HEALTHY HOME SYSTEM
The Field Controls Healthy Home System™ Controller Plus (HHSC+) is designed to work in conjunction with
the forced air HVAC system to periodically introduce fresh air into the home by controlling an FAD Fresh Air
Damper installed in a fresh air duct connected to the HVAC return plenum, and circulate it throughout the
home effectively and efficiently, and enables the HVAC system to meet ASHRAE 62.2 and other ventilation
codes and standards.. The HHSC+ is designed to operate continuously year round without user intervention.
The HHSC+ is initially programed by the installer and operates interactively with the HVAC system thermostat.
Certain features are readily accessible by the occupants for customization of the system, to meet their individual
preferences.
ITEMS INCLUDED IN KIT:
1-HHSC+ Ventilation and Fan Cycling Control
1-Four-wire connector harness for FAD Fresh Air Damper (FAD not included)
1-Installation Hardware
1-Instruction Booklet

  • Page 3: Installation

    INSTALLATION CHOOSE FAD FRESH AIR DAMPER LOCATION: The fresh air damper can be located anywhere in the fresh air inlet duct. Minimize the length of the inlet duct to improve airflow and improve system efficiency. It is recommended that the damper be as close to the return air plenum and the HHSC+ as possible, and that the inlet duct connect to the return plenum upstream of the system filter, and downstream of any duct-mounted sensors.

  • Page 4: How To Install The Controller

    INSTALLATION (con’t) HOW TO INSTALL DAMPER: The damper may be installed in any position; although it is recommended to install with the motor at the 3 or 9 o’clock position if mounted horizontally. Air may flow through in either direction, although it is recommended to install with the crimped end as the outlet of the damper.

  • Page 7 OPTIONAL EXHAUST FAN CONTROL: The HHSC+ may optionally control an exhaust fan (not included) using the AUXC and AUXO auxiliary output terminals (wiring to thermostat and HVAC unit not shown for clarity) on the base. Connect the terminals to a 24 VAC relay (not included, 1A max. current) to control a 120 VAC exhaust fan. Whenever ventilation is occurring (the FAD damper is opened), these terminals will be energized and the fan relay will activate the exhaust fan to work in conjunction with the Healthy Home System to provide balanced ventilation.

    SETUP NAVIGATING THE MENU Please refer to the color-coded Menu Map for guidance through the HHSC+ menu structure. Each colored box on the Map represents a particular menu item window that will appear on the HHSC+ display. The button colors, shapes, and action arrows in a Map item box correspond to the actions and settings available in the corresponding display menu item window.

Measure the actual flow rate through the fresh air duct using a flow hood, anemometer, or Pitot tube and manometer, with the HVAC fan running on lowest speed and the FAD damper open (temporarily jumper AUX-IN to R terminal, or activate remote override device if connected): Example: 140 cfm measured.
