Description Of The Optional Remote Control Functions - Hitachi RCI-1.0FSN3 Service Manual

6 Optional functions
In case that the set temperature is changed and kept within the set time at "F4", the temperature is automatically changed
(4)
to "F5" and "F6". In case that the set temperature is out of range at "F5" and "F6", it is applied within upper and lower limit
for the set temperature.
Operation is stopped by pressing the run/stop switch for 3 seconds.
(5)
When the unit is restared by the remote control switch, the temperature automatically changes to the setting temperature
(6)
of "F5" or "F6".
N O T E
• Makes the changes to the optional settings at least three minutes following start-up.
• On modifying the "CF" (air outlet louver angle change) setting, restore the power supply or allow the automatic
louver to make a full cycle in automatic mode to apply the optional setting.
• The optional function settings are different depending on the indoor or outdoor units. Check that the unit has
the optional setting.
• Save the optional settings made on each outdoor and indoor unit in the "Setting" column of the table.

6.3.3 Description of the optional remote control functions

b1 – Removal of heating temperature compensation
This function is useful when the thermistor is removed from the suction area of the indoor unit and installed somewhere
else. It is used when the temperature setting displayed on the remote control and the inlet air temperature of the indoor
unit must be the same.
b2 – Circulator function at heating Thermo-OFF
This function is useful when the air in the room is stratified (hot air accumulates at the ceiling). Air stratification may occur
if LOW has been selected with the heating thermostat off. This function prevents air stratification in the room after stopping
the air conditioning system.
The circulation pump function maintains the fan speed, whether the thermostat is on or off. Hence, the air movement in the
room is kept at the same level to ensure even air distribution.
N O T E
If the indoor unit has an automatic louver, this function also remains active when the heating thermostat is swit-
ched off.
Everyone has a different perception of coolness, heat and air flow and, therefore, this issue should be discussed
with the client and the unit set according to the results of the conversation.
b3 – Forced compressor operation for at least three minutes
This function is used to protect the compressor preventing it from being started or stopped for periods of less than three
minutes. On enabling this function, the mode enabling operations for a minimum of 3 minutes is added.
N O T E
In the case of SET-FREE units, this function is standard, even when the setting is not available.
The compressor stops immediately when the safety device is activated or ON/OFF is pressed.
To cancel this function, see C7 – Cancellation of the forced compressor operation for at least three minutes.
When this function is cancelled, the mode enabling operations for a minimum of 3 minutes remains available.
