3.12 Outdoor Temperature Sensor (Optional)
The Touch Controller can display the ambient (outdoor)
temperature. To enable, install a NT-1 Remote Temperature
Sensor and set the JUMPER position to "AMB" (see Diagram 23).
Connect the NT-1 to the 2-wire bus (TW1 & TW2).
The most accurate way of reading the ambient temperature is to
install the NT-1 sensor under the eaves on the south side of the
home away from potential heat sources.
