Venstar's ColorTouch is a multifunctional, simple-to-use, richly featured, programmable touch screen thermostat that thinks it's a digital picture frame. ColorTouch has customizable backgrounds, including the users' own photos, and more than a dozen preset themes, including holiday themes.

T5900 includes all the great features as T5800 with the addition of a built in Humidity Sensors and ability to control humidification and dehumidificaiton

ColorTouch comes with more than a dozen built-in nature and holiday themes that can be used as background wallpaper for the thermostat. Each built-in theme has a separate photo displaying a daytime and nighttime scene, along with showing the sun for the day and the moon for the night. The daytime scene appears from 7:00am until the nighttime scene appears with the moon at 7:00pm. Holiday themes include Christmas, Hanukkah, Thanksgiving, Halloween and Cinco de Mayo.

Install up to 100 photos and display them as custom background wallpaper for the thermostat. With ColorTouch Assistant, you can customize your photos using the built-in editing features and can use the "preview" feature to see how the photo will look as background wallpaper once the thermostat info is placed over the photo.

Install up to 100 photos and display them as a slideshow when the thermostat is in screen saver mode. With ColorTouch Assistant, you can customize your photos using the built-in editing features, including zoom, rotate, color and brightness adjustments.

SD Card
Import & Export Settings. Easily choose what settings you want to import into your thermostat from an SD memory card including your Custom Photos, Dealer Info, Schedule, and Thermostat Name. Using the SD card you may save settings from an existing ColorTouch thermostat that can be exported to other thermostats (so you don't have to program each individual thermostat). The SD card is prepared using the ColorTouch Assistant software application.
(SD memory card, 64Mb minimum, sold separately)

Simple as You Want Operation
"Simple Stat" operation mode provides enlarged display numbers and fewer display items, making it perfect for the most basic users. "Simple as You Want" operation allows ColorTouch to be installed as a programmable or non-programmable thermostat. "Simple as You Want" operation also makes the thermostat easy to use. For example; it allows the user to remove the cooling references for homes without air conditioning.

Time Period Programming has never been so fast and simple to implement on a thermostat. The intuitive "Time Period" Scheduler automatically changes the temperature and mode for up to four periods per day. This allows for comfortable temperatures for sleeping, waking, and daytime, plus an energy savings mode for when no one is home. Customize every aspect of your "Time Period" Schedule with great flexibility.

At-a-Glance Screen
"At-a-Glance" screen shows the user heating and cooling status, as well as the room temperature. Heat and Cool indicators give "at-a-glance" information on heating and cooling, so users can easily see if air conditioning or heating equipment is on. An example of Heat and Cool indicators is on the left. The room temperature is 79 degrees and thermostat is cooling to 75 degrees. Room temperature is blue color to show the equipment is running. The ColorTouch thermostat can be wired with an Outdoor Sensor so that the outside temperature can be displayed right on the screen. The user has the option to display the high and low temperatures for the day.

ColorTouch is multilingual (English, Spanish and French).

Nighttime Dimmer
Nighttime dimmer for bedroom thermostats gives the user the ability to adjust the time the dimmer is on. Users can adjust the active brightness and the idle brightness with complete darkness being an option when dimmer is idle. When user touches the screen during nighttime dimmer operation, the screen's backlight temporarily returns to a useable brightness.

Energy Usage Info
Easy access to Energy Usage Information lets you easily see how much energy has been used to heat and cool for the past seven days. Runtime graphs help you evaluate energy conservation options, giving you the opportunity to decrease energy costs. View the heating or cooling runtimes separated by stages. Excessive runtimes indicate that it may be time for equipment maintenance.

With ColorTouch Security you have the ability to enforce temperature set point limits so that the system runs within set temperature parameters. Now no one can run the air conditioning too low or the heat too high. Security settings also give you the option for automatic screen lock. This locks the screen minutes after it has been touched. Unlocking the screen requires a pass code to enable access (eliminates kids or guests from changing the thermostat settings).

Daylight Savings
Daylight Savings mode automatically adjusts ColorTouch clock when necessary.

Customize the look of ColorTouch with faceplates to match your home decor. Options include white(supplied) - black, silver and wood grain each sold separately.

ColorTouch is compatible with most heating and air conditioning equipment and controls gas/electric or heat pump equipment, with up to 4 heating and 2 cooling stages. ColorTouch is also dual-fuel capable. ColorTouch is able to intelligently control the equipment. This intelligence also displays the proper equipment status, in terms of heating and cooling stages turned on.

When it is time to change a filter, time for maintenance, or the homeowner just wants to know who to call for service, this is the screen that pops up on the display. You can easily enter the text for this screen directly on the thermostat. If you want to add the company's logo or picture to this screen, ColorTouch Assistant software makes that easy to do as well. ColorTouch is installation-friendly with its output test screen that allows the installer to test the system. The graphical user interface shows which outputs are on, so the installer can ensure that all equipment is connected and working properly.

"My Thermostat" screen shows overall status of the equipment and thermostat in graphical panels. ColorTouch's current running firmware version can be determined using these screens. Since ColorTouch has upgradable firmware, using ColorTouch Assistant software users can upgrade their thermostat firmware with ease.

ColorTouch Assistant
With ColorTouch Assistant you can import and edit your photos from a drive on your computer, prepare them for use as the thermostat's screen saver, or choose a photo for a custom wallpaper background. ColorTouch Assistant allows you to configure your time period schedule and adjust your thermostat's installation settings from the comfort of your laptop or desktop computer.
