CAUTION
The RDY2000BN is an advanced controller designed to be installed by professional HVAC technicians. Installation by non-qualified personnel may result in degraded system efficiency, occupant discomfort, or equipment damage.
WARNING
Turn off power to the HVAC equipment before attempting to remove an existing thermostat or install a new thermostat. All work must be performed in accordance with the applicable codes and standards.
Refer to Energy Management System Network Plan for MS/TP installation and configuration parameters.
NOTE: Ensure that the UP arrows embossed
CAUTION
To ensure signal integrity observe MS/TP network wire polarity, reference terminator and shield earth grounded at one location, two end-of-line terminators, and if required an external network bias device. MS/TP devices from some vendors may refer to input A as (-) and input B as (+) or may require external network bias. For RDY2000BN, NETA is non-inverting input A (+) internally biased high, NETB is inverting input B (-) internally biased low to REF (↓), and external bias is not required.
The installation is now complete. Restore power, and continue to Thermostat Setup.

Auxiliary Sequences
The RDY2000BN primary sequences are designed to control single and multi-stage heating/cooling systems to maintain a user-selected temperature setpoint. The following auxiliary sequences are available to optimize occupant comfort and system efficiency:
The humidification relay will energize when measured humidity drops approximately 4% below setpoint and will de-energize when measured humidity reaches setpoint. Deadbands and proof timers are in force to prevent short cycling.
Parameters
Sensors: Onboard humidity sensor or optional remote humidity sensor.
The dehumidification relay will energize when measured humidity rises approximately 4% above setpoint and will de-energize when measured humidity reaches setpoint. Deadbands and proof timers are in force to prevent short cycling.
Economizer Enable
Parameters
Sensors: None required, however an optional occupancy sensor can be used instead of, or in conjunction with the scheduler to determine occupancy.
The Economizer Enable relay will be energized whenever a cooling relay is energized or the space is occupied. The thermostat uses the scheduled Comfort mode to determine if the space is occupied. An optional occupancy sensor can also be used for definitive proof of occupancy. An output configured for Occupancy Notification can also be used for Economizer Enable.
Pre-Purge
Parameters
Sensors: None required.
To enable the economizer and energize the fan relay prior to scheduled occupancy, set P403 to the number of hours before scheduled occupancy for pre-purge to begin. This function requires a schedule to be configured.
Occupancy Notification
Parameters
There are two primary methods by which the thermostat can assume the space is occupied.
The optional occupancy sensor can be used in conjunction with the schedule. The thermostat will follow the assumptions above, but an input from the occupancy sensor during a scheduled unoccupied period will put the thermostat in the Occupied mode for the duration of the timer set in P404. To utilize the Occupancy functions, the thermostat must have an active schedule.
