Where to buy?

Description

Optimal Utilization of PV Installation Energy

Charging of the hot water tank or central heating buffer outside of schedule with limited power
Energy meter and excessive consumption prevention
Weather-based controller with automatic response to outdoor temperature changes ensures the most energy-efficient operation
Ability to program room temperatures on daily and weekly cycles
Option to regulate water temperature in the domestic hot water tank and activate the circulation pump according to set daily and weekly programs

Versatility and Efficiency

Compatible with any central heating system and domestic hot water exchanger
Circulation pump, 5-liter diaphragm expansion vessel (EKCO.MN3), and necessary safety equipment included
Low heating costs thanks to heat accumulation during cheap energy tariffs - cooperation with central heating buffer when using appropriate modules (see additional equipment)

Advanced Features

Outdoor weather sensor and indoor room sensor included
Possibility to expand the system with additional heating circuits (C.MG3 modules)
Cascading capability for multiple units
Remote operation via internet using a dedicated application (with additional C.MI2 module)

Optional equipment

Product code	Description
C.MI2	The C.MI2 internet module enables remote control of boiler operation via the internet using a computer, tablet, or smartphone. Control is facilitated through a dedicated application (Android/iOS) or a web browser, ensuring easy and intuitive operation while leveraging all advanced features of the M3 controller.
C.MG3	The C.MG3 module, when connected to a central heating boiler and a 3-way mixing valve with an actuator, allows for the control of an additional heating circuit (e.g., underfloor heating or the discharge of a central heating buffer). The system can manage up to 24 heating circuits (24 C.MG3 modules). A WE-019/01 temperature sensor is included in the set.
