Cooling Characteristics
WARNING: This page is about a different car, the 2009 Mercury Milan, 2009 Lincoln MKZ, and 2009 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
- In cool mode, the TED circuits of a given seat are wired in series internally in the DCSM.
- The climate controlled seat system draws approximately 7 amps when in cool mode on high setting.
- In cool mode, the TED can remove up to 8°C (14°F) from the ambient air temperature entering the system.
- There are 3 manual settings based on the LEDs above each seat cool switch button on the HVAC module. The first setting is HIGH (3 LEDs), the second setting is MED (2 LEDs) and the third is LOW (1 LED) then OFF (no LEDs).
- When cooling, the DCSM maintains constant speed of the fans and constant TED supply voltage (duty cycle) in open loop cool mode.
- Seat cooling has a maximum operating duration of 30 minutes.
| Climate Controlled Seat Cool State | TED Voltage | TED Supply Duty Cycle |
|---|---|---|
| HIGH | Vbat | 100% |
| MED | Vbat | 75% |
| LOW | Vbat | 50% |
The climate controlled seat system is deactivated by one of the following actions:
- Selecting the HVAC module setting to manual OFF.
- Turning the vehicle OFF.
If the temperature at one of the TEDs falls below 5°C (41°F), the DCSM will shut down the TEDs and initiate system recovery mode. If the temperature continues to drop below 2°C (36°F), the DCSM will shut down the fans in the affected seat.
