Fit thermostat cartridge

Sirius 1850 to fit the thermostat does the black end go in first to the body of the cartridge Your video is brilliant but when the thermostat is inserted into the cartridge the thermostat goes out of frame.

Didn't notice that it went out of frame i'll check it and add a sticky.

Anyway the black bit points out and the brass bit goes into the wall.
