RESOL DeltaSol® SLL Solar 1-3 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. Its equipment is optimised for small and medium-sized solar thermal and heating systems, 10 pre-configured basic systems are available. The DeltaSol® SLL is also the first controller of its category to offer the automatic function control according to the VDI 2169 directive. Additionally, it is equipped with a potential-free extra-low voltage relay for backup heating demand and a V40 flowmeter input for heat quantity measurement.

Features:
  • Microbuttons for quick access to the manual mode and the holiday function
  • 3 relay outputs (incl. 1 potential-free extra-low voltage relay)
  • 4 inputs for Pt1000, Pt500 or KTY temperature sensors
  • 1 V40 impulse input
  • 2 PWM outputs for the speed control of high-efficiency pumps
  • 10 basic system layouts to choose from
  • Automatic function control according to VDI 2169
  • Heat pump demand (optional)
 The RESOL DeltaSol® SLL 1-2 controller comes with:
  • 1 x 20m roof sensor
  • 2 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® BS/4 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.
