Outdoor Sensor (small commercial split systems
only)
An outdoor temperature sensor (X2658) is required
for balance points and Humiditrol
®
unit operations.
Users has three options to select from (under
Installer Settings > sensor settings > outdoor
sensor):
S Option 1 is using a outdoor temperature
sensor (X2658) (default). Sensor connects to
To and Tc terminals on the thermostat.
S Option 2 is using a discharge air temperature
sensor (19L22). Connects to To and Tc
terminals on thermostat. This sensor is a
non-adjustable duct mount temperature
sensor.
NOTE - The outdoor sensors use standard
non-shielded thermostat wiring; it may be wired
using two wires of a multiple wire cable.
Indoor Sensors (remote temperature room
sensor)
This thermostat can support one to five remote
indoor temperature sensors. Users have three
options to select from under Installer Settings >
sensor settings > indoor sensor:
S Option 1 is remote 10k (47W37)
S Option 2 is remote 20k (47W36)
S Option 3 is internal (default)
NOTE: Both external sensors are purchase
separately. Wiring examples for up to five sensors
are illustrated in figure 6 on page 11. All examples
shown result in Option 2, 20k setting.
For detail installation requirements and procedure,
refer to the instructions provided with either kit.
Thermostat terminals Ti and Tc are used for indoor
sensor(s).
NOTE - All remote sensors use standard
non-shielded thermostat wiring; outdoor sensors
may be wired using two wires of a multiple wire
cable.
NOTE - Outdoor and indoor sensor wire runs
should not exceed 300 feet (100m).
NOTE: The discharge air sensor is for monitoring
and display only. There is no control based on input
from this sensor.
