Radiator Thermostat eQ-3 Homematic IP HKT 5er Set — smart radiator valve set, 5 units

The eQ-3 Homematic IP HKT 5er Set is a set of five smart radiator thermostats designed to replace standard radiator valves and enable precise, programmable temperature control in individual rooms. Each unit integrates with the Homematic IP ecosystem to provide remote adjustments, scheduled temperature profiles and automated heating management through the Homematic IP app and compatible central controllers. The set is intended for retrofitting homes or small apartments where accurate room-by-room regulation and energy-efficient operation are required.

Advantages

Each radiator thermostat in the set offers individual temperature control for separate radiators, allowing flexible zoning and tailored comfort. The devices support scheduling and remote control via the Homematic IP platform, which enables automated heating patterns and on-demand adjustments from a smartphone or central unit. Installation is designed to be straightforward on common valve types, and the compact design minimizes visual impact while providing clear temperature feedback. Integrated energy-saving features help reduce unnecessary heating and support efficient use of heating systems.

Suitable for

• Upgrading radiators in homes and small apartments for smart heating control
• Creating independent heating zones in living rooms, bedrooms and home offices
• Implementing scheduled temperature profiles for day/night or away modes
• Remote temperature adjustment and monitoring via Homematic IP app or controller
• Improving energy efficiency and reducing heating costs by precise regulation

Key specifications

• Pack quantity: five individual radiator thermostat units
• Communication: compatible with the Homematic IP wireless system for remote control and scheduling
• Control: individual temperature setpoint control per valve with programmable schedules
• Compatibility: supports common radiator valve connections (adapter options may be required for specific valve types)

How to use

Install each thermostat on the radiator valve following the manufacturer’s installation instructions and, if necessary, fit the appropriate mechanical adapter for the existing valve. Pair each unit with the Homematic IP central device or app to enable remote control, scheduling and integration with other Homematic IP devices. Configure desired temperature setpoints and weekly schedules using the app or controller interface. Manual adjustments can be made directly on the unit if needed. Replace batteries as indicated by the low-battery warnings to maintain uninterrupted operation.

Recommendations

For optimal energy savings and comfort, configure room-specific schedules that lower setpoints during absence or night hours and raise them before occupancy. Ensure proper fit on the radiator valve and verify the thermostat’s response by testing a few manual changes after installation. Use the Homematic IP app to monitor battery status and to integrate the thermostats with window sensors or presence detection for automated setback when windows are opened or rooms are unoccupied.
