General Description

General Description
The MicroTech II Applied Rooftop Unit Controller is a
microprocessor-based controller designed to provide
sophisticated control of Daikin RoofPak® applied rooftop
units. In addition to providing normal temperature, static
pressure, and ventilation control, the controller can provide
alarm monitoring and alarm-specific component shutdown if
critical system conditions occur.
The operator can access temperatures, pressures, operating
states, alarm messages, control parameters, and schedules with
an 8-key keypad and a 4-line by 20-character display. The
controller includes password protection against unauthorized
or accidental control parameter changes.
This MicroTech II controller is capable of complete,
stand-alone rooftop unit control, or it can be incorporated into
a building-wide network using an optional plug-in
communication module. Available communication modules

Component Data

The main components of the MicroTech II control system
include the main control board (MCB), one or two optional
auxiliary cooling control boards (CCB1, CCB2, or GCB1), an
optional auxiliary electric heating control board (EHB1), an
optional auxiliary energy recovery wheel control board
(ERB1), and a keypad/display. These control components are
located in the main control panel as shown in Figure 1 (smaller
units), Figure 2 (larger units), and Figure 3. These components
are interconnected by shielded multiconductor communication
cables, or in the case of the keypad/display by a six conductor
cable with an RJ-11 style modular connector. Transformers T2,
T3 and T9 supply power to the system. The following pages
contain descriptions of these components and their input and
output devices.
