Interlocked Lossnay
This is a Lossnay linked to City Multi, or Mr. Slim indoor units. This is a Lossnay that has been set to interlocked group set-
ting to receive signals and operate via indoor unit's remote controller → indoor unit → Lossnay.
Non-interlocked Lossnay
This is a Lossnay that is not set to interlocked group setting with City Multi nor Mr. Slim indoor units. It operates using direct
operating signals from the Lossnay remote controller and/or centralised controller.
Ventilation Mode
This mode controls the Lossnay damper and permits selection of heat recovery ( Heat ex. ) , by-pass or auto modes.
Delayed Operation
The Lossnay that has been set to interlocked group setting with the indoor unit will have its operation delayed for 30 minutes
after the operation of the indoor unit. When using PZ-41SLB-E, the time setting that can be set for delayed operation are 10,
20, 30, 40, 50 and 60 minutes.
External Control Input
This is an input signal for operating the Lossnay that has been sent from an external device. It is compatible with 12V-24V
DC or uncharged a-contact signal.
Operation Mode
This mode is used for selecting enabling/disabling of the on/off control signal from an external device and for setting inter-
locked operation of the external device and the Lossnay.
Please Refer to page 128 for details.
