5.2B Setting

During the set-up process, if you make a mistake, you can always go back to adjust the settings. If you leave the control alone and don’t touch any buttons for 10 seconds, the con- trol will remember any changes made and return to “home state.”

5.2C On/Off Setting

Press the “ON/OFF” button to turn the system on or off. When the system is on, the green indicator will be lit. In the off mode, the controller continues the regular display sequence and indicates current time, temperature, and relative humidity. It also displays the status of the fan and damper as if the control were on, but the fan and damper will not operate unless the control is on and the green indicator is lit. Setup can be done with the control either on or off.

5.2E Setting Relative Humidity Setpoint

The relative humidity setpoint operates the dehumidifier function of the Ultra-Aire. It has no effect on any other func- tion of the unit. The control senses the ambient relative humidity of the space in which it is located. The ambient con- dition is displayed on the right in the relative humidity display sequence, under the word “HUMIDITY”. The current setpoint is displayed on the left, under the word “SET”.

Figure 3: DEH 2000 Clock DIsplay

If the setpoint is equal to or greater than the current ambient condition, the space does not need to be dried, so the dehu- midifier function will be off. Example: Setpoint: 50% RH Current condition 45% RH = Dehumidifier off, red “DEHU” indicator not lit.

If the setpoint is less than the ambient condition, the dehumidifier will be on, and the red “DEHU” indicator will be lit. The space is more humid than the setpoint, so the con- troller operates the dehumidifier to dry the space. Example: Setpoint: 50% RH Current condition: 55% RH = Dehumidifier on, red “DEHU” indicator lit.

To set the relative humidity setpoint, press the “HUM” button. The display will show the “HUMIDITY” display, and the word “SET” will flash. Use the “SET” + or – buttons to adjust the relative humidity setpoint as desired. Therma-Stor Products recommends relative humidity levels of 45% in the summer, and lower levels in the winter. It is not recommended the humidity setpoint be set below 35%. In order to dry the home in the winter in a cold climate, use the ventilation function of the system rather than the dehumidifier function.
