Hi,

I’m trying to replace the dial thermostats for the UFH at my flat, and I’m having some trouble with the wiring.

The instructions tell me to label 3 wires, but the existing thermostat has 4. As per the wiring diagram, the Heatmiser thermostat has a Switch Live (SL), Live (L), Neutral (N) and a Timer Live.

My confusion arises from the Timer Live wire. I’m guessing this wire isn’t necessary for the Tado, should I just terminate it and cap it? Will this cause issues with the rest of the system?

    I have exactly the same problem. Contacted support for assistance. The instructions were incredibly detailed for an old Honeywell thermostat I have but poor for this JG DS-SB.
