Control Temperature Setpoints
Sequence of Operation
The following paragraphs show the sequence of operation for Application 14900.
Control Temperature Setpoints
This application has a number of different room temperature setpoints (ComfortHtgSP,
EconHtgSP, ComfortClgSP, and EconClgSP). The setpoint can be temporarily overridden for a period of time (default is 30 minutes). The application controls using the effective setpoint (EFF STPT). EFF STPT is set to different values depending on its
HVAC Mode (Cooling, Heating, or Neutral), override status, and the time of day.
CoolingSp : Cooling Setpoint
CoolingDB: Cooling Deadband
CoolingDB is divided equally above and below CoolingSp; therefore, (CoolingSp + 1/2
CoolingDB) is the switching on point of the first cooling stage, and (CoolingSp – 1/2
CoolingDB) is the switching off point of the first cooling stage.
HeatingSp: Heating Setpoint
HeatingDB: Heating Deadband
HeatingDB is divided equally above and below HeatingSp; therefore, (HeatingSp – 1/2
HeatingDB) is the switching on point of the first heating stage, and (HeatingSp + 1/2
HeatingDB) is the switching off point of the first heating stage.
StgDifCl: Cooling Inter-stage Differential
(CoolingSp + 1/2 CoolingDB+ StgDifCl) is the switching on point of the second cooling stage, and (CoolingSP – 1/2 CoolingDB+ StgDifCl) is the switching off point of the second cooling stage.
StgDifHt: Heating Inter-stage Differential
(HeatingSp – 1/2 HeatingDB – StgDifHt) is the switching on point of the second heating stage, and (HeatingSp + 1/2 HeatingDB – StgDifHt) is the switching off point of the second heating stage.
CLG SPAN: Cooling SPAN combined ∆T of all stages of cooling,
CLG SPAN is derived from other parameters. For single-stage cooling: CLG SPAN =
CoolingDB; For multi-stage cooling: CLG SPAN = CoolingDB + StgDifCl*n (where represents the number of stages of additional cooling.)
n
HTG SPAN: Heating SPAN combined ∆T of all stages of heating, HTG SPAN is derived from other parameters. For single-stage heating: HTG SPAN = HeatingDB; For multi-stage heating: HTG SPAN = HeatingDB + StgDifHt*n (where number of stages of additional heating.)
n
represents the
CLG SPAN or HTG SPAN indicates how the bias between room temperature and room setpoint could possibly be due to the characteristic of hysteresis control.

Sequence of Operation
Effective Room Temperature
NOTE:
Effective Setpoint does not exist as a BACnet object. The controller determines what the Effective setpoint is by evaluating the value of ModeEff.
If ModeEff is Heating, EffectiveSetpoint is the value of HeatingSp.
If ModeEff is Cooling, EffectiveSetpoint is the value of CoolingSp.
The actual value used by HeatingSp or CoolingSp at any given time is determined by a number of factors. When operating without any external inputs, the thermostat’s schedule will determine the effective operating mode, RM OP MODE.
If RM OP MODE is set to Comfort, then HeatingSp controls ComfortHtgSP and the
CoolingSp controls ComfortClgSP. If RM OP MODE is set to Economy, then
HeatingSp controls EconHtgSP and the CoolingSp controls EconClgSP. If RM OP
MODE is set to Protection, then HeatingSp controls ProtHtgSP and the CoolingSp controls ProtClgSP.
NOTE:
You can override the effective setpoint through the local touchscreen interface or remotely through the BACnet network by commanding Multistate Value 24,
SchedMode. The local override is only effective for the period determined by
HrsOvrRide (default value is 2 hours).
Effective Room Temperature
IndoorTmpEff:
When an external temperature sensor is not installed, IndoorTmpEff is the onboard temperature measuring value.
When an external temperature sensor is installed, IndoorTmpEff can be configured to either use an external measuring value or the average of external and onboard measuring values.
The external temperature sensor can also be a network sensor. In this case, the external temperature sensor does not have to be physically installed.
The RDY2000BN supports controlling to sensor input over the network. For example, you can take one of the universal inputs, characterize it as a voltage input, remove it from service, and expose it to the network as writeable. Then, you can assign the value of another sensor over the network to this input.
If IndoorTmpEff does not read correctly, you can raise or lower it by changing the value of TmpOffset to the appropriate positive or negative value to make IndoorTmpEff read the correct value.
If the external temperature sensor fails, the unit can be manually switched to only use an onboard sensor.
If the onboard sensor fails, the unit stops running.
Siemens Industry, Inc.
Heating/Cooling Switchover
Auto Switchover enables the controller to automatically switch HVAC modes.
If IndoorTempEff > CoolingSp and Heating has turned off and has been off for the length of time set in ChgOvrDly, the controller switches to Cooling mode.
If IndoorTempEff < HeatingSp and Cooling has turned off and has been off for the length of time set in ChgOvrDly, the controller switches to Heating mode.

