(2) Start-up process
When the power is turned on, operation will not be performed for up to 45 seconds to allow Lossnay to perform information settings required for control purposes.
The start-up process can be confirmed by the blinking of LED1 in the Lossnay circuit board (1 second on/1 second off) or the remote controller LED when using the remote controller.

The control indicated below can be performed according to the system that is paired.
●Up to two of the Lossnay remote controllers PZ-60DR-E, PZ-41SLB-E, and PZ-52SF-E can be used in the same group, but they cannot be used together with a different remote controller. When using two remote controllers, be sure to use the same model of remote controller.
Caution ●PZ-41SLB-E cannot be used in M-NET control. When controlling Lossnay in M-NET control, use PZ-60DR-E or PZ-52SF-E.
●When using PZ-60DR-E and mixing the LGH-15 to 100 types together with the LGH-150 and 200 types in a group,set the LGH-15 to 100 types as “Main”.

3Restrictions when switching fan speed
The following restrictions exist when the fan speed is switched.
●When switching between High (Extra High) and Low fan speed, the fan will be stopped for approximately 5 seconds.
●When switching between settings other than Extra Low fan speed and Extra Low fan speed, the fan will be
stopped for approximately 10 seconds.
4Air supply fan forced stop
Under the following conditions, Lossnay will force stop of the air supply fan. However, when the following conditions are met while operating at Extra Low fan speed, the air supply fan will stop, and the exhaust fan will operate at Low fan speed.
(When operating at Extra Low fan speed, the air supply fan and the exhaust fan cannot be stopped separately.)
●When Mr. Slim is in defrost or stopped due to a fault, in an interlocked system with Mr. Slim that has a duct connection with Lossnay.
(For cold inrush prevention, or falling dust prevention)
●When the indoor unit is in defrost, in an interlocked system with a City Multi indoor unit that has a duct connection with Lossnay.
(For cold inrush prevention)
●When the outside temperature is -10ºC or lower, the air supply fan is stopped periodically for approximately 10 minutes to 55 minutes.
(To prevent freezing of the Lossnay core)
(4)Ventilation mode control
Lossnay (heat exchange) ventilation or bypass (normal) ventilation is achieved by switching the air duct inside the Lossnay unit with a damper.
1Ventilation mode
There are 3 control modes.
● Lossnay ventilation (heat exchange ventilation) mode: Heat exchange ventilation is performed regularly via
|
the Lossnay core. |
● Bypass ventilation (normal ventilation) mode |
: Ventilation is performed regularly without going |
|
through the Lossnay core. |
● Automatic ventilation mode |
: A temperature sensor built into the unit provides |
|
automatic ventilation to a suitable ventilation mode. |
|
In addition, energy saving ventilation is provided by |
|
interlocking with a Mr. Slim or City Multi indoor unit. |
— 27—
2Damper control for each system
The control indicated below can be performed according to the system that is paired
●Up to two of the Lossnay remote controllers PZ-60DR-E, PZ-41SLB-E, and PZ-52SF-E can be used in the same group, but they cannot be used together with a different remote con-
troller. When using two remote controllers, be sure to use the same model of remote con- Caution troller.
●PZ-41SLB-E cannot be used in M-NET control. When controlling Lossnay in M-NET control, use PZ-60DR-E or PZ-52SF-E.

3Bypass ventilation prohibited
When the conditions described below are applicable, the ventilation mode will be fixed at Lossnay ventilation. When bypass ventilation has been set from the remote controller or the system controller, damper operation will be set to Lossnay ventilation, even though bypass ventilation is displayed on the ventilation mode display.
●When the outdoor temperature is 8ºC or lower. (Product condensation prevention)
When bypass ventilation prohibition has been set under this condition, the prohibition will be cancelled when the outdoor temperature goes from a temperature of less than 10 ºC to one higher than 10ºC.
●When there is an outdoor temperature (Outdoor Air) thermistor fault.
●When, in the automatic ventilation mode, there is an outdoor temperature (Outdoor Air) or indoor temperature (Return Air) thermistor fault.
●When Lossnay is set to the automatic ventilation mode and interlocked with Mr.Slim or City Multi indoor units
set to the fan operation mode.
4Damper operation
The damper provides control with a 30 second period. Accordingly, a delay of 30 seconds maximum may be generated from ventilation mode switching to damper operation.
5Automatic ventilation algorithm temperature map
Ventilation mode switching of Lossnay ventilation/Bypass ventilation in the automatic ventilation mode is in accordance with the following map.
a.Systems interlocked with Mr. Slim and City Multi indoor units
The map will differ depending on the operation mode that has been set with the A-control remote controller or the K-control remote controller for Mr. Slim, or the MA remote controller or the ME remote controller for City Multi indoor units. There will be switching to the ventilation mode in conjunction with the set temperature of the air conditioner remote controller. Note that the “b” map will be followed while Mr. Slim and City Multi indoor units are stopped.
