Essential Info

The Venstar T1900 7-Day Programmable Thermostat can help users save energy, and thus money, by running your heater and air conditioning only when you're at home. The 7-Day Programmable Digital Thermostat allows for the flexibility to leave the heater off while a home is vacant and then activate as you leave work to ensure your home is comfy upon walking in the front door. Because we live and work on schedules this Thermostat can too. Being 7-day programmable means it can be set to optimally run each day according to your schedule whether it's varied or the same each week and because it is ENERGY STAR rated it will run efficiently while in use. This thermostat is compatible with heat/cool, heat pump, and dual-fuel systems along with being able to control up to three heat stages and two cool stages.

  • More Info

    Easy to Program
    Programming the 7-Day Programmable Digital Thermostat is easy, thanks to a bright backlit display and button legends. If you're setting up multiple thermostats in your home to control the temperature in different zones, you can even program them using a Venstar EZ Thermostat Programmer (sold separately), which lets you upload your settings to different rooms quickly.

    Adjust the Temperature Remotely Via Phone
    Connect the Thermostat Telephone Controller (sold separately) to your thermostat, and you'll be able to call in and adjust the temperature using touchtone buttons or voice recognition commands.

    Automatic or Manual Temperature Adjusting
    Just because you've set up your system doesn't mean you can't adjust the temperature manually when you're at home. For maximum ease of use, you can even use the Thermostat IR Control & Receiver, which lets you adjust the temperature from the comfort of your sofa using a wireless remote!

    Additional Features
    Control a compatible humidifier by using the optional humidity module included with your thermostat. This accesory also allows your thermostat to display relative humidity levels or trigger a dehumidity process. Additional features include an auxiliary heat indicator and the option of adding an outdoor sensor.

    Additional Programmable Thermostats Available
    The 7-Day Programmable Digital Thermostat is also available for use if you don't have a dual-fuel system. A 1-Day Programmable Digital Thermostat is also available, sold separately.

    Do you currently have an INSTEON network in your home? If so, you can use the INSTEON Thermostat Adapter. When in use with the INSTEON RemoteLinc wireless remote, you can have the same wireless control of your HVAC system, and still retain manual adjustments at the thermostat itself.

    Please note: If you do not have a "common" wire running to your thermostat from your heating/cooling equipment, you may need either to run a new wire or to install a thermostat Add-A-Wire Accessory kit.

    It's nice to have humidity control at the touch of my fingers.
    Dale -- naperville, IL   11/5/2011
    Though this thermostat did not support heat pump control with two stage compressor for heating and cooling, I sent it to Venstar and they upgraded the firmware for free for this application. Venstar was very helpful.
    RICHARD -- bartow, FL   9/22/2011
    I am very pleased with the thermostat. It is doing every thing I hoped it would do for me, especially the humidity control feature. Good service and quick delivery on a quality product.
    REED -- carrboro, NC   9/8/2011
    This product has an amazing array of functions for the homeowner that wants more efficient and better functioning climate control. I use the remote wireless temperature sensor with this thermostat to better control bedroom temperatures when the thermostat is mounted in the hallway upstairs. Before I had this thermostat I had to open the bedroom doors to air condition the hallway (no vent there) and let all the cool air spill downstairs. If I didn't, the AC would have run all night trying to meet the setpoint temp where the thermostat is mounted. Now I can close the doors and condition just the bedrooms since there is a temperature sensor wirelessly sending the bedroom temperature to the thermostat in the hallway. Great product albeit a tad expensive. However, it will quickly pay for itself.

    Review for 7-Day Programmable Thermostat, Dual Fuel Item# 30412A with the Venstar Add-A-Wireless Thermostat Kit Item# 30419 I've been searching for a thermostat for my heat pump / central A/C that would do the following. 1) Lock out the emergency heat strips (2nd stage heat) durring smart recovery. 2) Lock out the heat pump when heat strips are running. 3) Programable 4) Runtime display for heat and A/C 5) Optional wireless remote sensors This unit dose all this and more, I'd bought two other thermostats from other Mfg. over the past year only to be disapointed. I ordered this with the optional Venstar Add-A-Wireless Thermostat kit and they work very well. Our FL off grade home has 10-12' ceilings, the wired thermstat was in a hall near a return, temp in living areas was always to hot or cold, with the remote thermostat we put it in the L.R. durring the day and MBR at night, now the temp is always right. Had it about 6 weeks, was a bit more expensive than I wanted to pay, but now that I have it our home is much more comfortable all the time,so far very pleased.
    JONATHAN -- centennial, CO   12/28/2010
    Great Item. Easy install, very nice looking. Much better Thermostat than any other I have seen at lowes or home depot. I like the fact that this can be upgraded to do almost anything.
    NATHAN -- fresno, CA   6/24/2010
    This thermostat has tons of features, some of which will even improve the functionality of basic HVAC units (like mine). It was easy to install (once I first installed the "Add-A-Wire" device since I only had 4 thermostat wires). Setting parameters was not completely intuitive, but the instructions were specific and descriptive enough to set each item as needed for my HVAC system. Programming daily temperatures thresholds was simple. Though I can't definitively attribute it to this thermostat, I did notice about a 10% reduction in energy costs starting the month I installed this thermostat, replacing my old 1-day programmable unit, and that's with increasing outdoor temperatures over that month. One complaint: this unit does not support daylight savings time so you'll have to manually change the time on this unit twice a year if you're in an area that observes daylight savings time. For a thermostat this advanced, you'd think they could add something as basic as automatic DST switching.
    MARCEL -- houston, TX   12/11/2009
    This thermostat is great! I especially like the "smart recovery" feature, where the thermostat learns to achieve the target temperature by the time the "morning" set-point is reached.
    JASON -- torrance, CA   11/7/2009
    Lots of features, works exactly as advertised.
    Larry -- Ann Arbor MI and Naples FL   12/27/2008
    This thermostat is very good - I'd buy it over the T1700 and T1800 because it has the humidity module which give accurate humidity readings built in. It was easy to install and does everything the T1700 and T1800 thermostats do plus more. Quite a piece of technology for the price. I also have mine one the Insteon wireless network and internet and all works well - 5 stars
    JOSEPH -- waldorf, MD   8/29/2008
    The thermostat worked exactly as I wanted it to. I love the humidity control using your AC mode.
    LONNIE -- st. louis, MO   6/5/2008
    Thermostat did not controll 2 Heat Pump Stages, only one. This needs to be described in the literature better so you do not buy this is you have a 2-stage heat pump.
    IAN -- severna park, MD   4/10/2008
    Professionally installed. Works well and the Comfort Call addition is brilliant!
