Solar station FlowCon C+ Evolution II with integrated controller

USE in closed loop design only. The circulation unit is used on the primary circuit of solar heating systems to control the temperature in the hot water storage. The pump inside the unit is activated by the signal from the differential temperature controller. In addition, this unit contains the functional and safety devices for optimum circuit control.

Features:

• All medium-bearing parts are made of brass.
• All connections ¾" female.
• With pre-assembled steel wall bracket.
• Full port ball valve in return pipe.
• Check valve inside the flow and return ball valve,
  manual opener, thanks to 45° position of the ball valve handle, 200mm WC each, special design for solar thermal systems, avoid any gravity circulation.
• Large ball valve handles easy grip and visible closing position.
• Airstop in the supply line
  for a permanent deaeration of the heat transfer medium.
• Function-optimized design insulation made of durable elastic EPP;
  100% insulation of the fittings – excellent pump ventilation and cooling.
• Solar controller integrated into the insulation, pre-wired and splash-proof.
• Solar safety assembly
  pressure relief valve 87 psi/6 bar, high-temperature pressure gauge 0-87 psi/0-6 bar, shut off valve, drain valve for flushing and filling, flat sealing connection for expansion tank.
• Full metal solar temperature gauges, 32-320°F/0-160 °C
  can be pulled off, with immersion sleeve integrated in the ball valve.
• Fully assembled with flat sealing union connections.
• With three speed solar circulation pump by Wilo
  without wire.
• Pump can be completely isolated, no draining necessary during servicing.
• Flowmeter
  Flow quantity measuring device with adjustable flow quantity gauge and function control device, installed in the (cold) return - up to 266 °F/130 °C heat resistant – two measurement ranges: 0.8-6 USgpm or 3-22 l/min.
• Flushing and filling unit integrated
  two drain valves (at the flow meter and at the safety assembly) permit filling and flushing the system.

The unit components enable:

• Medium circulation with specific pump
• Safety against pressure increase
• Accurate flow rate control
• Filling/draining the circuit
• Measuring the supply and return line temperature
• Separating the air contained in the circuit
• Shutting off the circuits and anti thermosyphoning
• Thermal insulation

The controller Type BS Plus is integrated in the insulation. It is designed for the application in various basic systems. This controller has 2 standard relay outputs and 4 sensor inputs for Pt1000 temperature sensors. The illuminated display with system monitoring (with blinking symbols for a clear allocation of the indicated data) permits a simple and clear appliance and function control. The controller is equipped with a storage temperature limit, an operation hours’ count, a thermostat function, a heat metering as well as (selectable) pipe collector functions. V-Bus. UL/CSA certified. Supplied with 4 Pt1000 sensors (Ø6 mm, 1 with silicon wire).
