Zone Humidity Sensor	Check Sensor Input	Check the AC voltage supply to the
		Sensor output board, inside the door of

		Volts AC
	Check Sensor Output	Check the DC output voltage from the
		sensor output board, inside the door of
		the TCS22. The voltage should be
		between 1 and 5 Volts DC. The Output
		voltage will correspond with the
		Humidity according to Table 7.
OutDoor Temperature Sensor	Check Sensor Output	Determine the Outdoor Temperature.
		Remove plug in connector J1 from the
		TCS22 controller. With a Digital VOM,
		check the resistance between pins #13
		and #14 in the plug. The resistance will
		correspond with the Temperature of the
		sensor according to Table 6.
OutDoor Humidity Sensor	Check Sensor Input	Check the AC voltage supply to the