Sequence of Operation
Staging Control
ChgOvrDB: Change Over Deadband restricts how close CoolingSp and HeatingSp can be set. A minimum deadband (default is 5°F) must to be maintained. To separate the
CoolingSp and HeatingSp, one setpoint change may change the other setpoint to maintain a gap between them.
Staging Control
The RTU is controlled by a hysteresis loop (Step Control). Hysteresis prevents the compressor/heater from frequently switching on and off. When the room temperature reaches the corresponding switching on setpoint of a certain cooling/heating stage, that stage will be turned on. When the room temperature reaches the corresponding switching off setpoint of a certain cooling/heating stage, that stage is turned off.
For example, in Heating mode the thermostat switches the heater on when the temperature drops below A, but does not turn it off until the temperature rises above B, where B is greater than A.
If there is a call to turn on/off multiple stages, an Inter-stage delay will apply between the two stages being turned ON/OFF. For more information, see the
Compressor
Operation
section.
Compressor Operation
When the HVAC Mode is in Cooling mode, the cooling staging logic controls the compressor.
If a compressor has been ON, it will not shut OFF until its minimum ON timer has expired. Likewise, if a compressor has been OFF, it will not turn ON until its minimum
OFF timer has expired.
In addition to the above rules, there is a time-based separation of cooling stages --
Cooling Inter-stage Delay applies to the unit with multiple cooling stages. There is also a time-based separation of heating stages -- Heating Inter-stage Delay which applies to the unit with multiple heating stages.
The following paragraphs explain compressor staging:
If CoolStg = 0, the application does not control COMPRESSOR 1 (Y1).
If CoolStg ≥ 1, the application controls COMPRESSOR 1 (Y1) as follows:
● If IndoorTmpEff is greater than the switching on point of the first cooling stage
(CoolingSp + 1/2 CoolingDB), and the first compressor has been OFF for at least the time set in MIN OFF, COMPRESSOR 1 (Y1) is turned ON.
● If IndoorTmpEff is less than the switching off point of the first cooling stage
(CoolingSp – 1/2 CoolingDB), and the first compressor has been ON for at least the time set in MIN ON, COMPRESSOR 1 (Y1) is turned OFF.
If CoolStg ≤ 1, the application does not control COMPRESSOR 2 (Y2).
If CoolStg = 2, the application controls COMPRESSOR 2 (Y2) as follows:
● If IndoorTmpEff is greater than the switching on point of the second cooling stage
(CoolingSp + 1/2 CoolingDB + StgDifCl), the second compressor has been OFF for at least the time set in MIN OFF, and the Inter-stage Delay timer has expired,
COMPRESSOR 2 (Y2) is turned ON.
● If IndoorTmpEff is less than the switching off point of the second cooling stage
(CoolingSp – 1/2 CoolingDB + StgDifCl), and the second compressor has been ON for at least the time set in MIN ON, COMPRESSOR 2 (Y2) is turned OFF.

