The EM extension module can be connected to the DeltaSol® MX, DeltaSol® BX Plus or to the DeltaTherm® HC 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.
The Extension Modules themselves do not require any adjustments, they are simply connected and assigned to the controller. The inputs and outputs of the registered modules will then be available for all functions of the controller.
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.
