Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Observation:
Only CH operation is affected by JP2.
JP2 not fitted.
If a jumper tag has not been inserted at JP2 on the pcb, CH operation is 2-minutes at minimum burner pressure, then 15-minutes at 75% of maximum output, there after the appliance operates on maximum output or begins to modulate until the desired temperature setting is reached, anti-cycle time delay, set at 3-minutes.
JP2 fitted.
If a jumper tag has been inserted at JP2 on the pcb, the operation at minimum burner pressure is reduced from two minutes to
30-seconds, the 15-minute operation at 75% output is cancelled and the three-minute anti-cycle is also cancelled.
