Taking out of operation
6.1
Temporary shutdown
CAUTION
A heating system that is shut down can freeze in the event
of frost and may suffer damage.
▪ If there is a danger of frost, start the entire ROTEX heat-
ing system up again and activate the frost protection
function or take the appropriate frost protection meas-
ures for the hot water storage tank (e.g. by draining).
INFORMATION
If there is a risk of frost for a few days only, the very good
heat insulation of the hot water tank means that it need not
be drained as long as the storage tank temperature is reg-
ularly observed and does not fall below +3 °C. This does
not, however, provide any protection against frost for the
connected heat distribution system.
If the storage tank temperature does fall below +3 °C, the
STB of the electric immersion heater automatically triggers.
This prevents consequential damage to the electric immer-
sion heater caused by frost when starting up again.
6.2
