Removing the existing Thermostat
If you are removing an existing thermostat it is important to pay close attention to the
wiring in place and to label each connection as you remove it from the existing
thermostat. This will help in making the correct connections to the NT20e. Here are the
steps that will ensure a proper removal:
1. Follow these steps to ensure proper removal of the existing thermostat:
2. Turn off power at the HVAC system or the fuse/circuit breaker panel.
3. Remove the cover from the existing thermostat. If the cover does not snap off
when pulled firmly from the top or bottom, check for a screw or screws that
may be used to lock on the cover.
4. Label the wires one at a time placing the label about 1/2” away from the end
of the wire to allow stripping of the ends.
5. As you disconnect each wire, label it with the terminal designation from the
existing thermostat. Make sure the wires do not fall back inside the wall. If this
is a new installation the wire designations can be obtained from the HVAC
installer.
6.
Once all wires are labeled, remove the existing thermostat from the wall.