ON Mode – The fan relay is energized regardless of whether or not there is a call for heating or cooling, unless the unit is set to Unit Off.
Fan Opr - The fan relay can be set to be energized or not energized upon call for heat using Paramater P105 (HTG FAN). If P105 is set to ELE, the fan relay responds to the call for heat to energize. If P105 is set to gAS, the fan relay will not be energized upon a call for heat; instead the blower motor is energized by the furnace control board. The furnace control board provides fan delay on/off, protection, and provides other control functions as it directly interacts with the ignition/blower sequence.

Auxiliary Sequences
The RDY2000BN primary sequences are designed to control single and multi-stage heating/cooling systems to maintain a user-defined temperature setpoint.
The following auxiliary sequences are available to optimize occupant comfort and system efficiency:
Humidification
If one of the configurable digital outputs is configured for a humidification function, the corresponding relay will close and enable a 24 Vac output signal to be transmitted to the humidification device. Humidification and dehumidification relays, if configured as such, cannot be energized simultaneously.
● The humidification relay (monitored through HmdyOn) will be energized when measured humidity drops approximately 4% below setpoint (HmdySp) and will be de-energized when measured humidity reaches setpoint. Deadbands and proof timers are in force to prevent short cycling. The thermostat controls humidification only in Heating mode.
● You must enter a humidity setpoint (HmdySp). The valid range is 10 to 90%; the default value is 25%. If the humidity drops to 4% below setpoint, a 30-second proof timer engages. If the humidity is still 4% below the setpoint after the proof timer times out, the humidification relay energizes.

2017-01-17
Sequence of Operation
Auxiliary Sequences
● If humidity rises above (setpoint – 4%) before the proof timer times out, the humidification relay does not engage and the proof timer is reset. If the humidity rises to setpoint, a 30-second proof timer engages. If the humidity is still above the setpoint after the proof timer times out, the humidification relay de-energizes.
● If Parameter P320 (IND HMDTY) is set to NO (default) then the humidification relay will not be enabled unless the heating relay is energized. If Parameter P320 is set to YES, then the humidification relay can be energized at any time, regardless of the heating status. The fan relay is not energized by the humidification sequence.
Dehumidification
If one of the configurable digital outputs is configured for a humidification function, the corresponding relay closes and enables a 24 Vac output signal to be transmitted to the dehumidification device. Humidification and dehumidification relays cannot be energized simultaneously.
● 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 enforced to prevent short cycling. The thermostat defaults to control dehumidification in Cooling mode only.
● You must enter a humidity setpoint (HmdySp). The valid range is 10 to 90%; the default value is 50%. If the humidity rises to 4% above setpoint, a 30-second proof timer engages. If the humidity is still 4% above setpoint after the proof timer times out, the dehumidification relay energizes.
● If the humidity drops below (setpoint + 4%) before the proof timer times out, the dehumidification relay does not engage, and the proof timer is reset. If the humidity drops to setpoint, a 30-second proof timer engages. If the humidity is still below setpoint after the proof timer times out, the dehumidification relay de-energizes.
● If Parameter P320 (IND HMDTY) is set to NO (default), the dehumidification relay will not be enabled unless the cooling relay is energized. If Parameter P320 is set to YES, then the dehumidification relay can be energized at any time, regardless of the cooling status. The fan relay is not energized by the dehumidification sequence.

Occupancy Notification
Many internal control sequences rely on occupancy status, for example: room setpoint choice, fan operation, and economizer enable. Occupancy Notification also goes out from a configurable relay to enable external equipment. The space is assumed to be occupied when the schedule mode is set to Comfort. An optional occupancy sensor can also be used for definitive proof of occupancy (manual override to the room temperature setpoint is the evidence that the space is being occupied).
The thermostat uses three methods to determine if the space is occupied: scheduler, manual override, or occupancy sensor.
● To use the Occupancy functions, the thermostat must have an active schedule.
The local scheduler does not have the direct information about occupancy; instead, 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.

