Adjusting Unit Rotation Parameters
Heating
When the wall units are connected to the LV, the heat
strips are commanded off and on by the LV. This allows
the supervisory controller to match the required load
of the shelter using all of the available equipment
installed on the shelter.
To adjust the heating setpoint:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
3. Press UP or DOWN keys to scroll to Sys Config ;
press ENTER key.
4. Press UP or DOWN keys to scroll to Unit Setup
(A1) ; press ENTER key.
5. Press ENTER key to scroll to Heating (see Figure
2.6 on page 34).
6. Press UP or DOWN keys to adjust value.
7. Press ENTER key to save.
8. Press the ESCAPE key several times to return to
Main Menu screen.
The LV monitors the space temperature and compares
the value to the space heating setpoint. The system will
compare how far above or below the space temperature
is when compared to the heating setpoint. The LV will
also consider how long the shelter temperature has
been above or below the setpoint. Using these two
considerations, the controller will generate a heating
demand. The heating demand is a value between 0 and
100%. 0% represents no heating demand and 100%
representing full heating demand.
The system will consider all of the available heating
stages and distribute the number of stages across
the heating demand range. As the demand rises, the
system will stage on equipment every 2 minutes. As the
demand lowers, the system will stage off equipment
every 2 minutes.
The system will stage the equipment on in the order
shown in Table 2.3.
The system is also capable of rotating the order
in which the units are brought on. This is done to
distribute the equipment run time to each unit. This
prevents one unit from providing all of the heating
for the shelter and shortening the lifespan of the wall
unit. The system is set to switch the unit staging order
every 7 days from the factory. This timeframe can be
changed if desired by the end user. In addition to the
time-based auto rotation, the system can be manually
rotated on site for troubleshooting purposes.
To view the lead unit, turn the rotation on/off, change
the number of days between rotations or manually
rotate the units:
1. Press MENU key to go to the Main Menu screen.
2. Press UP or DOWN keys and ENTER key to enter
USER password 2000.
3. Press UP or DOWN keys to scroll to Sys Config ;
press ENTER key.
4. Press UP or DOWN keys to scroll to Unit Rotation
(A2) ; press ENTER key.
5. Press ENTER key to scroll to Time Based (see
Figure 2.7).
6. Press UP or DOWN key to change the value from
ON to OFF .
7. Press ENTER key to save the value and move
cursor to Num. of Days .
8. Press UP or DOWN keys to change the value.
9. Press ENTER key to save the value and move

11. Press ENTER key to save.
Humidity Control
The LV will monitor the indoor humidity of the space
and compare the value to the indoor humidity lower
and upper setpoints.
