CTC GSi 16

6.1.10

Electric shut-off valve Y47

If you have two heating circuits and wish to have background

heating in heating circuit 2 and the heat off during the summer

in heating circuit 1, you can use an electric shut-off valve

(Y47). Terminal block A13 is powered during the heating

season and not powered in the summer.

6.1.11

DHW circulation (accessory)

The settings for hot water circulation require the installation of an expansion

card accessory.

DHW circulation is connected as shown in the schematic diagram. Pump

G40 is used to circulate the hot water.
