Wall-mounted heating controller DELTASOL® E

for solar water heaters

A multitude of adjustable functions and options are possible using 7 relay outputs and 10 sensor inputs for Pt1000, CS10 and V40. Due to its intelligent and easy-to-understand system configuration and its integrated calorimeter, the controller also offers the control of complex systems with up to 4 weather-compensated heating circuits. For data communication and remote maintenance, the controller is equipped with the RESOL VBus®, which permits two-way communication between modules, PCs or dataloggers. 7 basic systems to choose from 10 sensor inputs 7 relay outputs Pump speed control, solar operating hours counter and heat quantity measurement Internal calorimeter 4 heating circuits can be activated Function control RESOL VBus® User-friendly operation Energy-efficient switching-mode power supply Max. number of collector fields:2 Max. number of stores:4 Weather-compensated heating circuits:1 (43) 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:10 Sensor type:Pt1000 Inputs for Grundfos Direct Sensors™:- Input for CS10 irradiation sensor:check Impulse inputs for V40 flowmeter:1 Relay outputs in total:7 ■ semiconductor relays (speed control):6 (3) electromechanical relay:- ■ potential-free relay with changeover contact:1 ■ potential-free relay with normally open contact:- ■ potential-free high-current relay:- PWM outputs:3 ■ convertible to 0-10 V:3 Real-time clock:check Data interface:VBus®
