Which RTL Control Box Is Right for My Project?
Two control boxes are available for the heating kits to control the temperature and for connection to the existing heating system. In both cases, the heating water temperature is controlled via a return temperature limiter [RTL]. The table provides a direct comparison of the respective range of functions.

* For integration into Smarthome systems, the thermostat head of the Multibox 4K-RTL can be exchanged and replaced with a wireless radiator thermostat. The Smarthome thermostat head must fit a 30 × 1.5 mm connection thread or have an appropriate adapter. Integration into a Smarthome system offers additional control convenience, especially when operating several heating sets.
