Outdoor Reset Control (P07-P10) - Navien NPE-180A Installation Manual

5.4.4 Outdoor Reset Control (P07–P10)
The Outdoor Reset Control feature can be used to enhance energy efficiency while
maintaining optimal heating performance. Outdoor Reset Control automatically
changes the space heating temperature setting based on the outdoor temperature
and the current space heating system application (system load).
To achieve optimal heating performance, configure the following set-points: the
Outdoor Low Temperature, the Outdoor High Temperature, the heating MIN and the
heating MAX Set-point configuration must be based on the ComfortAir
characteristics and installation environment.
Refer to the following examples in the graph to configure the Outdoor Reset Control
feature.
* The graph above is an example of a few possible outdoor reset parameter settings. For more
information about settings, refer to the following information.
* If the Outdoor Reset On (DIP switch #1 OFF) is set and the outdoor temperature sensor is not
connected, or the outdoor temperature sensor value is outside the normal range, the '740' error
message is displayed and the system operates the same way as with the Outdoor Reset OFF (DIP
switch #1 ON) setting.
