Model MP-941/942/943/944
3-6. OPERATION AND
Setting Control to the Correct Number of Drawers
PROGRAMMING
(Continued)
The different models, MP-941, 942, 943, and 944, all use
the same control board. The boards are programmed at
the factory for the correct unit. But, should the unit show
“E06” or some drawers will not heat, the board may not
be
programmed
for
the
appropriate
unit.
The LED flashes at a fast rate for the drawer(s) not
programmed correctly.
To check the drawer programming, turn the unit off, then
back on. The display will flash the number of drawers
the unit is programmed for. If the unit is not programmed
correctly, follow these steps:
1. Turn the power switch off, then press and hold the
SET button and the drawer button, which corresponds
to
the
number
of
drawers that the unit has, and turn
unit back on, ex: MP-944=SET and number 4
button.
2.
Release
the
buttons, and now the unit should be set
up
for
use.
Pressing and holding the drawer button shows the
temperature of that drawer. If no temperature is
displayed, the unit may need to be programmed by
the
above
steps.
