Control Description

Cooling/heating Function Control During Power Supply Position ON

When the power supply position is ON (vehicle condition is not READY while power switch is ON), VCM allows the operation of cooling/heating function control in the status that EVSE is connected. However, start of cooling/heating function is allowed only while charging is in progress. Refer to "DESCRIPTION " (automatic air conditioning system with heat pump system) or "DESCRIPTION " (automatic air conditioning system without heat pump system) for details of cooling/heating function control during power supply position ON.

NOTE: If the Li-ion battery available charge gauge level is lower than Level 2, the A/C does not operate during battery charge.

Climate Ctrl. Timer Control

When all of the following conditions are satisfied, VCM activates the timer air conditioner so that the in-vehicle temperature reaches in-vehicle setting temperature^*1 before the scheduled departure time^*2 .

Timer of Climate Ctrl. Timer is ON
There is AC power input during charging (or in a state where AC power input is possible).

VCM activates the EV system 2 hours before the scheduled departure time. The A/C auto amp. judges the necessary operating time of Climate Ctrl. Timer within the range between 0 and 2 hours according to the ambient temperature and interior temperature and sends the data to VCM. VCM calculates and judges the operating time required for activating the Climate Ctrl. Timer, according to the scheduled departure time and the received data.

NOTE:

When turning ON the power switch during Climate Ctrl. Timer is activated, the air conditioning control switches to normal.
When the timer charge and timer air conditioner operate simultaneously, perform air conditioner power distribution according to the following settings.
- Models with 7 inch display: timer priority setting that are set on the navigation screen
- Models without 7 inch display: Climate Ctrl. Timer priority
*1: The in-vehicle setting temperature can be set as per the following.
- Models with 7 inch display: A/C temperature that are set on the navigation screen
- Models without 7 inch display: 25°C (unchangeable)
*2: Set the scheduled departure time from the navigation screen (models with 7 inch display) or from the vehicle information display on the combination meter (models without 7 inch display).

Remote Climate Control

When VCM receives the remote climate control request signal from the TCU, the air conditioning is operated.

Remote air-conditioning operates as follows.

Condition	Operating time (min)
Charge connector is not connected.	15
When connecting EVSE (with AC input)	15 - 120
During quick charge	15 - 120

NOTE: When the power is turned ON during remote climate control is activated, the remote air conditioning is ended.

De-ice Control (Automatic Air Conditioning System With Heat Pump System)

When VCM receives a de-ice request signal from A/C auto amp. and it is in the normal charge mode or quick charge mode, VCM turns the A/C relay ON and sends a de-ice permission signal (permission) to A/C auto amp. A/C auto amp. operates the de-ice function due to receiving a de-ice permission signal
When the charge mode is completed due to full charge or timer charge completion while the de-ice function is operating, the de-ice function continues to operate. The charge status indicator 3 blinks while the de-ice function operates after charge completion.

NOTE: If the charge connector is disconnected from the charge port, VCM sends a de-ice permission signal (precaution) and the de-ice function is stopped.

After the compressor operation is stopped due to de-ice control function, VCM operates the cooling fan according to a cooling fan speed request signal that is received from the A/C auto amp.
For detail of de-ice control function, refer to "AUTOMATIC AIR CONDITIONING SYSTEM: HEAT PUMP SYSTEM CONTROL ".
