CHARACTERISTICS
UG30/mP30 is an electronic control for full management of precision air conditioners, for both chilled water (CW-
CW/S) and direct expansion (DX-DX/S) versions with 1 or 2 compressors.
The control consists of a user interface and a power circuit, both fitted inside a single container.
The display shows the unit’s operating status and main parameters by means of symbols and alphanumeric codes
consisting of one letter and one number:
1, 2…: probe parameters;
r1, r2 …: adjustment parameters (e.g. r1 = cooling set-point);
c9, CA…: compressor management parameters;
F9, FA…: fan management parameters;
P1, P2…: alarm management parameters;
H1, H2…: general configuration parameters.
All control parameters are set in the factory according to the type of unit and configuration; programming is effected
by a hardware key or via a serial line. To change parameters, the operator may use the keyboard on the front panel.
USER or FACTORY parameters are available depending on whether they are accessible to the user or reserved for
authorised personnel.
