2-Stage T/S Output Heat-Capacity (P.11)
Models with the 2-stage air handler control function (W1, W2) can
use a 2-stage thermostat or can be automatically controlled by the
H2Air+

controller (If the DIP switch # 3 is OFF).
When using the automatic 2-stage heating feature, the system will
modulate between the 1-stage and 2-stage based on the set heat
capacity parameter of the water heater. This heat capacity value
can be adjusted based on the desired modulation point (default
heat capacity is 25%)

1. In the Parameter information time mode, use the Up (+) or
Down (-) buttons to select P.11. Then, press the Info button to
enter 2-stage T/S output heat-capacity mode.
2. In the 2 stage T/S output heat-capacity mode, use the Up (+)
or Down (-) buttons to change the value and press the Info
button to set to the desired mode.
