Application
For the control of warm-water (floor) heating systems and direct electric heating systems used in Commercial buildings, Residential buildings, Light industrial buildings.

Features
Touch-screen operating interface
7-day programmable function for energy-saving operation
On/off control output for heating device
Symbol indicator when heating is on
