Hi,
I have just installed a W/B Greenstar 18ri boiler for vented separate tank and pump system in place of a Baxi Barcelona boiler.( The installation will be inspected and certified by an approved person on completion) The installation is complete, all water pipes connected and bled, gas connected (22mm) and flu complete. No other electrical disturbancies to old system.
Mains connected @ ST1 from a fused plug and the original 4 wire cable from the original system wiring center connected @ST2 as follows Red to LP Blue to NP and Yellow to LR.
(old wires red, blue, yellow plus earth) connected the same as page 25 of installation manual
On power up (with gas isol valve open) as well as max temp demanded from hall stat and CH selected "on" at the programmer
I get the following
1/ no CH light on programmer
2/ Blue light on steady on boiler front panel
3/ no boiler light up or any sound of ignition
4/ fan operates for a second and then stops
5/ tried all positions of mode switch to no avail, however blue light goes to flashing mode in max and min settings
6/ with power on and boiler selected on I get no voltage at ST2 connector either pin LP or LR
7/ 2 amp f1 fuse is servicable
I have made the following asummtions
1/ yellow wire from service center is switched live demand?
2/ system wiring center is not getting a live feed other than from the boiler?
Any help would be very helpfull
Thanks
Barry
