Danfoss Link™ FT/FT-S wireless relay units

Your wireless system includes one or more wireless relays. The wireless relay is mostly used in one of the following ways:

  1. As part of a room heating solution based on an electric heat source (electric floor heating or an electric radiator). In this case, the system also has a Danfoss Link™ RS installed, which controls the room temperature via the heat source/relay.
  2. In installations with electric floor heating, there is also a built-in floor sensor (the sensor is embedded in the concrete).Danfoss-FT-S-Wireless-Relay-Units-fig-1

Does my system have a built-in floor sensor?

You can easily see if your system is controlled by room or oor temperature by accessing the room in question on the Danfoss Link™ panel. Simply select Heat control in the House control menu. If the room is controlled by an ordinary room sensor, a thermometer will appear in the display. If, on the other hand, the room is tted with a oor sensor, a thermometer will be shown in the oor of a house. If the relay is used with an electric radiator along with a Danfoss Link™ RS … it is important that the radiator’s own thermostat is set to the highest possible setting (which takes the thermostat out of play). Please note! The wireless relay also functions as a repeater.

unit (signal amplier) and helps to secure a strong wireless network. The relay must therefore always be on.Danfoss-FT-S-Wireless-Relay-Units-fig-2 Danfoss-FT-S-Wireless-Relay-Units-fig-3

Product Specifications

  • Product: Danfoss LinkTM FT/FT-S wireless relay units

Product Usage Instructions

Checking for Built-in Floor Sensor
To determine if your system has a built-in floor sensor:

  1. Access the room in question on the Danfoss LinkTM panel.
  2. Select Heat control in the House control menu.
  3. If a thermometer appears in the display, it indicates an ordinary room sensor. If a thermometer is shown on the floor of a house, it means there is a floor sensor.

Usage with Electric Radiator
If the relay is used with an electric radiator along with a Danfoss LinkTM RS:

  • Ensure the radiator’s own thermostat is set to the highest possible setting to override its control.

Ensuring Proper Functionality
For optimal performance:

  • The wireless relay must always be powered on to function as a repeater unit and maintain a strong wireless network.

Frequently Asked Questions

Does my system have a built-in floor sensor?
You can check for a built-in floor sensor by accessing the room on the Danfoss LinkTM panel and observing the displayed thermometer location.

What should I do if using the relay with an electric radiator?
If using the relay with an electric radiator, ensure the radiator’s thermostat is set to the highest temperature for proper functionality.
