TRANE thermostats: which one really runs your system?

13 TRANE controls, from the XR102 to the ComfortLink II XL1050, plus the zoning panels, the relay panel and the sensors that go with them. Trane’s guides give the systems each control runs; our tool lines them up side by side, backup heat included.

Our short answer

For a single-stage 24 V central heat pump with electric backup, like the RunTru A5HP5, seven controls sold here run both the compressor and the backup: Priority, XL824, XR724, XR103, XR203, XR302 and XR303. The XL850 and the XL1050 do it with the BAY24VRPAC52DC relay panel, the XR102 and XR202 run the compressor only, and a Trane Link system takes the UX360.

04 · Zoning and sensors

The panels and sensors, and what they need

Seven products on this page are not thermostats: they complete a control. Trane says which control each one works with.

ComfortLink II zone panel

ZZONEPNLAC52ZB

Zones 1 to 4, up to 4 motorized dampers per zone (6 VA max per zone).
It needs the XL1050 and a Trane variable-speed indoor unit; on a 24 V system, the BAY24VRPAC52DC relay panel too.
A discharge air temperature sensor is required, at least 20.3 cm (8 in) above the edge of the supply duct.

Trane: guide 18-HD66D1-4 (2017); catalogue 22-8301-37See the product

ComfortLink II Zone Expander

The same panel as the one in the zoning assembly, set for zones 5 to 8 (zone switch down).
Trane requires it beyond 4 zones: the system then goes up to 8 zones.

Trane: catalogue 22-8301-37, CCZO-12; guide 18-HD66D1-4See the product

XL1040 zone sensor

TZON1040AC52ZA

Communicating zone sensor with a 4.3 in colour touchscreen.
It needs the XL1050, software version 5.7 or later.
Schedules are set on the XL1050, not on the XL1040; the zone stays in Auto mode.

Trane: guide 18-HD88D1-1D-EN (2021)See the product

24 V relay panel

BAY24VRPAC52DC

Three wires (D, R, B) from the control to the panel: the XL850 or the XL1050 then runs 24 V equipment.
Standard system: 3 heating and 2 cooling stages. Heat pump: 5 heating stages (2 compressor, 3 auxiliary) and 2 cooling.
Hum, Aux1 and Aux2 dry-contact outputs (18 to 30 VAC, 2 A max); NORM/DUAL switch for dual fuel.

Trane: guide 18-HD68D1-10 (2017)See the product

Outdoor temperature sensor

BAYSEN01ATEMPA

A 10 kΩ thermistor, mounted on the north side, out of direct sun, at least 30.5 cm (12 in) above the normal snow line.
Wire up to 61 m (200 ft), 18 AWG minimum.
With the XL824, the XR724, the XL850, the XL1050 and the zone panel. Not with the XR302 and XR303, which take the BAYSEN30ATEMPAA.

Trane: guide 18-HD61D1-2; guides 18-HD82D1-1E-EN, 18-HD48D1-1C-ENSee the product

Wireless temperature and humidity sensor

ZSENS930AW00MA

Z-Wave sensor on two AAA batteries; up to 4 sensors set the temperature of the conditioned space.
With the XL824, the XL850 and the XL1050 (software 5.4 or later) and the UX360 (SC360 controller, software 1.70 or later).
It is not the Priority’s sensor: Trane gives the Priority the BAYSENSEAW00UAA.

Trane: guide 18-HD83D1-5B-EN (2021); handbook 22-8301-39See the product

Wired indoor sensor

ZZSENSAL0400AA

Temperature only, no humidity sensing; accurate to ±0.5 °F (0.3 °C) at 75 °F (23.9 °C).
Mounted about 1.5 m (5 ft) above the floor, with less than 61 m (200 ft) of cable.
With the XL824, the XR724, the XL850, the UX360, the zone panel and the relay panel’s RS terminal. Not with the XR302 and XR303, which take the ZZSENSAL0300AAA.

05 · Did you know

Three details from Trane’s guides

The XR103 does not need batteries to run: its two AAA cells only keep its memory.

Guide 18-HD55D1-1C-EN (September 2020)

On the Priority, the installer picks the outdoor temperature below which the backup heat may start: from −3.9 to 21.1 °C, with 7.2 °C (45 °F) from the factory.

Installer’s guide CNTR-SVN004A-EN (May 29, 2026)

The BAY24VRPAC52DC relay panel serves the ComfortLink II controls. A Trane Link system uses another panel, the BAC24VRPA252UA.

07 · Questions

What people ask us about TRANE thermostats

Which thermostat for a RunTru E4HL5?

The E4HL5 is a variable-speed heat pump that RunTru runs on 24 V: its “24V Inverter”, wired to the Y1 and Y2 terminals of a standard thermostat (sell sheet 26-7319-02; manual 88-E4HL5001-1B-EN). In our reading, it therefore needs a control that handles two compressor stages: the Priority, XL824, XR724, XR203, XR302 or XR303, or the XL850 and XL1050 with the BAY24VRPAC52DC relay panel. Trane does not list the XR102, XR103 or XR202 for a two-stage heat pump.

Is the Priority ENERGY STAR certified?

No. The ENERGY STAR smart thermostat dataset holds a single Trane-brand thermostat, the XL824, certified since April 12, 2019 for the United States and Canada; the Priority is not in it (checked October 28, 2026).

Does a TRANE thermostat need a common (C) wire?

On the Priority, the XL824, the XR724 and the XR103, yes: Trane requires the 24 V common. The XR202, XR203, XR302 and XR303 run on two AA batteries; on the XR302 and XR303, the 24 V common is needed for a remote sensor. The XR102 runs on two AAA batteries.

My system is Trane Link: which thermostat?

The UX360, sold as a kit with the SC360 system controller. Trane says a Trane Link system must use this thermostat and this controller; they communicate over 4 wires (CAN bus), and no other control on this page connects to it.

Can the XL850 run an ordinary 24 V heat pump?

Yes, with the BAY24VRPAC52DC relay panel. On its own, the XL850 is a ComfortLink II communicating control. With the panel, three wires (D, R, B) are enough and it runs 24 V equipment: up to 5 heating stages on a heat pump (2 compressor, 3 auxiliary), 3 on a standard system.

Are TRANE thermostats right for electric baseboards?

In AirGreen’s view, no. Trane’s guides give these controls a low-voltage input (24 V, or millivolt for the XR102 and XR202), and none of them names electric baseboard heaters. That is our reading, not a Trane statement: baseboards need a 240 V thermostat designed for them.

Is the Pivot right for a home?

No, per Trane: it sells it as a commercial thermostat (“Commercial Applications Only”), for single-zone, constant-volume commercial buildings. It uses the Pivot app, not Trane Home.
