When the furnace is running profile or normal recipes, the digital inputs can be used to select
the number (0 - 15).
2.2.3 Microprocessor Board
The hub of the system is a Motorola CMOS 8-bit microprocessor. The on-board timer is
used for all the timing functions. This board has one socket housing the functional EPROM
and three sockets for the (8 Kb) memory chips. The processor board is equal for DTC and
DPC, the functional EPROM and the amount of memory chips define the function of the
processor board.
For a DTC processor board a DTC EPROM and 1 memory chip is sufficient (for a DPC
processor board a DPC EPROM and 3 memory chips are required).
