4.2Ventilation Timer and Humidity Control Panel

See Figure 2: The ventilation timer and humidity control panel automatically controls both the ventilation and the humidity of the living space. The ventilation timer and humidity control panel contains an adjustable humidity control, a fan switch, and a ventilation timer. This panel will control the humidity and allow

programmed ventilation of the living space. This panel works in conjunction with the optional fresh air damper to provide ventilation.

This panel should be mounted in a central area of the structure where it can accurately sense the humidity of the air in the living space. The panel has small slots that must remain open to the air within the living space for accurate humidity sensing.

4.3 Humidity Control Adjustment

Set the humidity control to the desired humidity level for the home. 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 Ultra-Aire unit (and refrigerant

based dehumidifiers in general) will reduce a warm space's RH to a lower level than that of a cool space. It is therefore pointless to set the humidity control to excessively low levels in cool rooms; doing so will result in long periods of ineffective dehumidifier run time.

Quality humidity meters are available from the factory and are recommended to accurately monitor humidity levels.

4.4 Fan/Filter Switch

Turning ON the fan/filter switch will cause the central conditioning unit's internal fan to run continuously, whether the central conditioning unit is dehumidifying or not. This function is desirable if the central conditioning unit is used for air circulation and filtration. When the switch is ON, air will be constantly filtered through the central conditioning

unit and circulated throughout the house. When the switch is OFF, the fan will operate only when the humidity control calls for

dehumidification or when the ventilation timer calls for ventilation.

4.5 Ventilation Timer

The ventilation timer controls the fan and the motorized fresh air damper. When the ventilation timer is activated, the central conditioning unit 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 whenever it is occupied.

The ventilation timer is an electronic timer that displays the current time. This timer has a battery backup, so it will not require resetting after a power outage. 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 has 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 panel receives 24Vac from the Ultra-Aire . If 24Vac is present at the control panel, reset the timer by pressing the reset button at the bottom center of the timer face. The reset button is the small recessed button with an R beneath it located below the 1…7 and h buttons. Press the reset button in until the display disappears. Release the reset button. The display will reappear as 00:00. Resetting the timer will clear the time and all program settings. After resetting the timer, follow the instructions below to set the correct time and ventilation programs.

The following instructions explain how to set the ventilation timer. First, set the correct time on the timer by sliding the switch in the upper right hand corner of the timer to the clock symbol + and pressing the 1…7 (DAY), h (HOUR), and m (MINUTE) buttons. Remember that this timer operates on a 24-hour (military time) clock.

Next, set the ventilation time schedule. Slide the switch in the upper right hand corner to the program symbol P “ON” will appear to the right of the time and the number “1” will appear in the lower right hand corner of the display. The “1” and “ON” signify the turn on time for the first program. Press the 1…7 button to choose the days of the week for this program. You can choose Mon-Sun Mon-Fri, Sat-Sun, or any single day of the week. The days chosen are shown along the top of the display on the ventilation timer. Next press the h button to set the hour for the start of the ventilation period. Remember that this timer operates on a 24-hour clock. Then press the m button to set the minutes past the hour to start the ventilation. Now, with the ventilation start time set, press the I/O button. The word “OFF” should appear to the right of the time
