Manufacturer: Carel

INTRODUCTION

The Remote Interface Unit (RIU) is the main user interface for the ECC control systems. It can be installed at the PoolPak
unit or in another convenient location up to 1000 feet away. Each PoolPak supports connection to as many as three
RIUs. All status, set points and configuration points are available through the RIU.

MOUNTING

The RIU should be mounted in a convenient location, outside the natatorium, that is protected from splashing pool
water and corrosive air. The ambient temperature of the mounting location must always be greater than 32°F. The
maximum distance from the PoolPak control panel is 1,000 feet. For distances greater than 1,000 feet, contact the
factory.
!
WARNING
Failures due to mounting the keypad inside the pool room will not be covered under warranty.
The RIU includes a mounting bracket that is designed to fit a standard, single-gang box, mounted horizontally in the
wall. Do not use the "through-the-wall" mounting option. The RJ25 jack and most of the black cable should be placed
inside the box before installing the mounting bracket. Use the screws that come with the box to secure the bracket.
Using an "extra deep" box will make it easier to fit the RJ25 cable and jack inside. After the mounting bracket is
secured to the wall, connect the RJ25 cable to the jack on the back of the RIU. Slide the RIU onto the bracket until it
snaps into place.

WIRING

Proper polarity and connection is essential for correct operation of the RIU. Improper wiring can cause permanent
damage. See below for the correct cable to connect the RIU (plug in back) with each model controller. At minimum,
cable must be 6-conductor (three twisted pairs), 16-20 AWG.
For hard-wiring the RIU to the controller, refer to the field wiring diagram in the Installation and Operation Manual
specific to your unit.
