Program Parameters

P1 -- Stage Sensor

The combination of sensors used to determine whether that
stage should be on or off.

1 = Stage uses sensor 1
2 = Stage uses sensor 2
3 = Stage uses an average of both sensors 1 & 2

P2 -- Stage Mode

Heat, Cool Negative, etc. This setting determines when the
stage is allowed to run, and how the stage will run.

1 = Heat Mode
2 = Cool Stir Mode
3 = Cool Negative Mode
4 = Cool Negative Tunnel Mode
5 = Cool Tunnel Mode

P3 -- Stage on Timer

Any cool stage can be placed on the system timer. This timer is
settable to 5 or 10 minutes. Any stage on a timer will run for
the system runtime percentage. (Example: 30% runtime of 10
minutes = 3 minutes out of each ten.)

0 = No Timer
1 = Standard Timer
2 = Cool Timer (Stage 5 and variable speed stages

only.)

P4 -- Onpoint

The temperature at which a stage will turn on.

P5 -- Offpoint

The temperature at which a stage will turn off.

Maximum On Point

The temperature at which a variable speed fan stage will run at
full speed. This is set as the stage On Point (P4).

Minimum On Point

The temperature at which a variable speed fan will run
continuously at its minimum speed. Any temperature increase
from that point will cause the speed to increase. This is set as
the stage Off Point (P5).

P10 – Minimum Runtime

Percentage

If temperature is below the OffPoint, the percent of the system
timer that the fan will run at it’s minimum speed.

P11 -- Motor Curve

Different manufacturers’ motors speeds vary at different rates.
For this reason, it is necessary to make calculations based on
the fan manufacturer.

0 = Hired-Hand

P20 -- Cycle Time

The length of time in minutes between the start of one curtain
position adjustment, and the start of the next curtain position
adjustment. (Cycle time of 3 means that the curtain will move
up or down (or remain stationary) depending upon temperature
for its runtime once every 3 minutes.)
