Honeywell ST6400S

[Razzler]

Can anyone help...My cylinder stat blew and took out the programmer.
On inspection it looks like a simple case of replacing LK7 (it sits on the PCB and is connected to the 'Live in' pin and is positioned next to RV1) which, although cooked, looks like it may have been a resistor.
Does anyone have any idea what LK7 is on the Honeywell ST6400 programmer and it's value please?
Many thanks...Razzler

I cannot speak in relation to that unit but in electronics terms a "LK" is usually a zero ohms link!

Yes...That's what I thought (LK being Link)...I wonder why it's not just a straight link!!