Sequence of Operation
Occupancy Notification
● An 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 into Occupied mode for the duration of the timer set in Parameter P404 (OCC MRT) Occupancy
Min run Timer (OccMinRun). If the optional occupancy sensor is used, Parameter
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.
● If the unit does not have an active schedule, or if it has an active schedule set locally with the effective setpoint being overridden by BMS, the thermostat assumes that the space is always occupied.
Economizer Enable
The Economizer Enable relay energizes whenever a cooling relay is energized or the space is occupied. The space is assumed to be occupied when the schedule mode is set to Comfort. 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
Enabling, for example, while working with Siemens POL 220 Series Economizer
Controller.
Economizer Enable relay (if configured) functions as follows:
● Occupied = Relay energized
● Unoccupied and no call for cooling = Relay not energized
● Unoccupied and call for cooling = Relay energized
● Fresh Air icon is activated
Pre-Purge
To enable the economizer and energize the fan relay prior to scheduled occupancy, set Parameter P403 (PRE OC PRG) PreOcpyPrg to the number of hours before scheduled occupancy for pre-purge to begin. This function requires a schedule to be configured.
Three conditions enable this functionality:
● Unit must have an active onboard scheduler.
● One of the outputs must be set to ECONOMIZER ENABLE.
● PRE-OCCUPANCY PURGE parameter must be greater than 0.
The Economizer Enable and fan relays energize at
X
number of hours before the first scheduled occupancy period. (where
X
is the value entered for PRE-OCCUPANCY
PURGE parameter). The Fresh Air and Fan icons are activated. Other icons are activated or deactivated per standard operation.
The pre-purge period stops when the first scheduled occupancy period starts. At that time, everything reverts to normal operation.

Sequence of Operation
Air Quality Management
Semi-Continuous Fan
If Parameter P405 (CONT FAN) is selected in the set-up menu, the fan relay energizes any time the space is occupied as determined by the Scheduler, or input from the occupancy sensor.
Air Quality Management
If measured CO2 exceeds the setpoint (1000 ppm) by 200 ppm, after a proof timer of
60 seconds, or a CO2 concentration still exceeds the setpoint (1000 ppm) by 200 ppm, the Air Quality output relay energizes and the Fresh Air icon activates. The fan relay (G) energizes and the icon displays.
When measured CO2 falls below the setpoint (CO2Setpoint) after a proof timer of 60 seconds has expired, and the appropriate minimum run time has been met, the Air
Quality output relay de-energizes and the fan relay reverts to Normal operation.
The DCV Minimum run time is five minutes; DCV Minimum off time is five minutes.

Sensor Failure Handling
Service and Fault Messages
All of the three counters for the Service UV Lamp, Service Humidifier and Service Air
Filter are tied to the fan running and are based on calendar days.
● Service UV Lamp (SrvcUvLamp):
The UV Lamp counter keeps track of the run time of the fan calendar days since the UV Lamp service reminder was last acknowledged/cleared. The UV Lamp
Service reminder is triggered when the counter reaches the value set in the Service
UV Lamp parameter. The counter is reset while acknowledging/clearing the UV
Lamp service reminder.
● Service Humidifier (SrvcHmdy):
The Humidifier counter keeps track of the run time of the fan calendar days since the Humidifier service reminder was last acknowledged/cleared. The Humidifier service reminder is triggered when the counter reaches the value set in Service
Humidifier parameter. The counter is reset while acknowledging/clearing the
Humidifier service reminder.
● Service Air Filter (SrvcFilter):
The Air Filter counter keeps track of the run time of the fan calendar days since the
Air Filter service reminder was last acknowledged/cleared. The Air Filter service reminder is triggered when the counter reaches the value set in the Service Air
Filter parameter. The counter is reset while acknowledging/clearing the Air Filter service reminder.

