6.4Status

The operator can monitor the percentage heating, cooling, dehumidifying and humidifying status of the unit by selecting the “STATUS” sub-menu.

6.5Active Alarms

The operator can monitor the alarms status by selecting “ALARMS” which will display a “No Alarm Present” or “Alarm XX of YY” alert and description. If more than one alarm is activated, use the UP or DOWN arrow to scroll through the alarms list. (“XX” reference is the number of the alarm shown, while the “YY” reference is the total number of alarms activated).

6.6Time

The controller time clock must be set to allow for the setback control. The clock uses the 24-hour system (i.e., midnight is entered as 24:00). To change the time press Enter to select the function, then use the Up and Down arrows to change the first character, press Enter to store, then press the Up or Down arrows to change the character, press Enter to store, etc. THERE IS A BATTERY BACKUP FOR THE DATE AND TIME FEATURES.

6.7Date

The controller date must be set to allow for setback control. To change the date press Enter, then use the Up and Down arrows to change the first character, press enter to store, press the Up and Down arrows to change the second character, etc.

6.8Setback

The microprocessor can be programmed for night and weekend setback. Two (2) events can be programmed for a five-day work week and two (2) events can be programmed for a two-day weekend. The following table can be used to devise a setback plan.
