6.3I Intermittent or Programmed Ventilation

FOR HVAC INSTALLER ONLY AND HOMEOWNER

6.3I Intermittent or Programmed Ventilation

With the damper in program mode (denoted by “Pr” when setting the damper operation) the system will operate the ventilation function according to the current ventilation program.

There are 4 programs available for ventilation Monday through Friday. There are also 4 programs for Saturday and 4 programs for Sunday. No other choice of days is available. Each program to be used has an “on event” called “START” which brings the ventilation function on, and an “off event” called “STOP” which turns the function off. Each START and STOP must be entered in to the controller.

To set or adjust the ventilation program:

9.Pressing the “PROG” button again to move onto “program 2/stop” and begin the process again if setting the other programs. Follow the same procedure for each program.

10.To end the program process simply leave the control alone (don’t push any buttons) for about 10 seconds. The unit will remember any changes and return to “home state”.

5.3J Programming Notes

To run the ventilation program, the damper mode must be in the “program” mode (“Pr”).

The timer can be operated manually without changing the program by adjusting the damper mode from “program” to either “on” or “off”.

To delete a program after it has been entered, adjust the program so the “START” and “STOP” times are identical.

Occupants should determine ventilation times and rates. Therma- Stor LLC makes no firm recommendations concerning when to ventilate. Common ventilation schedules include constant ventilation, ventilation based on occupancy times, intermittent operation, and seasonal ventilation.

Remember the control must be on for the unit to be functioning - make sure the green power indicator “ON” is lit.

1.Press the “PROG” button two times. The display will indicate “Program 1/start” at the bottom, and the hour display will flash.

2.Use the “SET” + or – button to adjust the hour for the Program 1 start time. Be sure to pay attention to the am/pm setting.

3.Press the “PROG” button again. The display will indicate “Program 1/start” at the bottom, and now the minute display will flash.

4.Use the “SET” + or – buttons to adjust to the desired minute setting.

5.Press the “PROG” button again to move on to the “Program 1/stop” event. The display will indicate “Program 1/stop” at the bottom, and the hour display will flash.

6.Use the “SET” + or – button to adjust the hour for the Program 1 stop time. Be sure to pay attention to the am/pm setting.

7.Press the “PROG” button again. The display will indicate “Program 1/stop” at the bottom, and now the minute display will flash.

8.Use the “SET” + or – buttons to adjust to the desired minute setting.

5.3K Ventilating or Dehumidifying to Control Indoor Relative Humidity Levels

Fresh air ventilation may have a drying effect or a wetting effect on the indoor space, depending on the amount of moisture present in the outdoor air. Relative humidity is not a good indicator of outside humidity levels: use dew point measurements instead. Consider outside humidity levels when using the ventilation function of the dehumidifier.

5.3L Stop Start

During summer in hot, humid climates operating in ventilation mode will increase the moisture load in the home.

Consider reducing the amount or frequency of fresh air ventilation if indoor humidity continues to be high.

5.3M Low Pressure Control

If the low side refrigerant pressure drops to 15 PSIG, the low- pressure control opens and shuts off the compressor and impeller fan. It is an automatically reset control. It will close when the refrigerant pressure rises to 35 PSIG. Its primary function is to prevent damage to the compressor if a leak develops in the refrigeration system. It may also open if the unit is A) installed in a cool area (below 50 F) or B) installed where it is below 40 F and then started. Under these conditions, the unit will restart within several minutes. Until the unit warms up, it may cycle several times.
