Regulador de calefacción por suelo radiante 8 canales motorizado, eQ-3 Homematic IP, termostato digital (RF, AC 230 V)

The eQ-3 Homematic IP Floor Heating Controller is an 8-channel motorised digital thermostat for zoned underfloor heating. It controls up to eight motorised actuators via RF communication and monitors room temperatures via compatible wall thermostats. Power is via AC 230 V with a nominal consumption of 500 mA. The device supports stepless control of each heating circuit, automatic hydraulic balancing, and configurable heating and cooling profiles to maintain precise indoor climate control.

Advantages

The controller provides precise, infinitely variable control of individual heating circuits for uniform temperature distribution and quieter, more efficient operation than simple on/off control. Automatic hydraulic balancing dynamically adapts water flow for each circuit during operation, improving system efficiency without manual adjustments. Installation is flexible and fast: the unit can be mounted on a DIN rail or directly on the wall and uses screwless plug-in and clamp connections for tool-free wiring. The controller supports up to six profiles and multiple daily temperature changes and can be paired directly with wall thermostats without an access point for basic operation.

Suitable for

• Zoned underfloor heating systems with up to eight motorised actuators
• Residential new builds and retrofits requiring individual room temperature control
• Smart home setups using RF-connected thermostats and actuators
• Applications needing both heating and cooling control

When it may not be suitable

This controller is designed for use with motorised actuator-based underfloor heating circuits and requires AC 230 V supply. It is not intended for direct control of high-voltage heating elements or systems that do not use compatible actuators and RF thermostats. For installations that require integration with specific third-party wired bus systems or non-RF devices, additional interface components or different controllers may be necessary.

Key specifications

• Channels: 8 independent motorised heating circuit outputs
• Control type: Stepless (infinitely variable) output per circuit
• Communication: RF interface for thermostats and actuators
• Display: LCD for status information
• Power: AC 230 V supply, nominal consumption 500 mA
• Profiles: Up to 6 programmable heating/cooling profiles with multiple daily setpoint changes
• Mounting: DIN rail or wall mount
• Features: Automatic hydraulic balancing during operation
• Color: White

How to use

Mount the controller on a DIN rail or fix it to the wall and connect the supply and actuator wiring using the provided screwless plug-in and clamp connections. Pair the device with Homematic IP wall thermostats or compatible RF thermostats via the RF pairing procedure; for basic operation you can pair directly with wall thermostats without an access point. Configure heating and cooling profiles and setpoints via the Homematic IP app or via compatible wall thermostats, then monitor and adjust room temperatures as required. The controller will continuously adapt actuator outputs and perform hydraulic balancing automatically during operation.

What to consider before purchase

• Requires AC 230 V power supply and compatible motorised actuators
• Intended for RF-based thermostats and actuators; verify compatibility with existing devices
• Designed for zoned underfloor heating systems—check the number of circuits needed (up to 8)
• May require an access point only for extended smart-home cloud features; direct pairing with wall thermostats works without Internet

Recommendations

The controller performs best in systems with matching Homematic IP actuators and wall thermostats; use the Homematic IP app for full profile configuration and remote monitoring, and allow the automatic hydraulic balancing to run continuously for optimal efficiency.
