Extreme Temperature/Open Or Short Circuit Condition

If the measured outside temperature is more than 60°C (140°F) or the ATS sense circuit is shorted to ground, the temp display will be 60°C (140°F) to indicate a short circuit condition.

If the measured outside temperature is less than -45°C (-49°F) or the ATS sense circuit is open, the temp display will be -45°C (-49°F) to indicate an open circuit condition.
