2 wire and 4-7 wire control box package used when adding a/c or a heat pump to a Nordyne E1EH, E2EH, E1EB, E2EB & E2BH electric furnaces that are not already a/c equipped. Also found on many M1 furnaces. For a replacement circuit board, order part number 624625. This will replace the obsolete 2-wire control box 902986 including control board 624567. When replacing a 2-wire system, you will need to order a 903992 4-5 wire thermostat. If you only have 2 thermostat wires running from the furnace to the thermostat, you will need to update that with a 4-7 wire cable. Box contains a circuit board and a variety of adapter harnesses. Includes mounting brackets. Box measures approximately 6.5" x 4" x 1.5".
