Program Parameters
P1 -- Stage Sensor The combination of sensors used to determine whether that
stage should be on or off.
10 = Stage uses sensor 1
02 = Stage uses sensor 2
12 = 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
P4 -- Onpoint The temperature at which a stage will turn on.
P5 -- Offpoint The temperature at which a stage will turn off.
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.)
P21 -- Run Time The number of seconds that the curtain machine will run
opening or closing at the beginning of each curtain cycle (See
Cycle Time).
P22 -- Initial Run Time Number of seconds to run on the first drop from closed. This is
to be sure that you have cleared the top of the opening. This
setting only applies when the controller senses that the curtain
is closed when it begins its run.
P23 -- Degrees above
target (Unit 1)
Many times it is more cost effective to bring a slightly high
temperature back into range with a fan. This setting allows you
to specify a number of degrees above the target temperature
that the curtain will allow before trying to open.
