What brand name are either of these controls?

The T55 could be UK or US manufactured by two different manufacturers, and they are two different designs.

A search including the manufacturer will be a more successful search.

My Fujitsu air con keep flashing operation,timer and economy .off the plug took out and on back still the same.took out the batery from remote and put back still the same..plss help me

It's asking you what mode you want to run your unit in. Do you want to run it in heating or cooling (operation), do you want to run it with economizer mode (economy), or do you want to run it with a timer setting (timer). Do cooling, no economizer, and no timer. This will make your unit run off off the setpoint you want. I.e. 72 degrees

I have moved into a new house and there is a halstead quattro combi boiler but I don't have the instruction book and need to know how to set the timer on it

Can you please get a part number? I t might be on the outside of the unit. If not, you'll need to remove the front covers. There should be a nameplate with a model number, serial number, amp, volts, and other info. Let me know what that says.

Took front of air cond. off today to clean and the 2 plastic clip tabs on rt side broke off. Can I get a replacement cover?

Contact the manufacturer of the unit to enquitre about replacement covers.

The easier solution is to use a typical 5/16 hex head screw just like found on HVAC systems everywhere, and replace the plastic tabs with the screws.

If the screws are not self tapping, you may want to predrill the holes in the metal first to make it easier.

Do I fill it with Water?

I don't know why but I kept the instructions -
Instructions are:
Lift the top cover and fill the smaller compartment with water - takes 11 litres from empty. Water level is seen on the window to the front.
Ice packs are placed in the larger compartment (That is all this compartment is for - Not to be filled with water)

Trane XE100 and I am getting an icing condition resulting in a shutdown. The fan apparently was operating but not moving any air through the room vents.When I took a panel off the fan assembly I got plenty...

Sounds like you are low on freon or you have some type of obstruction that is blocking the full flow of air across the coil. 
Go for the simple thing first which is make sure you don't have something blocking the flow (like one time I found a plastic bag from the grocery store that had been sucked into the return grill and when the fan came on it would lay on the A-coil blocking the flow).
If that's not the problem then you are probably low on freon and should have the system charged.
