Wiring in a controller to a Vokera Linea 28

[stuartggray]

Why is is that the Vokera wiring diagrams refer to "TA, TA, =," for the three available wiring points for external controller fittings, but the external controller fitting diagrams refer to "T1, T2," ?
I'm confused. Does T1 mean the first TA and T2 the second TA?

Yours confusedly, Stuart.

What are you trying to fit?

The TA terminals are contol live out and switched live back!

= is just a spare terminal to join room stat and programmer in series!!

I'll be fitting a cm921 receiver to the boiler in place of a Danfoss TS715 timer.
