Pressing this button will write default values of all temperature programs and setup menus into the unit’s nonvolatile memory. Take care not to unintentionally press this button when the thermostat has been removed from the wall plate!
4.4. PROGRAMMING
You can change the preset time/and temperatures to suit your schedule for each day of the week. Each day has four consecutive periods. They are Morning, Day, Evening, and Night. Separate set points are provided for Heat and Cool.
Fan programming is similar to temperature program- ming. It has four consecutive periods, which are inde- pendent of the four temperature periods. The default set- ting for your systems fan requires it to run only as required by your environmental system. It may be pro- grammed to maintain a minimum run time on an hourly basis, or run continuously.
4.4.1 WEEKDAY TEMPERATURE PROGRAMMING
●Rotate the dial to Set Weekday Programs. The heat and cool set points will be displayed on the left side of the display. The start time for the displayed day will flash to show that this is the setting currently ready for edit.
●Use the up or down arrow keys to change the start time for this period. One period ends at the start time of the next period. The beginning of that period may not be any closer to the beginning of the next period than one 15 minute increment.
●Press NEXT to accept the displayed start time and advance to edit the heat set point. It will be flashing.
●Use the up or down arrow keys to change Heat Set to the temperature you desire.
●Press NEXT to accept the displayed heat set point to the temperature and advance to edit the cool set point. It will be flashing.
●There is a minimum value that must be maintained between the heat temperature set point and Cool temper- ature set point. The value that must be maintained is called the Deadband. It is programmable and may be changed in the Installer Setup menu. If you move the heat set point temperature to close to the cool set point temperature the cool set point temperature will move away from the heat set point temperature to maintain the dead band. Conversely the heat set point temperature will move if you adjust the cool set point temperature to close. There are programmable limits for both heat and cool, which you will not be able to exceed. These values are accessible from the User Setup Menu.
●When you have changed the Cool set point to your desired temperature, press NEXT to advance to the next period. Its start time will be flashing indicating that it is under edit.
●When all the periods for a day have been set, the start time for the next weekday will be displayed to begin edit-
ing the settings for that day.
●Rotate the dial back to RUN to and accept all current values and end the programming session.
4.4.2 WEEKDAY FAN PROGRAMMING Programming fan operation is similar to programming the temperature periods and set points. Fan periods are independent of temperature periods and are designated P1, P2, P3, P4.
●Rotate the dial to Set Weekday Programs, then press and hold the FAN button for over 2 seconds.
●The fan day and period will be displayed in the top center and right portion of the screen. The bottom por- tion will show the fan mode and start time for that period. The fan mode for this period will be flashing to indicate that it may be changed with the UP/DOWN arrow keys. Choices are:
■Auto: default value; the fan will run only when neces- sary for your HVAC system to maintain temperature con- trol.
■Program: This mode will insure that during every hour, the fan will run for the for at least the number of minutes shown at the top left of the display, beginning at the displayed time for this period until the beginning of the next period. If your heating or cooling requirement fulfills the minimum fan run time, additional fan run time will not be requested. Activation of the fan when neces- sary is done at twenty minute intervals for one third the hourly run time.
■On: The On setting will run the fan continuously dur- ing this period.
●Set the desired Fan mode for his period. Press NEXT to advance and edit this periods start time.
●Use the UP or DOWN arrow keys to change the start time. A period ends at the start time of the next period. The beginning of a period may not be any closer to the beginning of the next period than one 15 minute incre- ment.
●Press NEXT to advance and set the minimum fan run time if this period is to use program mode.
●Pressing NEXT again will bring you to the next period’s mode.
●When all the periods for a day have been set, the start time for the next weekday will be displayed to begin edit- ing the settings for that day.
●The sequence of days that you may program pro- gresses the weekdays MON - FRI, and repeats.
●Then press and hold the FAN button for over 2 sec- onds to return to Weekday temperature editing or rotate the dial back to RUN to and accept all current values and end the programming session.
4.4.3 WEEKEND PROGRAMMING
Weekend programming is identical to weekday program- ming except rotate the dial to set weekend programs, and the sequence of days that you may program is SAT, SUN and then repeating this two day sequence.
