Trane thermostats are groundbreaking devices used to control your room temperature. They are superior to other brands because they have features that make them unique and better advanced. The thermostat controls in Trane are high-tech, and they provide users with an easy-to-use and manage thermostat for temperature control of any room through a Wi-Fi connection. With your smartphone, you can increase or decrease your room temperature- how cool is that! Trane has both programmable and non-programmable thermostats available in various models that accurately control the temperature of your room. These thermostats are efficient in their operations, operate as expected, are durable and reliable, and are ideal for creating the perfect home environment.
Step 1: choosing a thermostat
Trane thermostats come in various models, depending on their use. It can be a single cooling or heating unit, like an air-con or furnace, an electric heating system that has an air-con, or a dual system that incorporates electric elements and has a gas backup. Depending on your needs or budget, the first step is choosing an ideal thermostat for your home. If you have a family that’s constantly at home, you can choose a manual system. But if there are regular periods when no one is at home, a programmable thermostat is ideal for saving energy costs.
Step 2: connecting your thermostat
You need to connect your thermostat wires. This is a simple task, especially if you are changing out another Trane thermostat. You need to mark the wires and then replace them with the new ones, ensuring you place them where you have marked and removed the previous thermostat. But if you are installing from scratch, you need to follow the wires’ colour code. Ensure you correctly match the colours. The red is the power wire from the transformer and connects to the transformer’s R terminal. Yellow is connected to the cooling contactor coil and its other end to the thermostat’s Y terminal. Then, connect the white wire to the relay for the gas valve or electric heat. Connect the green wire to the fan relay and the thermostat’s G terminal. Programmable thermostats often require a common wire, usually the black wire. Connect it to the common side of the transformer’s secondary winding and on the thermostat’s C terminal.
Step 3: further connection
Connect the wires as above, but this time, connect the orange wire to the reversing valve. This connection energizes the valve and puts the heat pump in the primary heat source. Connect the white wire to the heat relay to enable the production of emergency heat, which comes on automatically when needed. The thermostat has a switch for this emergency heat you can use when the heat pump fails.
Step 4: testing
Testing allows you to feel how the thermostat works and let you know whether you have connected the wires correctly. Turn on the breaker and test your unit and ensure you test both heating and cooling functions. However, you need basic electrical knowledge to install a thermostat on your own success and a general understanding of the equipment.
Programming
Trane thermostats allow you to schedule a program to control better the temperature of your room as you desire. You need to program a newly installed thermostat. You can contact a local Trane service provider to program the thermostat for you, or you can do it. First, you need to identify the control pad on your thermostat to find various control functions. You can then manually set your desired temperature level for the different times of the day according to what you feel is convenient.
