A user interface unit (UIU) is a remote access terminal for STS prepayment meters. The device is placed inside the user's premises, while the energy meter is mounted outside and mostly not direct accessible. Some meter manufacturers are using the term customer interface unit (CIU). The functions are the same.
The main purpose is to charge the meter with credit. By various short-codes, it's possible to do many kinds of queries for meter status and consumption. The short codes are not unified, so refer to your user manual for operation.
UIUs are paired with the energy meter when leaving our factory. Depending on the utility order, CLOU interface units are communicating with the meter by radio frequency (RF), power line (PLC) or by wired RS-485.
If the UIU is not communicating with the energy meter, you can pair it again by typing 1593570 and the 11 or 13 digit meter number, then press the enter key (red or blue). The meter number is printed on the meter and on your customer card, which you use to buy credit.
After successful pairing, the display will show OK.
Note: This is only working for CLOU energy meters.
There can also be other reasons for a communication fail. If the UIU is connected by power line and you are disconnected, batteries need to be inserted in the UIU to recharge the meter or query the status. If this meter is in tamper mode, a recharge is impossible before clearing the tamper.

Can you" Clou" provide tamper or bypass code for your company meters? Our services provider are not reliable. Also I need a way to solve communication failure to meters. To a point a meter can't display it's no. On CIU.
All codes are encrypted generated by your service provider. Meter manufacturers can not generate meter specific tokens after encryption. This is an essential part of the STS security.
I cant find my meter number. And I try typing 65 on the UIU but it's not responding. It's not connecting. Please what do I do? How do i get my meter number?
The meter number is printed on the meter and its mentioned in your utility power contract.
How do i get my tamper code
My meter keeps rejecting the token every time I try to put in the token. How can I get this done?
If the display shows that the token is rejected, this token was not issued for your meter number.
I want token code to clear my meter tempa , how me I do
You can visit your Nearest vendor for Temper Code
That's true. Only the vendor can generate the code.
Have you any laptop software configurator for this unit?
The user interface unit is programmed by the manufacturer based on model type and meter configuration. There is no additional software needed.
Sorry, I mean configuration software for metering unit itself, not for UI unit
The meter configuration software is property of the utility or power company. It's special protected and for a limited number of users. Only the utility can make eventually required modifications.
I used code 1593570 to feed token using my neighbors c I u 5 weeks ago.now I try to feed my token but the units goes to the ciu I paired with how can I cancel?
The units are accepted only by the meter no. for which you have purchased the credit. The CIU itself is only the transmitter.
Is it advisable to leave my user interface unit CL710K11B powered on always?
It's recommended to give you a status overview, but it's not mandatory necessary.
I misplace my meter number please how can I retrieve it
The meter number is printed on the meter itself. You can also find it on your power supply contract.
hello. goodmorning sir. kindly rectify me about this l was given this code ‘027777777' for pairing itron CIU with another meter but it didnt work for me. where do l connect the ciu when pairing it with another meter??, do l put it in a socket/not??? if in socket so where??(for the meter to pair with/in its activated line)
I don't know Itron meters in detail, but the procedure is the same for all meter manufacturers. You enter the pairing code (for Itron 027777777) and your 11 digit meter number. Then press Enter (or the arrow symbol) bottom right on the keypad.The CIU needs to be connected to a power socket. If the power is cut, you need to use batteries (not sure if Itron is supporting this).
