Wall-mounted heating controller DELTASOL® MX

for solar water heaters

The DeltaSol® MX is the most versatile system controller for complex solar and heating systems in our product range. It is ideal to control a combination of solar and non-solar parts of the system. Easy combination and parameterisation of pre-programmed functions for several millions of hydraulic variants. 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™ Integrated control of up to 4 high-efficiency pumps via PWM outputs Data logging, storing, easy transfer of controller adjustments prepared and firmware updates via SD card Cooling over the heating circuit with condensation detection by means of a dew point switch Simplified timer, 0-10 V boiler control and DHW preheating 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 Max. number of collector fields:31 Max. number of stores:51 Weather-compensated heating circuits:2 (72) 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:12 (154) Sensor type:Pt1000, Pt500, KTY Inputs for Grundfos Direct Sensors™:analogue, digital Input for CS10 irradiation sensor:check Impulse inputs for V40 flowmeter:3 Relay outputs in total:14 ■ semiconductor relays (speed control):13 (13) ■ electromechanical relay:- ■ potential-free relay with changeover contact:1
