The Schneider Electric MTN6212 is a System M flush-mounted KNX room station: push-button 2-gang plus with integrated room temperature control unit (RTCU), white backlit display, and four parameterisable keys. One device covers lighting, blinds, scenes, and HVAC setpoints — reducing wall clutter in residential and commercial rooms.

Choose a finish at checkout — all three stocked variants share the same KNX application and RTC logic:

• MTN6212-0319: Polar White, Glossy
• MTN6212-0325: Active White, Glossy
• MTN6212-0414: Anthracite

Key Features — Room Control and RTCU

Push-buttons and Display

• Four keys: Configured as dual-surface pairs or single push-buttons — switching, dimming, blinds (absolute/relative), scenes, 8-bit regulators, fan control, notifications.
• Display: White backlit LCD for time, date, temperature, operating mode; brightness adjustable; can act as orientation light.
• Status: Five red LEDs; menu-driven operation.
• Bus: Integrated KNX bus coupler; connection via bus connecting terminal (no separate room bus device).

Room Temperature Control

• Controller types: 2-step, continuous PI, switching PI (PWM); output 0–100 % or ON/OFF.
• Modes: Comfort, comfort extension, standby, night reduction, frost/heat protection.
• HVAC pairing: Drives KNX valve actuators or switch/heating actuators — coordinate with MTN645094 fan coil, MTN6700-0104 hybrid channels, or MTN6700-0304 for high-current valve circuits.
• Presence: Combine with MTN6303-0019 or MTN6300-0019 for occupancy-based setback.

Choosing MTN6212 vs MTN6214 and Touch Panels

Use MTN6212 when four keys plus RTCU and display are enough. Choose MTN6214 for eight keys and IR; choose MTN6215-0410S for KNX Secure visualization. Match the frame finish to other System M mechanisms on the same plate.
