TM200 thermostatic mixing valves provide control of the water temperature and are used: - For
centralised control on hot water supply units or for localised control adjacent to point-use outlets. Or
for use with solar-heated hot water units with dual energy source. - In heating systems with underfloor
heating or for limiting boiler return temperatures. Where a system includes a hot water circulation
circuit, a KB191 return flow retarder unit (see accessories) must be fitted to prevent cold water
backfeeding and cooling the mixed water at the outlets.

Additional description • Highly sensitive thermal element with good all-round water
temperature sensing, even at low flow rates
• Simple setting of the required water temperature
• Scald protection - the hot water inlet is automatically cut off if 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
• Inner components are of scale-resistant materials
