Four ways to take control
A2409PW LCD panel
View operating information and adjust settings directly through the control panel.
Wireless remote
Operate the heater without returning to the panel, within the remote's operating range.
WiFi app
Access the heater remotely when it is connected to a suitable WiFi network and your phone has internet access.
Bluetooth app
Use your smartphone for nearby control. Connection range depends on your surroundings and obstructions.
Set timers, adjust heating levels and manage automatic start-stop through the app. Language settings and fan mode are also available.

A closer look at the control panel
The six-button panel brings ventilation, heating level, temperature mode and power controls together, with timer settings and operating information on the display.
Bluetooth and WiFi, side by side
The comparison below shows the earlier Bluetooth panel alongside the WiFi version. The WiFi version adds network-based remote access; Bluetooth remains an option for nearby control.
WiFi remote operation requires a suitable network connection and internet access on your phone. Bluetooth range varies with surroundings and obstructions.
Warmth with less manual adjustment
Choose your preferred temperature and let automatic start-stop cycle the heater as needed. When heating is not required, fan mode provides air circulation.
The aluminum heater body transfers heat to the airflow. Warm-up time and heating coverage depend on insulation, ambient temperature, installation and the size of the space.
Performance figures in the illustration depend on test conditions and are not a guaranteed warm-up time for every installation.
A separate 10L fuel tank
The split-type kit keeps the heater and diesel tank separate so you can plan component placement for your installation. Fuel use and runtime vary with heating level, automatic start-stop cycles and operating conditions.

Designed for quieter heating
The low-noise fuel pump and muffler help reduce pump and exhaust noise. The listed sound level is ≤35dB; actual noise depends on the operating setting, installation and measurement distance.

Automatic altitude compensation
The controller adjusts fuel delivery as elevation changes, reducing the need for manual adjustment during highland travel. Follow the user manual for the supported operating range and setup.

Built-in protection features
The heater includes overheat, short-circuit, overcurrent, overvoltage and reverse-connection protection.
Follow the user manual for installation, exhaust routing, ventilation and operation. Protection features do not replace correct installation and use.
Plan a setup for your space
Build a heating installation for a vehicle, RV, campervan, truck, tractor, garage, cabin, boat or camping setup, with component placement and operation suited to the location and the requirements in the user manual.
