VI. Adjusting Stages 3-6 Differentials
Differentials tell the controller when to start
stages 3-6. If the controller does not use a
fix hysteresis to stop these stages, it then
uses differential values to stop them when
the remperature decreases (Refer to the "Fan
Stage" graph). Differentials can be adjusted
from 0,3°C and 10,0°C (0,5°F and 18,0°F).
• Select the STAGES 3-6 DIFFERENTIAL
menu. The differential of stage 3 flashes on
the display, alternating with "3 diF".
• Use the adjustment buttons to set it to the
desired value.
• Press the Other Functions button to select
the differential of the next fan stage.
• Proceed in similar fashion to set the differ-
ential of stages 4 to 6 (if applicable).
VII. Adjusting the De-icing Timer
The de-icing cycle time is the period of time
separating de-icing cycles. It ranges from
1 to 720 minutes and must be greater than
the De-icing On Time. The de-icing On Time
ranges from 0 to 900 seconds.
• Select the STAGE 2 DE-ICING menu . The
de-icing cycle time is displayed, alternating
with the letters "CYCLE".
• Use the adjustment buttons to set it to the
desired value.
• Press the Other Functions button. The de-
icing On Time is displayed, alternating with
the letters "t On".
