The Healthy Home System™ Control utilizes these sensors to monitor and respond to changes in temperature, humidity, and/or changes in air pressure. The contractor may customize ventilation operations based on the home’s design, the homeowners’ preferences, or the need for more or less fresh air.
The C-Sensor senses the operation of air-exhausting devices, such as range hoods, clothes dryers, bathroom fans, central vacuum systems, etc. It acts as a switch to provide a 24 VAC input signal to the HHSC+ Ventilation Control, which then operates the fresh air damper (FAD) and activates the HVAC central fan. Fresh, outside air is then drawn into the house, providing make-up air for the exhausting device(s).
The C-Sensor may also be used in a stand-alone make-up air system to control a 24V fresh air damper.
The Field Controls T-Sensor Outdoor Temperature Damper Control prevents outdoor air from being pulled into the home when outdoor weather conditions are too hot or too cold.
The T-Sensor and HHSC+ provide make-up air to the home on demand or automatically when triggered by a variety of sensors, switches, and other equipment. The T-Sensor mounts to the fresh air ventilation duct, between the FAD and the air intake hood or termination.
The Field Controls E-Sensor Enthalpy Damper Control senses humidity as well as extreme temperatures and prevents outdoor air from being pulled into the home when appropriate.
The E-Sensor and HHSC+ also provide make-up air to the home on demand or automatically when triggered by a variety of other monitoring equipment. The make-up air function may or may not override the E-Sensor ventilation-inhibiting function. The possibility of such conflicts will depend on the wiring configuration chosen by the installer.
The P-Sensor senses a change in air pressure within the exhaust duct of an exhausting device, such as a kitchen range hood, clothes dryer, central exhaust system, etc.
It transmits a signal to a make-up air system, such as the HHSC+ ventilation system, in order to provide make-up air for the exhausting device. The P-Sensor may also be used in a stand-alone passive make-up air system to control a 24V fresh air damper (FAD) that is ducted to the exterior of the structure.
