TEC2102-3 N2 Networked Heat Pump Thermostat Installation Instructions
8
You must not have a Relinquish Default for the
setpoints if you want to change them from the
thermostat display.
If there is a Relinquish Default for the setpoints, the
Network Automation Engine (NAE) always has an
Override for either an adjusted value or the Relinquish
Default Value. You should use Operator Override and
Release Operator Override if you want to command the
setpoint and release it to local control.
Once all the NAE commands are released, the
Override Status in the Hardware tab should be False.
At that time, the user should be able to change the
setpoint from the local display.
All overrides are released automatically after 10
minutes of no communications (for example, network
cable is removed from the TEC, causing loss of
network communications).
