Thermal Actuator wiring

[Darren1962]

Hi
i am not a plumber, nor am I an electrician.
Just recently purchased an underfloor heating thermal Actuator. The wiring is as follows, brown, blue, black, grey. The old actuator is red, red, yellow, yellow.
can any one tell me what colour matches with what colour?
Thanks

Yellow and yellow are you motor opening and closing

And reds are you contacts to say when it’s open

Brown and blue are your motor opening and closing (if you wire in and it doesn’t open after 10 minutes flip these around )

Black and grey are your contacts to say when it’s open

Brilliant.
Thanks very much, I’ll wire it in the morning.
