requirements
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 controller of Hydro
Unit is preset as Header.)
2. Set from “Header / Second” in “Initial setting” on
the setting screen.
• To control room temperature instead of water
temperature with this remote controller, set DN “40”
of Hydro Unit to “1”.

To connect the Central Controller and BMS (TU2C-LINK)
CN902 for the central remote control wiring on the Hydro Unit PCB
Communication wiring and central control wiring use 2-core non-polarity wires.
Use 2-core shield wires to prevent noise trouble.
In this case, for the system grounding, close (connect) the end of shield wires, and isolate the end of terminal.
When connecting and controlling the system controller, the central control address (DN03) setting is required.
On some system controllers, DN03 may be set automatically.
For details, refer to the manual of the system controller used and the installation manual.

Requirements for the installation of a
second remote control
Installation
Install the remote controls in a dual
remote control system as follows.
1. Set one of the remote controls as the distributor
remote control. (The remote control of the
hydro unit is preset as the header unit.)
2. Set this under "Main / auxiliary" in "Initial settings" on
the settings screen.
• To control the room temperature instead of the
water temperature with this remote control, set
DN "40" of the hydro unit to "1".
