Typically two pressure sensors determine the presence of adequate draft. Could be defective sensor, draft motor, control board, or obstruction in vent.

Here is an Article that I found that has some useful information for you. http://airmaster.net/troubleshooting/carrier-window-room-air-conditioner-troubleshooting CF means Cooling Fail. Check us out online at AC Services Boca Raton

Do you have the model number/serial number?

do you have a remote control? from there click mode until it is on heting

No.replace thermostat

It does not appear to be. The z-wave has a site that you can check, Neither carrier or z-wave show your model as being compliant. The industry is in a big dispute right now over protocols on home automation standards and it could be worth waiting it out..

Was the problem solved..
I am facing the same problem for last 8 months
But the technician is not able to solve it..
They don't even know what bL code is for

Please let me know if u were able to solve this problem.

Economiser. They have a thermal switch that opens at below a certain temperature to lock out a compressor and opens an outdoor damper to let cool fresh air in instead of cooling it while exhausting return warm air. This at 60*F and below outdoor ambient temperature.
If you read the diagram the outdoor temperature sensor is found there, phisicaly located typical straight down on lower part of the unit or one side.
In case of problem, short the two words together to achieve electrical continuity and to bypass the sensor.

I am assuming you have the new Infinity Touch control (black). If the screen is blank, you've either lost low voltage power (an issue at your furnace) or the unit isn't properly seated on the backplate. Pull the thermostat off of the wall and reseat it properly and if this does not work, you'll probably need a pro to come troubleshoot low voltage issues.

The green leaf is "eco mode." It generally will reduce the running pressures of the system, meaning you spend less on energy and have longer runtimes, but it will reduce cooling capacity. On the less brutal days this is a great option. It's better for the system and better for the energy bill. However, there WILL be days where eco mode simply won't keep up.

Please provide me with a model and serial number off of the unit for me to be able to move forward with assisting you!

Sounds like you wired it wrong.

Is it losing voltage? Need to be sure.
