Elfatherm E 8.1124 Extension module

The Elfatherm E8 heating controller is a weather and room-controlled controller for panel or boiler installation in a standard 144 x 96 mm housing, with interface for CAN bus and optical interface for PC connection. A special feature of the successor controller to the E6 is the backlit display with plain text display and the associated quick and easy programming. The new E8 controllers can be operated with either 1 kOhm PTC or 5 kOhm NTC sensors. However, 5 kOhm sensors are preferable for new installations. The functionality of the E8 series can be extended to up to 15 mixer circuits with the E8.1121 extension module. The E8.1121 is connected to a heating controller (e.g. E8.0631) via the communication interface. Each E8.1121 expansion module controls a maximum of 2 independent mixer circuits. * The E8.1121 can operate as an independent mixer circuit controller without connection to other E8 devices. This requires the connection of an external sensor. It is supplied without sensor and connection set and must be ordered separately if required.
