Continuous Fan

When the thermostat is set for "Continuous Fan" operation and there is no demand for heating or cooling, the blower control will provide 50% of the COOL CFM selected.

HUM terminal which provides for connection of a humidis- tat. The JW1 jumper on the blower control board must be cut to activate the HUM terminal. The humidistat must be wired to open on humidity rise. When the dehumidification circuit is used, the variable speed motor will reduce the se- lected air flow rate by 18% when humidity levels are high.

An LED (D1) lights when the blower is operating in the de- humidification mode.
