Resol DeltaSol MX controller has maximum 15 sensor inputs, 13 relay outputs and 1 dry contact relay. Beside its brilliant capability of controlling complex solar thermal systems, it is also an optimal solution to control multi-zone hydronic systems.
All these typical functions are available:
The built in heating curve is necessary for hydronic system “adjusts” supply temperature with considering outdoor temperature ( outdoor temperature reset);
Floating Point control logic for 3-way mixing valve combining with heating curve;
Talking to regular dry-contact room thermostats, executing call for heat and activating zone valves/zone pumps; a MX controller talks to up to 10 regular dry-contact room thermostats simultaneously;
Calling Boiler Demand based on Target temperature or configured supply temperature by heating curve;
Domestic Hot Water ( DHW) Priority Control and/or DHW calls boiler demand;
The Heating controller HC has 9 pre-programmed control circuits providing flexible options of house heating system control. The controller packages single/multiple-zone space heating, DHW heating, boiler protection, heating priority, temperature mixing and weather-compensated room temperature control logics. Besides, it is compatible with Resol solar cell Cs10, Resol V40 flowmeter, modulating pumps/valves with 0-10VDC, Resol digital flow and pressure sensors and 5 Resol Extension Modules; these associated devices assist users to execute energy metering, creating interlock logics by function blocks, and monitoring solar irridiation in solar-based systems. The heating controller is able to work with any of Vbus devices issued by RESOL.
