EU-L-12

L-12

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.

Why Choose the L-12?

• Efficient thermal energy management
• Full adaptation to daily needs and activities
• Wired or wireless communication between devices
• New wired communication with dedicated TECH SBUS devices
• Wi-Fi-L internet module included
• Remote control via the eModul app
• Supports up to 4 ML-12 slave units
• Heating/cooling function

How It Works?

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.

Remote Control

The L-12 unit is designed for remote system management via the eModul app, using the included Wi-Fi-L module.

Weekly Operating Schedules

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.

Operating Modes

The L-12 unit can operate in one of four selectable modes:

• Normal mode
• Holiday mode
• Economy mode
• Comfort mode

Multiple Options

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.

• Sensor - wired: 2-core cable
• Controller - wired: 4-core cable
• Controller or sensor - wireless
