6. Cold Draft: In VRF systems, when load is very low and
only few units are working in a system, it is possible that
discharge air temperature is reduced below comfort value.
With this new option HITACHI improves comfort for these
situations by setting unit to Thermo OFF when discharge air
temperature is below comfort temperature and set unit again
to Thermo ON when temperature will be again inside comfort
range.
