HVAC Wiring
Use the table below when making connections between the thermostat and an HVAC system. The type of HVAC
system installed determines which wires are connected and in some installations, the power wires are the only wires
required.
1-Wire Smart Sensor
An external temperature/humidity flush mount one wire compliant smart sensor can be purchased separately. This
sensor can be used in place of the internal temperature/humidity sensor or used along with the internal sensor to
calculate and display an average reading of the temperature and humidity in a room or space. Refer to the diagram
below when making connections.
10K Thermistor
Included in the box is a 10KΩ thermistor type temperature sensor. The CLI-W210x includes two thermistor ports
labeled RS1 and RS2 for this type of sensor. Like the smart sensor described above, this sensor can replace the
onboard temperature sensor or can be used to calculate an average reading of the temperature in a room or space.
The 10K sensors do NOT observe any polarity. Refer to the diagram below when making connections for 10K type
sensors or thermistors.
