Panasonic and tado° Expand Aquarea Heat Pump Control System

Panasonic Heating & Cooling Solutions and tado° have expanded their joint control system for Aquarea heat pumps. The update includes a room-by-room heating demand aggregation function, AI analytics within the AI Assist subscription, and optimization based on dynamic tariffs. The article was published on 03.11.2026 in issue 11-2026.

Aquarea Sync Mechanism

The Aquarea Sync function sums the heating demand from all tado° thermostats and dynamically adjusts the supply temperature. When demand is low, the heat pump optimizer X reduces the supply temperature by up to 5 °C. If individual rooms require more heat, the supply temperature is increased by up to 2 °C, while the smart radiator thermostats X in the remaining rooms close their valves. According to the manufacturer, total savings can reach up to approximately 10%, depending on the building, system configuration, and operating conditions. When heating demand is virtually absent, the heat pump enters standby mode after 30 minutes, reducing compressor runtime.

AI Assist Subscription

Within the AI Assist subscription, AI-based functions analyze operational data and temperature trends:

• Adaptive Heating studies heating and cooling patterns of individual rooms and reduces temperature overshoots;
• an open-window detector stops heating when a rapid temperature drop is detected;
• Care & Protect notifies via the app if a room remains cold while heating is running, sometimes indicating a probable cause.

Additionally available: geolocation-based control, pre-heating before arrival, and holiday mode.

Tariff Optimization and PV Integration

The Balance for Heat Pumps function in the app shifts operation to hours with lower electricity prices under dynamic tariffs, taking into account electricity price, forecast outdoor temperatures, building thermal characteristics, and, where available, the forecast output of a photovoltaic installation. Alternatively, tariffs can be manually set by time of use or as a fixed rate. Photovoltaic installations connect via Solar Manager or Kiwigrid.

Hardware and Connectivity

The heat pump optimizer X connects to the Aquarea main board via the CN-CNT connector and communicates with all tado° room devices over a wireless channel. The lineup also includes the wired smart thermostat X, smart radiator thermostat X, wireless temperature sensor X, and radio receiver X for zone valves.
