Honeywell T7335A 2002 - 1004

[mattylad]

Can anyone advise the difference between a Honeywell T7335A 2002 and a Honeywell T7335A 1004 ?

(from a Worcester 9.24e BF)

I can't find the 1004 available on the web, seems to be the 2002.

the datasheet does not appear to mention what the end number/specification is.

Also where one can be obtained.

Thank you

The 2002 is the current replacement for the 1004.

OK thank you.

Can anyone suggest a simple way to tell if this is working correctly?

I.E. what resistance it should be in normal use & what it should be if it shuts the boiler down?

Thank you.
