Set Appliance State:
CH Demand
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Observation:
Monitor the fan speed.
As the appliance reaches the temperature set on the boilers thermostat does it begin to modulate (fan speed reduces)?
Note:
1. To reduce the time taken for this test some radiators can be turned off temporarily.
2. When the boiler reaches temperature and shuts down "d2" will be shown in display to indicate a delay period until the burner will re-ignite (this is not a fault code).
