Controller for 2 kW, 5 kW, 8 kW heaters

This DC5V thermostat switch manages diesel air heaters rated at 2 kW, 5 kW and 8 kW. It suits RV owners and mobile workshops that need reliable cabin warmth. The unit operates from minus 30 to 40 Celsius. Its ABS housing measures 81 by 63 by 18 mm.

Remote control and LCD display

A handheld 433 mHz remote lets you adjust settings from a distance. The built-in LCD shows current status at a glance. Both accessories draw power from the same 5 V supply. No extra wiring harnesses or software packages are included in the box.

Simple three-piece installation

Mount the controller, pair the remote and connect the 5 V feed — only three steps. The manual covers basic wiring but assumes familiarity with heater control lines. Incorrect polarity on the DC input is the most common error. The compact 3.19 by 2.48 inch footprint fits tight dash spaces.

Questions about this item

Will the ABS housing or LCD display degrade after long exposure to the -30 to 40 °C operating range?

The controller is built from ABS plastic rated for continuous operation between -30 °C and 40 °C, so the housing and display are designed to withstand those extremes without scheduled replacement.

What limits continuous operation first — the DC5V supply or the 433 MHz remote link?

The unit draws power from a DC5V source, so the first practical limit under sustained use is the stability of that 5 V supply; the 433 MHz receiver remains active as long as voltage is present.

Does the controller generate noticeable heat or noise when running all day in a parked vehicle?

The controller itself consumes only DC5V and has no moving parts, so it produces negligible heat and no audible noise during continuous operation.
