Thermic mixing valve Honeywell TM200-3/4A for domestic hot water

Purpose:

TM 200 thermostatic mixing valve provides control
of the water temperature:

-for centralised control on hot water supply units or for
  localised cotrol adjacent to pointof-use outlets. Or for
  solar-heated hot water units with dual energy source.

-in heateng systems with underfloor heating or for
  limiting boiler return temperatures


Where a hot water supply includes a secondary circulation circuit, a return flow retarder unit must be fitted to prevent cold water backfeeding and cooling the mixed water at the outlets.
