Delay between turning off and on
There is a built-in delay in order to
avoid unnecessary wear and tear on
internal components and to extend
the life of the thermostat. If you raise
the desired temperature so that the
thermostat comes on, and then lower
it shortly afterwards, it takes four min-
utes before it goes off again.
Key lock button
When you have found a suitable set-
ting for the temperature you can lock
the knob. This prevents the control
being changed accidentally.
See illustration below. First remove
the knob. Then move the two plastic
parts so that they define the interval
required. Replace the knob.
