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.
