Digital Controller Only:
Includes Only the Digital controller (no sensors or float stem)

The digital controller utilizes a pre-programmed chip that is upgradeable as control improvements are developed. In addition, the digital controller and its related sensors can be retrofitted to almost all existing GARN WHS units with minor alterations dating back to 1990. This controller is a significant improvement over the current timer controller that it replaces. The new digital controller was developed to perform the following functions:

  • Eliminate requiring the GARN WHS user to set the induced draft blower timer based on an estimate of fuel load size, wood species or estimated moisture content.
  • Increase efficiency by eliminating blower operation beyond the termination of combustion.
  • Provide a digital readout of flue gas and thermal storage temperatures.
  • Provide a digital readout of the following additional temperatures: outdoor, hot water supply and hot water return.
  • Terminate blower operation upon unexpected thermal storage water loss.
  • Display the duration of the burn (hrs & minutes) following termination of combustion.
