Air Sensor Settings
Clean air sensors are essential to proper operation. Dip the air sensors into a cup of room temperature
water and swish around. Do not bump the sensor on the side of the cup. Shake off the water droplets
and leave to dry. The sensors read cooler during the cleaning process so only perform cleaning when
the building is empty (
or temporarily turn off the controller
). Verify the sensors are reading the correct
temperature after they dry.
Input the length of cable connecting the air sensor to the controller. The air sensor is an analog resistive device so
improper cable length settings can cause erroneous temperature readings. If you enter the proper cable length and
still get an erroneous reading, you can essentially calibrate the sensor by adding or subtracting the cable length value
entered here. Adding about 5 to 15 feet of length (the variance depends on the cable gauge) drops the air
sensor’s temperature reading by 0.1 degree Fahrenheit.

SENSOR CALIBRATION & SETTING Z1-S01
Air Sensor #01 Cable Length: 100’
Input the gauge of the cable connecting the air sensor to the controller. The air sensor is an analog resistive device so
improper cable gauge settings can cause erroneous temperature readings. Use shielded wire, 16 to 24 gauge (.5 to
1.2mm) stranded, such as Carol® AWM style 2426, to connect sensors to input channels.

For your information: You can get to the main menu in more than one way. You will use the “SYSTEM
SETUP” Hot-Key most of the time but depending on which screen you are working with in the control,
you can get to the main menu using other Hot-Keys, as exampled below. In the pages to follow other
Hot-Keys are shown their image for your convenience.

"See the Air Sensor Shared device on pages 88 - 90,
if deleting an air sensor or changing it's module and/or
channel number."
SENSOR CALIBRATION & SETTING Z1-S01
Air Sensor #01 Temperature Offset: -2.3
Input the temperature offset needed to adjust the displayed temperature readings of the sensor to the actual
temperature reading taken at the sensors location. Use this setting to correct any inaccurate reading of the sensor.
The reading can be adjusted by +15 to -15 degrees Fahrenheit. The adjusted temperature is displayed for that sensor
and is used to operate the system.
For your information: Changing the offset value by a large amount can cause temperature alarms,
depending on the amount of the offset change and the temperature alarm settings.
