Dry Mode

Characteristics Of Dry Mode

The Dry Mode dehumidies the space at reduced cooling

capacity to prevent the room temperature from dropping to

uncomfortable levels. In Dry Mode, the system maintains

automatic temperature and fan speed control. The fan only

operates at low, regardless of whether the controller is set for

low or high fan speed.

On entering dry mode, the control system takes note of the

current Room Temperature (Tro).

■ If Tro > 76.1°F (24.5°C), the controller cycles on and off

in cooling mode to keep the room temperature between

Tro and (Tro-2.7°F).

■ If Tro ≤ 76.1°F, the controller cycles on and off in cool-

ing mode to keep the room temperature between Tro and

(Tro-1.8°F).

As shown in Figure 10, while in Dry Mode Operation, the fan

operates at low (L) ow rate, stops for a period of six minutes

while the thermostat is OFF, and then returns to operation at

(L) ow rate. (This control is used to prevent a rise in indoor

temperature while in thermostat OFF mode.)

Step 1.

Press Mode button several times until the Dry mode is selected.

Return Setting

Note: In Dry mode, the system maintains automatic tempera-

ture and fan speed control. Therefore, temperature

setpoint or fan speed settings are not available while

the WSHP unit is in the Dry mode.

Note: To prevent water damage or system failure, do not im-

mediately remove power from the WSHP unit following
