DHW (Domestic Hot Water)
To navigate to the DHW Screen, touch the DHW faucet icon on the Configure Screen.
DHW has all the same parameters as CH1 and CH2 with one exception. DHW has the following additional
parameters for adjustment:
• DHW Offset – Upon a DHW heat demand, the unit will control the outlet temperature to the DHW Set Point plus the
DHW Offset (set point + DHW Offset).
For example, with a DHW Set Point of 140°F and a DHW Offset of 40°F, the unit will control the boiler outlet
temperature to 180°F (140°F + 40°F) to satisfy the heat demand.
NOTE: A DHW heat
demand can be initiated by
an aquastat or sensor, see
Section 7.E.3 on page 41
