1 14Introduction

Congratulations on your purchase of the Maretron Temperature Module. Maretron has designed
and built your TMP100 to the highest standards for years of dependable and accurate service.
Maretron's TMP100 measures the temperature for up to 6 temperature probes and reports the
information over an NMEA 2000
and 2 high temperature thermocouple probes. Optional thermistor probes (-20°C to 80°C or -
4°F to 176°F) cover a wide range of applications including cabin air temperature, engine room
air temperature, refrigerator/freezer temperature, under bolt temperature (inverters, charges,
pumps, motors, etc.), tank temperatures (live well bait, hot water, etc.), and air duct
temperatures. The optional thermocouple probes (0°C to 900°C or 32° to 1652°F) are used to
measure Exhaust Gas Temperature (EGT) as part of a comprehensive fuel management
system.
The Maretron TMP100 is designed to operate within the harsh demands of the marine
environment. However, no piece of marine electronic equipment can function properly unless
installed, configured, and maintained in the correct manner. Please read carefully and follow
these instructions for installation, configuration, and usage of the Maretron TMP100 in order to
ensure optimal performance.
