( 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
function 1" and "Operation monitor with delay function 2", respectively.
( Switch with the DIP switch on the Lossnay circuit board. Refer to page 30 and 31. )

outdoor air temperature is
59°F (15°C) or higher.
*1 Terminal 7 of TM3 is a common terminal with bypass operation monitor/operation monitor with delay func-
tion 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.

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 control-
lers 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 PZ-60DR-E is used in a system of multiple Lossnay units, input of High ( Extra High ) /Low/
Multiple
Extra Low fan speed into the "Main" Lossnay will permit the switching of the fan speed of all
units
Lossnay units within the same group. When PZ-60DR-E is not used, 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 input of the Extra Low fan speed is not available for the LGH-F1200 type.
