ELECTRIC MODE: Unit may be fired with wood, but it will also use electric for heating if available. If off- peak heating is available it will heat the unit according to the dial switch set point.
WOOD MODE: Unit must be fired with wood. The electric heating elements are disabled.
The digital controller can operate in Wood mode and Electric/Wood mode. In the Wood mode, the controller allows the operator to fire the GARN unit with wood and will NOT turn the electric elements on to regulate the tank temperature. In the Electric/Wood mode, the operator can still fire the GARN unit with wood, but, in addition, the controller will turn on the electric elements if the following conditions are met:
1. A utility signal tells the controller that electricity is available
AND
2. The tank temperature is below the setpoint temperature
