A zone control panel for use with an HVAC system having zone control and a variable speed blower, and a method for controlling a fluid temperature conditioning device. In one aspect, the zone control panel includes a plurality of thermostat terminals for receiving thermostat signals, a plurality of damper terminals for transmitting damper control signals, and one or more terminals for transmitting signals to control a fluid temperature conditioning device having a variable speed blower. The zone control panel also includes a blower terminal for transmitting a signal to a dehumidification terminal associated with the fluid temperature conditioning device, where the dehumidification terminal is labeled or indicated for use with a dehumidification operating mode or for initiating a dehumidification operating mode of the variable speed blower. The blower terminal changes state in response to the number of zones that are calling for conditioning and changes between only a first off state and a second alternating current (AC) signal state. The change in the state of the blower terminal causes the speed of the variable speed blower to change.
