(6) External input/output terminals on the Lossnay circuit board
Located on the Lossnay circuit board are terminals for the external output of the Lossnay operating condition,
and input terminals for external switching of the Lossnay fan speed and ventilation mode.
1 Output terminals
The function and contact rating of each output terminal are described below.
"Operation monitor" and "Bypass operation monitor" are in common with "Operation monitor with delay func-
tion 1" and "Operation monitor with delay function 2", respectively.
(Switch with the DIP switch on the Lossnay circuit board. Refer to page 38 and 39.)
Output
Malfunction moni- Turned ON (closed) at time
tor of Lossnay malfunction.
Operation monitor Turned ON (closed) at time
*3 of Lossnay operation.
This can also be turned ON
(closed) at time of air sup-
ply fan operation.
Operation monitor Turned ON (closed) 10 sec-
with delay func- onds after start of air supply
tion 1 fan.
Bypass operation Turned ON (closed) at time
monitor of bypass ventilation.
Operation Turned ON (closed) 10 sec-
monitor with delay onds after start of air supply
function 2 fan when outdoor air tem-
perature is -5ºC or lower.
Turned OFF (open) when
outdoor air temperature is
15ºC or higher.
*1 Terminal 7 of TM3 is a common terminal with bypass operation monitor/operation monitor with delay function
2 output 7.
*2 Terminal 7 of TM3 is a common terminal with malfunction monitor output 7.
*3 The operation monitor can also be used as an air supply fan operation monitor with the setting described
below.

2 Input terminals
a. High/Low/Extra Low fan speed switching input
This is used for external switching of the fan speed by means of a commercially available CO
During the input of High (Extra High)/Low/Extra Low fan speed selection, PZ-60DR-E displays
Operation
"Automatic Fan Speed" indicator. The set fan speed cannot be changed while "Automatic Fan
Speed" is displayed due to operation restrictions. Other remote controllers and system con-
trollers can change the fan speed display; however, the fan will remain fixed at the input fan
speed selection of High (Extra High)/Low/Extra Low.
When using PZ-60DR-E in a system of multiple Lossnay units, input of High (Extra

speed of all Lossnay units within the same group. When not using PZ-60DR-E, input
High/Low/Extra Low fan speed into each Lossnay unit. In this case, the setting is applied only to
the Lossnay units that have received the High/Low/Extra Low input.
• A remote display adaptor (PAC-SA88HA-E), which is sold separately, is required for the connections.
• The LGH-150 and 200 types cannot use the Extra Low fan speed selection input.
