How do I wire this 2 port valve into system?

sorry was asleep LOL
bathroom stat from heating on
can't see why it should hold open the valve as a loss of power to brown when heating circuit stat is satisfied would close the valve and break the contact on orange (brown and orange are not interconnected)

But he want to run the circuit independently, not on and off with the heating.
An Imaginary situation for you to think about.
RS to gray & brown, gray powers the motor, brown to the orange, orange to T4, for the valve to close you have to take the power away from the gray.
Second RS puts power to T4
T4 is also connected to the orange, which is also connected to the brown & gray.
OP didn't say not controlling through timeclock heating

that is a valid point will think on it over tea as i'm sure we can do it somehow

I haven't followed this thread in detail but here is my suggestion - apologies if anyone has already suggested this.
HW on at programmer --> drying room stat --> terminal 4 on boiler.
CH on --> room stat --> brown on 2-port valve
Permanent live --> zone valve grey : zone valve orange --> terminal 4 on boiler

Beat me to it mate. This will achieve exactly what the OP wants.
You have to break the common connection on T 4 boiler, or you will get a backfeed orange to brown so the valve will not close.
A double pole relay would do it, taking the common to the bathroom stat from the Htg off connection in the room stat should do it.

mogget your almost there!
my revised theory on this
1 valve fitted after bathroom rad flow pipe
boiler 3 to time clock
timeclock heating on to roomstat commons and grey of valve
bathroom stat calling to boiler 4
heating stat calling to brown on valve
orange on valve to boiler 4
2 valve
boiler 3 to time clock
time clock heating on to roomstat commons & valve greys
bathroom stat calling to bathroom valve brown
heating stat to heating valve brown
valves orange to boiler 4
can't see anything in that for it not to switch / work correctly

That's cheating you've added a second valve
Read my first post.
no i haven't, i have done a 1 valve and a 2 valve on the last post read it again
only to the OP someone else may want to have control of both circuits
Think again mate.
Terminal 3 (HW) from programmer direct to terminal 4 on the boiler. This will do the drying room.
Terminal 4 (CH) from programmer to brown (via room stat if fitted) on the MV.
The grey on the MV is to permanent live, when valve opens, orange becomes live (to terminal 4 on the boiler).
There is no way of any feedback from brown to orange. That is why grey on a 2 port is to PL. The valve motor (LNE) is completely separate to the grey / orange side of the valve.
Basically, the OP just needs to think S-plan minus the 2nd MV.
