<strong>Rendamax</strong> will react to this and will open the regulator func tions (valves, etc.) in the system. Generally, the temperature of the water supply from the boiler(s) will need to be corrected to obtain the desired temperature in the connected circuits. Systems with a separate flow header and a return header Flow headers in combination with return headers are often used in renovation projects. Several circuits operate with mixing valves or diverting valves. In both cases a low velocity header or a bypass is necessary. Fig. 28 Boiler with vertically mounted low velocity header arranged with right hand connections Installations with multiple appliances For installations in which each appliance is fitted with a pump, the pump is switched off after the boiler has been shut down. Fig. 29 Installation with multiple appliances Hydraulic short-circuit In order to avoid a short circuit over a non-operating appliance, we advise the use of non-return valves. These may be either mechanically or electrically operated valves (see 5.4.2.4). Installations with multiple appliances without non-return valves The total resistance of the system (boiler, isolating valves and pipework) will be much greater than the resistance of the low velocity header. The baffles “X” (see fig. 30) prevent undesir able circulation through the non-operating boiler. Doc890/3456CV02B 43
<strong>Rendamax</strong> When two appliances are switched in cascade, it is advisable to employ this system. When appliances are controlled by a buil-ding optimising system using weather compensation or a compensating unit, the common flow temperature sensor must be mounted at the common flow pipe as indicated in the drawing.
