4.3.2 Indicator Lights (Fig. 5)

The colour of the status light on the boiler control panel and

the number of times that it flashes indicates whether the boiler is

working normally, has a problem or requires servicing.

See Section 8.1. for details of the fault conditions.

Boiler Operating The light will flash orange at EVERY

heating demand. The number of flashes will correspond with the

heat output of the boiler. This is normal and does not indicate a

fault condition. During normal running illuminates green and

blinks off momentarily every seven seconds approximately to

show the boiler is running normally and supplying heat (Fig. 6).

Error When flashing green light indicates that the boiler has

detected a problem, and is attempting to resolve it. If it does not

succeed the boiler will go into fault mode and display a red light.

Defect When flashing red light indicates that the boiler has a

fault. Press the RESET button for a minimum of 5 seconds to try

and clear the fault condition.

A lock-out condition can be re-set up to 5 times within one hour

using the reset button. Any fault that occurs repeatedly should be

fully investigated and appropriate remedial actions taken by your

installer or heateam.

If there is a continuous red light, contact your installer or heateam

The lights will be OFF when there is no demand for heat.
