NOTES:
• Air Valve Min% Modulation (1) set by Adj2 Pot (R4 on right)
- Range: 0% (CCW) to 50% (CW)
- Factory set to 0% (Full CCW)
• Air Valve Heat% Modulation (2) set by Adj1 Pot (R8 on left)
- Range: Min% (CCW) to 100% (CW)
- Factory set to 100% (Full CW)
• There is a 7% Deadband in the Heating Demand input, which
gives the appearance of overlap in the ranges.
• Cool LED turns On when Cooling Demand exceeds 17%
• Fan LED turns On when Air Valve modulation exceeds 35%
• Heat LED blinks during lower Heat Demand until WV is fully open
