Required settings for White Rogers Thermostat with Zone Valve

[something1965]

My setup at home...

Vanee Heat Exchangers (fresh air inbound preheated by exhaust air) then to:
Hot water Coils (Actual heat supply) - Sheet metal box with snake of copper pipes inside where air passes through then to air cavity in floor.

2 way 4 wire Zone Valve normally closed (without 24 volts applied) will supply hot water to the coils as well micro switch inside will activate the small inline pump.

The main floor has both a White Rogers Thermostat 1F81-261 and a Vanee Humidifier control.

When I call for heat the valve will open and supply the hot water as well activate the relay for the 120 volt pump.

White Rogers control is set to AUTO
What I noticed was when the temp reaches it's goal the Vanee Exchanger stops blowing
Problem:
but the hot water valve (and water pump) does not sync and turn off as well.

Question:
Is there something in the White Rogers that I don't not understand for settings?

Settings are:
SL
EMR - Off
Compressor Lockout - Off
2nd Stage - OFF

Proven that its not a faulty zone valve and just wanted to eliminate White Rogers before checking on wiring.


Thanks

There won't be too many people on a UK forum with experience with these systems!

as well micro switch inside

Micro switches inside 2 port valves can fail and energise things when they shouldn't.
Though you say you've already proved the 2 port valve is not at fault?

Yes the Micro Switch will activate the relay/pump when it swings open the valve.
When I disconnect one wire (24v) the Valve will close....just wont close in sync with blower/exchanger

"2nd Stage - OFF" I have changed this to ON so will need to visit the dungeon to test when time.

Did not work.

I do suspect the White Rogers somehow but need to play more and verify wires.
