( 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.
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 (function selection switch) on the Lossnay circuit board. Refer to page 25 and 26. )

Input terminals
a. High (Extra High)/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 fan speed selection, PZ-60DR-E displays "Automatic
Operation
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 controllers can
change the fan speed display; however, the fan will remain fixed at the input fan speed selection
of High ( Extra High ) /Low.
When PZ-60DR-E is used in a system of multiple Lossnay units, input of High ( Extra High ) /Low
Multiple
fan speed into the "Main" Lossnay will permit the switching of the fan speed of all Lossnay units
units
within the same group. When PZ-60DR-E is not used, input High/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 input.
• A remote display adaptor ( PAC-SA88HA-E ) , which is sold separately, is required for the connections.
