V8 VRF Indoor Units
4.3 Start and Stop Control
Indoor Unit judges the operation state according to the difference value between detected indoor temperature (T1) and
set temperature (TS). When the indoor temperature reaches the set one, Indoor Unit shut down; when the indoor
temperature exceeds the set one, Indoor Unit start running.

Objective
1. Ensure comfort. When the indoor temperature of indoor return air reaches the temperature range set by the user, if
the IDU fails to shut down, the room temperature will deviate from the expected value of the user and reduce the
comfort of the room.
2. Energy saving. When the temperature of the return air reaches the temperature range set by the user, if the IDU fails
to shut down, the air conditioning system will continue to operate inefficiently under the condition of low indoor load,
with low energy efficiency and no energy saving.
