The correct DIP switch settings for each zone module are:
• First Zone (1-4) Module:
• Second Zone (5-8) Module: 2 = ON position; 1, 3, and 4 = OFF position
• Third Zone (9-12) Module:
• Fourth Zone (13-16) Module: 4 = ON position; 1, 2, and 3 = OFF position
• If set to SYNC, zone synchronization is enabled.
5 • If set to NOT, zone synchronization is disabled.
• 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
6 position.
• 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
7 these zones.
• If set to 2-stage (ON position), then 2-stage operation is activated on thermostat
inputs. The zoning module operates as two 2-stage zones.
8 • If set to 1-stage (OFF position), then operates as four 1-stage zones.
