1.3 Additional Requirements
This controller is suitable for use with 1 1/2 ton through 6 ton Bard WallMount air-
conditioners. The Bard WallMount must be equipped with the "V" control module for proper
operation of the TCS22. Air-conditioner model numbers used with the TCS22 should contain the letter
"V" in the 15th position of the model number.
The TCS22 can be used with or without economizers. If economizers are to be used the units
should be ordered with the “D” vent option. The air-conditioner with economizer used with the TCS22
should contain the letter "D" in the 10th position of the model number.
Additionally, to utilize the Power Failure Management portion of the controller an Inverter and
battery backup system should be installed in the shelter. This provides for ventilation of the structure in
case of utility power failure, alarming of the power failure condition, and acts as an uninterruptible
power supply for the TCS22. See Figure 6.
If the inverter and battery backup system is not used disregard the power failure management
sequence later in this manual.
The power transfer relays shown in Figure 3 are field supplied items and are needed if ventilation
of the structure is required during power outages. The field supplied power transfer relays should be
sized to handle the MCA of the unit being controlled. Single phase units will require a 4 pole contactor
with 2 normally open and 2 normally closed contacts. Three phase units will require either a six pole
contactor or two 3 pole relays with 3 normally closed and three normally open contacts. Square D, D-
Line or F-Line contactors or equivalent are recommended.
If ventilation of the structure is not required during power outages these may be omitted. The
TCS22 will still dial out and alarm the power failure condition although no ventilation will be provided.
