intech 21 HWHC2100 Operation Manual

The Hot Water Heating Controller HWHC2100 (Fig 1) provides control of the Building's mixing valve, heat
exchange valve or the burner operations to regulate the heating water temperature or the amount of thermal energy
supplied to the Building. The HWHC2100 adjusts the temperature of the heating water, calculating the target
temperature, in response to changes to the outdoor temperature. The HWHC2100 controls the motorized valve and the
circulation pumps. Alternatively, the control could be provided directly to the burner operations.
In Auto mode the HWHC2100 distributes heat energy entering in the building in accordance with weather,
outdoor temperature and installed parameters. Depending on the controller's configuration the main parameter of the
regulation could be either the hot water in house input the supply temperature (system water temperature) or condensate
return temperature (return water temperature).
HWHC2100 works as a standalone controller and can be connected to a Local Server, which provides additional
parameters adjustments to HWHC2100 based on apartment's indoor real time temperature. This feature will improve the
heating supply and distribution efficiency and can eliminate the apartments over or under heating. When the HWHC2100
is connected to the Local Server it can be monitored and controlled from the local Intranet and/or Internet with
appropriate authentication.
