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.

Table 18. Termination module post-installation checklist

Circuit	Mandatory	Test	Actual value
	wiring
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 Ω 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 Ω 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 Ω 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.
