Isolate Mains Power to appliance as per TOPs P4
Observation:
The appliance is fitted with a single digit display which is located on the front of the control box behind the hinged door.
The display serves two functions:
1. When showing 0, L, H, h, t, c, indicates operational status of appliance.
2. Codes other than the above indicate possible fault areas.
It is important to follow the set up procedures of the tests, i.e. start with mains power off, as when power is first applied to the appliance it carries out a self checking procedure.
This model assumes the pump has been wired into the boiler's terminal block as per manufacturer's instructions.
Using this Xsol model on an incorrectly wired appliance will lead to a misdiagnosis.
