7. RATING MODE
In cooling mode should be set by remote control, the speed of the fan and internal temperature of 18°C; then press
for 6 times the button on the remote night (T3). After 2 consecutive beeps the compressor will start to operate at a
frequency of 43 Hz. Will be activated so that the two fans work at full speed.
To end the procedure, press standby button or automatically cease after 5 hours from setting. The same goes for
the heating mode, the only difference is to set a temperature of 30°C corresponding to an operating frequency
compressor 50Hz.
8. DIAGNOSTIC ALARMS
All alarms are reported in table. They reset automatically after 3 minutes after the alert or, alternatively, you can
turn off the machine and wait just 30 seconds. ONLY for IPM alarms, if they are activated more than 4 times by 15
minutes, the rehabilitation automatic function is turned off. Both types of alarm functions do not require as self-
diagnosis because are displayed in real time.
