The sensor of the anti-freeze thermostat is an immersion sensor
which gets directly in contact with the cold water. The control unit of
the anti-freeze thermostat is housed in the control cabinet.
The yellow LED K1 lights up during normal operation.
Below the set value the frost protection mode is triggered and the
LED goes out. Above the set value plus the hysteresis, the frost pro-
tection mode is cancelled and normal operation is continued.
