Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
CH Demand
Selector switch set to DHW/CH
CH temperature control set to MAX
Preheat switched OFF
Attach temperature probes to flow and return pipes
CH temperature control set to MAX
Preheat switched OFF
Attach temperature probes to flow and return pipes
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Allow the appliance to ignite and run for central heating.
Observe the flow and differential temperatures.
At approximately 80°C flow temperature the boiler should shut down, without L1(overheat) fault code appearing, during this time the differential temperature should not exceed 30°C.
Note.
1. To speed up this test, reduce the heating circuit by turning off some radiators.
2. If a fault code other than L1 appears CLICK HERE.
