Away:
When you press the AWAY button - our server sends a message to the thermostat to go to a predefined temperature and then presses hold. You would use this feature if you are leaving the house for a period of time - but not exactly sure when you are coming back. Upon returning, you would resume the HOME mode. This will return the thermostat back to normal operation, running your program, with the hold released.
Holiday: The Holiday Program with a WiFi module is a ONE day program that you can choose to run if you were to have an exception to your program.
This is a good feature to use if you are going to have a different schedule for a given day. The Holiday program is ideal to run for ONE day when you just need a temporary program change. The WiFi module will then return you back to the original program after ONE day. If you are using the WiFi module, many users might find it more flexible to just set up a second (or third) schedule on the website and flip back and forth between schedule as needed using the website. WITHOUT the WiFi module the holiday program will run until shut off.
Mode:
HEAT: The mode where your heater will turn on when your target temperature is ABOVE the room temperature. COOL: The mode where your air conditioner will turn on when your target is BELOW the room temperature.
Auto: Automatically switches between the thermostats heat and cool programs appropriately:
Allows the freedom of setting any heat or cool program targets, regardless of mode, desired temperatures or desired time periods Auto is ideal for times when there are large temperature changes during the day, such as during the Spring and Fall seasons. At 3 degrees F ABOVE the HEAT target, the thermostat switches to COOL mode, however cool will not come on until the cool target is reached. Once reached the AC will come on and maintain that temperature. At 3 degrees F BELOW the COOL target, thermostat switches to HEAT mode. However, since the heat target is still below this temperature the heat will not come on until the target is reached. HEAT and COOL may also be set at the same target temperature.
At 3 degrees F above HEAT the COOL mode will be activated, and since the cool target is at or below this point, cool immediately turns on. The same remains true for 3 degrees below COOL; HEAT will be activated and immediately turned on because its target is at or above the current temperature.
Temporary Override: Temporary is a non-permanent change to the programmed target temperature:
If you are in temporary and you change the target, the target will be restored at the next program time boundary. If you don’t want the temperature to change at the next time boundary - press the HOLD button to keep this constant target.
Hold Button: Hold is used to keep the target temperature constant.
Hold is independent of the program temperature, and the target temperature will not change, unless you manually change it. The thermostat will remain on the held target temperature unless you return to the manual screen and deselect hold.
Fan Button: The Fan has two states ON or AUTO.
ON fan indicates the fan is continuously running.
AUTO fan means that your furnace will be turned on by the thermostat or furnace when there is a call for heat or cool.
Save Energy Button: The SAVE ENERGY button is a one touch button that will apply a 4 degree offset to your target temperature.
If you are heating and the target is 74, when you press the Save Energy button the target will go to 70. This offset will apply across all program periods. Save Energy is useful when you will be gone for a short period of time.
Swing: Swing is the difference between target and room temperature before the heat or cool will turn on.
In heat - if you set the Swing to be 1 degree with a target temperature of 68 - the heat will turn on when the room temperature reaches 67. The heat will then always turn off when it reaches the target of 68. The higher the SWING value, the longer it will take your system to turn on. Ideally, swing is the function used to control how often your heat will turn on depending on the amount of temperature fluctuation you allow.
Differential: Differential is the difference between room temperature and target temperature where a second stage will turn on in a furnace or compressor with multiple stages.
Stages: Some furnaces and compressors allow the thermostat to control the level of heating or cooling. A furnace might have 1 burner running in the 1st stage and 2 burners running in the second.
This will help control how quickly your house will heat or cool. Auxilary Heat, or AUX, is often
considered the second stage for heat
pumps.
C Wire: The “C” or “COMMON” wire is a dedicated wire to run power to the thermostat.
Every 24VAC furnace has a transformer that converts Line voltage (110V) to 24V that is use for the operation of furnace and control by the thermostat. The C wire is connected to one end of that transformer. The C wire is necessary to establish the WiFi connections with your home network. Without a constant supply of power the WiFi would drain the batteries too quickly.
