Control4 Wireless Thermostat Installation Guide 2
Sample Wiring Configurations
WARNING! Do not install LINE VOLTAGE wires to a LOW
VOLTAGE wire.
IMPORTANT! When utilizing power stealing, we recommend
installing the included 270 Ohm bypass resistor on the HVAC
system to minimize any potential side-effects. For additional
information on power stealing and installing the bypass resistor, visit
control4.com.
IMPORTANT! Do not install any REMOTE TEMPERATURE
SENSORS to the TS terminals other than supported external
temperature sensors (Flush Mount Remote Temperature Sensor,
Aprilaire™ Model 8051; or Duct/Outdoor Remote Temperature
Sensor, Aprilaire Model 8052). For installation instructions, see
Aprilaire documentation.
IMPORTANT! Install the U-shaped Terminal jumper wire between
RC and RH for a single stage system.
