. System pattern outline
*1: When one of the two remote controllers is switched ON/OFF, the other remote controller switches ON/OFF synchronously.
*2: When one of the three remote controllers is switched ON/OFF, the other remote controllers switch ON/OFF synchronously.
Or when the indoor unit is switched ON/OFF, the system of the Lossnay unit and Dx-coil unit switches ON/OFF synchronously.
*3: Cannot be controlled by M-NET system controller nor MA remote controller of the indoor unit.
*4: Fan speeds can be changed by 0-10VDC input or a volt free contact and can be fixed at the fan speed 3 if necessary.
*5: The ventilation mode is set to the heat recovery mode during the heating and fan modes.
The ventilation mode can be set to the bypass ventilation mode by a volt-free contact if necessary.
*6: When Lossnay is interlocked with City Multi indoor unit, the target temperature information and the operation mode information from Dx-coil have a priority used for
automatic ventilation mapping or Night-purge starting condition etc..

Can be changed from
PZ-61DR-E.
Can be changed from PZ-61DR-E, M-NET
system controller or MA remote controller (for
the indoor unit). The selectable fan speeds
depend on the model of remote controller.

Fan speed
Fixed at fan speed 4
(Fan speed can
be changed by the
external input to
Lossnay and be fixed
at fan speed 3 if
necessary.)
Operating at
selected fan
speed
When Lossnay unit goes to fan
speed 1 or 2 during thermo-ON,
Dx-coil unit becomes thermo-OFF
forcibly.
Ventilation
mode
Fixed at automatic mode
(The ventilation mode is
always the heat recovery
mode during the heating
and fan mode.)
Operating
at selected
ventilation mode
The Dx-coil unit can be switched
thermo-ON in any ventilation
mode depending on temperature
conditions.
OFF
OFF
OFF
When one of the two remote controllers is switched ON,
the other remote controller switches ON synchronously.
Cannot be changed by
PZ-61DR-E.
Heating/Cooling/Fan/Auto
Cannot be changed by
PZ-61DR-E.
Fan speed 1, 2, 3 or 4
Cannot be changed by
PZ-01RC.
Heat recovery/Bypass/Auto
Cannot be changed by
PZ-01RC.
When one of the two remote controllers is switched OFF,
the other remote controller switches OFF synchronously.
For system pattern Z, the functions that can be used depend on the model of remote controllers.
