If the error message is a Device Error (if “DEV” or “DEV ERR” is shown on screen),
read the address shown and go to the device with that address. That device will
have a Local Error indicating specifically what the problem is. When the problem is
corrected, the error message will automatically clear.
Access Levels
In some cases, it is not desirable to let day-to-day users view error messages. In
these cases, by lowering the access level of the thermostat or setpoint device to
‘User’ or lower, error messages cannot be seen in the View menu and the warning
symbol only appears if there is a local error or a device error caused by a critical
error on another device. If there is an error message on the system that you cannot
find on a particular thermostat, make sure that the access level on that thermostat
is set to Installer or Advanced.
Sensor Temperature Errors
If a control is unable to display a temperature due to a sensor malfunction or
communication problem, the word “Err” is displayed in place of the temperature.
This usually indicates that there is an error somewhere on the system but is not
the actual error message. Keep looking through the View menu to find the actual
error message.
