Radio Thermostat CT30 Control4 Driver License

Partner: HouseLogix
HouseLogix has created a direct WiFi Control4 driver for the Radio Thermostat CT30 and Filtrete 3M-50. Now this low cost 802.11 wireless thermostat can be integrated with the highly powerful Control4 automation system. Best of all, no Internet connection is required since our driver talks directly to the thermostat over the network (for best results we recommend configuring the thermostat with a fixed IP address).

Our Control4 driver allows you to add the CT30 WiFi Radio Thermostat to your project and control it like you would any other thermostat. We've mapped out the following features:

  • Remote Temperature Support
    • Instead of using the local thermostat's sensor, you can set the temperature to ANY Control4 variable in the project. That means you can use another device like a motion sensor, different thermostat, or wireless contact sensor as the basis.
  • Set the schedule using the Control4 interface (touch panels, MyHome PC, and TV interface)
  • Property windows showing the thermostat model and firmware version.
  • Thermostat LED control
  • Send numbers to the Price Message Area of the LCD
  • Reboot the thermostat from programming or within Composer.
  • Adjust heating and cooling temperature set points
    • In heat and cool mode only, there is a known bug on the thermostat preventing set point modification in auto mode
  • Set system mode to heat, cool, auto or off
  • Change fan mode to Auto or On
  • Set the Hold mode (*see dealer notes below)
  • View the current temperature
  • View HVAC state
  • View Fan state
  • Change the temperature scale from Fahrenheit to Celsius
  • All standard Control4 thermostat variables that map to the CT30 functionality are available.

Dealer Notes:

  • The Wi-Fi module requires power from the furnace "Common" line, or an external transformer in order to run.
  • Choosing "Remove Hold" in Control4 will set the CT30 "End Away" status.
  • All interaction with the CT30 WiFi Thermostat is done directly over WiFi.
  • The driver properties must be entered and set in the order in which they are listed in the Composer Properties window.

* Disclaimer: Please note that this driver is in no way directly supported or endorsed by RADIO THERMOSTAT COMPANY OF AMERICA.

CT30 WiFi Thermostat
Driver Version: [v2.1]

Online Documentation:
Technical Support Site:


Control4 integration driver for the CT30 WiFi Thermostat. Once the Thermostat IP Address is populated,
the current status is retrieved.

Dealer Notes:
* All interaction with the thermostat is done directly over WiFi.
* The license activation process starts immediately after setting the License Key property.
* All driver features are disabled until the driver is activated.
* The driver properties must be entered and set in the order in which they are listed.

Scheduling Notes:
When you press the Save button in Navigator, the change may not show immediately. The new schedule is sent
to the thermostat, which must process it first, before returning the new schedule. This process can take several
seconds to complete.

It is recommended that you use either the physical thermostat to setup scheduling, or this driver
to setup scheduling, but not both. Conflicts could occur. Control4 only allows a single schedule for
both Heat and Cool setpoints, whereas the Radio Thermostat products have a seperate schedule for Heat, and
a seperate schedule for Cool. If you use this driver to manage your scheduling, it will push the same schedule
to both the Cool and Heat programs. For example, if you have 3 Cool Setpoints on Monday and 2 Heat Setpoints on Monday,
this driver will merge the programs based on the amount of Heat Setpoints. You will lose 1 Cool Setpoint in this scenario.
If you have 2 Cool Setpoints on Tuesday and 4 Heat Setpoints on Tuesday, you will gain 2 Cool Setpoints when they merge.
From this point, the Heat and Cool programs will be in sync, based on what you see in Navigator.


License Key:
This is the license key purchased to activate the driver.

License Status:
This is the status of the license activation.

Thermostat IP Address:
This is the IP address of the thermostat, e.g.

Polling Frequency (seconds):
Set the data polling frequency in seconds. Please note that decreasing this value to less than
10 seconds could overwhelm the system.

This is the current status of the connection.

Debug Mode:
Used for debugging the driver. Output is displayed on the Lua tab.
Print and Log


This driver provides several device specific programming opportunities.

-PMA: Value
This allows you to write up to a 5 digit number to the Price Message Area on the screen.

-LED Control: Option
This allows you to control the LED on the front panel of the thermostat.

-Remote Temperature Mode: Option
This allows you to turn the remote temperature mode on and off programmatically.
Remote temperature mode allows you to supply a temperature value to the thermostat from a remote source.
The thermostat will then perform all HVAC operations based on the supplied value.
There are two ways of supplying this driver with the value. If you have a value you wish to pass that is
already of a STRING type, you may use the 'Remote Temperature' command.

If you have a value of a NUMBER type, you must set the RemoteTemp variable found under
this driver->Device Variables. You must then call the device specific command 'Update Remote Temp By Variable'

Your thermostat will continue to use the last supplied value as the current temperature.

-Remote Temperature: Value
Used for setting remote temp to a STRING value. Passing a value will automatically turn remote temp mode ON.

-Update Remote Temp By Variable
Used for setting the remote temp to a NUMBER value. This value must be set in Device Variables->RemoteTemp.
This command will then update the Remote Temp with the value inside Device Variables->RemoteTemp.
This command will automatically turn remote temp mode ON.
