If a higher temperature is desired, the 38 °C limit can be
overridden by pressing button (W1), see Fig. [11].
Prevention of frost damage
When the domestic water system is drained, thermostats 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.
Maintenance
Inspect and clean all parts, replace as necessary and lubricate
with special grease.
Shut off cold and hot water supplies.
