Hi everyone,

I need help in wiring a 3 wire (Grey, Orange, White) Wilo normally closed zone valve...

I have Weil Mclain 97+ boiler which has a built in 3 zone card and 24V transformer...

I don't know which wires go where and what to do ... plz help...

My t stat has only 2 wires (RED and WHITE)

i've attached some pix as well... It comes with 2 leads (yellow and red) for wiring to boiler or stat i guess.
