Swapping thermostat for Digi one

[Rich1e]

Im going to swap out my current thermostat & programmer for a digital type setup.
The thermostat itself is battery powered but the programmer is obviously mains powered, will it be a case of just swapping the programmers like for like regarding wiring.

thanks in advance.

If you can make & model of the programmer, you may get better advice, from those that know.

Basically I sweet talked the site manager into giving me a digi thermostat & programmer. he has 5 minutes ago dropped off a Honeywell CM707 Programmable Thermostat, I asked him where the programmer was and he replied thats all I need!

I know naff all about plumbing electrics but im pretty sure there is going to be some sort of control panel needed somewhere along the line.

Any help would be greatly appreciated.

Looks like I need an actuator!

Any idea what one I will need?
