I have a glow worm ultimate boiler and a drayton tempus 3 programmer. Need to replace programmer as only parts of the digital digits appear, making it hard to read settings. Bought a LP522, which is suppose to be compatible with the tempus 3. Took off the tempus 3 but the wiring is not as it should be. It is:
yellow/green = E
black = N
Yellow wire and Red wire = L
No wire in 1
No wire in 2
blue wire in 3
red wire in 4
Tried to keep wiring as it is, but the hw and ch lights come on but no hw or ch.
