4.2 Loading the sets of parameters
Up to 6 sets of custom parameters can be selected on the controller, after
having been loaded using the VPM programming tool (Visual Parameter
Manager, see appendix 1) and the programming key.
Procedure:
• power down the controller;
• power up while holding Prg/mute;
• the display will show the  rst set: bn0;
• press UP/DOWN to select set bn1 to bn6. For example, select bn2;
• press Set to con rm the selected set: the controller will load the set
of parameters called bn2 and then will return to the standard display.

Tab. 4.j
Note: bn0 is the default set of parameters on the controller, i.e. the
default con guration. When one of sets bn1 to bn6 is loaded, bn0 is
overwritten with the new set and is consequently erased.
4.3 Preparing for operation
Once having completed the installation, con guration and programming
procedures, before starting the controller, check that:
• the wiring has been completed correctly;
• the programming logic is suitable for controlling the unit and the
system being managed;
• if the controller is  tted with RTC (clock), set the current time and date,
and the on and o times for the light/auxiliary output;
• set the standard display;
• set the “probe type” parameter based on the probe available and the
type of control (NTC, NTC-HT, PTC); note that the controllers that use
PTC probes may have di erent part numbers from those that only use
NTC probes;
• set the type of defrost: heater or hot gas;
• set the temperature unit of measure (°C or °F);
• the protection functions (delay at start-up, rotation, minimum on and
o times for the outputs) are active.
Note: all the alarms with manual reset can be reset by pressing the
Prg and UP buttons together for more than 5 seconds. See the chapter on
“Alarms”.
