10. OTHER FEATURES OF THE UNIVERSAL-R
As well as the main digital display, there are some small icons on
the front panel. These are used to monitor the loads controlled by
the instrument. Each icon function is described in the following
table.
Table 7: display signalling description
ICON FUNCTION MEANING
ON Light (AUX) output enabled.
ON Cooling enabled.
FLASHING Anti-short cycle delay in progress.
ON Fan enabled.
FLASHING Delay time on fan activation is running (Fnd > 0)
ON Defrost in progress.
FLASHING Drip time in progress (Fdt > 0) or delay on start defrosting is running (dSd > 0).
ON Auxiliary output activated.
ON Energy Saving activated.
ON Thermostat override enabled.
ON
ALARM signal: when in programming mode and in Pr2 level, this icon lights up notifying this parameter is also
accessible in the Pr1 level.
ON All measurement units are in Celsius degrees.
FLASHING Programming mode.
ON All measurement units are in Fahrenheit degrees.
FLASHING Programming mode.
11. THERMOSTAT OVERRIDE ( not available when parameter tC = 1 or 7 )
For rapid chilling or freezing, the thermostat can be overridden by pressing the UP button until the icon lights up. The compressor will
run in continuous mode, irrespective of temperature, for the time period set in parameter CCt. Normal operation will then resume
automatically. The cycle can also be terminated manually by pressing the UP button again for about 3 seconds.
12. DEFROST TYPES
tC parameter value Action
1 or 7 No defrost
2 Off cycle defrost by timer
3, 4, 5 or 6 Forced type of defrost: Electrical or Hot Gas
- tdF = 0: defrost is electrical;
- tdF = 1: defrost is by hot gas.
13. EVAPORATOR FAN CONTROL (only when parameter tC = 5 or 6)
The fan control mode is selected by means of the “FnC” parameter:
FnC parameter Action
0 Fans will cycle ON and OFF with the compressor and be off during defrost cycle.
1 Fans will run continuously, but be off during defrost cycle.
2 Will switch ON and OFF with the compressor and be on during defrost cycle (*).
3 Fans will run continuously and be on during defrost cycle (*).
(*) Note: Fans will stop if the temperature value set in parameter “FSt” is exceeded.
