Appendix A Installation checklists

Termination module post-installation checklist

Use Table 18 to verify that the circuits connected to the termination board on the termination module are wired correctly. Record test results in the “Actual value” column.

24 Vac

 

Measure the voltage between TB1-1 and TB1-2. It must be 24 Vac

 

TB1-1,

 

nominal (19 Vac to 30 Vac).

 

TB1-2,

9

Measure the voltage between TB1-1 and TB1-3. It must be approxi-

 

TB1-3

mately the same voltage as measured between TB1-1 and TB1-2

 

 

 

The ground wire must be connected to terminal TB-3. It must be

 

 

 

tied to building or earth ground at nearest location. Measure the

 

 

 

voltage between TB1-2 and TB1-3. It must be approximately 0 V.

 

 

 

 

 

Alarm relay

 

Measure the voltage between TB1-4 and TB1-5. It must not exceed

 

TB1-4,

 

24 Vac. Jumper these two terminals. The user-supplied load should

 

TB1-5

 

now be energized and active.

 

 

 

 

 

Priority

 

There must be no voltage applied to these terminals. These termi-

 

shutdown

 

nals must be connected to dry contacts only. Measure the resis-

 

TB1-6,

 

tance between TB1-6 and TB1-7. It must be approximately 0 with

 

TB1-7

 

the user-supplied contacts in the closed position, and infinity ohms

 

 

 

with the contacts in the open position.

 

 

 

 

 

Meter input

 

There must be no voltage applied to these terminals. The terminals

 

TB1-8,

 

must be connected to dry contacts only. Measure the resistance

 

TB1-9

 

between TB1-8 and TB1-9. It must be approximately 0 with

 

 

 

demand meter contacts in the closed position, and infinity ohms

 

 

 

with the contacts in the open position.

 

 

 

 

 

Thermistor

 

There must be no voltage applied to these terminals. The cable

 

TB1-10,

 

shield must be connected to terminal TB1-12. Measure the resis-

 

TB1-11,

 

tance between TB1-10 and TB1-11.

 

TB1-12

 

Note the approximate temperature at the location of the outdoor

 

 

 

air temperature sensor.

 

 

 

 

 

 

 

Compare the resistance and temperature values to the listed val-

 

 

 

ues in Table 19 on page 71.

 

 

 

 

 

Comm

 

There must be no voltage applied to these terminals. Measure the

 

TB1-13,

9

resistance between TB1-13 and TB1-14. The resistance must be

 

TB1-14,

approximately 50 with daisy-chained wiring. This test confirms

 

TB1-15

 

the correct usage of the termination resistors as well as the conti-

 

 

 

nuity of the wire.
