Correction: where I said the new stat should be between live and
valve-BROWN, I meant the ON-HW terminal of the Programmer and
valve-BROWN.

Otherwise the zone can call the boiler even when the timer is off.

Do you want to have two separate time controlled CH zones or two CH zones
that are controlled by one master time control programmer and then uses two
stats (one a programmable one) for each of the zones?
