The micro panel is capable of supplying a printout of
chiller conditions or fault shutdown information at any
given time. This allows operator and service personnel
to obtain data and system status with the touch of the
keypad. In addition to manual print selection, the micro
panel will provide an automatic printout whenever a
fault occurs. Detailed explanation of the print function
is given under “Print Key” located in the Keypad and
Display section.
Johnson Controls recommends the field tested WEIGH-
TRONIX model 1220 printer (or former IMP 24). This
is a compact low cost printer that is ideal for service
work and data logging.

tacting WEIGH-TRONIX for purchase information at:
