I'm not entirely sure what this achieves. Is it so you can have a wireless controller giving load compensation as well as having timed pre-heat? Personally I don't like the Honeywell on/off type of modulation when true flow temperature modulation is supported by the boiler.

I’m drawn to the CMT927 for a number of reasons:
Wireless
Portable
Optimised start
Optimised finish
Other features offered by similar controllers
Then fit the DT20 to control the pre heat timing.
Knowing I can fit two controllers, I have dismissed the Worcester Bosch DT10RF Optimiser as an option in favour of the above combination. The system is not being installed by a WB AI.
I’ve seriously considered the Worcester Bosch FR110, it offers most of the above, and more, except wireless and portable. Advantages would be proper load compensation and, it can also store 6 separate weekly heating programmes (I’m a shift worker). However, I believe my circumstances require portability.
I’ve started a new thread on “Fixed vs Portable Thermostat” as this one is getting rather long (and off topic).
