Wall-Hung Boiler Thermostat Buying Guide

This guide covers room thermostats for compatible wall-hung boilers. Start with the boiler's thermostat input and installation requirements, then choose a wired controller or a wireless room panel with a receiver. A WiFi feature or a familiar panel design does not establish compatibility with the boiler.

Check the boiler control input first

Send the boiler make, full model and a clear control-terminal diagram. For the AE-613 wireless wall-hung boiler thermostat, the proposed heating-demand output is a COM/NO dry contact. Confirm that the boiler accepts this on/off control route before ordering.

Do not assume a COM/NO relay is compatible with an OpenTherm or proprietary digital communication bus. If your boiler uses a digital interface, request a separate compatibility assessment with the exact model and terminal documentation.

Wired room thermostat or RF wireless kit?

• Wired installation: consider this route when suitable room-to-boiler control wiring is available. Confirm the selected thermostat's supply and output against the boiler documentation.
• RF wireless kit: the room panel communicates with a receiver, allowing more flexibility in panel placement. The receiver still needs its own power and the correct boiler-signal wiring.

For a retrofit, specify where the panel and receiver will be installed. Evaluate the radio link in the actual building before completing installation, rather than relying only on an advertised distance.

AE-613: wireless room panel and separate receiver

AE-613-BOILER-WIFI uses a 433 MHz RF link between the room panel and receiver. The panel can be wall mounted or placed on a desk and uses three AA alkaline batteries or USB-C external power. The receiver uses a separate AC 90–240 V, 50/60 Hz supply and connects to a compatible boiler through COM/NO.

The panel provides a color VA LCD, rotary temperature adjustment and weekly scheduling options. Tuya Smart or Smart Life app control is described in the product documentation; confirm the delivered kit and setup procedure. USB-C is a supply option, not a stated battery-charging function.

RF pairing and WiFi setup have different purposes

The RF link connects the room panel to its receiver. WiFi setup enables the supported app connection. These are separate commissioning tasks. Follow the supplied manual for the exact version, including the required panel state, and verify both the receiver response and app operation during sample testing.

The AE-613 specifications state an RF distance of up to 300 m, while the installation guidance recommends within 100 m. Walls, location and interference affect the usable range. Test at the planned installation positions before approving the project.

Keep receiver power and boiler signal wiring distinct

The receiver's AC supply and its dry-contact boiler connection serve different purposes. Have a qualified installer isolate power and check both the boiler instructions and the supplied receiver diagram before wiring. The boiler's thermostat input must not be treated as a mains-powered load.

Other load terminals illustrated in a manual do not establish suitability for every heating system. Send the intended application and wiring diagram for confirmation instead of assuming a wall-hung boiler kit can control any heater.

Sample acceptance before a bulk order

1. Confirm the boiler input, selected receiver and matched wiring documentation.
2. Check panel and receiver power, then test the RF link at the intended positions.
3. Verify heating demand from the local controls and the receiver response.
4. Check the requested app and any compatible voice service in the destination market.
5. Test weekly schedule transitions, temporary adjustments, child lock and the required behaviour after a power or network interruption.
6. Record the accepted configuration, quantity, manual language, packaging, logo and required market documentation.

Prepare a wall-hung boiler thermostat enquiry

Include the boiler model and terminal diagram, preferred room-panel location, receiver location, supply, app requirements, sample and project quantities, and destination country. Product configuration and price are confirmed through B2B quotation.

For branded supply, see OEM/ODM options and the sample and procurement policy. Request documentation for the exact product and target market; the certificate collection does not establish that every file applies to every model.
