RESOL BX Plus Controller

Solar Controller

Apricus cooperate with RESOL solar controllers for residential & commercial solar hot water systems. The RESOL controllers for standard solar thermal systems. The DeltaSol® BX Plus is a system controller for multi-store solar and heating systems. The intuitive commissioning menu leads you through the system configuration by requiring the most important adjustments directly after connecting the controller. For an optimum overview, all sensor and relay allocations are listed in the service menu.


Key Features     

  • 8 sensor inputs and 5 relay outputs

  • Data logging, storing, easy transfer of controller adjustments prepared and firmware updates via SD card

  • Pre-programmed optional functions such as drainback option, time-controlled thermostat function, thermal disinfection

  • Up to 2 extension modules via RESOL VBus® connectable (21 sensors and 15 relays in total)

  • 2 PWM outputs for speed control of high-efficiency pumps

  • Automatic function control according to VDI 2169: Flow rate and pressure monitoring, warnings for too high ΔT values, interchanged flow and return pipes and night circulation

  • Modulating heating control with 0-10 V boiler control (with EM Extension Module)
