Unit Description

Power Supply Board
The power supply board provides regulated DC
power to the microprocessor and interface board.
It is separate from the other boards due to
manufacturing considerations and to allow the
capability to be increased as required for future
applications.
If the LED on the power supply board is
illuminated the power supply board is functioning
normally.

Multi-Temp Option Board
The Multi-temp Option Board adds the control
functions for Zone 2 and Zone 3. The
microprocessor controls the operation of the
additional zones through the control relays on the
multi-temp option board. An LED is illuminated
when a relay is energized by the microprocessor
and has transferred its contacts to the energized
state.
The only user serviceable components on the
“multi-temp option board” are the fuses and
jumpers.
