Google Nest Learning Thermostat Installation Guide Overview

Summary of Contents

• Page 1: Learning thermostat installation guide
• Page 2: The Nest Learning Thermostat for the UK and Ireland should be installed by a professional. A Nest Pro will ensure that your heating system is working and conforms to building and safety regulations. The Pro will find the best place to install your Nest Thermostat. They will install the thermostat and Heat Link. The Pro will connect your thermostat to Wi-Fi or assist you in doing it yourself. You will receive a quick product introduction and demo. If installation has already been purchased, it can be scheduled with your reseller. More information can be found at the provided website.
• Page 3: Compatibility In the box Before you start Installing the Heat Link Installing the thermostat on the wall Installing the thermostat on the stand Wiring diagrams ErP class Nest Labs (Europe) Ltd. Limited Warranty WARNING: High voltage. The Nest Thermostat should be installed by a professional.
• Page 4: Compatibility The Nest Learning Thermostat is compatible with almost all central heating systems, including combi boilers, system boilers with hot water control, heat pumps (heating only), zoned systems, and district heating with electrical control valve. A Wi-Fi connection is required to control the Nest Thermostat with the Nest app and to receive software updates. Control systems include On/Off and OpenTherm.

• Page 6: Before you start You may want to install the Nest Thermostat somewhere new. Where should you install it? Place it within 30 metres of the Heat Link. Closer is generally better. The Nest Thermostat should be in a room that’s used often so that it can read the right temperature. If the current thermostat isn’t in a good location, install the Nest Thermostat in a new place with the Nest Stand. It should have a clear view of the room. Wall-mounted thermostats should be installed on an interior wall. Make sure that it’s away from draughts and heat sources. For zoned systems, install the thermostat in the zone that it’s controlling.
• Page 7: Installing the Heat Link is important before the Nest Thermostat. Do not connect the thermostat directly to your heating system. High voltage current can irreparably damage the Nest Thermostat. The Heat Link is necessary, even if there are low-voltage wires.
• Page 8: Installing the Heat Link requires switching off mains power. Protect yourself, the heating system, and the thermostat by turning off the power before starting. High voltage wires are present.
• Page 9: Connect to power and the control circuit. Check the heating system’s wiring to determine its type. Remove the Heat Link cover and connect the L (live) and N (neutral) terminals on the Heat Link to the L and N circuit on the boiler or junction box. This will power the Heat Link. Connect the heating control circuit to the Heat Link as needed. If the system has a hot water control circuit, connect it accordingly. If you have an OpenTherm boiler, connect its control circuit to the OT1 and OT2 terminals. See pages 20-25 for detailed wiring diagrams.
• Page 10: Installing the Heat Link Connect to the thermostat wires. Take two wires from the wire bundle that goes to the current thermostat and attach them to the T1 and T2 terminals on the Heat Link. 12 V DC power. Earth. OpenTherm (42 V DC max). Call-for-heat (normally open). Common. Satisfied (normally closed). 230 V AC live and neutral input power.
• Page 11: Mount the Heat Link near the boiler or junction box. Use the screws included for installation. Ensure a good wireless connection to the thermostat by leaving at least 30 cm of space on each side. Install the Heat Link within 30 m of the thermostat.
• Page 12: Installing the thermostat involves two methods: on the wall or using the stand. Choose the wall installation if the current thermostat connects to heating wires in the wall and doesn’t need to move. Choose the stand installation if you’re replacing a wireless thermostat or if the thermostat needs to be moved to a better position. The Nest Stand is sold separately. You can place the thermostat on a desk, shelf, or other flat surface. For more information, visit the specified website. Refer to page 13 to start wall installation. Refer to page 14 to start stand installation. Existing thermostat wires are used in the wall installation method.
• Page 13: Install the Nest base. Remove the old thermostat if there is one. You can attach the Nest base directly to the wall or use the trim plate included to cover up any marks. Connect the wires coming through the wall to Nest’s T1 and T2 terminals. It doesn’t matter which wire goes into which connector. If you’re using the trim plate, snap it onto the base first, then screw them to the wall as one piece. When installed on the wall, the Nest Thermostat should be 1.2-1.5 m above the floor. Terminate and insulate all wires according to the regulations in your country or region.
• Page 14: Install the Nest Stand. Make sure that you install the Heat Link before you install the Nest Thermostat. Attach the thermostat base to the stand according to the instructions that came with it. Connect the power cable to the base and plug it into a wall socket. Stand-mounted thermostats should be placed on a table or shelf 0.75–1 m above the floor and no further than 1 m from the edge. The Nest Stand is sold separately and comes with its own installation instructions.
• Page 15: Finishing installation and setup Attach the display Press the thermostat display onto the base until it clicks into place. Switch on mains power and the Nest Thermostat will begin setup.
• Page 16: Finishing installation and setup Setup Control it with the Nest app The Nest Thermostat will turn on and take you through setup. You can select a language, connect it to Wi-Fi, and tell it some things about your home and system so that it can help save energy. To control your thermostat with your mobile, download the free Nest app from Google Play or the iTunes App Store. Then create a free Nest account with the app. The Nest Thermostat doesn’t have a touch screen. Turn the thermostat display and press it to select. You can go to home.nest.com if you’re using a computer. If you need help, please visit nest.com/eu/pairing
• Page 17: Getting started Using your thermostat Your thermostat can automatically start learning your schedule or you can choose a schedule with preset times and temperatures. You can edit your schedule at any time. For help with getting started, learning about Nest Thermostat features, energy-saving tips and more, please go to nest.com/eu/thermostatbasics
