Will it fit an old Grasslin Towerchron T2002 timer? If so that will solve my problem.
I'm afraid I don't have any information on the clock used in that old programmer.
Hi,I have a Grasslin timer: FM/1STU 01.76.0017.1 which is on a chiller compressor, do you know if your timer will be a good replacement?
Hi. Yes it will.
Will this fit my Grant combi 90 v3? Diehl type 880 230v 50 hz currently fitted.
Yes it will.

I have a Grant Euroflame Oil Boiler with a timer switch which is a DIEHL Type 880 230v 50Hz. It has 4 terminals at the top rear with slide on connectors. Will the above be suitable as a replacement? Thanks

Hi. I'm afraid not.
No harness on new boiler Baxi 630 how would you wire it up from scratch
I'm afraid it is not suitable for the Baxi 630.
My clock on my boiler is not working so I can't put heating on timer would this fitting just replace old one it's states electrical harness not included what's all that about
As long as it is the clock on one of the listed boilers, it will replace the existing one. You will not need a new harness it will fit the existing one.
Would this work as timer for a swimming pool pump system (not combi)? Currently have a DIEHL T85 MIII type 880 230v which is now not working.
Yes it will.

I'm afraid it is not suitable for your boiler. I would suggest a programmable thermostat as your best option.

I'm afraid not.
Hi There, Would this fit an Alpha InTec 24X combie? Also, can you please confirm if this will require a wiring harness? Many thanks

Hello will this fit Heatline Sargon 30. many thanks. Keith
No, I'm afraid not. I would recommend a programmable thermostat instead as the timer for that boiler is very expensive.

No it won't. It would be cheaper to fit a programmable room stat.

No. The Heatline timer is quite expensive. It is best to fit a programmable thermostat instead.

No it wont.
I have a worcester R25& 30 combi boiler the timer looks similar to this one will this one fit? or do you have one in stock that will ? Derek
This one is not suitable for your boiler. The timer for you boiler is very expensive, so I would recommend changing your room thermostat for a programmable thermostat instead.

As long as it is a Optima, and not a Optima HE, then it will fit.
Would this timer fit a Ariston 47-116-16 bolier please?
