Danfoss RET B-RF


The Danfoss RET B-RF is a wireless room thermostat designed for use in residential and commercial heating systems. It allows you to control the temperature of a room or zone by wirelessly communicating with the boiler or heating system.

The RET B-RF consists of two components: the wireless thermostat and the receiver unit. The wireless thermostat can be installed in any room that you want to control the temperature of, and it communicates with the receiver unit that is wired to the boiler or heating system. The thermostat uses a digital display and buttons to allow you to set the desired temperature and adjust the programming schedule.

The RET B-RF also features a range of advanced functions, including adaptive start, which ensures that the room reaches the desired temperature at the programmed time, and holiday mode, which allows you to set a different temperature schedule when you’re away from home. The thermostat also has a frost protection feature, which prevents the temperature in the room from dropping below a certain level during cold weather.

One of the main benefits of the RET B-RF is its wireless functionality, which allows for easy installation and flexibility in terms of where you can place the thermostat. It also offers energy-saving features that can help you reduce your heating bills while maintaining a comfortable temperature in your home or commercial building.
