Hi all,
Would very much appreciate some help here.
We've moved to a new property that has a Grant Euroflame 70/90 oil-fired boiler and a Sangamo Choice PR2 two-channel programmer with cylinder stat but no room stat. The Sangamo has a standard backplate with a black wire for HW=ON (t3) and a grey wire for CH=ON (t4) and DIP switch set to gravity.
We would like to add a wireless room stat and Honeywell have suggested their Sundial RF2 Pack 2 would be a good replacement for the Sangamo.
Do I need to set the Sundial for gravity and if so, how?
Can I leave the backplate wires as they are and just swap in the Sundial?
For info, the previous owner said he used a Hive and just put the Sangamo back without needing to change any wiring.
Many thanks in anticipation of your help!
