Danfoss102 to Tempus 7 no independant CH

[Brocott]

I've just replaced a Danfoss 102 with a Tempus 7 to get more programming flexibility and lo and behold I cannot get Ch independantly of HW. Whilst this isn't the end of the world (its what we had with the Danfoss) It would be nice to use CH onits own.

I seem to recall having this problem with a 102 replacement years ago and the solution was ro run an extra wire between the solenoid valve and the programmer (I seem to recall it was Wickes branded as opposed to Tempus tho').

I do not have full details of the Ch system as the house is rented but will answer any questions as best I can if I haven't given enough for a solution.

regards, Paul

A bit more info if its any help.

I've just had a look at the connections "block" . Orange, grey and white from the 2 port valve are not connected to anything
