Replace 3-wire thermostat

[justaddice]

Hi,

My old thermostat is a RMT-230 (see attached photos, inc wiring).

I am replacing it with an OP-TOUCHRF from tfc-group:

I tried wiring Yellow to L, Red to N and Blue to Out1.

I guess I need a small link wire to Out2 from N, but wanted to confirm. I also noticed the labels are different on the technical PDF, so no wonder I am confused.

Thank you

DO not do that or you will need a new thermostsat, you need to connect a permanent L & N to L&N on the new stat, then the red ane yellow wires in the exissting stat go to live in and live out in new stat, either way round it doesnt matter, but you cant just swap the existing wires you need a permanent live to the new one which the old one doesnt have
