Using The Equipment Touch's Temperature And Humidity Sensors To Control Equipment - Carrier Equipment Touch Installation And Setup Manual

Using the Equipment Touch's temperature and humidity sensors to
control equipment
To set up the sensors on the Equipment Touch
Go to Setup > Touchscreen Setup > Sensor Setup.
On this screen, you can:
•
Select the temperature sensor—You can use values from the Equipment Touch's internal temperature
sensor. Or, you can wire an external (remote) thermistor to the Equipment Touch and use its temperature
value instead of the internal temperature sensor's value.
NOTE The Deg F and Deg C setting is determined by the controller's control program.
• Disable transmission of the temperature and humidity—See NOTE below.
•
Set an offset—Enter a correct temperature/humidity value to create an offset for all future values.

NOTE By default, the Equipment Touch transmits its temperature value (av: 1902, writes every 1 minute) and
relative humidity value (av: 1904, writes every 5 minutes). If the 1902 or 1904 object instance numbers are
to be used in a different manner, you can turn off the transmission of the temperature and humidity values.
See To edit touchscreen settings (page 21).
