How to install the MCO A2 Multisensor

The instructions in this guide support the pairing of an MCO A2 Multisensor to the Switchee smart shermostat. They should only be followed by a qualified heating or electrical engineer who has achieved the Switchee Installer Accreditation.

warningInstallation must be carried out by a competent person in accordance with BS 7671 and applicable UK regulations.

Overview

MCO A2 Sensor

The MCO A2 Sensor is a mains powered air quality sensor that reports CO2 (ppm), Air Temperature and Relative Humidity. It is our recommended choice where monitoring of CO2 is required or where temperature/humidity monitoring is required in additional areas of the home (e.g. mould concerns in one particular room). It measures the following properties:

  • Air Temperature (-10 ~ 50℃)
  • Relative Humidity (5%RH ~ 95%RH)
  • CO2 / carbon dioxide ( 0 ~ 5000 ppm)
  • PM2.5 particulate matter (0 - 500 ug/m3)
  • VOC volatile organic compounds (0 - 65000 ug/m3)

Installation

When installing the MCO Home Sensor, it is important to consider the location of where this will be installed. There are two tips for this:

  1. The MCO Home Sensor must be installed vertically on a wall. This will be ideally in a location where significant data would be recorded, such as the bedroom or kitchen (provided the Switchee isn’t located in either of these)

  2. The bottom of the sensor must not be covered. This is because the sensors are located at the bottom of the MCO Home Sensor, and by obstructing this it will lead to insignificant and erroneous data being collected.

It is recommended to fit the sensor into a back box as the sensor has a green terminal block on the back.

Pairing to the Switchee

  1. Access the Z-wave pairing menu on the Switchee via: 
    1. Tap on the Spanner (top left)
    2. Next x2 
    3. Admin (Pin is 0123)
    4. Z-Wave Sensors
  2. Select ‘Pair/Unpair Sensors’
  3. Select ‘Pair new sensor’. This puts the Switchee into pairing mode for 2 minutes. 
  4. Press the side button on the A2 sensor 3 times in succession and the LED will keep flashing until paired. Once paired, the Switchee will indicate that a new device has been included/added. 
  5. To verify successful pairing, select ‘Sensor Readings’ and wait a few minutes for the sensor data to populate. Example shown below:

Unpairing from the Switchee

  1. Access the Z-wave pairing menu on the Switchee via: 
    1. Tap on the Spanner (top left)
    2. Next x2 
    3. Admin (Pin is 0123)
    4. Z-Wave Sensors
  2. Select ‘Pair/Unpair Sensors’
  3. Select ‘Unpair existing sensor’. This puts the Switchee into unpairing mode for 2 minutes. 
  4. Press the side button on the A2 sensor 3 times in succession. Once unpaired, the Switchee will indicate that a new device has been removed/excluded.

LED indicator

When the device is powered on, the LED indicator will light up red. To turn off the LED, press the side button once; to turn the LED back on, press the side button again. 

Factory resetting the A2-ZW

Press the side button 10 times in succession to restore the sensor’s factory setting.
