TM50/TM200/TM300SOLAR

Thermostatic mixing valve with scald protection

for solar installations

Product specification sheet

Application

Thermostatic mixing valves of this type are used for central regu­lation of the water temperature in solar-powered, bivalent water
heaters.

A cold water break can be fitted in the circulation line in water
heater systems, which prevents cold water from mixing at the
extraction point via the circulation line.

Special Features

• Highly sensitive thermal element with good all-round water­temperature sensing, even at low flow rates

• Simple setting of the required water temperature

• Scald protection - the hot water inlet is automatically cut off if

TM200SOLAR

the cold supply fails provided that the hot water inlet tempe­rature is at least 10 K higher than that of mixed water setting

• The cold water inlet is automatically cut off if the hot supply
fails

• Meets KTW recommendations for potable water

• Inner components are of scale-resistant materials

heaters.

A

The highly sensitive thermal element located in the outlet of the
valve controls a plug which regulates the flow proportions of cold
and hot water in relation to the mixed hot water setting selected.
Soft seatings are fitted to both hot and cold water inlets.

They provide:

• A positive hot inlet shutoff if the cold water supply is inter­rupted, provided that the hot water inlet temperature is at
least 10 K higher than that of the mixed water setting.

• The cold water supply is cut off if the hot water supply is inter­rupted.
