Hi, please could someone help me. My CH/HW system was installed in June '06 and the CH doesn't have a room stat. All radiators have TRV's but I would like a room stat as well. I have purchased a Danfoss TP5000-RF+RX1 programmable stat and am not sure where to wire it. The CH/HW system is currently controlled by a Danfoss FP715 Si, so do I wire the stat into this
