DeltaSol® SLT System Controller is a free programmable solar thermal controller, coming with 27 pre-programed but freely selectable Solar Thermal system layouts. Among the 27 layouts, the user can select the No. of collector arrays, No. of Solar storage tanks, and hydraulic variants ( valve or pump logic). Solar Thermal functions are picked as add-ons. Hardware consists 5 PT1000 sensor inputs, 1 input for impulse flow meter, 1 input for Grundfos sensor, 2 PWM/0-10V variable speed outputs for ECM pumps, 3 semiconductor relays, 1 dry contact relay and 1 VBus terminal for RESOL Vbus data transfer/storage device. SD card slot for local data logging and programming transfer. The central LED button indicates different operation statuses: normal operation, fault, holiday mode or manual operation mode.
