Trane Remote Energy Management Thermostat

The Trane Remote Energy Management Thermostat is a general purpose Z-Wave thermostat. It supports heating and cooling as well as programmability. It has an Auto mode which automatically switches between heating and cooling, depending on the temperature. It also has an Energy Saving Mode (ESM) with 2 sets of temperature setpoints for when you are home and away.

The Trane thermostat Device has one command input terminal and 7 status output terminals. The Device's command input accepts a set of commands for configuring the thermostat. The 7 status outputs give the state of the thermostat. The 8 terminals on the thermostat are described below.

messages:

• the messages terminal is an output terminal which outputs messages which are suitable for emailing and text messages. The messages and command terminals work together. The command terminal tells the thermostat Device what to do, and the messages terminal outputs the results of the commands.

command:

• the command input controls the thermostat. It understands the following quoted values: "status", numbers (temperature settings), "normal", "esm", "heat", "cool", "auto", and "off". Each command will be followed by a result on the messages terminal.

• "status" queries the status of the thermostat. After a "status" command, the messages terminal will display something like this:
  "Mode: Heating
Temp: 70F
Setpoints: Heat: 70F Cool: 78F"

• quoted number commands are temperature setpoint commands. The number from a numeric command is assigned to the setpoint of the currently active mode ("HEATING" or "COOLING"). For example, typing "75" when the thermostat is in cooling mode will set the cooling setpoint to 75 and cause the climate control system to cool until the temperature reaches 75 degrees. After setting a setpoint, you will get a status message on the messages terminal.

• "normal" and "esm" put the thermostat into home and away mode. Normal mode is for when you are home, ESM (energy savings mode) is for when you are away. After one of these commands, you will get a message confirming the command, and the "esm" terminal will reflect the ESM mode of the thermostat (on or off).

• "heat", "cool", "auto", and "off" set the operational state of the thermostat. "heat" and "cool" put the climate control system into either heating or cooling mode. "auto" tells the thermostat to heat or cool depending on the temperature. "off" turns both heating and cooling off. After one of these commands, you will get a message on the messages terminal confirming the command, and the "mode" terminal will reflect the mode of the thermostat. The mode can be "HEATING", "COOLING", "AUTO", or "OFF".

state:

• the state terminal reflects the state of the climate control system. States are "COOLING", "HEATING", and "IDLE".

esm:

• the esm terminal says whether the thermostat is in ESM mode (Energy Savings Mode) or not. The esm terminal is either "on" or "off".

mode:

• the mode terminal displays the mode of thermostat. Possible modes are "HEATING", "COOLING", "AUTO", and "OFF".

temp:

• temp is the current temperature as measured by the thermostat.

heat_setpoint:

• the heat_setpoint terminal displays the setpoint used when the thermostat is in the HEATING state.

cool_setpoint:

• the cool_setpoint terminal displays the setpoint used when the thermostat is in the COOLING state.

Installation

Trane thermostat Devices are installed using the ThermostatTraneRemoteEnergyManagement Script. To install a Trane thermostat Device with the name "Trane", a Z-Wave address of 12, and a polling interval of 60 seconds into a system with a single Z-Wave network, use the following Script parameters:

id: "Trane"
address: 12
poll_interval: 60
