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 ?

Connect the Towerstat as per the volt free switching diagram on page 10 of the Towerstat manual (link wire removed). Connect ‘Live from load’ to boiler RL (X2 terminal block), ‘Switched live output’ to boiler RI. Also connect live and neutral to the Towerstat from CL and CN terminals.
See boiler installation manual Fig 12 and 13 here: http://www.worcester-bosch.co.uk/ca...instructions-for-28i--discontinued-nov-05.pdf
