Boiler type Helix VX-200

Error code E44

Cause:

Boiler is powered by three wires, hot, neutral and ground. E44 displays when neutral wire is not neutral.

Solution:

1. Measure incomming power with volt meter. Is terminal 120VAC(L) approximately 120 VAC? Is 120 Vac (N) approximately 0 VAC? 
Yes: -> 2
No: Correct power supply to boiler

2.Verify order of pins on J2. Pin order should be: empty, black (or red), white, green. Measure volts on pins of black wire and white wire. Is wiring/pins in right order? Does black/wire have 120 VAC? Does white wire/pin have 0 VAC? 
Yes: Replace Control Module
No: Replace wire harness
