This is a universal thermostatic valve controller designed for managing underfloor heating. The L-12 unit controls the thermoelectric actuators installed on the valves. In a mixed system, it can also manage wireless electric actuators such as G-X or STT-869.
The L-12 unit allows control of up to 50 electric actuators, manages the heating device, supports surface cooling, and controls the underfloor heating pump. A mixing valve can be operated using an additional module. With intelligent room control, thermal comfort is maintained while avoiding excessive energy consumption.
The L-12 unit is designed for remote system management via the eModul app, using the included Wi-Fi-L module.
In each zone, users can set up to 6 weekly schedules: 1 local and 5 global.
Local schedule – assigned to a single zone.
Global schedule – applies the same temperature settings across all zones.
In addition to schedules, users can set a fixed target temperature or a temperature that applies only during a specific, defined period.
The L-12 unit can operate in one of four selectable modes:
hanks to the built-in radio module in the L-12 unit, the system offers multiple communication options. Communication between measuring devices (sensor or controller) can be either wired or wireless.
L-12 unit + up to 4 ML-12 units (supports up to 40 rooms)
