i. COMFORT OPTIONSÐSUPER DEHUMIDIFY (See Quick Reference Guide)
The Super Dehumidify option is possible when this unit is installed with a field supplied Thermidistat™ control (Super- Dehumidify does not require an outdoor temperature sensor). The following configuration is recommended for maximum cooling/dehumidifying comfort. This configuration will im- prove the comfort provided by the air conditioning system if more humidity removal is desired. While providing this im- proved comfort, the system will operate efficiently, but not at the published ARI SEER efficiency. During cool-to-dehumidify call, it provides maximum dehumidification by reducing airflow to a minimum. The actual super dehumidify command from Thermidistat™ control to the indoor unit is a ªYº signal without a ªGº signal in addition to dehumidify signal. The indoor unit responds to this combination by reducing the airflow to a minimum. All other characteristics of cool to dehumidify are the same.
The following system configuration is recommended for maxi- mum cooling/dehumidifying comfort (See Fig. 8).
(1.) HEAT-Factory selected to match gas heat size of unit installed.
(2.) AC/HP Size-Factory selected to match system size, please verify.
(3.) SYSTEM TYPE-Factory selected on 583B system AC-
AIR CONDITIONER.
(4.) AC/HP CFM ADJUST-Select NOM (Lo for 060).
(5.) ON/OFF DELAY-Select ENH profile.
(6.) CONTINUOUS FAN-Select desired fan speed when ther- mostat is set to continuous fan.
(7.) DEHUMIDIFY MODE-Remove J1 jumper to activate.
NOTE: J1 jumper should only be removed when a Thermidis- tat™, humidistat or capable zoning control is installed.
(8.) LOW VOLTAGE CONNECTIONS-Make connections as shown in ELECTRICAL CONNECTIONS section.
(9.) CONFIGURE THERMIDISTAT™-Follow Thermidis- tat™ (or capable zoning system) installation instructions for Super Dehumidify operation.
ACCESSORY INSTALLATION
a.AUXILIARY TERMINALS
The AUX and HUM terminals on the Easy Select™ Board are tied directly to the G terminal, and provide a 24-v. signal whenever the G terminal is energized (See Fig. 6). During Super dehumidify mode, the G signal is not present and the auxiliary terminals are not energized. If the installation includes the use of this operating mode, do not use these terminals to control accessories. See Electronic Air Cleaner and Humidifier sections for further information.
b.ELECTRONIC AIR CLEANER CONNECTIONS
The AUX1 and AUX2 terminals are not always energized during blower operations, as described above. When using an electronic air cleaner with the unit, use Airflow Sensor P/N.
Ð4Ð
KEAAC0101AAA. The airflow sensor turns on electronic air cleaner when the blower is operating.
c.HUMIDIFIER/HUMIDISTAT CONNECTIONS
Easy Select™ Board terminals HUM1 and HUM2 are provided for direct connection to the low-voltage control of a humidifier through a standard humidistat (See Fig. 6). These terminals are energized with 24-v. when G thermostat signal is present (See Fig. 6 & 7). Alternately, the 24-v. signal may be sourced from the W and C on the 9 pin connector. When using a Thermidis- tat™ Control, Zone Perfect Plus or Comfort Zone II, the 24-v. signal may be sourced directly from the Thermidistat™ HUM terminal (See Fig. 6, 7 & 8).

d.DEHUMIDIFY CAPABILITY WITH STANDARD HUMIDISTAT CONNECTION
Latent capacities for this unit are better than average systems. If increased latent capacity is an application requirement, the ICM board provides connection terminals for use of a standard humidistat. The unit will detect the humidistat contacts opening on increasing humidity and reduce its airflow to approximately 80 percent of nominal cooling mode airflow. This reduction will increase the system latent capacity until the humidity falls to a level which causes the humidistat to close its contacts. When the contacts close, the airflow will return to 100 percent of selected cooling airflow. To activate this mode, remove jumper J1 and wire in a standard humidistat (See Fig. 7).
e.DEHUMIDIFY AND SUPER DEHUMIDIFY CAPABILITIES
This model unit is capable of responding to a signal from indoor system control (Thermidistat™ or capable zoning control) to operate in comfort control modes such as Super Dehumidify Mode. Consult literature provided with indoor system control to determine if these operating modes are available, and to see control set up instructions. No special setup or wiring of unit is required.
