Aqua Hot or Webasto 12v Diesel Control Box / Aqua Hot – Burner Controller – WPE-300-901
The Aqua-Hot Heating System is a Hydronic Heating System (heating with hot water) that provides interior zone heating where and when it is needed, as well as a continuous, on-demand supply of domestic hot water. Both heating features are accomplished by a 12 Volt-DC powered Diesel Burner and a 120 Volt-AC powered Electric Heating Element. These two heating sources maintain the temperature of the Aqua-Hot’s antifreeze and water heating solution. In addition, the Aqua-Hot has been designed to preheat the vehicle’s engine before starting. This preheat feature provides an easy engine start-up whenever cool weather conditions are present.
The interior heating system is responsible for providing heat to the motor home’s interior to maintain the temperature at a comfortable level. For interior heating, it is the room thermostats that trigger the Aqua-Hot / Hydro-Hot’s interior heating system. When a thermostat recognizes that heat is required in a particular area, it sends a signal to the Aqua-Hot / Hydro-Hot’s electronic controller (Aqua Hot – Burner Controller – WPE-300-901) calling for heat.
Your Hydronic Heating System, whether it is an Aqua Hot, Hydro Hot, or Webasto DBW 2010 has a white label with a model number on the heater. This label can be found on the top or on the side of your Aqua Hot, Hydro Hot or Webasto Heating System.
