EU-L-8e

L-8e

The L-8e is a wireless thermostatic valve controller designed for managing both underfloor and radiator heating systems.
The L-8e control unit efficiently manages thermoelectric actuators on valves as well as wireless actuators such as the STT-868 or STT-869.

Why choose the L-8e?

• Manage radiator and underfloor heating from a single integrated system
• Conveniently adjust operating parameters in up to 8 rooms
• Wide compatibility with various devices
• Visible energy savings through intelligent control
• Remote management via the internet module

How does it work?

The controller is designed to operate both wired and wireless valve actuators via a radio signal. The complete system ensures optimal temperature control across 8 heating zones. The L-8e controller can manage up to 50 thermo-electric actuators through 22 outputs, using wireless room thermostats and wireless temperature sensors.

Key features:

• Wireless communication
• Supports 8 zones/rooms
• Underfloor heating pump control
• Volt-free contact for heating device connection
• Heating/Cooling mode

Remote control

The L-8 control unit is compatible with the ST-505 Internet Module and the WiFi RS Module.
The WiFi RS module uses a wireless connection, while the ST-505 requires a wired connection to a router via an RJ45 Ethernet cable.

Operating modes

The device can operate in one of four selectable modes:

• Normal mode
• Vacation mode
• Economy mode
• Comfort mode

Weekly schedules for both heating and cooling

Users who want to save time can predefine the desired temperature levels for each zone — individually or collectively across all zones.

• Local schedule – a weekly program assigned to a specific zone.

• Global schedule – applies the same temperature settings to all zones simultaneously.

In addition to scheduling, the user can also set a constant temperature or a temperature with a time limit.

Easy to install and convenient to use

The L-8 controller is a surface-mounted device that can be easily installed on a DIN rail.
Its large, clear display allows for quick temperature checks and easy monitoring of other system parameters.
