Cooling Characteristics
WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. 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.
- In cool mode, the TED can remove up to 8°C (14°F) from the ambient air temperature entering the system.
- The system control settings are based on the 3 indicators above each climate controlled seat cool switch button on the HVAC module. The first setting is HIGH (3 indicators), the second setting is MED (2 indicators) and the third is LOW (1 indicator) then OFF (no indicators).
- When cooling, the DCSM maintains constant speed of the blowers and constant TED supply voltage (duty cycle) in COOL mode (refer to the following table).
| Cooling Mode | 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 shuts down the TEDs and initiates system recovery mode. If the temperature continues to drop below 2°C (36°F), the DCSM shuts down the blowers in the affected seat.
