A faulty digital thermostat can mean very cold winter nights and sticky sweaty summer days. That is why it is important to have a basic knowledge of Emerson thermostat troubleshooting to maintain the right temperature for your needs.
First, we must understand how to program an Emerson Thermostat.
How to Program an Emerson Thermostat
A thermostat manual will outline how to program each type of thermostat and should be consulted to find out user-adjustable options. To access the model number, remove the front panel and look behind it. Then use that to download the appropriate thermostat manual from the Emerson website.
Generally, though, you have to set the time and date first, followed by the heating or cooling schedule. Most Emerson thermostats come with a factory default schedule which is advisable to use. Keep a copy of the manual handy for Emerson thermostat troubleshooting when needed.
How to Reset an Emerson Thermostat?
Most Emerson thermostats have the same operational procedures. To reset the thermostat to factory defaults, press both the up and down arrows and the time button all at the same time. This removes all changes and puts it back to its unboxed state. The procedure can also be used any time an Emerson Thermostat is not working.
What Does It Mean When the Thermostat Is Blinking Red Light?
Just like a red light in traffic, any red light on the thermostat is a sign of trouble and should be attended to immediately. Try the procedures below until one resolves the issue or you have to call a thermostat specialist (HVAC technician):
- Turn the unit off and wait 5 minutes before restarting it.
- After the unit is back on, wait for the outdoor unit to start running. This should take about 10 minutes. Thereafter check to see if the red light is no longer blinking.
- Some causes of such failure are blocked air filters or coils, a faulty fan motor, or a faulty pressure switch. All these require the attention of a thermostat specialist.
Why the Snowflake Is Blinking on Your Thermostat
A blinking snowflake light means the thermostat is in the cooling cycle but on standby since the required temperature has been reached.
This is a protective measure for the system not to overworking itself and damage the compressor, fan or other critical cooling system parts.
Why Does My Thermostat Say Emergency Heat?
As the name suggests Emergency Heat setting is only to be used in case of an emergency such as when the main heat pump is not functioning or if it freezes over due to colder than usual weather. The main heat pump is usually a part of the outdoor unit rendering it vulnerable to freezing.
Wiring an Emerson Thermostat
Tools and Equipment needed to include:
- Small Phillips or Flat-head screwdriver
- Small pliers (needle-nose)
- Drill with 3/16” (4 mm) bit Optional:
- Wire cutters/stripper
- Hammer (for wall anchors)
Once you have gathered this equipment, follow the steps outlined here:
- Turn off power to the old Thermostat or disconnect power from the mains supply.
- Remove the old thermostat cover and move to the next step.
- Label wires that supply power to your thermostat. If this is a new installation, follow the Emerson thermostat model-specific manual to carry out the correct wiring. Improper wiring may lead to high power bills or damage your thermostat. Ensure an old thermostat’s mercury tube is disposed of properly.
- Connect wires according to the labels you created. If it is a new installation, connect according to the owner’s manual.
- Insert the batteries properly and attach the thermostat cover.
- Configure the thermostat according to the owner’s manual supplied with it. Usually, this involves setting the correct date and time, then selecting a cooling or heating default setting. However, you can adjust the temperature control pattern according to the prevailing environment.
- Turn on the power and observe thermostat operation. If it heats or cools according to your requirement then you have successfully installed the Emerson thermostat.
Changing Batteries in an Emerson Thermostat
Changing the batteries is fairly easy and needs to be done after a fairly long time. Some thermostats require battery change only once a year. Follow the steps below to change the battery:
- Remove the mounting from the wall or remove the front cover depending on the Emerson thermostat model you have.
- Find the worn-out batteries and remove them. You may use a small screwdriver to pry them out.
- Install the new batteries correctly according to the instructions on the battery compartment. Improperly installed batteries may damage the thermostat.
- Reattach the front cover or remount the thermostat to the wall. Once more, this step depends on the type of thermostat, so just do a reverse of what was done in step one.
- Batteries help to keep your programmed thermostat settings when power is lost. They should be changed when the thermostat displays a low battery sign.
How to Get an Emerson Thermostat out of Lock Mode
Keypad lockout mode is a setting that is used to prevent unauthorized settings changes on the thermostat. To unlock an Emerson thermostat, follow the steps below:
- Select Settings
- Select Keypad Lockout.
- Select Off
- Enter the authorization key
- The same steps apply even when accessing the thermostat from a smartphone via Wi-Fi.
How to Connect Your Thermostat to WI-Fi
Connecting your thermostat to Wi-Fi will depend on the phone type you have and the thermostat model you have. Generally, it should follow the steps below with minor differences that you can figure out as you go along.
To connect your Emerson thermostat to Wi-Fi, follow these steps:
- Download the Emerson app for your specific device and open it.
- Select the + sign.
- Select “Yes, it is on the wall”
- Select “Menu” and then “Connect”. An option to select the network appears. Connect to the appropriate network. You may select the “scan again” option if the network does not appear.
- After connecting, use the product-specific code found on the packaging to connect to the network. This code may also be found at the back of the thermostat unit.
- Next, select your home Wi-Fi network and enter the password for it.
- You can now configure the Emerson thermostat remotely, save settings and record temperature usage.
Emerson thermostats have greatly kept up with technological improvements to make it easier for you to enjoy the right temperature at the right time. To get the most out of it, ensure that you keep the Emerson product owner’s manual for satisfactory operation of the system.
All digital Emerson thermostats can connect to your home Wi-Fi for even easier configuration and handling. Additionally, this makes Emerson thermostat troubleshooting much easier since the interface is the very familiar one on a smartphone application.
