Wall-mounted heating controller DELTASOL® BX PLUS

for solar water heaters

The DeltaSol® BX Plus is a system controller for multi-store solar and heating systems. The intuitive commissioning menu leads you through the system configuration by requiring the most important adjustments directly after connecting the controller. For an optimum overview, all sensor and relay allocations are listed in the service menu. 8 sensor inputs and 5 relay outputs Data logging, storing, easy transfer of controller adjustments prepared and firmware updates via SD card Pre-programmed optional functions such as drainback option, time-controlled thermostat function, thermal disinfection Up to 2 extension modules via RESOL VBus® connectable (21 sensors and 15 relays in total) 2 PWM outputs for speed control of high-efficiency pumps Automatic function control according to VDI 2169: Flow rate and pressure monitoring, warnings for too high ΔT values, interchanged flow and return pipes and night circulation Modulating heating control with 0-10 V boiler control (with EM Extension Module) Max. number of collector fields:21 Max. number of stores:41 Weather-compensated heating circuits:(22) 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:8 (94) Sensor type:Pt1000, Pt500, KTY Inputs for Grundfos Direct Sensors™:digital Input for CS10 irradiation sensor:check Impulse inputs for V40 flowmeter:1 Relay outputs in total:5 ■ semiconductor relays (speed control):4 (4) ■ electromechanical relay:- ■ potential-free relay with changeover contact:- ■ potential-free relay with normally open contact:1 ■ potential-free high-current relay:-
