Thermostats - Electrolux Compact Service Manual

12. Thermostats

The thermostats are pressed into the
tubular mountings in the plastic chassis.
They measure the temperature on the
outside of the plastic wall, which leads to
a certain difference between the water
temperature and
temperature.
However, the specifications of the
thermostats take this into account. (In one
particular case, the same thermostat is
used for two different temperatures.
This is possible because the thickness of
the chassis is different at the two
thermostat mountings.
The thicker the wall, the greater the
temperature difference and the higher the
water temperature.)
Depending on the Programme selected,
the thermostats will be switched in, and
will interrupt the power supply to the heater
element via the programmer when the
water has been heated to the required
temperature.
As in the case of al! other components,
there is a certain amount of tolerance on
the nominal temperature
thermostats.
For the breaking temperatures, the
tolerance is ±3°. There is also a "differen-
tial", i.e. a difference between the
temperature at which the thermostat opens
the circuit and the temperature at which it
returns to the original position. This diffe-
rential is 8°C.
The breaking values are adjusted to give
the following water temperatures: 45, 55,
65 and 72'C.
