Thermal system solar controller DELTASOL® BX SERIES

The DeltaSol® BX is equipped with 26 pre-programmed basic systems for a broad range of 1- and 2-store systems. Pre-defined functions facilitate system parameterisation. The DeltaSol® BX L has been especially developed as an economical solution for multi-store solar thermal systems. It features pre-programmed system layouts for a range of 2- and 3-store systems and special functions such as an extended priority and loading logic. With the integrated SD card slot, system data can easily be logged and transferred to a computer. 4 relay outputs and 5 Pt1000 temperature sensor inputs 2 inputs for analogue Grundfos Direct SensorsTM (DeltaSol® BX) 2 PWM outputs for the speed control of high-efficiency pumps 26 basic systems to choose from (DeltaSol® BX), 9 basic systems (DeltaSol® BX L) For 2- and 3-store systems (DeltaSol® BX L) Drainback option (DeltaSol® BX) Thermal disinfection function, heat dump function Unit °C and °F selectable Max. number of collector fields:2 Max. number of stores:2 [DeltaSol® BX], 3 [DeltaSol® BXL] Weather-compensated heating circuits:- External heat exchanger:- Speed control of standard pumps:check Speed control of HE pumps:check ■ via integrated PWM output:ja [DeltaSol® BX] ■ via PSW adapter:ja [DeltaSol® BX L] Hardware Temperature sensor inputs:5 Sensor type:Pt1000 Inputs for Grundfos Direct Sensors™:analogue [DeltaSol® BX] Input for CS10 irradiation sensor:- Impulse inputs for V40 flowmeter:1 Relay outputs in total:4 ■ semiconductor relays (speed control):3 (3) ■ electromechanical relay:1 ■ potential-free relay with changeover contact:- ■ potential-free relay with normally open contact:- ■ potential-free high-current relay:-
