For constant fan operation place the FAN jumper (I) on the center and upper pins on ON. Opposing Call Changeover The GEN II-R controllers are configured at the factory for Opposing Call Changeover with a time delay setting of 10 minutes. With this configuration, any number of thermostats can make a like active call (heat or cool). - Page 20 2 WIRE ZONE DAMPERS Zonex Systems zone dampers are used in cooling / heating systems to provide room by room zone control. The damper is provided with a zone actuator. Each zone damper is controlled by a zone thermostat. More than one damper can be controlled by one zone thermostat.
- Page 21 ROUND MEDIUM PRESSURE ZONE DAMPERS Zonex Systems round medium pressure zone dampers are recom- mended for systems with a maximum differantial static pressure up to 1.75”. This power open / power closed damper is manufactured from 20-22 gauge galvanized steel with rolled-in stiffening beads for superior rigidity.
- Page 22 MOTOR RECTANGULAR HEAVY DUTY ZONE DAMPERS (STCRX) Zonex Systems rectangular heavy duty dampers are recommended for systems 5 tons or larger with a maximum differential static psure of 1.75”. These are power open / power closed dampers made of 20 gauge “snaplock” steel frame with S & Drive duct connections.

Page 23: Sizing
DAMPER TRANSFORMER SIZING The 24V transformer connected to TR1 and TR2 of the GEN II-R System Controller powers the zone dampers. The power rating of the transformer must be sufficient to power the number of dampers used. Also, a properly rated in line fuse must be used on the secondary of the transformer. -

INTEGRATED PRESSURE CONTROL SETUP BYPASS DAMPER with INTEGRATED PRESSURE CONTROL (Part # STBP or STCDBP) Bypass Damper with Integrated Pressure Control is used to control bypass operations. The bypass damper modulates to maintain static pressure as zone dampers open and close. The bypass system reduces air noise from the supply registers caused by excessive air velocity. - Page 30 INTEGRATED PRESSURE CONTROL SETUP Static Pressure Option: The Integrated Pressure BYPASS CHECKOUT FOR STATIC PRESSURE Control Board can be field configured for specified CONTROLLER static pressure using a multi meter and the static pressure – voltage chart.
