CO
2
Sensor
Two CO
2
sensors are used in conjunction with the
“DE-
MAND VENTILATION”
option. In
“DEMAND VEN-
TILATION”
the Unit Control monitors the CO
2
level
of the outdoor air and the CO
2
level in the conditioned
space and varies the amount of ventilation air based on
the relationship between these two values.
gives the VDC output for a given CO
2
level.
Furnace Status Input
The Unit Controller monitors the operation of the
Staged Gas Heat section and displays the status through
the STATUS screen of the User Interface. The opera-
tion of each of the gas heat sections is monitored by a
multiplexer installed in the gas heat section. When a
gas heat section is energized, it sends a 24-volt signal
to the multiplexer. The multiplexer takes the five ON /
OFF inputs and converts them into a 0 to 5VDC signal
that is sent to the Unit Controller. The Unit Control-
ler then decodes this analog input and displays the fur-
nace section status.
shows the
relationship between the DC voltage and the furnace
operation status.

Humidity Sensors
The humidity sensor outputs a 0 to 5VDC in response to
the relative humidity sensed. An outdoor air humidity
sensor is used whenever the economizer is configured
for single or dual enthalpy. A return air humidity sensor
is used whenever the economizer is configured for dual
enthalpy. A humidity sensor is also used to monitor the
humidity in the space between the slab and raised floor
system used for FlexSys applications.
gives the relationship between the voltage output
of the humidity sensor and the % relative humidity.
