Via per Alzo 39, 28017 San Maurizio d’Opaglio (NO) Italia  consulenza.prodotti@giacomini.com  +39 0322 923372 - giacomini.com The R586S preassembled units have been designed to guarantee utmost operational reliability, dimension compactness and, last but not least, simplified installation and service of solar thermal systems. The circulation unit includes:

• ErP-complying circulator, specific for solar applications, controlling the thermo-conductor fluid flow based on the settings of the regulation unit. The ball valves installed on the bottom and top enable to maintain the system without emptying the circuit.
• Mechanical flow meter to directly calculate the thermal energy provided by the solar panels.
• Filling group including filling and drain cocks and regulation valve.
• Safety group with 6 bar calibrated safety valve, complying with the PED (2014/68/UE - Cat. IV) rule, pressure gauge and outlet for connection to expansion tank.
• Deaerator group with manual discharge valve.
• Ball valves with integrated check valve and each equipped with a thermometer to read solar circuit delivery temperatures.
• PPE insulation cover to ensure an efficient thermal insulation. It includes two removable spacers to install the regulation unit on the group side and carry out adjustment, filling and draining of the system. The cover also enables to view the thermometers mounted on the delivery and return manifolds, the pressure gauge mounted on the safety group, air circulation for cooling of the integrated circulator and, by means of a steel plate on the back, installation on boilers or walls. To be ordered separately:
• Electronic regulation unit with Pt1000 temperature probes. R586S Datasheet 0237EN  12/2022 2-way circulation unit, for solar thermal systems

The pump reduces the delivery head to half in the case of decreasing volume flow in the pipe network. Electrical energy saving by adjusting the delivery head to the volume flow requirement and lower flow rates. There are three pre-defined pump curves (I, II, III) to choose from. ∆p-v (variabile) Q [m3/h] Q [m3/h] P1 [W] H [m] H [kPa] III II I ∆p-v max. max.

• Press the operating button briefly (approx. 1 second).  LEDs display the set control mode and pump curve. Air venting
• Fill and vent the system correctly. If the pump does not vent automatically:
• Activate the pump venting function via the operating button: press and hold for 3 seconds, then release.  The pump venting function is initiated and lasts 10 minutes.  The top and bottom LED rows flash in turn at 1 second intervals.
• To cancel, press and hold the operating button for 3 seconds. After venting, the LED display shows the previously set values of the pump.

The V valve adjusts the flow starting from the “completely open” position (screwdriver tip in vertical position) and turning clockwise. When the V valve is completely closed (screwdriver tip in horizontal position), the A and B cocks can be used to fill and drain the system. V A B The ball valves integrated in the circulation unit for sectioning of the solar panels are both equipped with a check valve to prevent undesired circulations. Should specific operational conditions (e.g. when filling the system) require circulation of a thermo-convector fluid also in the opposite direction, the check valves can be opened using the A wrench to move the rods. A Manual air vent valve mounted on delivery manifold. It must be moved using the special R74Y001 wrench. For proper operation, a dearetor filter F has also been installed inside the support insert and can be easily removed for replacement or ordinary maintenance operations. R74Y001 F
