66 NO CH BUT DHW OK

Set for Winter operation (see Frame 21)

Is the boiler set for Winter operation?

yes

Are the external controls calling for Heat?

Ensure that the Timer and Room

Thermostat are calling for heat

yes

Are the Radiator Valves open?

Open the Radiator Valves

yes

Is an OpenTherm device connected to the boiler (note

that the Ideal Prog Room Stat is an OpenTherm device)?

Does the wiring from the boiler to the

OpenTherm device have continuity?

yes

Rectify wiring from boiler

to OpenTherm device

Is there 230Vac at (A)?

There is no voltage from the external

controls. This is not a boiler fault.

Ensure voltage is supplied to the boiler

by correcting external wiring

yes

Is there 230Vac at (B)?

Check wiring from PCB to (B)

yes

Does wiring to external CH Pump have continuity and is

wired to the correct connections?

Rectify wiring to external CH pump

yes

Is the CH pump stuck

Replace the CH pump

yes

Free the pump
