3.4 System Configuration
See Page 6, Figure 4 for details. Below the ribbon cable J2 connector, there are six configurable jump- ers. They indicate whether the thermostat for each zone uses an anticipator. If the thermostat for that associated zone has an anticipator, then use a jumper to cover both pins for that zone. If the thermo- stat for the associated zone does not use an antici- pator, then cover the right side pin only.
The bottom two jumpers are associated with Pump 2 operation. They indicate whether Pump 2 is active and which zones are associated with it. Pump 2 can only be associated with Zone 3 and/or Zone 4. To enable Pump 2, use a jumper to cover both pins for the zone(s) that will operate on Pump 2. To disable Pump 2, cover only the right side of the pin of zone 3 and 4.
All pump motors are equipped with thermal overloads.
3.3.3If an outside air blower is to be used with any of the above options, See Page 10, Figure 8.
