• If set to NOT, zone synchronization is disabled.
6 • If zone valves are normally closed (N.C.), set the NC/NO DIP switch to the Off
position.
• If zone valves are normally open (N.O.), set the NC/NO DIP switch to the On
position.
7 • If set to Group (ON position), the AUX Pump contacts on the Control Module are
switched when any of the zones on this Zoning Module are active.
• If set to - (OFF position), the AUX Pump contacts are not affected by activity on
these zones.
