The RESOL Delta Sol® MX is a system controller offering almost endless possibilities in planning and controlling solar thermal systems, hydronic heating/cooling systems. It is equipped with 14 relay outputs and 4 PWM outputs for the speed control of ECM pumps. Additionally, the controller has three impulse inputs as well as a range of different sensor inputs. up to 5 EM Extension modules can be connected via the RESOL vBus®. The integrated SD memory card slot enables an easy datalogging to an SD memory card and a quick, effortless transfer of logged data to a PC.

 The DeltaSol® MX controller is now c LCus certified and meets the demands of the UL 60730-1:2009 and CSA B60730.1:2002 standards.

Features: 

  • 14 relay outputs and 12 inputs for Pt1000, Pt500 or KTY temperature sensors

  • Up to 5 extension modules via RESOL VBus® (45 sensors and 39 relays in total)

  • Inputs for analogue and digital Grundfos Direct Sensors™ as well as 1 FlowRotor

  • Speed control of standard and high-efficiency pumps

  • Data logging, storing and firmware updates via SD memory card 

  • Hydronic Heating Circuits ( talking to Dry-Contact regular room thermostat) up to 10 zones with outdoor temperature reset, Hydronic Cooling over the heating circuit with condensation detection by means of a dew point switch, DHW pirority control 

  • Simplified timer, 0-10 V boiler control and DHW preheating

  • Basic solar systems also for 3 collector fields
