Can I use this to replace a Satchwell Clamp-On Thermostat dating from about 1985? Size is about 1 3/4 inches by 3 1/2 inches. There is no model or serial number.
Yes you can. the wiring same as SA1452...same colour code for terminal connections allowing a straight swap? Thanks
Hi. Yes it is.
I am looking to replace a long serving Telecon 140LE. Is the SA2452 a suitable choice and what are its dimensions (height and width?
I'm afraid I have no information on that one. Can you email us a photo?
I currently have SA1452 clamp-on thermostat fitted - what are the options, would this one work for me?
Yes. This will be a suitable replacement.
Is the SA2452 the same phsical size as the SA1452? I have a cut out in my tamk insulation that i would like to keep the same. Many thanks
It is slightly smaller so you will not need to cut any extra insulation.
Can I use this SA2452 to replaced an SA2401 and is the wiring the same?
Yes. The terminal numbers are the same.
We have a back boiler with hot water tank Please can you tell me do you sell a satchwell thermostat types sa& pa or is there something that has replaced
If it is an ordinary copper cylinder, then this would be suitable.
Can the temperature be adjusted to start at 45 degs or more? I want to use this on the radiator system only.
It has a SPDT contact so could be wired so it starts what you want when the temperature is above the set-point.
Is this a suitable replacement for the SA1452?
Yes it is.
Does anyone have the wiring diagram for an SA2451 so i can identify each wire and correctly wire my SA2452, because i dont know what each wire is currently in my ssa2451 there are no markings only the earth!

can i use this model to replace sunvic 1452
Yes, you can.
I am considering replacing the existing SA2501 thermostat which pre-wired to a connector plug for direct assembly to the Duo valve control box. Is this still the case for the SA2452?
It is not pre-wired. So you will have to connect the old wire to the new thermostat.
Hello is this a replacement for the Satchwell SA 2451 Cylinder stat? thanks for any help you cabn give Eddy
Yes it is.
Hi, Could you confirm that this is the correct replacement for a very old silver cased Satchwell Boiler Thermostat? The one I have sits on the outside of the boiler and fixed via a metal strap. Many thanks
Please let us know the model number (or a photo) of the one you are replacing to and we will check for the correct replacement.
