d4 – Cooling air temperature drop prevention
This function is useful when the thermostat on/off conditions must be changed and a decrease in discharge air
temperature must be avoided. As a result, the perception of draughts is prevented.
• Thermostat off conditions (thermostat switched OFF when the discharge air temperature is low):
- Cooling operation (including dry operation).
- Indoor air discharge temperature <11ºC maintained for 3 minutes.
• Thermostat on conditions (thermostat switched ON when the discharge air temperature is low):
- Indoor discharge air temperature >13ºC.
- The thermostat will switch on depending on the indoor discharge air temperature.
d5 – Heating air temperature drop prevention
This function prevents a drop in the air temperature by decreasing the fan speed, apart from the settings on the remote
control.
d6 – Room temperature control for energy saving
This function is useful when energy must be saved automatically. The outdoor air temperature thermistor detects that the
air conditioning charge is low, in line with the outdoor temperature.
d7 – Only for Econofresh kit
This function is used to set the fresh outdoor air damper minimum opening selection.
E1 – KPI ventilation mode
This function is used to set the unit ventilation mode with energy / heat recovery
This function is useful to set the heat exchanger ventilation mode. The setting condition and ventilation mode are shown
below:

Effective ventilation mode selection (ventilation with total heat exchanger or ventilation bypass) to save energy by
detecting the difference in temperature between indoors and outdoors.
01 Heat is exchanged continuously when the heat exchanger is started.
02 Heat is not continuously exchanged when the heat exchanger is started.
E1 – Econofresh cooling mode
This function allows to the outdoor air damper to be opened.
E2 – KPI Increasing air supply volume
This function is useful when the air supply volume must be increased using the high-speed, one-way valve on the fan
motor during total heat exchanger operations. This increases the pressure in the room with greatest air volume in relation
to adjoining rooms and prevents the entry of contaminated air or unpleasant smells.
E2 – Econofresh enthalpy sensor
This function selects the enthalpy sensor input.
E3 – Not available
E4 – Pre-cooling / pre-heating period
This function is useful to delay start-up of the total heat exchanger.
E5 – Not available
E6 – Indoor fan operation time after cooling operation stoppage
This functions prevents the condensation accumulation in the unit by keeping the fan running after it is switched off.
E7 – Not available
