8-3.	5) Mixing Valve control (2-temperature heating control)
Hydro Unit	To set different radiator unit supply temperatures or floor heating supply temperatures, the unit performs Mixing Valve
Control	control.
	When Mixing Valve "Yes" is selected, the unit controls Mixing Valve every 4 minutes (FC) based on the difference TSC_Δ
	T between the Zone2 set temperature and TFI (floor inlet water temperature sensor) temperature as follows:
		TSC_ΔT	2	TSC_ΔT	-2	TSC_ΔT < 2	-2 > TSC_ΔT
		Control value	+ 1 step (Open)			± 0 step	- 1 step (Close)
		Initial value	Driving range			1 step	Control cycle
		6	0-12		3 WV move 7.5 degs		4 mins (FC)

For 2-temperature control, DP_SW12-3 Zone2 "Yes" must be selected.
