Description

The pulse counter allows you to monitor gas, water and electricity consumption as well as electricity production.

Overview

Operation

The module has three inputs. It can therefore connected to up to three metres. The pulse counter counts the pulses and
converts the sum into m³ or kWh. The scale factor of the pulses (e.g. 1 pulse = 10 litres) and the meter type (gas, water or
electricity) can be selected via the programming software.
The eco-display shows the total gas, water and electricity consumption and the electricity production, if applicable. The
resident can request a detailed overview of the history of the energy consumption via the touchscreen.

The pulse counter should not be used for billing purposes. Only the data recorded by the meter of the energy
supplier is valid for billing purposes. The data recorded by the pulse counter should be used for information
purposes only.


Selecting the correct measuring module

There are a few options available for measuring electrical data. Based on the number and type of channels you wish
to measure, you can either select an electricity measuring module with one channel, an electricity measuring module
with three channels or a pulse counter for three channels in combination with a meter with pulse output. See Electricity
measuring modules
.

A maximum of 20 channels can be measured per installation

The measuring data is then stored in the memory of the connected controller. How long the connected controller will store this data for will depend on the number of channels. An overview is provided in the table below

Installation

Wiring diagram

Fitting a meter with pulse output

There are three options for fitting a meter with pulse output:

  • An add-on device is available from the wholesaler’s for most gas meters supplied by the energy supplier. This device clips onto the meter housing and generates a pulse whenever a certain amount of gas has been used. In a lot of cases, this add-on device can also be used on existing meters. Contact the gas meter manufacturer for more information.
  • For a newly constructed dwelling, you can ask the customer (building supervisor or architect) to request a gas or water meter with pulse output from the energy supplier.
  • You can ask the installer of the heating or sanitary system to install a separate gas or water meter with pulse output.


Connecting and mounting

Follow the steps below to mount and connect the pulse counter:


  • Ensure that the installation is disconnected from the mains.
  • The cable distance between the module and the pulse output should not exceed 50m.
  • A maximum of three meters can be connected to each module.
  • If you establish a connection with the gas meter, make sure that the pulse output is galvanically isolated from the meter housing. In most cases, an add-on meter interface that generates pulses via an internal
  • magnetic contact switch (reed contact) can be clipped onto the meter.


  1. Press the module onto the DIN rail until it clicks into place. Position the pulse counter preferably in the top row inside the electrical cabinet to keep the SELV cables separate from the 230V cables.
  2. Connect the pulse outputs to screw terminals 1-3.
  3. Connect the mass of the pulse outputs to the common screw terminal COM.
  4. Connect the module to the module before it. Slide the sliding contact of this module to the right until it clicks into the pulse counter. This will ensure that the bus and the power supply voltage are connected.


Programming the pulse counter

Use the programming software to select the currency of your choice: EUR, GBP or SEK. Gas and water consumption are
expressed in m³ and electricity in kWh. The following settings can be selected per channel:

  • channel name.
  • channel type: gas, water, electricity.
  • pulse conversion factor:
    • 1 - 1,000 pulses/m³ for gas and water.
    • 1 - 10,000 pulses/kWh for electricity.
  • in case of electricity: global, consumer, amount generated.
  • in case of water or gas : global or sub-measurement consumption


  • If the voltage at the power supply of the Niko Home Control installation is disrupted, no data will be logged, even if electricity is still being consumed or produced by the switching circuits measured.
  • You will lose all data of a channel if you use the programming software to:
    • remove the channel.
    • change the energy type (electricity/gas/water).
    • change the measurement type.


Error codes

When the module is functioning properly, the STATUS LED will light up in TEST mode only. If one or several errors occur, the LED will blink to indicate the error code of the error with the highest priority. The table below provides an overview of all error codes.
