Temperature limit stop
If the temeprature limit stop should be 43 °C, use handel ref.

Prevention of frost damage
When the domestic water system is drained, thermostat
mixers must be drained separately, since non-return valves
are installed in the hot and cold water connections.
The complete thermostat assemblies and non-return valves
must be unscrewed and removed.

with special valve grease.
Shut off cold and hot water supplies.
