REMOTE START CLIMATE OPERATION

[doczenith1]

Can any of you current owners clarify what the manual states. In particular my questions are:

1.) Manual mode: It appears that if I leave the climate control in any position other than Auto when I turn the truck off that when I remote start the truck it will come on with with max A/C or floor/defrost and I'm assuming the fan speed I left it on?

2.) Automatic mode: I'm assuming this mode happens when I turn the truck off with the climate control set to automatic. Looks like the way to go if you want the climate controlled seats to activate.

3.) Automatic mode: For cold weather conditions where does the system direct the warm air? I would assume floor/defrost but you never know.

Manual climate control
For hot weather conditions:
• The climate control system will be set to MAX A/C.
For cold weather conditions:
• The climate control system will be set to provide maximum heating
in (floor/defrost) mode.
• Rear defrost/heated mirrors (if equipped) will be activated.
For moderate weather conditions:
• The interior cabin will be heated, cooled or off, based upon the
previous operating state (last ignition-on cycle).
• Rear defrost/heated mirrors (if equipped) will be deactivated.

Automatic climate control
For hot weather conditions:
• The interior cabin will be cooled to 72°F (22°C).
• The cooled seats (if equipped) will be set to high.
For cold weather conditions:
• The interior cabin will be heated to 72°F (22°C).
• The heated seats (if equipped) will be set to high.
• Rear defrost/heated mirrors (if equipped) will be activated.
For moderate weather conditions:
• The interior cabin will be heated, cooled, or off, based upon the
previous operating state (last ignition-on cycle).
• Heated/cooled seats (if equipped) will be deactivated.
• Rear defrost/heated mirrors (if equipped) will be deactivated.

(Yes, I've read the entire manual and all supplements and I don't even have the truck yet )

Its my understanding that in Auto mode, the computer will turn on the appropriate climate and seat settings based on the temp.

HVAC - DATC (Dual Automatic Temperature Control) System

When the remote start feature is used, the climate control system automatically sets certain parameters in an attempt to achieve a comfortable cabin temperature. These parameters are set based on outside air temperature. During remote start, the outside air temperature is continually evaluated and HVAC system behavior can change if the outside air changes between cold, moderate and warm temperatures.

For cold ambient air temperatures as determined by the HVAC module AUTO mode to request heat:

• the airflow mode is set to FLOOR/DEFROST
• the temperature is set to 72° F (22° C)
• the blower speed is set to AUTO
• the air inlet mode is set to AUTO
• the auxiliary electric heater is enabled if needed (diesel only)

For moderate ambient air temperatures as determined by the HVAC module AUTO mode to request heat or cooling:

• the airflow mode is set to the AUTO
• the temperature is set to the last user setting (Temperature setting is limited to 65° F (18° C) minimum and 85° F (29° C) maximum. If the temperature is set above or below that range, it will use the minimum or maximum value.)
• the blower speed is set to the AUTO
• the air inlet mode is set to AUTO
• the auxiliary electric heater is enabled if needed (diesel only)

For warm ambient air temperatures as determined by the HVAC module AUTO mode to request cooling:

• the airflow mode is set to AUTO
• the temperature is set to 72° F (22° C)
• the blower speed is set to AUTO
• the air inlet mode is set to AUTO
• the auxiliary electric heater is not enabled (diesel only)


HVAC - EMTC (Electronic Manual Temperature Control)

When the remote start feature is used, the climate control system automatically sets certain parameters in an attempt to achieve a comfortable cabin temperature. These parameters are set based on outside air temperature. During remote start, the outside air temperature is continually evaluated and HVAC system behavior can change if the outside air changes between cold, moderate and warm temperatures.

For cold ambient air temperatures (below 32° F (0° C)):

• the airflow mode is set to FLOOR/DEFROST.
• the temperature is set to full HOT.
• the blower speed is set to HIGH.
• the air inlet mode is set to fresh air.
• the auxiliary electric heater is enabled if needed (diesel only).

For moderate ambient air temperatures (between 32° F (0° C) and 80° F (27° C)):

• the airflow mode is set to the last user setting.
• the temperature is set to the last user setting.
• the blower speed is set to the last user setting.
• the air inlet mode is set to the last user setting.
• the auxiliary electric heater is enabled if needed (diesel only).

For warm ambient air temperatures (above 80° F (27° C)):

• the airflow mode is set to MAX A/C.
• the temperature is set to full COOL.
• the blower speed is set to HIGH.
• the air inlet mode is set to RECIRC.
• the auxiliary electric heater is not enabled (diesel only).


HVAC - Auxiliary Electric Heater (DATC and EMTC)

The AHCM (Auxiliary Heater Control Module) activates if all of the following conditions are met:

• The ignition switch is in the RUN/START position
• The engine is operating at greater than 500 rpm
• Any ON mode is selected on the HVAC module
• The temperature setpoint is greater than 80% of the highest setting (EMTC only, DATC uses software algorithm based on interior temp and set point)
• The engine coolant temperature is less than 185° F (85° C)
• No alternator faults have been recorded and alternator is not at full capacity

The AHCM deactivates if any of the following conditions are met:

• The ignition switch is in the OFF or ACC position
• The engine coolant temperature is greater than 185° F (85° C)
• An alternator fault has been detected or the alternator is fully loaded due to external electrical loads
• The engine is operating at less than 500 rpm
• The auxiliary heat request is NO from the HVAC module (EMTC or DATC)


Seats

When the vehicle is started using the remote start feature, the driver/passenger climate controlled seat activates in full heat mode when the outside temperature is less than 32° F (0° C) and full cool mode when outside temperature is greater than 80° F (27° C).


Mirrors

When the vehicle is started using the remote start feature and the outside temperature is less than 32° F (0° C), the heated mirrors will be activated.


Rear Defroster

When the vehicle is started using the remote start feature and the outside temperature is less than 32° F (0° C), the rear defroster will be activated.

I live in Alaska and I have yet to notice my heated seats come on when using the remote start. Its been between 0-30 degrees since I bought my truck and i use the remote start every morning. Does my truck have an issue??

You have to set the climate controls to AUTO for it to work.

Depends... When using remote start the ON lights for the heated seats will NOT be illuminated even if they have been activated. The seats will also return to the previous user setting once the vehicle has been started with the key. These two operational factors have already confused a couple of '11 owners into thinking the seats are not working.

Now if they are simply not working, then yes there is likely a issue...

[tlew79]

So the indicator lights for the heat button do not illuminated when in remote start...I was also wondering if mine were working. Last couple of days the temp as been 22f, when I get in after the truck as been remote started and idled for about 5 minutes the seats are stone cold. Also have the climate control set to Auto, guess I will let it sit longer and see if the seats actually warm up.

[doczenith1]

I don't remember the heated seats in my '02 ever feeling warm to the touch after being on for 5-10 minutes but when sitting in the seats you do start to feel the heat after a minute or so.

[Mojoryb]

Considering that these CGI blocks take for ever to warm up, your only heat during a remote start in a freeze, if you don't have the auxillary, is the seats. I've been in discussions with my dealer here in BC, Canada about the way remote starts used to deal with the climate controls...however you left them, & according to him there are quite a few folks wanting Ford to flash the remote back to the old way. I agree. Also, if I leave the mirrors & the seat on when I shut it down, they do not return to those settings when the key is inserted after a remote start. There's my 2 bits, for it's worth.
