23°F to 122°F (-5°C to 50°C)

-13°F to 158°F (-25°C to 70°C)

NOTE: The RDY2000 is not battery-powered. It

requires 24 Vac power from the HVAC equipment at terminals RH/RC and C.

Product Number

RDY2000

Required Tools

• No. 1 Phillips screwdriver

• 1/8” flat-blade screwdriver

• Drill with 1/8" drill bit

Expected Installation Time

15 minutes

The RDY2000 is an advanced controller designed to be installed by professional HVAC technicians. Installation by nonqualified personnel may result in degraded system efficiency, occupant discomfort, or equipment damage.

Prerequisites

• All work must be performed in accordance with applicable codes and standards.

• Use 18 gauge thermostat wire for equipment connections.

• 22 gauge shielded cable is recommended for remote sensor wiring. Do not exceed 150 feet.

• To replace an existing thermostat, verify if 24 Vac is present between the RH/RC and C terminals.

• Turn off power to the HVAC equipment before attempting to remove the existing thermostat.

• Record wiring connections to existing thermostat terminals.

• Remove the existing thermostat before proceeding.

Caution Notations

Installation

1. Install the thermostat base plate. a. Feed the existing wires through the opening

in the base plate.

b. Secure the base plate to the mounting

surface using supplied hardware.

Document No. 129-905

Enables adustment of temperature

cooling setpoint if in Cooling mode.

Enables fan relay to be controlled to be on continuously (ON).

Enables manual changeover

control functions.

Enables Scheduler, Time/Date, and

and fault messages.

Installation Instructions March 26, 2015

NOTE: Ensure that the UP ar ro ws embossed

on the base plate are pointed upward.

Figure 2. Thermostat Base Plate.

NOTE:

If 24 Vac was verified as being present at the thermostat wires (see Prerequisites), sk ip Step 2 and proceed to Step 3.

2. If 24 Vac is not present at the thermostat: a. Locate the 24 Vac transformer or 24 Vac on

the terminal strip on the HVAC unit. Attach a thermostat wire to the 24 Vac source. See the HVAC equipment schematics to verify the correct terminals.

b. Attach the other end of the unused wire to

the thermostat RH or RC terminal.

c. Verify that 24 Vac is present between the

RH/RC and C terminals.

3. Attach the existing wires to the appropriate

terminals on the thermostat base plate. See Wiring Diagrams, Figure 4 and Figure 5.

Optional: If using Auxiliary Inputs 1 to 4 or configurable outputs 1 to 3, use setup parameters P301 to P320 to set functionality.

4. For systems with dual transformers, do the

following; otherwise, proceed to Step 5:

If separate transformers are used for heating and cooling systems, connect 24 Vac from the cooling system to RC, and 24 Vac from the heating system to RH. Remove Jumper RHRC.

Optional: Auxiliary Output 3 can be changed to a dry (unpowered) contact by removing Jumper RC-C3 See Wiring Diagrams, Figure 6.

5. Attach thermostat to the base plate by engagi ng

tabs at the top and rotating the thermostat downward until it is securely seated on the base plate.

6. Secure the thermostat to the base plate with the Phillips screws (provided), using the holes at the bottom of the housing.

The installation is now complete. Restore power, and continue to Thermostat Setup.

Auxiliary Sequences

The RDY2000 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 energ i zed independently of heating and cooling relays.

Page 14 of 18 Siemens Industry, Inc.

• Humidity Setpoint: User adjustable to desired level in humidification mode.

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.

March 26, 2015

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 relays.

• Dehumidity Setpoint: User adjustable to desired level in dehumidification mode.

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 will use the scheduled setpoints to predict when s pace is occ upie d. An opt ion al 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.

1. In Cooling mode, it will assume that scheduled

periods with lower setpoint(s) indicate occupancy. In Heating mode, it will assume occupancy during periods of higher setpoints.

2. During periods in which the schedule indicates

the space is unoccupied, any human interaction with the thermostat (for example, setpoint adjustment) will put the therm ostat 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 thermos tat 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, 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-energ i zed an d the fan relay shall revert to normal operation.
