Thermic mixing valve Honeywell TM200-3/4A (for underfloor heating and domestic hot water)
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.
