HEAT REGULATOR EHEAT 130 PLC

The eHeat thermostat is freely configurable via a web browser, touch screen, or the controller's own display. It is an intelligent thermostat that can be optimized according to system and environmental conditions. IO points can be expanded as needed. The controller also features weather forecasting control and demand-response functionality. eHeat131 controller - heating distribution controller (e.g., single-family homes, low-rise apartments, row houses) - compatible with eHeat124 - eHeat131 is designed for 3-circuit heating distribution applications - eHeat131 is a module component for DIN rail mounting (8 modules) - eHeat131 is ordered as a separate product and installed manually into the enclosure Additional options - eHeat131 can be supplemented with additional IO via eHeat124 - eHeat131 can also be ordered as eHeat131 + 2 pcs. eHeat124 additional IO, enabling up to 5 heating circuits. In this solution, components must be installed manually into an enclosure or a suitable enclosure must be requested. Functional features - domestic hot water control based on a fixed setpoint determined by supply water temperature - heating network control via 5-point control curve, fixed setpoint, or supply water setpoint provided via cloud service - heating network control also possible via fixed outdoor temperature setpoint - outdoor temperature measurement locally, manually, or as a value provided via the bus - sensor fault alarm in all temperature measurements - adjustable control deviation alarms in network supply water measurements - network pump fault alarms - network pump shutdown when no heating demand exists, with weekly cycling of pumps and control valves during shutdown periods - network pressure measurements or pressure alarms - district heating supply and return temperature measurements - cold water metering and leak alarm - upper and lower limit alarms for district heating inlet temperature and network pressure measurements - network pump control conflict alarms - energy meter connection via bus (Kamstrup) - pump connection via bus (Grundfos) - domestic hot water tank charging Other features - clear graphical display and five buttons - Ethernet RJ45 connector (not eHeat120M) - 2 x RS485 bus - SD memory card slot - connectable to monitoring systems or cloud services - freely configurable IO - widely compatible sensors - 1 x pulse counter - Modbus RTU (optionally MS/TP) Ethernet features - email alerts - WebVisu - Modbus TCP/IP (optionally BACnet IP) IO points - 12 x relay output - 12 x digital input - 12 x analog input - 6 x analog output This product description is an automated translation of the original Finnish description.