● Failure of onboard humidity sensor:
Stop humidity control, and activate SERVICE REQUIRED segment. Help text displays HUM FAIL.
● Failure of external CO2 sensor:
Stop Air Quality control, and activate SERVICE REQUIRED segment. Help text displays SNSR X FAIL.
I/O Test Mode
Certain expert menus, such as the P500 Series and P900 Series, can disrupt the normal operation and force the unit into Test mode, releasing all of the outputs.
Under the P900 Series menu, the outputs can be overridden by I/O test function and no minimum on/off timers are enforced.
After exiting the P500 Series and P900 Series menus, the unit goes back to normal operation from the Test mode, enforcing all minimum off timers first and then restarting all primary and secondary logic.

Overcurrent Protection
Overcurrent Protection
If the sum of the current flowing through all of the relays exceeds 3A, all of the relays will revert to their OFF state and the OverCurrent binary value object will turn ON. The
RDY2000BN will remain in that state for four minutes. After that time, all of the relays that were placed in the OFF state will change to their ON state.
Then, the controller re-evaluates the overcurrent condition:
● If the sum of the current through the relays does not exceed 3A, the RDY2000BN controls normally, and the OverCurrent binary value turns OFF
● If the sum of the current through the relays exceeds 3A again, the process repeats itself, and the OverCurrent binary value turns ON.

BACnet Scheduler
BACnet Scheduler
The thermostat’s Scheduler functionality can be manually configured using the P107
SCHEDULER in the Wizard/Installer menu. This parameter simplifies the task of entering the local schedule using the touchscreen interface for cases where a day’s schedule may be identical to another day’s schedule. The local schedule can be disabled by setting P107 = OFF.
● By setting P107 = 1, all days will contain the same schedule.
● By setting P107 = 2, Monday through Friday will share a schedule and Saturday through Sunday will share another schedule.
● By setting P107 = 3, Monday through Friday will share a schedule, Saturday and
Sunday will each have a unique schedule.
● By setting P107 = 7, all seven days of the week will have individual schedules.
When editing a schedule through the local touchscreen interface, up to six events can be defined per schedule using the Scheduler menu. When editing a schedule over the
BACnet network, the client simply needs to write to the Weekly_Schedule property of
Schedule instance 0, WeeklySchedule_1.
NOTES:
1. When the schedule is edited using the BACnet network, P107 will be set to 7.
2. The local schedule will write to MultistateValue Instance 24, SchedMode.
This object may be overridden using the network to affect a “temporary exception mode”. Valid states include: Comfort (1), Economy (2) and Protection (3). The corresponding setpoints for each mode are set using AnalogValue instance 32,
ComfortClgSP, AnalogValue instance 33, ComfortHtgSP, AnalogValue instance 34,
EconClgSP, AnalogValue instance 35, EconHtgSP, AnalogValue instance 39,
ProtClgSP and AnalogValue instance 40, and ProtHtgSP. Local overrides will occur for a user-defined duration using the thermostat’s touchscreen interface. The local override will impact the effective runtime setpoints AnalogValue 30, HeatingSp and
AnalogValue 31, CoolingSp.
NOTES:
1. If an Occupancy sensor is configured, the Present_Value of the BinaryInput is evaluated after SchedMode’s Priority_Array arbitration, so the effective runtime operating mode MultistateValue 26, RM OP MODE, will ultimately indicate Comfort if the BinaryInput is active; otherwise, the Present_Value of SchedMode will take effect.
2. The RDY2000BN does not support BACnet schedule features such as exception schedules. Tridium Niagara users must set those unsupported parameters to Skip
Write before importing the schedule objects from the unit for editing. After editing, the parameters can be downloaded to the RDY2000BN. If Skip Write is not marked for those unsupported parameters, an error message displays that the writing failed.
