How to Use With Google Assistant

Usage Guidelines

When asking Google Assistant

Make sure you speak at a normal pace. Do not slow down with large pauses between words as Google Assistant can interpret this as the end of a request.

  • Turning On Heat Pump
    When you ask Google Assistant to turn on your heat pump, it will switch on to the last setting it was set to.
  • Setting Temperature of Heat Pump
    When you ask Google Assistant to set the temperature of your heat pump, the following logic applies.

    If the heat pump is currently off
    Your request will turn on the heat pump, set the temperature and adjust the mode to either heating or cooling according to your set temperature compared to the room temperature.
    For example, if you ask Google Assistant to set the temperature to 24 degrees, and the actual room temperature is 21 degrees, the heat pump will adjust automatically to Heating Mode.

    If the heat pump is currently on
    Your request will only adjust the temperature.

  • Understanding Google Assistant's Reply - Mode
    When you ask Google Assistant to set the temperature of your heat pump or ask what the heat pump is set to, Google Assistant will reply using the words ‘AC’ for cooling, ‘Heat’ for heating, ‘Auto’ for auto or ‘Fan Only’ for fan.

    If you are in Cooling Mode
    Google Assistant will reply “Cooling is set to 21”

    If you are in Heating Mode
    Google Assistant will reply “Heating is set to 21”

    If you are in Auto Mode
    Google Assistant will reply “Auto mode and is set 27 degrees”

    If you are in Fan Mode
    Google Assistant will reply “Fan only mode ”

  • Understanding Google Assistant's Reply - Room Temperature vs Set Temperature
    Google Assistant can tell you what the actual room temperature is, or what the heat pump's set temperature is (what you are trying to heat or cool to). The following logic applies to a heat pump named 'Lounge':

    Room Temperature
    Note: When asking for the room temperature you are asking for the room name not the heat pump name. In this example the room name is: Lounge.
    Ask, “Hey Google, what is the Lounge temperature?”, Google Assistant will reply “Heating is set to 21 with a current temperature of 19”

    Heat Pump Set Temperature
    Ask, “Hey Google, what is the Lounge set to?”, Google Assistant will reply withth any of the following “Heating is set to 21 degrees”, “Cooling is set to 21 degrees” or “Heat cool mode is set to keep between 21 and 21 degrees” for Auto.

  • Setting and understanding Heat Pump Fan Speeds
    Google Assistant understands 3 fan speed modes of your heat pump (low-medium-high-auto).

    Set the Fan Speed
    Ask, “Hey Google, set the Lounge apeed to low”, Google Assistant will reply “Alright the Lounge is set to low”

    What is the Fan Speed
    Ask, “Hey Google, what is the Lounge speed?”, Google Assistant will reply “The Lounge is set to low”

  • Asking for Multiple Requests
    Google Assistant does support asking some multiple requests in one question. I.e. if you want to set the heat to 21 degrees, you can ask, “Hey Google, set the heat to 21 in the Lounge”.
    Otherwise you can ask individual questions like “Hey Google, set the Lounge to 21 degrees”, and then “Hey Google, set the Lounge to heat”.

Naming Your Heat Pump in the Wi-Fi Control App

  • Your heat pump will have a name that you originally chose when you set up the Wi-Fi Control App. This name can be found at the top of the Wi-Fi Control App [Control unit] screen if you have one unit, or under [View all units] screen if you have multiple units connected.
  • If you have not renamed your heat pump unit in the Wi-Fi Control App, the default name to use is "Thermostat". (“Hey Google, turn on Thermostat”)
  • If this is the first time downloading and setting up the Wi-Fi Control App you will name your heat pump in the [Edit this unit] screen.

Renaming Your Google Assistant Discovered Heat Pump

  • If you wish to rename your heat pump please do so in the Wi-Fi Control App.
  • Next ask Google Assistant “Hey Google, sync devices”.
  • This will update any changes to device names and/or find new devices.

Important: never rename the heat pump in the Google Home App, as this will cause the two apps naming to be out of sync.

Controlling a Group of Smart Home Devices

  • When naming your heat pump you may want to consider if you intend to control a group of smart devices or the heat pump unit only.
  • i.e. if you want to control all smart devices in a room such as your TV, heat pump and lights with one request to turn on or off, you will need to ensure you create a group in the Google Home App under [Smart Home, Groups] with these devices in it. Then you can simply say “Hey Google, turn on Lounge”.
  • Please ensure each smart device has its own unique name for individual control, as a group and device name cannot be the same.
  • For example in a room with a group named ‘Lounge’ your heat pump should be named more uniquely as ‘Lounge Heat Pump’, ‘Lounge AC’ or ‘Lounge Heater’, so Google Assistant can recognise when you wish to control the heat pump only.
  • Google Assistant looks at a smart group before it looks at a smart device, so if it shares a like name it will ask which one. ie group called 'My Office', Device called 'Office Heat Pump'. Ask “Hey Google, what temperature is the office” and Google Assistant will ask you which one.

Important: if you add a heat pump to a group and then remove that heat pump from the Wi-Fi Control App, after resyncing Google Home you will still need to manually remove the heat pump from your group. (Google Home's resync will not remove the remove heat pump from a group).

How to Resync if You Have Added a New Heat Pump Unit in Your Wi-Fi Control App

  • Ask your Assistant Google Assistant “Hey Google, sync devices”.
  • This will update any changed device names and/or find new devices.

Delete a Heat Pump Unit in Your Wi-Fi Control App

If you delete a heat pump unit from your Wi-Fi Control App you will need to manually remove this from your Google Home Smart Home Devices.
