Page 8: Brief Description
As soon as the solar panels have reached a useful temperature level, the liquid in the panel system is pumped through the pressure station and the plate heat exchanger. The feed pump of the Solaris RPS3 P2 control and pump simultaneously pumps the unpressurised buffer water in the domestic hot water storage tank through the plate heat exchanger where it absorbs the heat given off by the solar panel circuit. - Page 9 For hydraulic connection of the RPWT1 plate heat exchanger to the unpressurised tank circulation system of the hot water storage tank.

System concepts Installation ROTEX solar systems are normally installed in accordance with the system concepts shown in the following. This also includes the possibility of connection on the opposite side of the flat solar panels in each case. The high-output flat solar panels can be mounted on different types of roofs. For more information on installation of solar panels see: –... - Page 12 9. Install press-fit elbow (Ø 22/Ø 18 mm). 10.

Operating and display components for the R3P control systems Operation of control systems Due to continuous improvements for optimum use of the Solaris RPS3 P2 control and pump unit, the Solaris R3P control has been fitted with an update function. Therefore, some functions described in this chapter are applicable to specific software versions only. -
