Utility Power Loss Alarm The LV will indicate a utility power loss alarm when the power loss input indicates that utility power to the shelter is not available. This can be accomplished in two ways. The first way is with units equipped with the inverter option; with these units, the wall unit controller will detect a power loss and communicate the event to the LV. The LV will then indicate a utility power loss alarm. The second way is with wall units that do not have the inverter option installed; with these units, 230v may be run into the LV enclosure and connected to the power loss relay. When 230v is not present at the power loss relay, the LV controller will indicate a utility power loss alarm. When the power loss alarm is no longer present from either the power loss relay in the LV or the wall units, the alarm will automatically clear. NOTE: The variable provided in the Direction column
of the Digital In Config (C1) screen (as shown in Figure 3 on page 7) displays either NO or NC. This column lists the digital signal the LV1000 will be looking for in the case of a power loss. If connected to an NO contact on the power loss relay, it will be NC if there is an event. Therefore, in this case the LV1000 must be set to look for NC. To change the power loss inputs: 1.

CONTROL OPERATION

Temperature Control
Control Value Averaging
The system requires one temperature and humidity sensor (included with LV) to operate. It allows a total of three temperatures and three humidity sensors to be connected to the LV for better representation of what is happening in the shelter. When more than one sensor is used, the value is averaged and then used for temperature control operations and humidity control operations.
Comfort Mode
The LV has a feature that allows a temporary override of the temperature control settings. When "comfort mode" is activated, the system will control to 72°F. The system will stay in this mode for 60 minutes and is intended to provide a more comfortable space for a technician during a service call or scheduled maintenance.
Emergency Vent
When the high temperature alarm 2 or the hydrogen input indicate an alarm, the system will enter emergency vent mode. The LV will communicate to each wall unit that emergency vent mode is active. The wall units will then override the damper position to 100% open and turn the blower on. These two items will stay in this state until both the high temperature alarm 2 and the hydrogen detector are no longer in an alarm state.
Cooling
When the wall units are connected to the LV, the economizer and compressor are commanded off and on by the LV. This allows the supervisory controller to consider the most effective and efficient order to bring cooling functions on using all of the available equipment installed on the shelter. At the same time, the LV will be able to match the load requirements of the shelter.
To adjust the cooling setpoint:

FIGURE 7 Adjusting Setpoints

The LV monitors the space temperature and compares the value to the space cooling setpoint. The system will compare how far above or below the space temperature is when compared to the cooling 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 cooling demand. The cooling demand is a value between 0 and 100%. 0% represents no cooling demand and 100% representing full cooling demand.
The system will consider all of the available cooling stages and distribute the number of stages across the cooling 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 on page 12.
Unit Rotation
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 cooling for the shelter and shorting the lifespan of the wall unit.
The system is set to switch the unit rotation order every 7 days from the factory. This timeframe is adjustable. In addition to the time-based auto rotation, the system can be manually rotated on site for troubleshooting purposes.
The system has two different modes for staging unit operation: FIFO (First In/First Out) or FILO (First In/ Last Out). With FIFO staging, the first unit on will be the first unit to turn off as demand decreases. In FILO staging, the first unit to turn on will be the last unit to turn off.
To view the lead unit and make adjustments to the unit rotation and staging:
1. Press MENU key to go to the 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 3 on page 14.
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.
See Unit Rotation on page 11 for information on unit rotation and staging.

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.

FIGURE 9 Adjusting Humdifiers Settings
Dehumidification The system will take several actions to limit the indoor humidity level. At 70% RH, the economizer will be disabled to prevent outdoor air from being used to cool the shelter which may have a high moisture content. This mode will remain active until the shelter humidity level is below 60% RH. The system will switch from high sensible to standard mode when the indoor humidity is above 75% RH which will slow the blower down to remove more moisture. This mode will remain active until the shelter humidity level is below 65%. If the shelter reaches 80% RH, the system will switch the units into dehumidification mode. This mode will cool the shelter down to the heating setpoint and the compressor will turn off. Then the heat strip will activate and heat it back up to the cooling setpoint, then turn off. This will continue until the indoor humidity level is below 70% RH. The economizer disable setpoint and differential (difference between disable setpoint and enable setpoint) are adjustable. The differential is limited to a minimum 10%. To adjust the dehumidify economizer disable setpoint and differential: 1. Press MENU key to go to the Main Menu screen. 2.
