Indoor Sensor for RV Climate Control

The Tekmar 077 Indoor Sensor monitors interior temperature for RV heating and air-conditioning systems. It provides the data a thermostat needs to maintain a set point. The part is designed for recreational-vehicle installations. It suits owners replacing a failed probe or adding a sensing point.

Replaces a Faulty or Missing Probe

A working sensor restores automatic temperature regulation when the original device has drifted or failed. The upgrade is worth it when the climate system cannot hold a steady temperature because of a bad reading. It also applies when a zone lacks a sensor entirely. No other components are required for the swap.

Wired Connection Limits Placement

The sensor communicates over a low-voltage wired link to the controller. Cable length and routing determine where the unit can be mounted. Long runs may need heavier gauge wire to avoid signal loss. The device does not support wireless or network protocols.

Questions about this item

Does the Tekmar 077 Indoor Sensor require a specific mounting box or surface type for installation?

The sensor is designed for indoor wall mounting; use a standard low-voltage bracket or surface-mount it directly on drywall or panelling with the supplied hardware.

What wiring step is most often missed when connecting the 077 Indoor Sensor to the controller?

The two-wire bus must be landed on the correct polarity terminals at the controller; reversing them will prevent communication even though the sensor powers up.

How often should the 077 Indoor Sensor be checked or replaced to maintain accurate temperature readings?

Tekmar recommends verifying calibration annually during the RV's pre-season service; replace the unit if readings drift more than one degree from a calibrated reference.
