This document serves as the operation manual for the Daikin Altherma 3 R MT ECH₂O system, providing users with essential information for its safe and efficient use. It is part of a comprehensive documentation set that includes general safety precautions, a user reference guide, installation manuals for both outdoor and indoor units, an installer reference guide, and an addendum book for optional equipment. The manual emphasizes the importance of reading all documentation carefully before operating the user interface to ensure optimal performance and encourages users to consult their installer for system configuration details.
The Daikin Altherma 3 R MT ECH₂O system is designed to provide space heating and cooling (for reversible models), as well as domestic hot water production. Depending on the system layout, it can heat or cool a main zone (e.g., living room) and additional zones (e.g., bedroom), and produce domestic hot water stored in an energy storage tank. The system utilizes a heat pump, with an outdoor unit and an indoor unit, and can connect to various heat emitters such as underfloor heating, radiators, heat pump convectors, or fan coil units. A dedicated Human Comfort Interface (BRC1HHDA) or an external room thermostat can be used to control room temperature.
The system features a user interface with an LCD screen, dials, and buttons for navigation and setting adjustments. A status indicator with LEDs shows the unit's operating mode (standby, operation, or malfunction). The ON/OFF operation for space heating/cooling and tank heating can be controlled via the user interface. The system also supports weather-dependent operation, where the desired leaving water or tank temperature is automatically adjusted based on the outdoor ambient temperature, aiming to optimize energy consumption.
For domestic hot water, the system offers a "Reheat mode" where the storage tank continuously heats to a set temperature when it drops below a certain value. A "Scheduled reheat mode" allows the tank temperature to vary according to a programmed schedule. Additionally, a "Powerful operation" mode can be activated to quickly heat domestic hot water using a backup or booster heater, useful during periods of high demand.
The user interface allows for various adjustments and monitoring:
