Presentation


SGC universal solar heating controllers are intended for the regulation of solar systems for hot water production as well as a support system for room heating. Advanced operation algorithms ensure an optimal usage of solar energy and allow for the regulation of energy efficient circulation pumps. The SGC controllers have integrated preset hydraulic systems that allow a fast and simple installation.

Application SGC36HV


  • In hot water production systems with classic or vacuum collectors
  • In hot water production systems with additional heat sources
  • In supply device heating using solar heating system and additional heat sources
  • In pool heating systems
  • Single-stage supply device charging

 

Advantage SGC36HV


  • 53 preset hydraulic diagrams,
  • 2 free programmable outputs,
  • rotation speed control of 2 classical pumps (RMP),
  • rotation speed control of 2 energy-efficient pumps (PWM, 0–10 V),
  • system regulation with 2 collector fields,
  • system regulation with 3 heat storage tanks,
  • startup wizard for an easy and quick startup of the device,
  • measurement and display of the generated energy,
  • solar system protection by overheating of collectors,
  • diagnostics of operation by prompting to errors and exceeded temperatures,
  • the SeltronHome platform connectivity allowing remote control via smartphone or tablet.

OPTIONS FOR SWITCHING ON ADDITIONAL ENERGY SOURCES
The controller features the option of an auxiliary source for heating the water to the minimum temperature
    
The option for starting the primary energy source immediately or only when the water cannot be heated in a certain period of time
   
The option for configuring the time during which we allow water heating only by using collectors – the controller will not switch on the primary heat source if the calculations show that the water can be heated only by collectors
   
OPERATING MODES WITH MULTIPLE HOT WATER BUFFER TANKS
Constant operation in the “OPTIMUM” mode means an optimum use of solar energy for heating all of the storage tanks taking into account the preferred storage tank   
The "AUTO" operation mode automatically switches between winter and summer modes according to a preset calendar   
Constant operation in the “SUMMER” mode means the heating of only the preferred storage tank, other storage tanks are heated only when the preferred one reaches the desired temperature   
Continuous operation in the “WINTER” mode means an alternating parallel heating of all storage tanks   
Heating of all storage tanks
