th-Tune Setup Options Using the TEC-EYE

At this time, there is only one th-TUNE option, comfort
range, that can be set up using the TEC-EYE hand-held
diagnostic tool. For additional information about using
the TEC-EYE, see the latest revision of MULTI-TEC
Service Instructions manual 2100-665.

Comfort Range

This value sets the temperature range around the
setpoint where the unit will not heat or cool.
Example: If the comfort range is set to 5°F and the
setpoint is set to 72°F, heating would occur when room
temperature is below 68.5°F and cooling would occur
when room temperature is above 75.5°F.
To adjust the comfort range using the TEC-EYE:
1. Connect the TEC-EYE diagnostic tool to the control
board located in the wall unit. The TEC-EYE
connects to the control board via an RJ11 modular
phone connector.
The initial screen that will display on the TEC-EYE
is the status screen for the MULTI-TEC wall unit.
If the th-Tune has been properly connected to the
wall unit, the status screen should look like Figure
20.

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 unit controller, and any
troubleshooting beyond communication loss with the
th-Tune will require the use of the TEC-EYE display.
In the case of a loss of communication between th-
Tune and the wall unit controller, a "Cn" will appear
in the main display area. In that case, check the
communications wiring.
