how to connect zone valve to thermostat and transistor ?
 
3 Attachment(s)

I have a problem to connect the thermostat/transistor wires to upper part of the zone valve (the picture with a red circle). I needed to replace the valve as it was leaking water. Now the new valve is on and the new cap is on ..however the wires are still dangling there ;-))
There is one wire coming from transistor - red wire
There are 3 wires coming from termostat (red, black and white). My termostat is heat only (I am heating running hot water in baseboards) so I am not sure the black wire is to be used. Can somebody pls let me know which screw of the valve cap I shall connect the wires to?. Maintenance guy told me if I do it wrong .. I might fry some part in new valve cap or termostat. Thanks a lot for your help

this is a 50 unit condo. the hot water is provided in the pipe. Problem is I have received another diagram from an electriciain ..he wants to :

Red wire from Transformer to Red from Thermostat.
The white wire from transformer to screw marked "2" on the valve.
The other thermostat wire (I don't know the color) to screw marked "1" on
the valve.
That should do the trick.

I do not think so I have one (heat anticipator) in the thermostat. pictures attached...thanks for all your help !!
