Wall thermostat or smartphone app

Choose from WM-AU, WM-S-ECM, or CB-T-ECM wall thermostats, or use WiFi-enabled controls for smartphone access. Set your desired room temperature and the unit automatically heats or cools with continuously adjusting fan speed for silent operation.

Advanced integration options

Modbus/KNX integration for building automation, Bluetooth Low Energy (BLE) for direct app access, and centralised summer/winter switching when managing multiple units. The WiFi-ready design means occupants in hotels, short-term rentals, and shared residences can adjust temperature individually via smartphone.

Imperceptible noise levels

Tangential motor technology ensures noise remains imperceptible even during full-speed operation — a key differentiator in hospitality and wellness-focused projects where acoustic comfort is paramount.

Annual filter service

Inspect and clean or replace the polypropylene cellular fabric filter once a year. The EC motor and control board are sealed and require no lubrication — no specialist tools or engineer visit needed for routine upkeep.

Water circuit checks

Water connections are 1/2" BSP brass fittings with 10 bar maximum operating pressure. Check chilled water supply (7°C target) and hot water temperature (35–50°C) annually. Condensate drain should be inspected to ensure it's not blocked, particularly in humid climates.

5-year warranty

Carisma CRR-ECM comes with a 5-year warranty covering all mechanical and electrical components, subject to annual maintenance documentation. Extended warranty and professional maintenance packages are available.
