This guide covers setup, usage, troubleshooting common issues and FAQs. ### ![](https://info.wondrwall.co.uk/hs-fs/hubfs/image-png-Oct-21-2024-06-43-14-5432-PM.png?width=320&height=354&name=image-png-Oct-21-2024-06-43-14-5432-PM.png) ### **What is the Wondrwall Thermostat?** The Wondrwall Thermostat is a battery-operated smart thermostat that manages your home's heating and cooling systems. It features an LCD screen and physical buttons for manual adjustments, and can be controlled remotely via the Wondrwall app. Once connected to the Wondrwall app, the system intelligently optimises the thermostat's performance by analysing data on occupancy, behavioural patterns, and outdoor temperature while prioritising comfort throughout the day. ### **The Display** ![](https://info.wondrwall.co.uk/hs-fs/hubfs/image-png-Oct-21-2024-06-47-16-7032-PM.png?width=300&height=143&name=image-png-Oct-21-2024-06-47-16-7032-PM.png) The thermostat's display provides essential information about the device's status, including: | **Label** | **Name** | **Description** | | --- | --- | --- | | A | Heat Icon | This indicates that the thermostat is currently set to heating mode and is calling for heat. | | B | Cool Icon | This shows that the thermostat is operating in cooling mode and is attempting to cool. | | C | Low Battery Icon | Alerts the user when the battery power is running low and needs replacement. | | D | Network Connectivity Icon | Appears when the thermostat is not paired with the network or has lost its connection to the current network. | | E | Mode Display | Displays the selected mode and any offset adjustments made. | | F | Schedule Indicator | This signifies that the thermostat is following a pre-programmed schedule. | | G | Temperature Reading/Setpoint | Shows the current temperature and the setpoint for heating or cooling. | ### **Programming Mode** ### **![](https://info.wondrwall.co.uk/hs-fs/hubfs/image-png-Oct-22-2024-02-20-05-6637-PM.png?width=177&height=346&name=image-png-Oct-22-2024-02-20-05-6637-PM.png)** Programming mode lets you directly adjust settings on the thermostat. There are three settings available for adjustment: changing the Operation Modes (indicated as **Mod**), toggling the Remote Relay function (marked as **RM**), and adjusting the temperature offset (**OFS**). 1. Press and hold the **Down (-)** button for 3 seconds to enter programming mode. 2. Use the **Up (+)** or **Down (-)** buttons to navigate through the three settings. 3. After selecting the desired setting, wait a few moments for the thermostat to confirm and enter the chosen mode. The screen will change to indicate this. 4. Continue using the **Up (+)** or **Down (-)** buttons to cycle through the various modes or adjust the offset level, and again, allow a few seconds for the thermostat to save the new settings. **Caution:** Wondrwall does not use the Remote Relay function; enabling it may hinder the heating system's effective operation. If the **RM** indicator appears on the thermostat it should be disabled by this function by following the [instructions provided below](https://info.wondrwall.co.uk/support/the-wondrwall-thermostat#RemoteMode). ### **How to use the Thermostat** Connecting the thermostat to the Wondrwall app enhances its functionality, allowing users to access additional features and control options. You can also choose to operate the thermostat manually if preferred. Below are some essential operations: #### Adjusting the temperature To adjust the temperature, use the **Up (+)** and **Down (-)** buttons to change the target temperature for heating or cooling. #### Switching Modes To switch between Heat mode and Cool mode on the Wondrwall Thermostat, follow these steps: 1. Press and hold the Down (-) button for 3 seconds until the screen shows 'Pro Mod'.  ![](https://info.wondrwall.co.uk/hs-fs/hubfs/image-png-Oct-22-2024-02-15-47-4673-PM.png?width=180&height=89&name=image-png-Oct-22-2024-02-15-47-4673-PM.png) 2. Release the Down (-) button and pause until the screen says 'Pro Set'. 3. Use the Up (+) or Down (-) buttons to switch between the two modes, Heating and Cooling, represented by a flame icon for heating and a snowflake icon for cooling. 4. After selecting the desired mode, wait a few seconds for the thermostat to confirm the change. Once the selection is made, the display will show whether the thermostat is in Heat or Cool mode. **FAQ: Why is my thermostat heating when I turn the temperature down?** If the thermostat is connected to a boiler and is set to Cool mode, lowering the temperature may unintentionally cause the heating to activate instead. This can create a continuous cycle where the temperature does not decrease as expected. Change the mode back to Heat to fix this. ### **How to Pair the Wondrwall Thermostat** Setting up the thermostat for use with the Wondrwall system is simple. Follow these steps to get started: 1. Navigate to the **Devices** section via the **Menu** and press the **add (+)** button in the top right corner. Select **Thermostat** from the list. 2. Remove the back cover of the thermostat and insert 2 AA alkaline batteries if not already present. 3. Press and hold the **Up (+)** button on the thermostat for 10 seconds. The display will show **Joi NET** when it's ready. This step is also detailed in the app. After that, tap **Next** to initiate the search for the thermostat. 4. The app will search for the thermostat, and after a few seconds, the network connection icon will disappear from the display of the thermostat, signalling that the thermostat has successfully paired with the network. 5. Complete the setup by following the instructions on the Wondrwall app. ### **Diagnostics and Troubleshooting** #### **Low Battery** The thermostat is designed for low power consumption, mitigating the need to replace the batteries frequently. However, it will send an alert through the Wondrwall app when the battery level is getting low. ![](https://info.wondrwall.co.uk/hs-fs/hubfs/image-png-Oct-22-2024-12-40-57-0269-PM.png?width=83&height=60&name=image-png-Oct-22-2024-12-40-57-0269-PM.png) Additionally, the thermostat will display a **Low Battery** icon, shown above when the batteries are running low. #### Replacing the batteries The thermostat is powered using 2 AA batteries. To replace the batteries, access the battery compartment by removing the front cover of the device. To do this: 1. Gently grip the top and bottom edges of the thermostat at its centre and squeeze to release the clips. 2. The batteries are integrated into the front cover, as shown in the below video. 3.
