For optimum adaptation to the solar heating system, two different control systems have been conceptualized. The DeltaSol® Plus / Flowmeter (Version A) version has got an integrated standard measurement of heat amount, based on a flow measurement.

Additional control functions can be accomplished by five accompanying temperature sensors. The version of DeltaSol® Plus / V 40 (Version B) forms an additonal variant for standard solar heating systems with increased measuring precision of the heat quantity measurement of heat amount.
