23:4 Stop temperature differ-
ential for central heating
backup: 4 K.
Switching output sS is
switched OFF when the
temperature at sen-
sor / falls below the
stop point. The stop point
is the sum of the temper-
ature at sensor aÖ and
the value selected for the
stop temperature differ-
ential.
24:40 Start temperature for the
thermostat function
40 °C.
Start temperature for the
thermostat function ≤
stop temperature for the
thermostat function:
Thermostat function e.g.
for reheating. Switching
output sS is switched ON
when the temperature at
sensor / falls below the
start temperature for the
thermostat function.
Start temperature for
thermostat function >
stop temperature for ther-
mostat function:
Thermostat function e.g.
for utilising excess heat.
Switching output sS is
switched ON when the
