Application
Sizing example
Thermostatic temperature controllers for singlefamily houses and flats are used to control the
flow temperature in storage domestic hot water
and heating systems. With their fast opening
and closing, they protect the heating coil
from scaling and ensure a long lifetime for the
equipment installed in the system.
