LG MULTI V HYDRO KIT ARNH963K2A4 Installation Manual page 57

Connecting Multiple Hydro Kits to One Remote Controller
(Group Control), continued.
1. Verify power is OFF.
2. Choose which Hydro Kit will be the "Master" unit of the group. Set
DIP Switch No. 1 on DIP Switch Bank No. 2 to OFF.
3. For all the Hydro Kits designated as Slave units, set DIP Switch
No. 1 on DIP Switch Bank No. 2 to ON.
4. Starting with the Hydro Kit Master unit, plug in the male end of
the pigtail cable into the CN-REMO socket.
5. Plug the male end of the extension cable from the previous Hydro
Kit unit into the CN-REMO socket.
6. Plug the Y-cable into the pigtail at each Hydro Kit, except for the
last Slave Hydro Kit in the group (Y-cable is not necessary).
7. Connect two extension cable segments to each Y-cable, except
for the Y-cable connected to the Master Hydro Kit.
8. At the Master Hydro Kit, connect one extension cable and the
communications cable from the controller to the Y-cable.
• A wireless remote controller can be used at the same time as
Group Controller.
• A Dry Contact and a Central Controller also can be connected at
the same time, but only the address of the Master Hydro Kit can
be recognized (Slave Hydro Kits cannot be individually controlled
by the Dry Contact or Central Controller; these will follow Master
Hydro Kit operation).
• Some remote controllers cannot operate with a Dry Contact and
Central Controller; contact an LG representative for more informa-
tion.
• When multiple Hydro Kits are connected to one controller, it is nec-
essary to only connect the temperature sensor to the Master Hydro
Kit and not the Slave Hydro Kit(s).
