How To - Assign Zones
How to Assign Zones on the Control Board?
Assign the thermostat zones for each pump by moving the jumper to the correct zone #.
Each pump has its own section of the control board, labeled 1-10. Pump 10 is always to the heat source. The other pumps may be assigned to specific zones by moving the jumper to the pins labeled with that zone #.
All pumps are initially assigned to zone 1, except pump 10. It is pre-assigned to all 4 zones. (You can skip this step if you only have 1 thermostat)
