HOMEOWNER (USER) SETTINGS
The Homeowner Menu items (dark green Map item boxes) are directly available under normal operation, and
are accessed simply by pressing the MENU button while at the home screen window, or from the Daylight
Savings menu window in the Contractor Setup menu. It is not necessary to press MENU and SELECT to enter
the Homeowner Settings menus. The Homeowner Menu items are intended to be the main features of interest
by the occupants, while the Contractor Setup Menu items are intended to be accessed only by those installing the
HHSC+.
SYSTEM ON/OFF
Setting this parameter to “Off” will terminate all input and output functions of the HHSC+, except for the
time/date display, and the status LED will not be lit. The HVAC system will continue to operate normally,
with complete control of the system by the thermostat allowed, including manual fan on/auto control at the
thermostat. The HHSC+ will continue to be internally powered, in order to maintain the time, date, and UV
and filter replacement timers. All HHSC+ settings are retained in “flash” memory; no external or internal
battery power is required to maintain the HHSC+ settings. When the HHSC+ System is set back to “On”,
the HHSC+ will resume all normal functions with all settings as they were before the HHSC+ was turned off.
CLOCK/CALENDAR SET
Press SELECT to set the clock hour (AM and PM), again to set the minutes, and so forth to set the month,
day, and year. While it is not necessary for the date to be correct for maintenance of the UV and Filter
timers, setting the correct date will result in the automatic Daylight Savings time corrections (if enabled)
to occur on the correct dates. This will preserve proper timing of the Inhibit Mode timing (if enabled)
throughout the year, automatically.
INHIBIT MODE
This feature allows the occupants to set a daily period in which the HHSC+ will be prohibited from causing
the HVAC system fan to run according to the programmed Ventilate, Circulate, and Cycle Period settings,
while allowing full control of the HVAC system solely by the thermostat. As a result, the average rates of
circulation and fresh air ventilation may be reduced during this period.
While use of this feature may violate some ventilation code requirements, the fresh air rate actually required
for adequate ventilation is typically greatly reduced during this time, such as when the occupants are resting
or absent and no activity is occurring in the house.
To set and activate the Inhibit Mode, press the SELECT button to enter the programming windows. First set
the hour and minute for the time of day/night that the inhibit period is desired to begin. Press SELECT again
to set the duration (in hours) of time for which the HHSC+ is desired to be inhibited from activating the
HVAC fan. For instance, if the inhibit period is desired to be from 10:30 PM to 6:30 AM, set “Inhibit Start”
to 10:30 PM, and “System Inhibit Duration” to 8 hours.
If “System Inhibit Duration” is set to zero (factory default), Inhibit Mode will be automatically disabled.
FAN CYCLE PERIOD
The Fan Cycle Period menu item allows the occupant(s) to select the desired cycle period, or how often the
HHSC+ will activate the system by itself, as when the thermostat may be satisfied for long periods. The
available selections are 30, 45, and 60 minutes. This feature is also found in the contractor setup menu
item as Cycle Period; changing the cycle period in either menu item will have the same effect.
NOTE: Changing the Fan Cycle Period will not affect the average fresh air ventilation rate, which is solely
controlled by the Ventilation % setting. It may be freely changed without altering the effective ventilation as
required to meet a given ventilation standard.
