I did check with Heatmiser first and they recommended replacing the DY-107 with this 16 amp Neostat-e V2 for UFH, and the rooms are controlled with their independant stats.
Also the old DY-107 which is only 6 months old, has only been wired in with the 3 wires
Would the L1 on the old equate to...
Hi Eric,
the old thermostat/programmer allowed for setting up the heating timings but is awkward to use hence changing to the Heatmiser system which matches the other room stats (NeoStat-e V2 with NeoHub)
It's all electric underfloor heating with a Nibe F205P electric boiler
Hi, my old thermostat/controller (DY-107) only has 3 wires as per the image (which is the lower left in the diagram), Live, Neutral and L1 (black) and is for electric underfloor heating.
The new replacement is a Heatmiser neostat-e v2 and i'm assuming it should take those 3 wires as L (Live)...
