Thissetpoint is active in every control mode.DHWP SetpointThe Domestic How Water Priority (DHWP) Setpoint is active when DHW Input (DP) closes and“DHWP” parameter is set to “yes” and Local SP Mode is selected. When the contact is closed, thewater heater outlet is maintained at, or above, the DHW Setpoint.WWSD SetpointThe Warm Weather Shutdown (WWSD) Setpoint used to disable water heater and/or system pumpoperation when enabled by setting the “WWSD” parameter to “WWSD of Water heater”, “WWSD ofSys Pump” or “Both”Max SPThe Maximum Operational Setpoint for all possible Local and Remote Modes.Min SPThe Minimum Operational Setpoint is the lower limit for all Local and Remote modes.Min In H 2O Temp.Minimum Inlet Water Temperature Setpoint used as the Mixing Valve inlet temperature setpoint.Only visible when Mixing Valve equals Yes.Max H 2O Delta TMaximum Water Differential (Water heater Outlet minus Water heater Inlet) temperature setpoint usedas the Mixing Valve differential temperature setpoint.Only visible when Mixing Valve equals yes.Max Delta T HoldMaximum Water differential (Water heater Outlet minus Water heater Inlet) Temperature used to holdmodulation rate at low fire.56
