10.2.2 Water Cycle for space heating
Space heating is operated by Water Cycle 1 or combination of Water Cycle 1 and Water Cycle 2.
Cycle 1 will be direct (high temperature for radiator or fan coils operation) and Cycle 2 will be a mixing cycle in order to have
a second temperature control using mixing valve (low temperature for oor heating operation). Additionally, a motorized
valve can be added in order to close direct cycle when not in use . The oor heating loops (Cycle 2) require a lower
temperature than with radiator or fan coils (Cycle 1). To get these 2 water temperature levels, a mixing station is required.
This mixing station is controlled using the indoor unit by means of a mixing valve / additional pump (WP2) /additional water
sensor (Tow2).
