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.
- Refer to the network plan for MS/TP wire color code used for (+), (-), and (↓).
- See Figure 7 for wiring the thermostat at the middle of line (two MS/TP cables) or at the end of line (one MS/TP cable).
- If the thermostat at the middle of line, connect terminals to two MS/TP cables with (+) to NETA, (-) to NETB, and (↓) to Connect shield wires together and insulate.
- If the thermostat at the end of line, connect terminals to one MS/TP cable and one end-of-line terminator with (+) and terminator to NETA, (-) and terminator to NETB, and (↓) to REF. Verify shield is connected to the earth’s ground and insulated.
- Attach the thermostat to the base plate by engaging tabs at the top and rotating the thermostat downward until securely seated on the base plate.
- Secure the thermostat to the base plate with the Phillips screws (provided), using the holes at the bottom of the housing.
- Remove the thermostat LCD screen cover.

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:
Humidification
Parameters
- P317/ P318/P319: One of these must be set to 1
- P320: NO (default) = Humidification will only occur if there is a call for heating. YES = Humidification relay will be energized independently of heating and cooling
- Humidity Setpoint: User adjustable to desired level in humidification
- Sensors: Onboard humidity sensor or optional remote humidity sensor.
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.
Dehumidification
Parameters
- p317/ P318/P319: One of these must be set to 2
- P320: NO (default) = Dehumidification will only occur if there is a call for cooling. YES = Dehumidification relay will be energized independently of heating and cooling
- Dehumidity Setpoint: User adjustable to desired level in dehumidification
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
- P317/P318/P319: One of these must be set to 5.
- P301/P305/P309/P313: One of these must be set to 8 if the optional occupancy sensor is used.
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
- P317/P318/P319: One of these must be set to 5.
- P403
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
- P301/P305/P309/P313: If the optional occupancy sensor is used, one of these must be set to 8.
- P317/P318/P319: To signal an external device that the space is occupied, one of these must be set to 3
- P404: If the optional occupancy sensor is used, P404 can be used to set a minimum run timer for any actions that are activated by occupancy, such as Economizer Enable, control to occupied temperature setpoints, and so on. Note that many occupancy sensors also have onboard proof timers.
There are two primary methods by which the thermostat can assume the space is occupied.
- The space is assumed to be occupied when the schedule mode is set to Comfort.
- During periods in which the schedule indicates the space is unoccupied, any human interaction with the thermostat (for example, setpoint adjustment) will put the thermostat into Occupied mode.
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.
Air Quality Management
Parameters
- P301/P305/P309/P313: One of these must be set to 7.
- P317/P318/P319: One of these must be set to 4.
- P402: CO2 Setpoint Sensors: Optional CO2 Sensor
- If measured CO2 exceeds setpoint by 200 PPM for a minimum of 60 seconds, the Air Quality output and fan relays will be energized. The minimum run time is 5 minutes.
- When measured CO2 falls below setpoint and appropriate minimum run time has been met, the Air Quality output relay will be de-energized and the fan relay shall revert to normal operation.
