Remote controller installation
NOTE
• The remote controller wire should not be bundled
with other wires (mains, etc.), or installed with other
wires in the same conduit, as malfunction may
result.
• Install the remote controller away from sources of
electrical interference and electromagnetic fields.
• If electrical interference is unavoidable,
countermeasures such as appropriate filtering
should be employed.
1. For removal of the remote controller’s lower
case (rear case), insert the tip of a straight blade
screwdriver, or the like, into the two openings at
the bottom of the remote controller to open the
lower case.
2. Fix the remote controller’s rear case by wood
screws (2 pcs.). Do not over tighten, as it may
damage the rear case.
3. Connect the wires from the Hydro unit to the
remote controller terminal block.
(Refer to “How to wire the remote controller”.)
Connect the wires of the remote controller
following the terminal numbering convention of
the Hydro unit to prevent miss wiring. (Do not
apply AC 208-230V mains voltage to the remote
controller as it will be damaged).

Installation
For a dual remote controller system, install the remote
controllers in the following way.
1. Set one of remote controllers as the header
remote controller. (Remote control of hydro unit
is preset as Header (DIP SW1 = OFF).)
2. Set the DIP switch on all other remote controller
P.C. boards to Second. (Optional remote control
is preset as Second (DIP SW1 = ON).)
• Set DIP SW2 to ON (Room temperature) on the
remote control which you will control the room
temperature with.
DIP SW2 of optional remote control is preset to ON
(Room temperature).
Either one of header or second remote control must
be set as room temperature control.
