat to your old thermostat(if you had one) - if not wire the relay for the wireless thermostat to the boiler.
The wiring are simple, but if in doubt its better to get a plumber/heating eng to sort it out.

This is what I did
- put my CH programmable timer to continuous(some Honeywell 7 day timer), then installed Honeywell CM907 (which is a wired 7 day programmable thermostat - brilliant, but wanted a wireless one a year later) to the old central heating thermostat.
Later replaced Honeywell CM907 to Netatmo - wifi thermostat. The relay is wired to the original location of the thermostat and the Netatmo thermostat is wireless and stays where ever I want it to be. I got a very good deal - sold my CM907 for £45 and bought the Netatmo for £75 (I believe its £145/- currently)

So, father in law (electrician) came round and said he has fitted a number of these timers/thermostats etc as replacements, so it looks feasible. He mentioned something similar to what I think you are talking about, a control unit fitted to the original wired thermostat with a wireless capability and connected to a a unit wherever we want it, which is also programmable so not in when we are at work etc.
I haven't looked into all options yet- except we have a seperate HW system controlled by a Honeywell wireless timer and thermostat and I have found some difficulty with making this behave as I want- I didn't find it that intuitive to use.
However, I'll look into various systems and see what is available, not completely against another Honeywell, but happy to look at different options.
Thanks all for your replies.
