3. Service mode is active – Refer to the WS18/WP18 Technical Manual
4. The appliance is recovering from a first ignition failure – duration 2 minutes
The appliance will proceed to start-up if:
•
None of the 4 conditions listed above are present AND
•
Freeze Risk mode is active (Refer to Table 5 on Page 17) AND
•
The flow temperature is below trigger temperature (Refer to Table 8 on Page 60)
OR
•
None of the 4 conditions listed above are present AND
•
Holiday mode is disabled (Refer to Page 18)
•
There is a switched live signal e.g. from a timeclock or thermostat

Start-up of the appliance begins with System Check mode and proceeds through Preload,
Ignition and Stabilisation modes in accordance with Table 4 on Page 14. On completion of
Stabilisation the appliance will proceed to the Shutdown sequence (Figure 18) if the calculated
heat demand is less than 5%, otherwise the appliance will proceed to the Modulation sequence
(Figure 17) by selecting Powerband 1, Powerband 2 or Powerband 3 depending on the
difference between flow temperature setpoint and the actual flow temperature.
