DELTASOL® MX
Multifunction controller

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 for FRH and FRHd humidity sensors
• Integrated control of up to 4 high-efficiency pumps via PWM outputs
• Data logging, storing, easy transfer of controller settings prepared and firmware updates via SD card
• Cooling over the heating circuit with condensation detection by means of a dew point switch or sensor
• Dew point calculation by means of the FRH(d) humidity sensor to avoid condensation
• Simplified setback timer, 0-10 V boiler control and DHW priority heating
• Remote access to the heating circuits with room control unit(s) or the VBus^®Touch HC App
• Extended optional functions, e.g. solid fuel boiler function with mixer and target temperature control
• Function blocks
• Heat pump demand (optional)
