Some help required please,
Have recently had installed the following:
Keston C40 (opentherm compatible) boiler
Keston Spa 210 unvented cylinder.
It's an S-plan system.
Want to get the most out of the modulating features of the boiler in conjunction with weather/room compensation controls. A Theben Ramses 850 OT controller was provided but not installed because the engineer said it was only for underfloor heating - we do not have underfloor heating - and instead a Drayton wireless programmable digistat was installed. An outside sensor (Honeywell TA1 series) for weather compensation has been installed, though not connected to the boiler at the moment.
As I say, I would like to have a set-up which takes advantage of temperature/weather compensation, but need to know what control to buy if the Theben is not suitable - is it really not suitable?
Also, I have no time control over hot water supply at the moment either. I thought the Theben device would provide this control too. Am I wrong? Was the heating engineer wrong?
To summarise: I want a control/controls to provide temp/weather compensation for CH, plus time control for hot water.
Thanks in advance.
