28i RSF and Wireless Towerstat RF ( Selectable Volt Free )
Hi
I am trying to fit a Towerstat RF wireless thermostat to my old age boiler a 28i RSF, this is the old grey one with only a mechanical timer unit rather then any thermostat.
I have found a guide that mentions the CM907

but i'm not sure what the equivelent AB connections are on the Towerstat
Can any help ?
