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.
An extra RJ25 cable is supplied to allow direct connection of the RIU at the PoolPak™ control panel during service or
startup.
OUTSIDE AIR TEMPERATURE AND RELATIVE HUMIDITY SENSOR (2)
The ECC III uses an outside air temperature and humidity sensor to make smart economizer decisions and to prevent air-
cooled condenser operation during low ambient conditions.
The sensor should be mounted on the exterior surface of a north-facing surface without exposure to direct sunlight. Wire
entry to the sensor terminal box is provided with a compression-type fitting, suitable for cable diameters of from 1/8 to
1/4 inch.
Do not connect a conduit directly to the sensor’s terminal box
. Use a small piece of UV-resistant cable to make the
transition from the conduit to the sensor. A direct conduit connection will allow condensation to form inside the sensor,
resulting in permanent damage.
Orient the sensor as shown on the included instruction sheet. Proper orientation of the sensor and radiation shields is
essential. Carefully review the wiring connections shown on the field-wiring diagram.
Improper connection may
damage the sensor and/or the ECC III control module
. The cable should be four-conductor (two twisted pairs), 16–20
AWG copper.
!
CAUTION
Improper connection may damage the sensor and/or the ECC III control module.
The cable should be four-conductor (two twisted pairs), 16-20 AWG copper.
COLD SURFACE TEMPERATURE SENSOR (3)
This sensor measures the temperature of the coldest surface in the pool enclosure. When the temperature of the surface
drops within 5°F of the space dew point, the dew point set point will automatically be reset downward to help prevent
condensation on the cold surface. It should be noted that this function will not be able to compensate for lower-quality
building materials, such as single-pane glass or non-thermally broken window frames.
The sensor should be mounted so it is in direct contact with an exterior door, window, or skylight frame not subject to
direct sunlight. Do not mount on a gang box. In cases where there are no exterior doors or windows, the sensor should be
mounted on the interior surface of an exterior wall. Avoid mounting the surface temperature sensor where it will get direct
exposure from sunlight. The sensor housing has a single 1/8-inch hole for mounting.
Wire as shown on the field-wiring diagram. Electrical connection should be made with two-conductor (one shielded,
twisted pair), 16-20 AWG copper cable. Connect the shield drain wire to ground at the PoolPak™ control panel end only.
