Retrofit PictureThe Retrofit Kit has everything you need to upgrade an existing 3-knob control. There is a mounting plate to cover the opening for the old 3-knob control and mount the new display (available in white or black). A remote air sensor, display cable and electrical box with Passport II circuit board are also included. The wire harness has a polarized plug which mates with the existing plug.
Details The entire assembly is grounded and protected against static interference and RF noise. The circuit board is conformably coated to provide high resistance to external damage or corrosion. Internal self-diagnostic programs provide complete electronic checks of all lights, sensors, keys and circuits. Fused circuits and M.O.V.'s (Metal Oxide Varistors) provide component and board protection. Non-volatile memory stores all user-selectable parameters indefinitely during operation or any power failure situations.
