4.7A Humidity/Fan Control Panel WITHOUT Fresh Air Ventilation or Damper
The humidity/fan control panel automatically controls the humidity of the living space. The humidity/fan control panel contains an adjustable humidity control and a fan switch. The panel has a cover that must remain open to the air within the living space for accurate
humidity sensing. Position the fan switch ON when the home is occupied. This filters and circulates air throughout the home. For humidity control operation refer to section 4.8.
4.7B Humidity/Fan Control Panel
WITH Fresh Air Ventilation and WITHOUT Damper
The humidity/fan control panel automatically controls the humidity of the living space. The humidity/fan control panel contains an adjustable humidity control and a fan switch. The panel has a cover that must remain open to the air within the living space for accurate humidity sensing. Position the fan switch “ON” when the home
is occupied. This filters and circulates air throughout the home. Outside air is introduced whenever fan is “ON.” Manual operation of fan filter switch controls outside air and ventilation. Since the fan operates whenever the
4.7C Humidity/Fan Control Panel
WITH Fresh Air Ventilation AND Damper
In this configuration, a motorized damper has been installed in the fresh air duct. When the fan/filter switch is in the “OFF” position, the damper is closed. The

4.7E DEH 2000 Digital Controller
WITH Fresh Air AND Damper
Refer to Section 5.
4.7F DEH 2000 Digital Controller WITHOUT Fresh Air
Refer to Sections 5 through Section 5.2G only.
4.8 Humidity Control Adjustment
Set the humidity control to the desired humidity level for the home. Turning the knob clockwise results in a drier setting. See the back of the control panel cover for set points. The dehumidifier will run continuously until the relative humidity (RH) is reduced to the humidity control dial setting. Setting the humidity control to lower RH levels will NOT increase the unit's dehumidification rate; the
unit will simply run longer to reduce the area's RH to the setting. The
4.9 Fan/Filter Switch
Turning ON the fan/filter switch to FAN ON” position will cause the
throughout the house. When the switch is “FAN AUTO” position the impeller fan will operate only when the humidity control calls for dehumidification or when the ventilation timer calls for ventilation.
4.10 Ventilation Timer
The ventilation timer controls the impeller fan and the motorized fresh air damper. When the ventilation timer is activated, the UA- 135H will circulate the indoor air, and bring in fresh air from outside. The ventilation timer should be set for the required ventilation of the residence. The home should be ventilated with fresh air as suggested by applicable codes and standards.The ventilation timer is an electronic timer that displays the current time. This timer has battery backup, so it will not require resetting after a power outage. Following a prolonged power outage the display of the timer will flash on and off indicating a power outage has occurred. The one- minute time increments of the ventilation timer allow you to program the ventilation of your home to fit your schedule.
The ventilation timer allows six programs with each program having one "on" and one "off" event. A program allows the user to turn the ventilation on at a certain day and time, then it allows them to turn the ventilation off at a certain day and time. Each of these programs can be repeated daily or weekly or during a specified block of days. All six of the programs operate independently of each other. If the timer fails to operate or operates erratically, check that the control
