DESCRIPTION
It is the function to automatically change the fan speed according to the difference between
the indoor temperature and the desired temperature.
Trough the CN_EXT port in the IDU's PCBA, We can control it as Digital input without Dry
contact module. This function determines the usage of the contact port (CN_EXT) mounted
on the indoor unit PCB.
- Not use : Use CN_CC installer setting(code 42) setting.
- Simple On/Off
- Simple Dry contact : Operation on/off and Hard lock can be used. When the contact is
open, operation off + HL
- Single Emergency stop : When detecting the emergency(open) status, a detected indoor
unit will be operation off + HL
- Occupied/Unoccupied : For 2set point combination, indoor unit determine the occupied
sensor and send the signal to remote controller and central con-
troller.
- All emergency stop : When one of the indoor unit detected the emergency(open) status,
all the indoor unit will be operation off + HL until that unit is released.
- Window contact
- Window contact lock
It is the function to set whether to use the standby mode or priority cooling function of the
outdoor unit and to set the cooling off thermal time when the priority cooling is set.
- Standby mode : When using Multi V H/P product, if you select the operation mode oppo-
site to the outdoor unit cycle, the indoor unit will be on standby to pre-
vent the opposite mode operation. During standby mode, indoor unit
operates as Fan off + Th off until its cycle matches with the outdoor unit
cycle.
- Priority cooling : In MultiV H/P product, when there is a customer (indoor unit) who
wants a cooling mode during the heating cycle, can change the cycle
by giving priority to cooling. In other indoor units, heating is maintained
using a heater. The priority cooling function is available when the emer-
gency heater is set to use (18:01).
- Maintenance time : Once outdoor unit change over to cooling by cooling priority, it
returns to heating cycle after set time.
It is a function to set the outdoor unit cycle and the heater switching operation criterion
according to the outdoor temperature condition.
This function is available when the Aux heater is set to use (25:01).
If the user set outdoor temperature T1 and △T, Indoor unit will select heating stage from
ODU operation, heater operation or OUD+heater
- T1 setting range : -23 ~ 16℃
- △T setting range : 0 ~ 35℃
① (T1 +△T < Outdoor temperature) : Use only ODU
② (T1 < Outdoor temperature < T1 + △T) : Use both heater and ODU
③ (Outdoor temperature < T1) : Use only heater
If the user set outdoor temperature T1 and T2, Indoor unit will select heating stage from
ODU operation, heater operation or OUD+heater
- T1 setting range : -23 ~ 16℃
- T2 setting range : -23 ~ 51℃
① (T2 < Outdoor temperature) : Use only ODU
② (T1 < Outdoor temperature < T2 ) : Use both heater and ODU
③ (Outdoor temperature < T1) : Use only heater
It is the function to set the low noise mode control main agent. (It is the function to set that
only one of the outdoor unit / remote controller can control the low noise operation.)
ODU : It is controlled in the outdoor unit itself according to the outdoor unit
PCB's Dip switch Setting.
- "Function setting – Low noise operation time" function will be deactivated.
RMC : Ignore the outdoor unit PCB's DIP Switch Setting.
- "Function setting – Low noise operation time" function will be activated.
* If you set Master indoor unit setting for ODU function control, you can use this function
It is the function to set the position of humidity detection.
The humidity value of the set position is displayed on the screen.
When setting the CN-PTC (hot water coil), the indoor unit operates by fan mode and heat-
ing operation is performed using only the hot water coil.
Normal : Not use the hot water coil
Special : Use the hot water coil. Auxiliary heating interlock activated
It is the function to apply the offset to the temperature value detected from the remote control.
- Set range : -5℃ ~ +5℃ (by 0.5℃)
Wired remote controller
