• Common items
- In case of changing from Thermo-ON to Thermo-OFF at the beginning of the automatic mode, the fan speed
during Thermo-OFF is that of right after Thermo-OFF. Also, the switching of fan speed is not performed during
Thermo-OFF. (When switching from Thermo-ON to Thermo-OFF, the maintenance of fan speed for 3 minutes is
released, and the switching of fan speed depending on temperature di󰀨erential is carried out)
- The target of the automatic switching is the part of the control which operates at the normal setting fan speed.
- When using a room thermostat and in test run, it is set to setting fan speed.
- Even in case that the heating circulator is enabled (Function selection b2=01), it is set to the fan speed of the
automatic indoor fan speed mode.
? NOTE
• The maximum fan speed in “Auto” mode is “High”, unless EF function is also activated.
• Econofresh present, E1=01 and Fan speed setting is “Auto” mode, fan speed is xed to “High”
EF – Automatic indoor fan speed mode (supporting High H)
This function allows to increase the maximum fan speed to “High H” in “Auto” mode.
• Cooling
Indoor control temperature (Ti2) - Setting temperature 2 (Ts2) ≥ 2ºC: Setting fan speed
Indoor control temperature (Ti2) - Setting temperature 2 (Ts2) ≥ 1ºC: Medium
Indoor control temperature (Ti2) - Setting temperature 2 (Ts2) < 1ºC: Low
• Heating
Setting temperature 2 (Ts2) - Indoor control temperature (Ti2) ≥ 2ºC: Setting fan speed
Setting temperature 2 (Ts2) - Indoor control temperature (Ti2) ≥ 1ºC: Medium
Setting temperature 2 (Ts2) - Indoor control temperature (Ti2) < 1ºC: Low

F1 – Automatic OFF timer setting
This function is used to switch o󰀨 the timer automatically when the unit is started using the remote control.
It is not possible to cancel or change the timer o󰀨 setting during automatic timer o󰀨 setting. However, it can be cancelled
when the unit is stopped. When the unit is restarted, the o󰀨 timer setting period is established according to the optional
setting. Do not set the functions “0C”-”0F” when two remote control switches are used in the same remote control group.
? NOTE
This function is not available for control using CSNET Manager 2 or 7-day timer.
F2 – Remote control main-sub setting
This function is useful when conguring two remote controls for the same installation: one in main mode and the other in
secondary mode.
