I think you left a word out.
Weather comp may determine the amount of heat delivered to the system, but it does not control how this heat is shared between the emitters.

thanks D i did indeed leave a word out...
Client opted for Viessmann Vitodens 100- W boiler. System boiler now fitted and running after nearly a week of no heat in the house and unvented cylinder running on electricity
Three heating zones retained with MV auxiliary switch looping 1 and L to run boiler. Cannot get programmer to control HW MV
Since boiler if fitted to third party UV cylinder, am using the interface connected to loom plugs marked '5'. Take it 240 to this interface tells the boiler to switch flow to ' cylinder' connections and loop applied at 1 and L to run the boiler. When 240 is removed from interface, boiler reverts to heating rads. Is my understanding correct?
TIA
