New and improved Roth Touchline® SL

Now with game-changing features and a brand new design

The Roth Touchline® SL system for underfloor heating, cooling and radiator control. The system is suitable for individual temperature control in all types of buildings with underfloor heating.

The system can be controlled via the Roth Touchline app if the system is extended with the Roth Touchline® SL WiFi module. The system is quick to set up and super easy to operate.

The system can consist of 1 Roth Touchline SL Master control unit with 8 channels, which can be wirelessly connected with up to 3 Roth Touchline®® SL expansion modules (8 channels each). Each 8-channel control unit/expansion module can also be connected to the 4-channel expansion module via a BUS cable. In total, there are a total of 48 zones, with the possibility of connecting 192 Roth Touchline® actuators 230V.

New upgraded Roth Touchline® SL - just as you know it, only better

  1. A room thermostat can now also control multiple outputs. For example, if you have 6 underfloor heating circuits in one room, simply report the room thermostat to the 6 circuits.
  2. Now we also have a 12 channel control unit (8+4)
  3. Now we have both a 4 channel and 8 channel expansion control unit, so it is easier to adapt to the current system.
  4. Bypass function - some heat pumps may need this.
  5. All control units come standard with a DIN rail for easy installation.
  6. Via the Roth Touchline® app, your customers get wireless control, monitoring and alarm notifications.

If you use the Roth Touchline® SL module, you get a weather-compensated control so that your underfloor heating system always has the correct flow temperature. In addition, the control unit has a 230V output to the pump, as well as a voltage-free switch to control an additional heating or cooling unit. In addition to developing and improving our Master, expansion module and WiFi module, we are also expanding the range with a 4-channel expansion module. The 4-channel expansion module allows you to create an extremely affordable 12-channel system.

Each control unit/expansion module (8 channels) can be connected to the 4-channel expansion module via a BUS cable. To make it easy, we have also combined our Master control unit with 8 channels and our new expansion module with 4 channels in one package. This makes it even simpler to install a complete 12-channel system.

Note: Old controllers and WiFi modules are not compatible with the new controllers. You can quickly see if it is our new or outgoing control units: Our new control units are with light grey display and on the outgoing ones, the display is dark grey.

Disclaimer

We have recently learned that data traffic on the LTE800 bandwidth (e.g., 5G in mountains and/or in long-distance areas) may cause issues related to blocking of radio signals sent internally between Roth’s wireless products if the masts are too close or if the signal strength is too high.
Further, we cannot completely exclude the possibility that the installation or implementation of radio-based technologies in the future may cause similar issues.

All of the aforementioned issues are in all cases caused by conditions beyond Roth’s control. Roth can thus not be held liable for, or acknowledge claims attributable to, any such interruptions caused by installations (etc.) carried out by third parties beyond Roth’s control.
