TRANE XR102 thermostat TCONT102AN11AA

In many older homes, the thermostat is connected to the furnace by only two wires. That makes it impossible to power a modern electronic thermostat without running new wiring, unless you choose a model that does not need it. The Trane TCONT102AN11AA is one of those: a non-programmable electronic thermostat that runs on batteries only, with no common wire, for systems with one heating stage and one cooling stage.

The simplicity of a push-button thermostat, the precision of electronics

Who it is for

This thermostat suits homeowners who want to replace an old mechanical thermostat with an accurate electronic model, without programming or complicated settings. It is especially well suited to cottages, rental units, annex rooms heated by a dedicated furnace and any installation where the wiring has no C wire. It will also appeal to people who prefer to set the temperature themselves, as needed, rather than follow a schedule.

Compatible systems

The TCONT102AN11AA controls gas, oil or electric systems with up to 1 heating stage and 1 cooling stage. A furnace on its own, or a furnace paired with a single-stage central air conditioner, falls within these limits. It does not handle heat pumps: for a heat pump, its sibling, the TCONT103AN21MA, is the right model.

No common wire needed

The thermostat is powered by batteries only, which are included, and has no common terminal. It therefore installs on existing two- or three-wire wiring without modification. An RH/RC jumper lets the wiring be adapted depending on whether or not the heating and cooling share the same transformer.

Straightforward to use

It works with push buttons. No menus, no schedule: you raise or lower the setpoint, and the thermostat holds the temperature you asked for. The 1.9 in diagonal screen displays the temperature in Fahrenheit or Celsius, as you prefer. A filter change indicator reminds you to maintain your system.

Accuracy and savings

Compared with a mechanical thermostat, an electronic thermostat measures the temperature more regularly and runs the system at the right time, which reduces temperature differences in the house. Even without programming, you can save during the Quebec winter by getting into the habit of lowering the setpoint in the evening and before leaving for several days. To automate these reductions, a programmable model such as the TCONT202AS11MA would be a better fit.

An easy replacement

The TCONT102AN11AA is a direct replacement for older Trane thermostats, including the THT00583, THT02772 and THT2424. Its dimensions, 3.88 in high, 5.5 in wide and 1.18 in deep, generally cover the footprint of the older models. Its glossy white case blends in with most decors.

Day to day

Set your comfort temperature and let the thermostat do the work. For an extended absence in winter, lower the setpoint without shutting off the heat, to protect the house from freezing. Replace the batteries as soon as the display fades or the indicator calls for it: a thermostat without batteries can no longer control the system.

Cottages and secondary homes

In a cottage or secondary home heated by a furnace, what you want most is a reliable thermostat that is easy to set when you arrive and able to hold a protective temperature while you are away. The TCONT102AN11AA meets these needs: it depends on no network, requires no additional wiring and is set with a few presses. Before leaving for the week, simply lower the setpoint to a level that is safe for the building.

Before you buy

Two checks are enough to confirm that this model is right for you: your system must be a gas, oil or electric furnace, with or without a single-stage air conditioner, and you must be comfortable with manual adjustment. If you have a heat pump, or if you want automatic programming, we will direct you to another model in the lineup.

102 or 103

The TCONT102AN11AA and the TCONT103AN21MA share the same 1.9 in screen, the same buttons and the same format. The 102 runs on batteries and controls single-stage furnaces and air conditioners. The 103 is reserved for heat pumps, with one compressor stage and one backup heat stage, a configurable reversing valve, an emergency heat mode and a keypad lockout; it requires a common wire. Your type of equipment therefore determines the right model.

An understated device

Its compact format and clean display suit entrances, hallways and rooms where you do not want a bright screen on the wall.

Placing the thermostat correctly

An accurate thermostat is a well-placed thermostat: on an interior wall, away from sunny windows, warm-air vents, exterior doors and the kitchen. During a replacement, our technicians check the existing location and advise you if moving it would improve comfort.

Replacement and installation by AirGreen

The installation

Our technicians confirm that your system does have one heating stage and one cooling stage, remove the old thermostat and identify each wire. The TCONT102AN11AA is connected, the RH/RC jumper is set to suit your installation, then heating, cooling and ventilation are tested. We set the display to Celsius or Fahrenheit, as you prefer.

Maintenance

Replace the batteries at least once per heating season or as soon as the display fades. Wipe the case with a dry cloth. Follow the filter indicator and have your furnace and air conditioner serviced every year.
