For control by 2 remote controllers (Controlling 1 group by 2 remote controllers)
When using 2 remote controllers, one must be set to "MAIN" and the other must be set to
"secondary".
<MAIN/SUB change over method>
Refer to the installation manual of the remote controller. (Factory default setting is "MAIN".)

If control is performed with a central device (such as central controller), a
group number needs to be set with the remote controller.
See the manual of each central device for details.
Even when the central device is used for controls, you still use the remote
controller to change field settings. Install the remote controller in an
operable location.
For remote operations
Remote operation can be performed by connecting the external input
(Input A) to terminals J1, J2, and JC of the terminal block (X2M).

Supply air volume can be set at a higher level than the exhaust air (Supply
Fresh-Up) or the other way round (Exhaust Fresh-Up) by input from an external
contact point.
Set the fresh-up mode to "Supply" fresh-up or "Exhaust" fresh-up on the remote
controller.

In case of operation combined with an external damper
The printed circuit board of the Heat Reclaim Ventilator main unit opens and closes
the no-voltage contact used for driving the damper in conjunction with the operation
of Heat Reclaim Ventilator .

Wiring instructions
The fan operation signal of Heat Reclaim Ventilator is output from terminals X1
and X2 of the terminal block (X3M) on the printed circuit board.
Do not use any code for the electric wire for linking with the
external damper. Example: VCTF (unusable); VV cable (usable)
