Changing From Mechanical to Digital Timer for Worcester Greenstar 25cdi


Postby paulhypno » Sun Nov 25, 2018 9:25 am

I have a Worcester Greenstar 25CDI with a mechanical timer (MT10) that is broken (no surprises there!). There is no room thermostat fitted. I want to replace the mechanical timer with a wireless timer/programmer and am looking at the Drayton LP20RF Twin Channel Programmer & Digistat + RF. Both the broken MT10 and the LP20RF have a clip-in fitting so, looking at the fitting instructions for the LP20RF it will just fit into the female socket. Is that all there is to fitting it?

I ask because there's a diagram in the Instruction Manual that shows a possible wiring for Ns Ls & Lr but I believe that is only for an external timer/thermostat. Am I right in thinking that there don't need to be any internal wiring changes?

Simply Build It

I've resolved this myself, but just for anyone else who might want to know the answer is: Yes it's just 'plug 'n' play'.

I bought Drayton LP20RF Twin Channel Programmer & Digistat + RF (same as WORCESTER DT20RF )

Unplugged the broken mechanical timer, and plugged in the new Drayton timer and it took 10 minutes to fit.
