hi.
I am replacing my current Satchwell room stat with a Drayton RTS 1. The current stat seems very insensitive, a large temp gap between activations. In the process of figuring the wiring I think the current stat has been incorrectly wired.
The current stat has a normal three core cable with only L & N used and the Earth terminated. The L&N are connected to the stat as Live and neutral on the wiring diagram inside the stat. (see pic: )
when the stat has reached temp and turns off the boiler there is 240 volts metered across the L&N. When the thermo turns the heating back on the voltage across L&N is 0 but there is 240v across the N & earth.
I'm assuming that the Earth and live "coloured" wires are in fact Live and Switched live. but which is which?
The new stat requires 3 wires N , L & SwL. So any help would be appreciated.
Thanks
