TERMINAL CONNECTION CALLOUTS
Select the thermostat faceplate to be locked out restricting
the override range (dictated by the Temperature Override
Range above) and disallowing access to the HVAC Settings
menu. When engaged, you will be directed to set a 4-digit
pin code that can be used to temporarily unlock the faceplate
for 30 minutes.
After a power failure, the thermostat will delay the heating/
cooling equipment start-up by 1-24 seconds. When multiple
NetX™ X-Series thermostats are used, this minimizes the ‘in
rush’ current (electric power usage) as it reduces the number of
HVAC units that will be turned on simultaneously.
This NetX™ thermostat product has default setpoints as
indicated below. Based on energy saving guidelines and
recommendations for residential use, these settings can reduce
heating/cooling expense by as much as 33%.

Temporarily Unlock Faceplate
When the X5N-SM thermostat is locked, you can temporarily
bypass the Lock Screen by entering the 4-digit PIN. To
temporarily unlock the faceplate, follow the steps below.
