SOURCE: Fujitsu Heat Pump - problems
I had the same problem. The heater did not work in heating mode. However it was OK in air-conditioning mode. The operation light and the timer light blink twice and then the operation light blinks for 5 times followed by few seconds non blinking, then the cycle repeats again. I have read on the internet that you better unplug the power cord and then plug it again so that the heater re-sets itself. My only problem was that my heater is directly plugged to the power with no visible plug. So I went to the main distribution board and put off the power for about 20 seconds for the whole home. HOORAY!! The heater worked after that.

If I see a code blinking and all is normal as far as I can tell it means something is in a time out mode and counting down to energize. This may not be the case but let it run and blink for a few hours and see if it comes on.
Mark your watch so you can see how long it takes to change or start.
If it does start then you know about how long it will take to recycle.
Assuming you have changed the batteries in the remote (if you have such), and it does this again do not use the remote again, if possible. Try it with manual only. Remote - remove batteries, this will eliminate the remote as the cause.
Next is find the legend of the codes for your unit. Sometimes they are located by the wire diagram on the unit its self, under the wire terminal panel.
If this helps you please rate me as high as possible. If it gets you on the track and need more help tell me what you did and what you found, post it and I'll post back asap.
Thanks for using fixya. and Good Luck.

Testimonial: "Thanks for the advice. It turned out that we had a blackout after the AC had started playing up. The blackout seems to have sorted out the problem.Thx"
Below is an extract straight from the fujitsu service manual:
Compressor location error
The compressor speed does not synchronze with the control signal. (Including start up failure of the compressor).
> permanent stop.
Check if 2-way valve or 3-way valve is left open.
Check the compressor (Winding resistance value, loose lead wire).
Refrigeration cycle defective (Refer to after mentioned "refrigerant cycle diagnosis")
