RESOL DeltaSol® SLL Solar 1-2 controller

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.
