CURRENT-SENSING MAKEUP AIR

SENSOR

Model: C-Sensor

The C-Sensor Electronic Makeup Air Sensor is intended for use as an accessory to the HHSC+ Ventilation

Control and FAD fresh air damper system, and/or optional E-Sensor Enthalpy Damper Control or T-Sensor

Temperature Damper Control (items not included). The C-Sensor senses the operation of air-exhausting devices

(such as range hoods, dryers, bathroom fans, central vacuum systems etc.), and acts as a switch to provide

a 24 VAC input signal to the HHSC+ Ventilation Control, which then operates the FAD fresh air damper and

activates the HVAC central fan, to draw air into the house and provide makeup air for the exhausting device.

The C-Sensor may also be used in a stand alone makeup air system to control a 24V fresh air damper.

ITEMS INCLUDED IN KIT:

(1) Model C-Sensor Electronic Makeup Air Sensor, with electrical junction box

(2) wiring strain reliefs

(1) Envelope containing TVS Diode

INSTALLER-SUPPLIED ITEMS:

• 24V wiring (min. 22 AWG, max. 50’, min. 18 AWG, max 150’)

• Wiring connectors

INSTALLATION 1. Install the HHSC+ Ventilation Control, and low-voltage wiring tothe Makeup Air Sensor: Follow the instructions for installation included with the HHSC+ and refer to Wiring Diagrams below to determine the desired wiring configuration. Avoid routing the low-voltage wiring near line-voltage circuits and highcurrent devices.

TROUBLESHOOTING • Neither red nor green LED on the Makeup Air Sensor glows when the exhausting appliance is operating: check that only one current-carrying wire to the device is passed through the hole in the Sensor. If this is correct, loop another turn of the wire through the hole in the Sensor. The Sensor will gain sensitivity with every extra loop of wire passing through the hole.
