Quick Start

Your ThermaViewer can be installed and operating in minutes. Factory defaults are set to be used
with a refrigerator (21oF. min., 41oF. ref., 70oF. max.). If you are installing a ThermaViewer on an
appliance other that a refrigerator, additional set up will be required (see page 27).
Important: If your ThermaViewer came equipped with the nine-volt battery pre-installed, you may
skip step one.
Once you have unpacked all ThermaViewer components, follow the simple steps below:
1. Install the nine volt battery.
Slide the battery cover on the top of the ThermaViewer forward.
Retrieve the battery wiring harness and attach the connector to the battery.
Insert the battery into the unit and reinstall the battery cover.
2. Attach the probe.
Insert the probe cable into port one on the right side of the unit (see illustration on page nine).
Attach the thermal probe to the other end of the cable.
3. Position the probe.
Attach probe to appliance wall. For best results, the probe should be positioned away from the
door toward the back of the unit approximately one-third of the way down from the ceiling.
Tape or permanently affix probe cable to the inside wall of the appliance. In larger units, it may
be desirable to install a second probe near the door to monitor temperature spikes due to door
usage.
4. Connect power supply
Attach the power cord and insert the plug into a 120 volt power source.

Installation

Some advanced preparation, prior to installation, can assure you of many years of reliable and
accurate service. Here are a few installation tips:
1. Planning
To ensure adequate cable length, measure the distance from the desired ThermaViewer location
to the ideal temperature probe location. Be sure to consider the routing of cable around door
jambs and dressing the cable around obstacles. A 120 VAC power source is required at the
desired ThermaViewer location.
2. Temperature Probes and Cables
Probes and cables may be temporarily affixed to the appliance wall with tape or permanently
affixed. For best results, the probe should be positioned away from the door to minimize
temperature spikes. Ideal probe location is in the back of the unit approximately one-third of
the way down from the ceiling. Tape or permanently affix probe cable to the inside wall of the
appliance. In larger units, it may be desirable to install a second probe near the door to
monitor temperature spikes due to door usage.
3. PC interface Cable
The ten-foot cable with nine-pin (D9) connector on one end and a stereo plug on the other
facilitates easy downloading of data to a computer. The nine-pin D9 connector is compatible
with a computer serial port. The stereo plug connector is plugged into the ThermaViewer. If
the cable is too short to reach a computer, the ThermaViewer may be temporarily removed
from the wall and carried to the PC location. Prior to removing the unit from the wall, be sure
the nine-volt battery is in place to back up the power source. To prolong battery life and to
ensure an uninterrupted download, take the ThermaViewer power cord to the PC location with
you and plug it into a nearby 120 VAC power source.
Power, Thermal, and Data Connections

1. PC Interface
PC cable output for downloading data.
2. Thermal Probe One
Jack for thermal probe cable number one.
3. Thermal Probe Two
Jack for thermal probe cable number two.
4. Power Receptacle
The power cord (wall transformer) plugs into this 12 VAC/500mA receptacle.
5. Reset Switch
The reset switch may be actuated by using a straightened-out paper clip.
6. Contrast Control
The contrast control for the LCD may be adjusted using a small flat bladed screwdriver.
7. Relay
The plug connects to a 15A/50V AC/DC passive relay. The relay closes and the speaker emits
an alert buzzer whenever the user-defined preset conditions are met. The set criteria can be
established for either probe in the probe menus.
