Operation Manual 

 

1. Introduction 

 

 

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.

                                                          The HWHC2100 features: 

 

 

Configurable to controls the zone valve or boilers to regulate the circulated water temperature.  

 

Adaptable to different type of actuators: floating point, 4-20mA, 0– 5V, 0–10V or 135ohm input. 

 

Automatic positioning of the zone valve or adjusting the boilers stages in accordance with operation settings and 
measured temperatures. 

 

Manual Control Mode. 

 

Displays the valve position circulation pumps and/or boilers status. 

 

Day and Night modes of operation with programmable time durations. 

 

Programmable heating season dates. 

 

Flexible selection of the feedback control temperature source (system (supply) or return). 

 

Extended Heat-Up period up to 100 minutes with step of 1 min.
