Three ways valve

[cc260E]

hello ebverybody.

I have at home a "Chaffoteaux et Maury" gaz boiler (Hyxia II).

The three ways valve is giving problems (seems to remain sticky at heating posiition and poor warm water is delivered.

Can somebody tell me what kind of signals (voltage amps,etc) is feeding the 4 contact connector that is on the valve? I would like to stimulate it on a test bench

in advance many thanks
