Heating controller WHC/WHC +
WITA heating controllers (WHC) are advanced heating controllers, installed in standard-dimension
housings of 144 x 96 mm. They have been developed for the control of room heating or cooling as well as
domestic hot water heating in single-family homes. They provide control for up to 2 heating circuits,
enable switchover between heat sources, and the protection of the return line during the storage tank
loading.
They are used for heating systems with one or two boilers, a heat pump, a storage tank, and a solar system.
