Alarms and Troubleshooting

Alarms

If any alarm is triggered on the unit, the Bell icon will
flash for 10 seconds accompanied by an audible tone
alarm. After 10 seconds, the bell icon will stop flashing
and become solid and the audible tone alarm will be
silenced. If any alarm is present on the unit, the TEC-
EYE display will need to be used to find out what the
alarm is.

Troubleshooting

The th-TUNE device is only a single unit controller. It
provides a means to display basic information from the
MULTI-TEC wall-mount unit and provides a temperature
and humidity probe to better measure a room's climate.
That means that all variables and unit operation is
handled at the wall-mount unit controller, and any
troubleshooting beyond communication loss with the
th-TUNE will require the use of the TEC-EYE diagnostic
tool. In the case of a loss of communication between
th-TUNE and the wall-mount unit controller, a "Cn" will
appear in the main display area. In that case, check the
communications wiring.
