3 Using the Controller
The control system consists of a unit controller (UC) equipped with a set of extension modules that
implement additional features. All boards communicate via an internal peripheral bus with the UC.
The Microtech III continuously manages the information received from the various pressure and
temperature probes installed on the compressors and communicated to the unit . The UC
incorporates a program that controls the unit.
The standard HMI consists of an inbuilt display (A) with 3 buttons (B) and a push’n’roll control (C).
The keypad/display (A) consists of a 5-line by 22 character display.
The function of the three buttons (B) is described below:
Alarm status (from any page it links with the page with alarm list, alarm log and alarm
snapshot if available)
Back to Main Page
Back to the previous level (it can be the Main Page)
The push’n’roll command (C) is used to scroll between the different menu pages, settings and data
available on the HMI for the active password level. Rotating the wheel allows to navigate between
lines on a screen (page) and to increase and decrease changeable values when editing. Pushing
the wheel acts as an Enter Button and will jump from a link to the next set of parameters.
3.1 General Recommendation
Before switching on the unit read the following recommendations:
When all the operations and all the settings have been carried out, close all the switchbox
panels
The switchbox panels can only be opened by trained personnel
When the UC requires to be accessed frequently the installation of a remote interface is
strongly recommended
Evaporator, compressors and related inverters are protected from freezing by electrical
heaters. These heaters are supplied through unit main supply and temperature controlled
by thermostat or by the unit controller. Also the LCD display of the unit controller may be
damaged by extremely low temperatures. For this reason, it is strongly recommended to
never power off the unit during winter, especially in cold climates.
