4. Completing Installation

Once all the installation steps have been completed, and system verification and run test results were satisfactory,
the installation can now be considered “complete.” The Bard-Link

PLC lead/lag controller has been pre-

programmed with what is widely considered to be the most efficient operating parameters—see Table 1.3 on page
40. Further information on exact sequence of operation and advanced programming changes can be found in the
Service section of this manual.

Cool Weather Operation (Free Cooling Available):

Stage 1 Cooling

78°F – Lead unit free-cooling damper opens (Se Cooling Stage 1 Differential)

Stage 2 Cooling

79°F – Lag unit free-cooling damper opens (+ Cooling Stage 2 Differential)

Stage 3 Cooling

81°F – Lead unit compressor, damper will stay open if conditions are conducive for free cooling
(+ Cooling Stage 3 Differential)

Stage 4 Cooling

83°F – Lag unit compressor, damper will stay open if conditions are conducive for free cooling

(+ Cooling Stage 4 Differential)

Hi-Temp Alarm #1 85°F
Hi-Temp Alarm #2 90°F – Emergency ventilation initiates, both dampers open, both blowers run

75°F – All cooling stops, blowers stop (Setpoint -2°F)

Stage 1 Heating

58°F – Lead unit heat strip activates

Stage 2 Heating

56°F – Lag unit heat strip activates

Low-Temp Alarm

45°F

62°F – All heating stops, blowers stop

Warm Weather Operation (No Free Cooling Available):

Stage 1 Cooling

78°F – Lead unit compressor (Se Cooling Stage 1 Differential)

Stage 2 Cooling

83°F – Lag unit compressor (+ Cooling Stage 2, Stage 3 and Stage 4 Differentials)

Hi-Temp Alarm #1 85°F
Hi-Temp Alarm #2 90°F – Emergency ventilation initiates, both dampers open, both blowers run

75°F – All cooling stops, blowers stop (Setpoint -2°F)

3. Conduct Run Test

Execute a run test on each unit to verify the equipment
is functioning correctly.
On Bard-Link

controller, navigate to the Run Test

screen (Figure 1.32).

FIGURE 1.32

Executing Run Test

1) From the Main Menu screen, press the UP

or DOWN key to get to Technician menu, hit
ENTER key. (If not already on Main Menu
screen, press MENU key to get to Main Menu.)

2) Use Up or DOWN key to get to Service menu,

press ENTER key.

3) Use Up or DOWN key to get to Control menu,

press ENTER key.

4) Cursor will be flashing in upper left corner of

screen. Press ENTER key to scroll to U1 Run
Test.

5) Press UP key to change 'No" on screen to

"Yes". Unit 1 will begin the run test.

Note:

While initiating the run test on each

unit, use this opportunity to appropriately label

each system as “Unit 1” or “Unit 2.”

6) After the Unit 1 run test ends, press ENTER

key to scroll to U2 Run Test.

7) Press UP key to change 'No" on screen to

"Yes". Unit 2 will begin the run test.
