Clear LCD & touch keys
Read the room temperature and adjust the setpoint directly on the tempered-glass front.
MATTER / AE-5503D
Connected room control for boiler systems. For compatible wall-mounted boiler heating systems, with the switching interface matched to the boiler.

Black finish shown. Four housing colors available.
CONNECTION & TERMINALS
Use the drawing for the exact version supplied. These are the original European-configuration connection images provided for this product.
The thermostat has its own AC supply. X1 / X2 are the boiler control contacts shown in the supplied drawing.

Confirm that the boiler accepts the specified dry-contact room-thermostat input. Do not assume the boiler control contacts are a mains supply output.
Isolate mains power. Wiring must be completed by a qualified installer using the supplied terminal labels and equipment instructions.
THERMOSTAT FEATURES
Read the room temperature and adjust the setpoint directly on the tempered-glass front.
The AE-5503D platform supports manual operation and weekly programming: four weekday periods and two off-day periods.
Power-off memory stores settings. Calibration and temperature limits help configure the thermostat for the installation.
Local functions are referenced to the AE-5503D platform manual. Confirm the supplied Matter firmware; local settings are not necessarily exposed in a Matter app.
APPLICATION SETTINGS
Use the internal room sensor for room-temperature control.
Configure upper and lower temperature limits for the intended application.
Match the switching interface to the boiler’s room-thermostat input.
SMART HOME SETUP
The current integration focuses on temperature and operating-mode control. Available modes and app layouts depend on the thermostat firmware and chosen platform.
Use the Matter setup code supplied with the thermostat and prepare the compatible controller required by your ecosystem.
Request the current ecosystem compatibility list and final sample specification. This page does not imply that all local functions are available in every Matter app.

INSTALLER REFERENCE

Switch off the supply and release the front panel as shown.
Follow the correct configuration drawing and secure the rear housing in the wall box.
Refit the front and lower clip. Restore power, configure the sensor and check heating operation before Matter pairing.
Check wall-box clearance and the mechanical drawing for the ordered version. The 60 mm figure is mounting-hole spacing, not the overall product size.
Send the boiler model and thermostat-terminal diagram when requesting a sample. The boiler control interface must be matched before wiring. OpenTherm, modulating control and universal boiler compatibility are not specified for this edition.
Please provide: boiler make/model, thermostat terminals, contact requirements and supply voltage, destination country, preferred ecosystem and quantity.
BUYER GUIDE
Use the diagram supplied for your ordered wall-mounted boiler heating configuration. Thermostats with the same front appearance can have different outputs and terminal assignments.
No. Black, white, silver and gold are housing choices. Within the same heating configuration, hardware and software are the same.
No. Temperature and operating mode are the current integration focus. Local schedules, calibration, sensor choices and advanced settings must be checked on the supplied firmware.
Select the correct electrical output before ordering. Electric heating loads, hydronic actuators and boiler dry-contact inputs need different configurations.
Send the heating-system type, supply voltage, load or actuator/boiler specification, sensor requirements, destination country, preferred Matter ecosystem, color and quantity.
