Discreet, accurate and battery-free: the Trane ZZSENSAL0400AA is a wired indoor temperature sensor that lets a Trane control measure the temperature where it really matters. It serves as a remote sensor for a poorly placed thermostat, or as a zone sensor in a ComfortLink II zoning system.

A reliable reading, where you live

Two uses

The first use is as a remote sensor. If your thermostat is installed in a hallway, near a door or in a room that is not representative, the ZZSENSAL0400AA, placed in the main room, gives the control a more accurate reading. The second use is as a zone sensor: connected to the ComfortLink II zone panel, it measures the temperature of a zone and lets the panel adjust the amount of air sent to it.

Compatible controls

The sensor is compatible with the Trane XL1050 (TZON1050AC), XL950 (TZONE950AC), XL850 (TCONT850AC), XL824 (TCONT824AS) and XL624 (TCONT624AS) controls, as well as with the ComfortLink II zone panel.

Accuracy

The ZZSENSAL0400AA measures temperature from 20 to 120 °F (-6.7 to 48.9 °C), with an accuracy of ±0.5 °F at 75 °F. It operates between 5 and 90% relative humidity, non-condensing. This accuracy, within the usual temperature range of a home, allows stable control, with no noticeable swings.

Wired: no batteries, no pairing

The sensor is wired. It has no batteries to replace and does not depend on any wireless link. In new construction, a renovation with the walls open or a planned zoning project, it is the most durable solution. In a finished home where running a cable would be difficult, the ZSENS930AW00MA wireless sensor can be an alternative with certain controls.

A discreet format

At 2.0 in wide, 3.25 in high and 0.6 in deep (51 x 83 x 15 mm), the sensor goes unnoticed on the wall. It has no screen and no buttons: it simply measures.

Who it is for

This sensor suits owners of a compatible Trane control whose thermostat does not read the right temperature, and ComfortLink II zoning projects where each zone needs a reading without needing a screen. For a zone where the occupants want to set their own setpoint, the XL1040 touchscreen zone sensor is a more complete solution.

Wired sensor or wireless sensor

The ZZSENSAL0400AA measures temperature only, with no batteries and no radio link. The wireless ZSENS930AW00MA adds humidity measurement but requires batteries and a control with a Z-Wave bridge. When wiring is possible, the wired sensor remains the simplest long-term solution, especially in a zoning system where several sensors must work together for many years without service.

Installation by AirGreen

Choosing the location

The sensor must read a representative temperature: on an interior wall, at the usual height, away from sunny windows, supply vents, exterior doors and appliances that give off heat. Our technicians choose this location with you.

The installation

The cable is run to the control or the zone panel, the sensor is mounted and connected, then it is configured in the control. We compare its reading with a reference reading and check that the system responds correctly to the demand from the room or zone.

Maintenance

The sensor requires no particular maintenance. Keep it clear: a piece of furniture, a curtain or a lamp placed in front of it will distort the reading.
