Outdoor Reset Mode (RESET)
Outdoor reset mode is used to automatically adjust the setpoint for a wood boiler based on
outdoor temperature. The controller will automatically adjust the setpoint higher when the
outside temperature gets very cold as well as reduce the setpoint when the outdoor temperature
warms up. This reduces wood consumption and enhances comfort.
Reset_setpoint = 70 + ( ( 70 - Outside Temp ) * SLOPE / 10) - Fahrenheit
Reset_setpoint = 21 + ( ( 21 - Outside Temp ) * SLOPE / 10) - Celsius
Here is a link to a spreadsheet for comparing calculated setpoints vs outside temperature and
the slope setting:
