Multiplex solar control unit
Multiplex solar control unit for multi-tank and complex solar and heating systems, fitted with outputs and inputs for heat quantity meters (volume measuring instrument or VFS sensor required), web-connected (module required), actuation of high-efficiency pumps and MicroSD card slot. Pre-configured systems for up to 4 tank systems and possibility to control a weather-compensating heating circuit are available. Numerous functions such as drainback, booster, timer, bypass, external WT, twin pump, thermal disinfection, time-controlled thermostat function, zone charging and blocking protection can be connected, freely-programmable function blocks. Expandable by up to 2x multiplex EM (of which 21 are temperature inputs and 15 relay outputs), e.g. for additional weather-compensating heating circuit. Automatic function check as per VDI guideline 2169.
