4. Installation method (continued)
• Install the duct heater separated from the product by a
distance of 2.2 yd (2 m) or more.
Failure to do so may result in equipment damage due to the
transmission of residual heat from the heater.
• Ensure that the duct heater and Lossnay are wired and that
the Lossnay function settings have been configured, and then
always check operation by trial operation.
• For the duct heater output, see function setting
No. 61
.
When using After-heater output signal, the wiring should be as shown
by the following picture.

When switching fan speed externally
(when a sensor or other equipment is connected)
Using a field supply sensor, etc., make connection by inserting the
optional remote controller adapter (PAC-SA88HA-E or PAC-725AD)
in the connector CN17 (Red) as shown by the figure.
Lossnay will operate at the fan speed following the table below,
regardless of the remote controller setting.

Not used. Insulate completely.
Max wiring length 11 yd (10 m)
Use this in such a way that it ventilates at low fan speed normally,
and when the external sensor detects contamination of indoor air, or
SW1 is on, it changes to high fan speed operation.
When multiple Lossnay units are controlled by one input, PZ-62DR-E
is necessary.
The signal has to be inputted into main unit referring to 3.
Cannot be used in conjunction with the following functions:
- To change fan speed by 0 - 10 VDC input.
- Connecting CO sensor PZ-70CSB-E or PZ-70CSW-E.

SW1: By-pass ventilation operation switch
(When closed: For By-pass ventilation operation)
With SW1 is "ON", the ventilation mode of Lossnay is changed to the
By-pass ventilation regardless of the setting on the remote controller.
When multiple Lossnay units are controlled by one input, PZ-62DR-E
is necessary.
The signal has to be inputted into main unit referring to 3.
* When the outdoor air temperature drops lower than 46˚F (8˚C), it
changes to the heat recovery ventilation. (In this case, ventilation
mode icon on the display of the remote controller does not change
from the previous mode, it might be different from the actual unit
operation.)

To change fan speed by 0 - 10 VDC input
Establish the wire connection by inserting the optional remote
controller adapter (PAC-SA88HA-E or PAC-725AD) in the connector
CN26 (White).
Not used. Insulate

To change fan speed by 0 - 10 VDC input, the wiring should be as
shown by the above picture. Refer to function settings
more details.
When multiple Lossnay units are controlled by one input, PZ-62DR-E
is necessary.
The signal has to be inputed into main unit referring to 3.
Cannot be used in conjunction with the following functions:
- Switching fan speed externally (CN17).
- Connecting CO
CAUTION
• Make sure of correct polarity.
• Do not apply voltages higher than 10 VDC.
