AUTOTERM PU-27 OLED heater control panel
Use the AUTOTERM PU-27 to control compatible air or liquid heaters in a caravan, motorhome, campervan, boat or other mobile installation. Its OLED display is designed to remain readable in low temperatures, while the built-in temperature sensor supports temperature-based control.
Availability note: AUTOTERM has discontinued this legacy control panel. This page is retained for exact model and compatibility reference. Contact us if you need help checking current AUTOTERM control options for your heater.
Compatible AUTOTERM heaters
- Air heaters: Air 2D, Air 4D, Air 8D and Air 9D
- Liquid heaters: Flow 5 and Flow 14D
Compatibility can depend on heater generation and wiring. An older 14TC-mini or Flow 14D 12 V heater with a rectangular connector requires AUTOTERM adapter harness assembly 3795, sold separately. Check your heater model and connector before ordering.
What the PU-27 lets you do
- Start and stop the heater manually
- Control ventilation on compatible air heaters
- Set operating time and use start-up timers
- View supply voltage, current time and operating time
- See heater fault codes and software information
The available menus and controls depend on the connected heater.
