Installation The Meri WiFi Thermostat should be mounted in a suitable location. It is recommended to install the thermostat about 5 ft above the floor and in an open area with good air circulation. Do not install in locations that may affect the temperature reading, such as: - Drafty areas or poorly circulated areas. - Near ducts or appliances that blow hot or cold air. - Concealed pipes and chimneys. - Unheated (uncooled) areas such as an outside wall behind the thermostat.
1. Turn OFF power. Important: You MUST shut off the power at the breaker box that controls your heating/cooling system. 2. Test to make sure the power is off. Sometimes there’s some residual power in the thermostat so it could take up to 5 minutes for your old thermostat to turn completely off. 3. Remove your old thermostat. Most thermostats allow you to just pull off the unit from its wall plate.
5. Take a picture of your current wiring setup. Use your smartphone to take a picture of the wiring and connectors with the letters. You will use this as a reference when connecting to the Meri thermostat. 6. Attach the included label stickers to the wires. Wrap the label stickers around the appropriate wires. This will help when connecting them to the Meri thermostat’s connectors. 7. Disconnect the wires and remove the old wall plate.
and use a pen or pencil to mark the screw holes on the wall. Take off the wall plate and use a 7/32” drill bit to create the hole for the wall anchor, then insert the wall anchors. 9. Bring the wires through the Meri wall plate. Bundle the wires together and through the middle hole of the Meri wall plate. Also check to make sure there is enough exposed wiring (at least ¼ inch) for each wire so they can insert into the wall plate connectors easily.
. Connect your R wire(s). Depending on your heating/cooling system you may have an R, Rh, and/or Rc wire(s). The Meri thermostat can accommodate for these three wires but some configurations require a “jumper” to connect the power. The jumper switch is located on the back of the thermostat as shown in the image below.
To determine the switch position, use the follow chart as a guide.
11. Connect the remaining wires. Match your wires to the appropriate connectors on the wall plate. You will be connecting to the same labeled terminals as your old thermostat connections. You may use the images below as a reference according to your heating/cooling system. Note: Your wire colors mary differ from the images shown below.
