13 Cylinder thermostat
The cylinder has a suitable thermal cut-out for the pri-
mary heating circuit (
12
) and solar circuit (
9
) and a cyl-
inder thermostat (
13
).
i
Before wiring the control components, dismantle
the casing (
5
) to facilitate work on
the components. When reinstalling the casing,
use the cutouts in the casings for routing the
cables.
