Thermal system solar controller DELTASOL® SLT

The DeltaSol® SLT effortlessly controls even complex systems and enables adaptation to the individual system requirements. Numerous pre-programmed optional functions such as thermal disinfection or zone loading can be combined and parameterised. It is also possible to directly choose from 27 pre-programmed basic systems. The operation via 2 main buttons and 1 adjustment dial, the Lightwheel®, follows the well-known operating concept. The manual mode and the holiday function can be activated by pressing a single button 4 relay outputs (incl. 1 potential-free extra-low voltage relay) 4 inputs for Pt1000 or Pt500 temperature sensors Input for 1 analogue Grundfos Direct Sensor™ 1 V40 impulse input (also usable as a Pt1000, Pt500 or KTY temperature sensor input) 2 PWM outputs for the speed control of high-efficiency pumps Numerous pre-programmed optional functions 27 basic system layouts to choose from Automatic function control according to VDI 2169 MicroSD card slot, LAN interface (optional), mini-USB port Data logging, easy transfer of controller adjustments prepared and firmware updates via SD card Max. number of collector fields:2 Max. number of stores:2 Weather-compensated heating circuits:- External heat exchanger:check Speed control of standard pumps:check Speed control of HE pumps:check ■ via integrated PWM output:check ■ via PSW adapter:check Hardware Temperature sensor inputs:4 (54) Sensor type:Pt1000, Pt500, KTY Inputs for Grundfos Direct Sensors™:analogue Input for CS10 irradiation sensor:- Impulse inputs for V40 flowmeter:1 Relay outputs in total:4 ■ semiconductor relays (speed control):3 (3)
