3.2 Digital Control Board
The TPSD is available with an LCD or VFD digital control board as Options 550 or 551 respectively. These
options replace the LED analog control board that is standard to the TPSD. The digital control board is a more
attractive and user friendly option, with many additional features over the standard LED analog control board.
