T7771A REMOTE TEMPERATURE SENSOR
Averaging Multiple Sensors
The default position for the J2 jumper is 20K ohms. When
using a single sensor, leave the jumper in this position.
For temperature averaging using a T7350 Commercial
Thermostat and multiple sensors, use the following
guidelines:
— Only one T7771 can be used.
— For the second sensor, use a T7770A3002 (which has a
10K ohm output).
— Wire the two sensors in series.
