2.10 The temperature constrainer / thermal
fuse
The temperature constrainer
The temperature constrainer (bi-metal) protects the
heating device against high work temperatures that are not
permitted. The temperature constrainer reacts at a
temperature over 107
0
C or 117
0
C and shuts off the
heating device. The temperature constrainer will be set
manually or automatically.
The thermal fuse
The thermal fuse protects the heating devices against high
working temperatures that are not permitted. There is a
fuse element in the thermal fuse that reacts and shuts off
the heating device when the permitted temperature will be
exceeded. A temperature constrainer can also be installed
in the heating device instead of the thermal fuse.
2.11 The regulation thermostat
The regulation thermostat at the heating device
The regulation thermostat takes over the task of
regulation after the working temperature has been
reached. The temperature of the cooling water will be
kept at a fixed temperature by opening and shutting off
the heating device in certain intervals. The thermostat
shuts off at 63 ± 5
0
C and opens at 70 ± 3
0
C.
The external regulation thermostat
The regulation task can be controlled by a regulation
thermostat installed externally. The regulation thermostat
takes over the task of regulation after the working
temperature has been reached. The temperature of the
cooling liquid will be kept at a fixed level by opening and
shutting off the heating device at certain intervals. The
thermostat shuts off at 71 ± 2
0
C and opens at 78 ± 2
0
C
or shuts off alternatively at 62 ± 2
0
C and opens at 70 ± 2
0
C.
A thermostat that shuts off at 35 ± 2
0
C and opens at 42
± 2
0
C can be installed in the heating devices that have
an economy circuit (mode for keeping warm).
