What I need to know is will this just slot into boiler and replace the wireless receiver. If not can h you suggest an alternative? Regards Craig

Q: Hi would this be compatible with the Baxi Platinum / When mine was installed they used a Mechanical Timer but would rather change it over to digital as I need different temperatures set for different times.

A: Yes, but it is still on/off only. You will need a programmable thermostat for different temperatures. If you can let us know if you have an existing thermostat (and if so which one) and we will recommend one.
Q: Is this compatible with a main eco elite combi boiler? And easy to install?

A: Yes it is. It's a simple install.
Q: Is this compatible with a baxi combi 105 HE

A: Yes it is.
Q: When you state that wiring harness is not included does this mean that there is a harness and may be available from you at additional cost? Thanks

A: The harness is boiler specific as it is the cable that connects the clock to the boiler. So it should be obtained from the boiler manufacturer. If you are replacing an existing clock, you don't need to obtain one as you just connect the new timer to the existing harness.
Q: Hi, could you tell me if this is compatible with a Pottertom Performa 30he please/

A: I'm afraid not. I would recommend changing the thermostat for a programmable thermostat instead.

A: Yes it is.
Q: Hi... Will this replace the mechanical time on an Alpha Intec 28X? Will I need any additional wiring? Thanks

Q: Hi, Is this compatible with a Vokera Compact 24 SE boiler, to replace the valve cover and clock kit? If not can you advise of a suitable alternative to the mechanical time clock please? Regards

A: I'm afraid not. I would recommend fitting a programmable thermostat instead, as this will be easier, cheaper and give you more control over the Vokera timer.

A: Yes it will.

Q: Will this fit a Ferroli Modena 80E. Thanks

A: Yes it will.
Q: I have a Main combi 30 HE with no timer fitted at all. Will this timer fit straight in or do i need extra parts

A: You will need a wiring harness to connect the timer to the boiler PCB. This is usually supplied with the boiler and may be curled up behind the timer blanking plate.
Q: I have a baxi duo tec 28HE with no timer unit fitted. Will i require a wire harness to be able to fit this timer, I obvoiusly will not have the wires from a previous timer to re-connect.
