A thermostat works by turning your heating or cooling system on and off whenever the room temperature varies a certain number of degrees from the set-point. This variation is the “swing”.
Your system should cycle on about 3 to 6 times per hour.
“Closed” position is when both pins are covered by little black cap.
“Open” position is when only 1 of the pins is covered by little black cap.
4. The jumpers are labeled on the circuit board next to each black cap. Identify the jumper you are looking for (JP3).
5. Pull the jumper cap off the pins and then place it back in the desired position.
6. Now hit the software reset button on the front of the thermostat behind the door. The swing setting will now be changed.
*Actual temperature variation will vary depending on the conditions. As an approximation:
Narrow +\- ¾” F
Wide +\-1 ¼”F
Example: For tightest control, set swing to “Narrow” which is plus or minus 3/4 degrees F. If you set the setpoint at 70 F, the highest it will get to is 70.75 F, the lowest it will get to is 69.25 F On swing setting “Wide” , if setpoint is at 70 with swing of plus or minus 1.25 F. Highest it will go to is 71.25 F and lowest it will go to is 68.75 F.
