Operation Monitor” and “Bypass Operation Monitor” are shared with “Operation Monitor with Delay Function 1” and “Operation Monitor with Delay Function 2” respectively.
When the aforementioned switches (SW2, and SW5) are at the factory setting, type LGH-15 to 100 will all be at the OFF setting, and type LGH-150 and 200 will all be set to OFF except for SW5-10
In systems with multiple Lossnay units, ensure that one unit is set to "Main" and all the others are set to. When locked with an external device, be sure to connect the external device to the Lossnay it is set to. Functions can be switched from the PZ-60DR-E even after the function selector is set on the Lossnay PCB.
Settings of the PZ-60DR-E override the settings of the function selector switch of the Lossnay board.). When two remote controllers are used, “24HR VENTILATION”, “LOSSNAY FUNCTION” and “INTERLOCK SETTING” can only be set on the “Main” remote controller. The "Main" and "Sub" remote controllers are automatically determined by communication when the main unit is turned on.
The page where "24HR VENTILATION", "LOSSNAY FUNCTION" and "INTERLOCK SETTING" are displayed is the "Main" remote control. For information on operating the PZ-60DR-E, refer to the Lossnay remote control PZ-60DR-E installation manual and the operating instructions.
Change
When using two remote controls, the 24-hour ventilation setting is not allowed by the "Sub" remote control. Even during high/low ventilator speed switching input (Refer to pages 33 and 34), 24-hour ventilation (extremely low ventilator speed operation) will be prioritized. When two remote controls are used, the following settings are only allowed for the "Main" remote control.

Switching the ventilation mode will not be possible during night purging (bypass ventilation is fixed).
Hold the A button and simultaneously press the F button for 2 seconds, or L button) (Hold the A button and at the same time. This mode displays the total working hours of Lossnay, checks the Lossnay address and displays the error history .If the remote control is entered into Maintenance Mode during timer operation, the timer operation will be cancelled.
When using two remote controls, if one remote control is set to remote control maintenance mode, Button response can sometimes be slow due to communication processing; this is not an error. Alternately displays at 0.5 second intervals the fault number, generated attribute and address as the most recent fault history stored with the remote control.
This shows the error number and attribute when the address is not set (i.e. address 00).

Troubleshooting
Is the address setting on the Lossnay circuit board (SA1, SA2) set to the correct number. When using only one Lossnay, the Main/Sub switch (SW1) on the Lossnay circuit board is set to "Sub". Check the external signal type and setting of the pulse input switch (SW2-2) on the Lossnay circuit board.
Check the setting of the lock mode setting switch (SW5-7, SW5-8) on the Lossnay circuit. Check the setting of the address setting switches (SA1, SA2) on the Lossnay circuit. The length of the transmission cable installation is longer than specified (longer than a maximum of 200 m from the power supply unit, longer than 500 m between the ends).
The length of the transmission cable wiring is longer than specified (longer than maximum 200 m from the power supply unit, longer than 500 m between ends). The length of the transmission cable wiring is longer than specified (longer than maximum extension 200 m, longer than 500 m between ends). When using PZ-60DR-E, “POWER VENT START” is set to “on” with the function selection of the remote control.
When using the PZ-60DR-E, “RECOVERY SETTING” is set to “on” or “AUTo” with the function selection of the remote controller. When the PZ-60DR-E is not used, the function selector switch (SW2-6 or SW5-4) on the Lossnay PCB is set to ON. When using PZ-60DR-E, “RECOVERY SETTING” is set to “oFF” with the function selection of the remote controller.
The length of the transmission cables is longer than specified (longer than the maximum extension of 200 m, longer than 500 m between ends). When not using the PZ-60DR-E, the function selection switches (SW2-6 or SW5-4) on the Lossnay circuit board are set to ON. Check the operation monitor output setting with the PZ-60DR-E function selector or the function selector switch (SW5-2) on the Lossnay circuit board.
Disassembly and assembly
4 Slide the connector covers (with the connector) towards the side of the Lossnay core and then remove it from the unit. Remove the side engine EA in the same way.
