Solar Controller - RESol DeltaSol BS/plus

Advanced solar zone controller with four input sensors and two external pump/switch relays

The RESOL DeltaSol BS Plus system controller is for standard solar thermal systems with 2 standard-relays allowing control of two zones such as water and AUX heating zone. It has an additional aqua stat function preprogrammed for different hydraulic layouts and is equipped with energy metering. The BS/Plus also comes standard with variable speed pump control.
