current temperature and also logs the maximum and minimum
temperatures experienced. With the use of an Optional momentary
switch the min. / max. Temperatures can be displayed at the touch
of a button and reset if required. (Switch sold separately) A 9 Volt
battery can supply backup power for temperature readings when
there is a blackout. (Battery bracket and harness sold separately)

The instrument is equipped with fast-on type spade terminals with
probe connections separated from the power supply connections.
To install the instrument proceed as follow:
1. Attach .250 inch Fast-on connectors to the wires for the interior
light and the wires connecting the switches.
2. Wire the switch according to the drawing Fig. 1.
3. Place the probe where it has to measure the temperature. Be
sure to leave slack so as to have some strain relief. Probe bulb
should have the end up vertically or on at least a slight angle to
try to prevent water intrusion into the sensor. Were a sharp
bend is required try to loop the probe wire in a 1 ½ “circle.
4. Connect the probe terminals to the two small (.110 inch) faston connectors as indicated.
