DUAL ZONE VENTILATION CONTROL MAKE UP AIR WITH SINGLE C-SENSOR
1. Exhaust appliance can be any voltage.
One lead on power supply to appliance
to pass though C-Sensor
2. Power is supplied by a line voltage
transformer matched to the power
source voltage to step down to 24VAC.
VA Rating of transformer to be
sufficient to maintain the DPDT 24VAC
relay. This transformer will provide
isolation from either zone in addition to make up air activity
will be
available if one zone is disabled or disconnected for
service. This also aids to reduce current draw from the
HVAC system if the additional relay load is to large.
3. 24VAC DPDT relay is used to maintain circuit isolation
between Zone 1 and Zone 2.
4. Current from appliance will activate C-Sensor and DPDT relay. Both HHSC+ controls on each zone will be operating on
remote control causing the central fan on each zone to be operating. Dampers on each zone will also be open.
