Experience full control of your OJ Microline® UWG5® thermostat with our app. Easily manage and customize your thermostat settings to achieve the perfect comfort level while staying informed with all the data you need. The app offers all information and guidance you need for a proper setup, including the GFCI test. • View and set indoor temperatures With the OJ Microline® UWG5® app, you can easily view and adjust the temperatures in all rooms and locations with installed thermostats. This allows you to customize your floor’s temperature to your liking, whether you need to warm up your beach house for the weekend, prepare a guest bedroom for an unexpected visitor, or get your bathroom ready for a relaxing soak after a long day. • View and change your heating schedule Your OJ Microline® UWG5® thermostat has a default schedule function that automatically adjusts heating levels to match your timetable. However, if you need more flexibility, the schedule mode in the app allows you to create your own schedules from blank or edit its predefined graphics. For example, you can fast-forward to the next scheduled temperature change if you're coming home earlier than expected or turn down the heat for a spring-cleaning session with open windows. • Thermostat Zoning You can control the temperature of different rooms, or zones, in your house by installing multiple thermostats or using a central one. From our app, you can set different temperatures for each zone and control them individually or in groups. For example, you might set a higher setpoint for a bathroom used frequently and a lower setpoint for a bedroom occupied only at night. You can also toggle schedules on or off and put the system in standby mode if necessary. • Set your heating system to vacation mode When you go on vacation or business, you can use the OJ Microline® UWG5® app to plan and schedule adjustments to your heating program. This way, you can save money by not heating an empty home and still have a warm welcome when you return. • View your energy usage The app displays energy usage and allows you to monitor your heating system's current and past energy consumption at any time and location. Energy consumption is calculated per room or building and creates comparison. This can help you identify opportunities to save energy and reduce heating costs. The thermostat detects drafts from open windows, and the app informs you. • Enable voice control/Smart Home Integration If you have a smart home system or voice assistant set up, this app will guide you to connect it to your thermostat and enable voice control. Connecting your thermostat to a voice assistant such as Alexa or Google Assistant offer more convenience and another option to control your system beyond the app. Connecting your app to the thermostat is simple: • Bluetooth® – Local access via Bluetooth® makes it simple to connect to your thermostat • WiFi & Cloud connection – Remotely access your thermostat information in our app in the cloud anytime, anywhere with an internet connection Good for installers to know: • Bluetooth® connection – Local access via Bluetooth® eliminates the need for homeowners' WiFi credentials
