The EM extension module can be connected to the DeltaSol MX, DeltaSol BX Plus or to the HC heating controller and provides 5 additional relay outputs and 6 additional sensor inputs. The EM can be used for all optional functions of the above mentioned controllers and can also control a heating circuit. With 5 extension modules and its 2 internal heating circuits, for example, the DeltaSol MX can manage no less than 7 heating circuits complete with individual room thermostats.
