If you need a for CAREL to talk to a BMS (like Niagara, Siemens, or Tridium), mention the controller model (e.g., pCO5+, pCOsistema, Power+).
You cannot use 1Tool v1.5 to program a pCO5+ controller. Check your controller’s label. For pCOe (small white controller), you need pCOStudio. For old pCO2, you need the legacy 1Tool Configurator. download 1tool carel link
