SECTION V: OPERATION
The below is a summary of PoolPak™ operation, service, and maintenance features of the PoolPak™ SWHP unit and
controller. For complete detail, refer to the PoolPak™ SWHP Installation and Operation Manual that can be found on the
PoolPak™ website.
REMOTE INTERFACE UNIT (RIU)
The PoolPak™ ECC III control system includes a Remote Interface Unit (RIU) display/keypad panel that can be located
remotely from the unit for the convenience of the owner. A standard three-line telephone jack connects to the control
system at terminal block T17 using a six-wire cable. The RIU connects to this telephone jack using the special RJ-25
cable supplied.
Normally, the Remote Interface Unit (RIU) will automatically rotate between four different screens to display the status
of the system. Pressing the HOLD/ROTATE key will stop the automatic screen rotation and will hold the presently-
displayed screen. After a 10-minute delay, the screens will resume normal rotation. The user may also turn off the hold
function before the delay terminates by pressing the HOLD/ROTATE key a second time.
Four set points, Space Temperature, Space Relative Humidity, Pool Water Temperature 1 and Pool Water Temperature 2,
can be accessed through the RIU. To change a set point, press the corresponding set point key.

SERVICE DISPLAY CONNECTION
For service convenience, there is an auxiliary RJ-25 jack located on the upper left side of ECC III Control Module #1,
port J10. The RIU may be removed from its remote location and connected here using the special RJ-25 cable supplied with
the control system.
Extensive troubleshooting features accessible from the RIU are described in the troubleshooting section.
MULTIPLE UNIT INTERFACING
When there is more than one PoolPak™ unit installed at a single site, the units should be connected together. This is
necessary so that each PoolPak™ unit can be coordinated. It also allows the owner to access PoolPak™ operational
information for all the units from a single location.
