Restrictions - Mitsubishi Electric Mr. SLIM PEAD-RP60JA Technical Manual

4. Restrictions

Damper system controller setting will be prioritized. Set function on a damper system controller.
Also, settings and error codes set by a remote controller will not be reflected to the damper system controller.
Signal priority: Damper System remote controller > (analog input) > ME or MA remote controller
* Analog input: only air volume control will be effected

*1 Check operation. No restrictions in functions when 0-10V analog input is connected on its own.
*2 Refer to the below diagram of operation temperature range when bypass damper is not available and when there is no damper delay
operation.
Operation temperature range:
To protect unit, there are restrictions when bypass damper is not available and when there is no damper delay
operation for 1 minute. The restriction will depend on piping length and air inlet temperature.

Restrictions
If there are cooling/heating simultaneous
operation set from damper system
controller in a system of Y series outdoor
unit + multiple indoor unit, damper system
remote controller will display operation
mode but indoor fan may stop.
Operation mode cannot be controlled with
M-NET system controller.
Do not combine level input of indoor unit
ON/OFF and IT transmission.
Transmission error cannot be detected
when the IT transmission line is cutoff or
the connector is not plugged in.
Indoor unit error code will not be displayed
on damper system remote controller.
ON/OFF control from damper system
remote controller is not available when
ON/OFF operation is prohibited from
system remote controller.
Damper system setting is not available for
models PEAD-RP35, 50JA(L), PEFY-P20,
25, 32, 40, 50VMA(L)-E.
Use bypass damper to prevent rapid
change in external static pressure. If
bypass damper is not available, set a
delay timer circuit which starts the damper
in 1 minute after receiving damper system
input to indoor unit.

Suction air temperature (°C)
Indoor unit fan will stop when a different mode from outdoor unit
operation mode is selected.
If an operation mode is prohibited, operation mode will be
displayed, but indoor unit will operate in FAN mode.
Level input is prioritized and damper system controller input will
be invalid.
After the IT transmission line cut is fixed or the connector is
plugged in, CN105 will automatically recover. If indoor units
cannot be controlled from damper system remote controller,
check the IT transmission line or the connector.
Indoor unit error will be notified by CN105 transmission. To
check error code when in service, setting of MA or ME remote
controller is recommended.
Because operation prohibition will be prioritized, setting at
damper system controller will be invalid. Do not combine ON/
OFF prohibition and IT transmission.
For these models, air volume will not change with damper
system setting.
In heating, to protect the unit, unit may stop due to high pressure
error. When bypass damper is not used, as shown in the
below figure, operation range will be limited depending on inlet
temperature.
