USE AND MAINTENANCE MANUAL
GENERAL FEATURES
For safety reasons and to simplify the operator’s work, the PLUS300 EXPERT U THR has
two programming levels; the first level is used to modify SETPOINT parameters (i.e. those
parameters that are changed frequently). The second level is for general parameter
programming of the various board work modes.
It is not possible to access the first programming level directly from the second level: you
must exit the programming mode first.

For practical purposes the following symbols are used:
• () indicates the UP key used to increase value and to force the defrost / pause;
• () indicates the DOWN key used to decrease value, to mute the alarm and to force
the air changing.

alternately).
2. Press the SET key and push one of () or () keys to modify the SET POINT value.
