9 DETECTION CONTROL BOARD
9.1 Gate-control Function
This detection control board is only suitable for Gree multi-variable (GMV) indoor unit with gate-control
function. The AC will run after plugging in gate-control card and stop running after plugging out the card. Upon
plugging out the card to stop the unit, the running states of the unit will be memorized. After plugging in the
card, the unit will be under standby state or resume running according to settings. The AC will run when the
customer plugs in the card and automatically stop when he plugs out the card, which ensures unit off after
leaving of persons and saves energy.
Fig.1 is about simple sketch for communication network of detection control board for GMV series.

9.2 Working Process of Gate Control
1) If the gate-control card is not plugged in after powering on the complete unit, the indoor unit will be in
the state without gate-control function and can be operated by remote controller or buttons on it.
2) Powering on the AC and plugging in the card, the unit will be in the state with gate-control function after
5-second detection. The present running state of the AC won’t be affected (the unit on/off state will be kept)
after plugging in the card. If plugging out the card, the AC will automatically stop after 5-second detection.
Once plugging in the card, indoor unit will be considered as the one with gate-control function, which can
be canceled only after powering off and then powering on the unit.
