1 GENERAL
1.1 Description
The air handling units (AHU) contain various programmable application controls providing
the user with the widest range of solutions and combinations which can be modified
according to construction requirements, including the destination in which the plant subject is
installed. The possible configurations vary from the simple use of one coil (utilized for
seasonal heating and cooling) to the most complete solution which includes up to three coils
(for preheating, cooling and dehumidifying, and post-heating) plus a dehumidifier,
recuperator, free-cooling function, shutter controls and the fan pickup and delivery controls.
The AHU are widely configurable with built in sectional components to satisfy any user
installation requirement. The primary objective for each solution is to ensure the well being
of the environment, including air quality control and thermoigometric well being.
The optimal summer temperature is between 24-26°C and 40-60%UR; in winter between 1822°C
40-60%UR.
This application manages AHU with a single coil which is utlilized for heating during the
winter and cooling during the summer. Environmental conditions are controlled from the
central thermal and are reliant on the pre-selection of hot and cold fluids sent by the coil.
The various control functions include:
- Single coil for cooling/heating management
- Manage up to 3 coils (heating, cooling, post-heating)
- Manage up to 3 stages of resistance for the post-heating
- Controlling humidifier - On/Off and modulating
- Controlling dehumidifier
- Controlling external air shutters for free-cooling and free-heating in temperature
- Controlling external air shutters for free-cooling and free-heating heat exchanger
- Controlling external air shutters for air quality
- Manage heat recuperation (cross-flow, at single coil, rotating)
- Manage heating and cooling pumps
- Fan Delivery/Pickup Management - On/Off and at inverter
- Variation Set Point from digital input and supervisor and nocturnal time zone
- Changing modes of functionalilty from digital input and supervisor
- Seasonal Operation - Winter/Summer
- Alarm history
- Navigational User interface divided into four main levels (User, Maintenance
Operator, Installation Operator, and Constructor) each level protected by a different
password.
- Paramater upload/download using EVKEY.

4.1 Display and keyboard
Application requires an interface incorporated into the controller (later referred to as
built-in) with an alfanumeric display containing 4 x 20 characters and various keys and
dedicated led.
4.1.1 Buit-in interface
The built-in interface is directly integrated into the controller.
The keyboard contains four keys which are used to navigate pages, modify parameters and/or
values by performing the following functions:
- and (UP and DOWN): these keys modify parameters; otherwise, used to
move cursor.
- (ENTER): used to confirm a value when editing; otherwise, it enters a command
associated to the text where the cursor is currently positioned. If viewing an alarm
page press and hold ENTER key down for about 2 seconds allowing for the alarm to
reset. When viewing an alarm page, with each key pressure, all active alarms are run.
- (ESC): used to cancel a value when editing; otherwise, it requests the default
page associated with the current page in view. If pressed down and held for about 2
seconds, the ESC key enables switching the machine ON and OFF.
Additionally, 2 LED’s are presented:
- : indicates the presence or absence of alarms.

4.2.7 Password
Within each menu (excluding the clock and history menus) is an associated level that has
conditional access. Each level has an associated password which permits access to the
functions within a particular menu. Once the password is typed in, the protected functions
will become accessible to the user. Typing in the correct password will have the following
two effects:
⋅ permits access to the correllated level
⋅ permits access to sub-levels
Each password for each level can be modified from within that level or from a higher level.
For example, all passwords within the constructor level can be modified by levels below the
contructor level.
The following is an example of the password page appearing in the contructor menu:
The range of acceptable values for the password is: -999 / 9999.
If no further action is required in the current page, after a period of 4 minutes, the password
insterted will expire thus requiring a new password to be insterted.
4.2.8 Main OFF page
The main OFF page displays the reason for which the unit is turned off.
When the “Unita’ OFF da alarm” (OFF from alarm) is on, it can be shut down completely by
