If the vent position reading is different from where the computer thinks the vent is by more than a certain
percentage that you select, then an alarm is triggered assuming that the reading has persisted for the
length of time that you also must enter. This is an alarm that is particularly useful if a worker were to
leave the vent open from using the manual switches. When the alarm triggers both the high and low
alarm relays are turned on and both the high and low temp LED lights are on.

Auto-calibrate
Off
The purpose for the
Auto-calibrate
mode is to establish the open-close run time of the vent between the
open and close positions of the position sensors. When the
Auto-calibrate
option is switched to
ON
, this
mode is engaged and the vent will automatically go through the open-close routine and the runtime
between the position sensor positions will be saved in memory.

Active Cool Ovrides
This is an override screen that becomes engaged when the Active Cooling mode is engaged. For
example, if the greenhouse has vents and a chilled water cooling system, it will be important that the
vents are closed when the chilled water valves are turned on. This screen is where you program the
vent position when the Active Cool mode is engaged.
Curtain Programming
Shade Control
Note:
This equipment type requires 2 consecutive channels 1&2, 3&4, etc. The first channel (odd numbered)
must
be wired to OPEN the valve, and the other (even numbered) to CLOSE it.
In programming your curtain for shading you will first set a close and open time. It is during this window of time
that you permit or enable the curtain to be controlled for shading purposes.
