EC011309 - Room clock thermostat
Wireless Bluetooth connectivity enables seamless installation and integration with existing building management systems, reducing wiring complexity and installation time for retrofit projects. This feature translates to tangible cost savings and faster project ROI, especially in home renovations and small commercial spaces where wireless control is preferred. The 230V external power supply and 16A rating support robust switching for a single heater output, enabling reliable performance in typical heating circuits while minimizing energy waste and downtime in floor heating applications. The four operating modes—floor, room, combination, and power control—deliver precise temperature management, enabling energy-efficient operation of underfloor heating and zone control, with direct applicability in apartments, shops, and light-commercial settings. The resistance sensor provides accurate, responsive feedback for stable temperature control, reducing overshoot and improving occupant comfort. The compact 70 mm square footprint and 41 mm depth simplify wall installation in tight spaces, while the NO contact supports easy interfacing with standard actuators and controllers. IP21 protection ensures reliable indoor performance in kitchens, bathrooms, and humid environments where equipment is exposed to basic wash-down or splash risk. The Jussi design with Pure White appearance (RAL 9010) ensures a clean, inconspicuous integration into modern interiors, aligning with procurement aesthetics and branding. RoHS, REACH, and CE declarations streamline compliance for global projects, while the EPD and WEEE classifications support sustainability reporting in enterprise portfolios. ABBEcoHeat app compatibility unlocks remote programming and monitoring, reducing on-site visits and paperwork while enabling building operators to optimize schedules across multiple zones. The built-in week clock offers flexible scheduling, supporting energy-saving routines without sacrificing occupant comfort. This product’s comprehensive specification set reduces the need for supplementary controllers, lowering total-cost-of-ownership for system designers and facility managers.

FAQs
Begin by reviewing the Installation Instruction and TB16-23 manual PDFs provided with the product. Mount the unit on a suitable wall, connect the external 230V supply per local codes, and integrate the wireless link to the ABBEcoHeat app. Typically, the device supports floor, room, or combination modes, with a normally open (NO) contact to control a heater. Ensure IP21-rated placement away from direct water exposure and calibrate the sensor using the included setup instructions for accurate room temperature control.
Key specs include 230V supply at 50 Hz with 16 A maximum output, IP21 protection, a 5–35 °C measuring range, and a resistance sensor with a Normally Open contact for a single heater output. The device clock operates on a weekly cycle, it uses wireless connectivity, and has a standby power consumption of 0.5 W. The compact 70x70x41 mm housing weighs 0.106 kg and supports ABBEcoHeat app control.
Yes. The 2TKA00005259 supports floor heating mode in addition to room and combination modes, enabling precise zone control for underfloor systems. It is designed for wireless operation and is compatible with the ABBEcoHeat mobile app, allowing remote scheduling, monitoring, and tweaking of setpoints to optimize energy use across multiple zones without on-site visits.
The thermostat carries CE declarations and complies with RoHS and REACH requirements. It is also associated with WEEE categorization for end-of-life handling, and an EPD declaration supports environmental reporting. When sourcing for regulated projects, verify the CE documentation, RoHS status, REACH declarations, and applicable regional EPD information to meet company and project sustainability standards.
The device reduces energy consumption through precise on/off control, multiple operation modes, and remote scheduling via ABBEcoHeat, contributing to faster ROI in retrofit projects and ongoing energy savings in commercial spaces. With a standby consumption of 0.5 W and reliable IP21-rated performance, maintenance intervals are typically lengthened, as fewer field interventions are needed and firmware/app updates can be performed remotely.
