To the specialists amongst you all...
I've been using Honeywell's CM921 wireless thermostat together with the on/off R6660D Relay box...
This system works very much to my satisfaction...
I am however contemplating on switching to the Evohome system...
It says in the user's manual that this type of relais box can also be used for
communication with other Honeywell products such as HR80, HM80 and HCE80...
Of course the Evohome and HR92 valves are not mentioned because they simply did not exist at the time...
My question is simple...
Can I use my existing R6660D on/off relay box with the Evohome system...?
Thx for any feedback...
