    NSTALLATION AND PERATION ANUAL ClimaticControl-HC Heating & Cooling Controller IMPORTANT! Before starting work the installer should carefully read this Installation & Operation Manual, and make sure all in- structions contained therein are understood and observed. ClimaticControl-HC should be mounted, operated and maintained by specially trained personnel only. Personnel in the course of training are only allowed to handle the product under the supervision of an experienced fitter.

  • Page 3: Application

    1. Application  ClimaticControl-HC is developed for variable flow temperature control in heating and cooling systems particular in low-temperature installations like floor heating and cooling systems. The flow temperature is controlled de- pending of the outside temperature following a curve. Using the ClimaticControl-HC the operation of a water floor system can be adapted to the actual demands of the ...

  • Page 15 AUTOMATIC mode of operation Automatic mode of operation using the built-in or user programs. The ClimaticControl-HC is controlled according to the selected built-in or user program ( 6.2.). The flow temperature is controlled depending on the outdoor temperature and the curve with room com- pensation if RF thermostat is installed.

  • Page 16: Program Mode

    STOP mode This mode is used to switch off the system. The device switches off the system. The ClimaticControl-HC software version is indicated on the display for about 3 seconds and then switches off (no indications). By pressing any of the keys the ClimaticControl-HC can be switched on. REMARK: When the ClimaticControl-HC is in STOP mode, In Heating mode only an Anti-freeze function can restart heat relay and circulation pump to maintain the water temperature above 10°C.
