Kit composed of Honeywell T87 digital thermostat + BDR91 receiver

The Honeywell T87 digital thermostat kit along with the BDR91 receiver, reference Y87RF2058, is a complete and modern solution for controlling heating systems wirelessly and efficiently. This system is designed for boiler control applications and multi-zone systems, providing intuitive management, both locally and remotely, when combined with the RFG100 Internet gateway and the Honeywell TCC App.

The T87 thermostat features a sleek and modern design that easily integrates into any decor. Its large backlit display and rotary dial make operation simple and intuitive. The 0.5°C accuracy ensures precise temperature control, optimizing comfort at home and preventing unwanted temperature fluctuations.

Connectivity and remote control

This kit has the capability to connect to Honeywell's RFG100 gateway, allowing users to manage heating remotely through the TCC App on smartphones and tablets. This feature offers greater flexibility, as users can adjust the temperature or schedule heating from anywhere, ensuring that the home always has the perfect temperature regardless of the user's location.

Compatibility with OpenTherm and Evohome systems

The Honeywell T87 thermostat is compatible with OpenTherm systems, allowing for modulating communication between the thermostat and the boiler for more efficient heating control. Additionally, the thermostat can be used as a room unit in multi-zone systems such as Evohome or in underfloor heating systems that use the HCE80 controller.

Simple and practical control

The rotary dial of the thermostat facilitates quick temperature adjustments, while its large backlit display allows for clear visibility of the ambient or set temperature, even in low light conditions. Furthermore, the thermostat allows for setting maximum and minimum temperature limits, adding a layer of safety to prevent overheating or excessively low temperatures in the home.

The thermostat operates on 2 AA alkaline batteries, which provide a minimum lifespan of 2 years, with a low battery indicator to alert the user when replacement is necessary.
