NO IAQ EQUIPMENT OR ECONOMIZER CONTROL

For any of the 2-4 zone applications listed in this document that do not need to control a Humidifier, Dehumidifier, Ventilator, economizer, or Remote Indoor Sensor, you can eliminate the THM5421R1021. You can either enroll the Prestige IAQ thermostat to the THM4000R1000 wireless adapter that is included in the YTH6320R1023 kit or use another TH6320R1004 thermostat for zone 1 in place of the Prestige IAQ. When a TAZ-4H is used for systems over 4 zones, you cannot use a THM4000R1000.

See Fig. 3 below for basic wiring.

1. EIMS AND ADAPTORS NEED TO BE AT LEAST 2 FEET APART FROM EACH OTHER.
2. THE SUPPLY AND RETURN SENSORS INCLUDED IN THE YTHX9421 2.0 PRESTIGE IAQ KITS ARE NOT USED IN ZONING APPLICATIONS. THE THERMOSTATS CANNOT BE SET FOR DELTA-T DIAGNOSTICS WHEN USED IN ZONING APPLICATIONS.
3. PRESTIGE IAQ THERMOSTATS USED WITH A THM4000R ADAPTOR AND THM6000R GATEWAY LOSE THE 2.0 FUNCTIONALITY ONLINE. THIS MEANS YOU WILL BE ABLE TO OVERRIDE THE SET POINT BUT CANNOT PROGRAM THEM OR CONTROL THE FAN SETTING VIA APP. ALSO THEY CANNOT BE USED IN A DEMAND RESPONSE UTILITY PROGRAM. ALSO YOU CANNOT USE THOSE THERMOSTATS WITH AN R EM1000R1003 EXIT/ENTRY CONTROL OR WSK 24 REMOTE SETBACK.

ALL PRESTIGE THERMOSTATS WITHOUT IAQ CONTROL

Option E: 2–3 Zones (If C7189R or C7189U Indoor Sensors are Used, Cannot Use THM4000R. Need separate EIM for Each Stat).

RedLINK VisionPRO instead of Prestige

For any of the A–F applications listed, you could replace the Prestige IAQ thermostats with TH8321R1001 RedLINK VisionPRO models. When the RedLINK VisionPRO models are used, you can link to the THM5421R1021 or THM4000R1000 (same as Prestige) or wire directly from the thermostat sub-base to the zone connection on the zone panel if wires are available.

See Fig. 5 below for basic wiring.

No IAQ Equipment

Any of the above listed 2-4 zone applications that do not need to control a Humidifier, Dehumidifier, Ventilator, Economizer or Remote Indoor Sensor can eliminate the THM5421R1021. You can enroll all Prestige IAQ or RedLINK VisionPRO thermostats to the THM4000R1000 wireless adapter. When a TAZ-4H is used for systems over 4 zone you cannot use a THM4000R1000.

See Fig. 6 below for basic wiring

1. THE SUBBASE OF EACH THX9421R5021 THERMOSTAT NEEDS TO BE WIRED TO A 24 VOLT TRANSFORMER. THIS CAN EITHER BE THE TRANSFORMER THAT POWERS THE ZONE PANEL OR A SEPARATE TRANSFORMER.
2. EIMS AND ADAPTORS NEED TO BE AT LEAST 2 FEET APART FROM EACH OTHER.
3. THE SUPPLY AND RETURN SENSORS INCLUDED IN THE YTHX9421 2.0 PRESTIGE IAQ KITS ARE NOT USED IN ZONING APPLICATIONS. THE THERMOSTATS CANNOT BE SET FOR DELTA-T DIAGNOSTICS WHEN USED IN ZONING APPLICATIONS.
4. PRESTIGE IAQ THERMOSTATS USED WITH A THM4000R ADAPTOR AND THM6000R GATEWAY LOSE THE 2.0 FUNCTIONALITY ONLINE. THIS MEANS YOU WILL BE ABLE TO OVERRIDE THE SET POINT BUT CANNOT PROGRAM THEM OR CONTROL THE FAN SETTING VIA APP. ALSO THEY CANNOT BE USED IN A DEMAND RESPONSE UTILITY PROGRAM. ALSO YOU CANNOT USE THOSE THERMOSTATS WITH AN REM1000R1003 EXIT/ENTRY CONTROL OR WSK 24 REMOTE SETBACK.
