01 / Understand the meter
Start with what the meter actually does
The VeryCo VC1100 (DINM22-CIP) is a single-phase prepaid energy meter rated at 230V and 5(80)A. It uses STS token-based credit, measures accumulated and remaining energy, supports automatic relay disconnection when prepaid energy is exhausted, and works with a separate Customer Interface Unit (CIU) for customer interaction.
This guide explains what the physical meter does, how prepaid credit is managed, how the customer uses the separate CIU, and which protection, metering and communication functions are documented by the manufacturer.
02 / How it works
Follow the electricity and the prepaid credit
See how the VC1100 measures energy, manages prepaid credit, uses the separate CIU and controls the load through its internal relay.
02
The meter keeps track of remaining prepaid energy
The VC1100 records both total accumulated energy and the remaining prepaid energy available to the customer.
03
The customer interacts through the separate CIU
The Customer Interface Unit provides the keypad, LCD and status indicators used for customer interaction with the prepaid meter.
04
A 20-digit STS token adds prepaid energy
The manufacturer documents STS encryption and 20-digit token entry for adding prepaid energy to the meter.
05
Low-credit warnings alert the customer
The meter provides configurable low-credit warning levels and visual indications as the remaining prepaid energy falls.
06
The relay disconnects when prepaid energy is exhausted
When the remaining energy reaches zero, the meter can automatically disconnect the load, subject to the configured operating and overdraft settings.

Function explained
Bidirectional active energy measurement
The VC1100 measures bidirectional active energy; the manual states that reverse energy is accumulated to positive energy.

05 / Where to use it
Match the meter to the property
A meter should be selected for its application, not simply because it is prepaid.
Single-phase residential supplies
EDM selection guidance: consider the VC1100 where the property uses a compatible single-phase 230V supply and the 5(80)A meter rating matches the electrical requirement.
Rental and managed properties
EDM selection guidance: the separate CIU can make customer interaction more convenient while the main meter remains at its installed supply position.
Complexes and multi-unit environments
EDM selection guidance: suitable sites may use individual VC1100 meters where each unit has an appropriate single-phase supply and installation design.
06 / Selection guide
Should you choose this meter?
Use the requirements below as a practical starting point, then confirm the site-specific technical requirements before installation.
Choose the VC1100 when...
- You need an STS prepaid electricity meter for a compatible single-phase 230V supply.
- The required current range is compatible with the VC1100 5(80)A specification.
- You want a separate CIU for customer token entry and meter interaction.
- Automatic prepaid relay disconnection and low-credit warning functions are required.
- The project can be installed and commissioned in accordance with the manufacturer's wiring, pairing and technical requirements.
Check these points before ordering
- Confirm that the supply is single phase and nominally 230V.
- Confirm that the expected electrical load is suitable for the 5(80)A meter rating.
- Confirm the wiring, protective equipment, enclosure and installation arrangement with a suitably qualified electrical professional.
- Confirm the CIU pairing and site communication requirements using the manufacturer's documented commissioning procedure.
- Do not assume PLC communication: this manual documents near-infrared and RS485 meter ports, but does not identify the CIU link as PLC.
- Confirm whether any advanced settings such as overdraft, over-power thresholds, tariffs or postpaid mode are required before commissioning.

09 / Questions
Common questions about VC1100
Is the VC1100 a single-phase prepaid electricity meter?
Yes. The manufacturer identifies the VC1100 / DINM22-CIP as a single-phase prepaid energy meter rated at 230V and 5(80)A.
Does the VC1100 use STS tokens?
Yes. The manual states that STS encryption and 20-digit cryptographic tokens are used for prepaid energy recharge and supported technical functions.
Does the customer use a separate CIU?
Yes. The manual shows a separate Customer Interface Unit with an LCD, keypad and status indicators and provides a CIU-to-meter pairing procedure.
Does the manual say the CIU uses PLC?
No. This technical manual does not identify the CIU communication method as PLC. It documents near-infrared and RS485 communication ports on the meter.
What happens when prepaid energy reaches zero?
The manual states that the meter automatically disconnects the relay when remaining prepaid energy reaches zero, subject to configured overdraft behaviour.
Does the VC1100 have tamper protection?
Yes. The manual documents tamper detection and responses for conditions including cover opening, reverse wiring and strong external magnetic fields.
Can the meter keep historical consumption information?
Yes. The manual documents historical monthly energy data, daily and hourly frozen energy information, recharge history and multiple event counters.
Can it operate in postpaid mode?
The manual documents switching between prepaid and postpaid modes through supported configuration methods. EDM should confirm the intended operating mode before commissioning.
Understand it. Select it. Install it correctly.
