Troubleshooting
Display shows two dashes when outdoor
temperature button is pressed.
Sensor not connected properly, shorted or open
wiring or sensor.
Control displays very high outdoor temperature.
Wires are touching (shorted together) or sensor is
damaged.
Control displays very low temperature.
Improper wiring connection to sensor or sensor is
damaged.
The sensor and the sensor field wiring can be checked by measuring the resistance at the control's
subbase with the control removed. See Table 1 for proper values.
If the resistance value is /- 5
% of Table 1 values, the sensor is good.
