Random Restart
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™ X-Series has an internal power backup that will last approximately two days. If the thermostat experiences a power outage less than this time, all functions will resume as soon as power is restored. If the power outage lasts longer, upon power restoration the X-Series thermostat will recover depending on a few factors.
REMOTE SENSORS (OPTIONAL)
If your NetX™ thermostat has been installed with one or more NetX™ remote sensors, the sensor information is available onthe small secondary display of the thermostat. There are many different remote sensor options. You can view the remote sensor information by tapping the upper left part of the display to view different attached remote sensors.
RS1 – RS2 – RS+V: Remote Sensor Bus
Used for connection of a wide variety of NetX™ remote sensors, allowing installation flexibility and additional information from the communications bus. It also allows the thermostat to be placed in an area away from view.
Remote Sensor Averaging
If remote temperature sensors are connected, the X-Series thermostat can either use the remote sensors (default) or average the remote sensor and the internal temperature sensor. The Remote Sensor Averaging setting can be accessed from the HVAC Settings web page of the thermostat.
A NOTE: If no remote sensors are detected, the thermostat will default to the internal temperature sensor regardless of the selected option.
On-board Data Logging with Sub-Metering Support
The NetX Platform provides reliable deep-data analysis for runtimes and all thermostat operations. This data can be used to perform sub-metering analysis to bill tenants according to actual HVAC usage for heating and cooling. Onboard memory supports approximately 30 days of records.
PROGRAMMING THE THERMOSTAT
This NetX™ thermostat product has factory default programs as indicated below. Based on energy-saving guidelines and recommendations for residential use, these settings can reduce heating/cooling expenses by as much as 33%
This thermostat is intended to be used as a Communicating Programmable Thermostat, with changes to the thermostat schedules accomplished over a computer interface via:
