Programming Notes
– In Express Setup set Load 1 for Setpoint; the Boiler Supply default setting is 130°F. Spa Heat Exchanger supply temperature range can be between 130°F-180°F (see note 2 p.1). Change Pump Post Purge (sec) to 180.– In Express Setup set Load 2 as Zone Of… and select Zone of Load 1.2

Wiring Notes
– No external voltages to be applied to TB2 control terminal strip connections 1-20. – Spa and Pool heating operation to be called for by contractor-supplied dedicated controllers, not by boiler sensors. – Pump circuits are fused for a total draw of 5A; maximum amperage draw of 4A is recommended.
