DEVICE DESCRIPTION

The EU-ML-4X WiFi floor heating extension module is designed to operate with the EU-L-4X WiFi controller.
It allows for an extension of the floor heating system through the addition of 4 zones via the use of either wireless sensors and controllers, or the wired RS-485 (TECH SBUS) controllers connected to/registered with the EU-L-4X WiFi controller.
It employs thermoelectric actuators, e.g. STT-230/2 T, STT-230/2 M.

Devices for the expansion of the system are updated on an ongoing basis on our website www.tech-controllers.com

INSTALLATION

WARNING

The module should be installed by a qualified person.
