Resol FloCal B Solar Twin Line Pump station c/w BS3 controller

The FloCal B combined pump station and controller harvest the solar energy captured by the collector and deliver the heat to be stored to the solar hot water storage cylinder.

The pump is controlled by constant measuring of heat values at 3 locations:

• the collector
• the lower heat exchange coil in the cylinder
• the upper heat exchange coil in the cylinder

Provision is made on the controller for supplementing an additional heat source e.g a boiler, on relay 2 to provide back up
