CFM SELECTION BOARD SETTINGS

For proper system operation the CFM Selection Board jumpers must be set properly.

If a dehumidification control is installed, it is recommended that a mini- mum air flow of 325 cfm/ton be supplied at all times.

Refer to the Tech Guide for the recommended air flow settings for each size condensing unit and matchup.

Set the cooling speed per the instructions for the air handler or furnace by selecting the correct COOL and ADJ taps. Verify the airflow using the LED display on the CFM selection board.

The HUMIDISTAT jumper must also be removed if a dehumidistat is installed.

If installed as a communicating system (outdoor, indoor and thermo- stat), the system will automatically adjust to the optimal airflow settings. These parameters can also be modified using the Touch Screen Com-

DEHUMIDIFICATION CONTROL

A dehumidification control accessory 2HU06700124 may be used with variable speed air handlers or furnaces in high humidity areas. This control works with the variable speed indoor unit to provide cooling at a reduced air flow, lowering evaporator temperature and increasing latent capacity. The humidistat in this control opens the humidistat contacts on humidity rise. To install, refer to instructions packaged with the acces- sory and Figures 7-9. Prior to the installation of the dehumidification control, the jumper across the HUMIDISTAT terminals on the indoor variable speed air handler or furnace CFM selection board must be removed.

During cooling, if the relative humidity in the space is higher than the desired set point of the dehumidification control, the variable speed blower motor will operate at lower speed until the dehumidification con- trol is satisfied. A 40-60% relative humidity level is recommended to achieve optimum comfort.
