RESOL DeltaSol® SLL Solar 1-2 sensor controller

**The RESOL DeltaSol® SLL controller is the replacement controller for the Resol DeltaSol BS/4, BS/2, BS Plus, AX and AL controllers.**

The DeltaSol® SLL is the smallest controller of the SL series. It is optimised for small and medium-sized solar thermal and heating systems, with 2 pre-configured basic systems available. The DeltaSol® SLL offers automatic function control according to the VDI 2169 directive, and a V40 flowmeter input for heat quantity measurement.

Features:
  • Microbuttons for quick access to manual mode and the holiday function
  • 2 semiconductor relay outputs, both suitable for pump speed control
  • 4 inputs for Pt1000, Pt500 or KTY temperature sensors
  • 1 V40 impulse input for heat quantity measurement
  • 2 PWM outputs for speed control of high-efficiency pumps
  • 2 basic system layouts to choose from
  • Tube collector function, drainback option, and thermostat/backup heating function
  • Cooling functions including heat dump (System 1 only)
  • Automatic function control according to VDI 2169

Please read before ordering — Australian version

The DeltaSol® SLL supplied in Australia is a market-specific version, confirmed by RESOL. It does not include a thermal disinfection function, an SD card slot, or VBus RPT remote parameterisation. If your existing controller uses any of these, please contact us before ordering.

 The RESOL DeltaSol® SLL 1-2 controller comes with:
  • 1 x 20m roof sensor
  • 1 x 2.5m tank sensor
  • 1 x 5g thermal heat paste
  • Australian power supply (fitted)
  • Female pump lead (fitted)

Take a moment to browse our site. We stock a range of accessories to suit the RESOL DeltaSol® SLL controller. Accessories are easy to connect to the VBus on the controller. It is as easy as adding a sensor. The RESOL DeltaSol® SLL is used in the Apricus, Dux and Thermann solar hot water systems.

The RESOL DeltaSol® SLL controller has an IP rating of 20, which is fine for indoor use. If using outside, we recommend using a moisture-proof housing. We sell a version of this controller which includes a moisture-proof housing. Take a moment to browse our Pump Station section in Parts for more information.
