Fan operation on the Fresh Air Intake type units
When the return air dry temperature is 5°C [41°F] or below, units may be forced to operate in the heating mode to prevent
humidifier from freezing up and to prevent cold drafts.
The fan will stop when all refrigerant systems are in trouble and during the defrost cycle. Refer to the table below for how to
set the related switches and for the operation patterns.
1) The settings in the shaded areas indicate factory settings.
2) Turning on the fan during the defrost cycle will send cold air into the room, delay normal operation from being resumed, and
cause the room temperature to drastically drop. To avoid this, set SW3-4 to OFF.
3) The operating temperature (return air dry temperature) of the fan is 0°C [32°F] or above. If the fan is operated at the outside
temperature below 0°C [32°F], depending on the ambient air conditions, dew condensation may form on the panel surface.
Use caution so that dew drips will not damage the surrounding equipments.
2) SW2,SW3-2,SW3-9,SW3-10,SW4
(3) Address switches
How to set the indoor unit addresses depends on the system. Refer to the Outdoor Unit Installation Manual and other related
documents for how to set the addresses.
Each address consists of two digits.
(Example)
To set the address to "3," set the 1's digit to "3" and leave the 10's digit to "0."
To set the address to "25," set the 1's digit to "5" and the 10's digit to "2."
3. Switch functions <Remote controller>
(1) MA remote controller (PAR-21MAA)
MA remote controller does not have switches. Refer to the Operation Manual for how to make the function settings.
