The SOREL TDC SMART COMPACT is the compact solution in the new SOREL TDC SMART controller series - identical in size to the Basic controller. At the same time, it is equipped with an additional temperature sensor and 230V output, allowing it to be used to control more complex systems.

In solar collector systems, it will ensure economical and gradual heating of the boiler or storage tank by controlling the solar pump according to the temperature difference between the solar collector and the hot water tank. Unlike the Basic controller, the Compact controller will also be able to control an alternative heat source in parallel, a system with two separate heat exchangers or a system with two separate solar collector systems, for example.

SOREL TDC SMART controllers are equipped with a colour touchscreen display and, unlike older SOREL controllers, a WiFi module for remote control is included as standard.
