Essential Info

Did you ever wish you could turn up the heat without getting out of your warm cozy bed? Or that you could turn down the air conditioning from your living room chair? Or put the thermostat in a newborn baby's room to keep the temperature exactly right? If you wish to be able to move the thermostat, put it by your bedside at night, or even control your heating and air conditioning system from two different places, such as upstairs and downstairs, then the Venstar Wireless Thermostat is for you.

Here's how it works: Remove your old wall thermostat, replace it with the Venstar receiver and then remotely control the temperature anywhere in your house with the Venstar thermostat. Add additional wireless thermostats around your house (up to 4) and have instant access to temperature control no matter where you are.

Wireless Thermostat and Receiver


What's Included

  • Venstar wireless thermostat controller
  • Venstar wireless receiver
  • 2 AA lithium batteries
  • More Info

    This kit consists of two parts, a thermostat and a receiver. The thermostat is a wireless, battery operated unit that can be placed in any location in your home (up to 500ft. from receiver) and will transmit radio signals to the receiver which replaces your existing wall thermostat. This thermostat allows up to 4 time/temperature settings to be programmed per 24-hr period and stores programs for 7 independent days.

    Place Receiver Wherever Wires Are Available
    The receiver is easy to install and is wired just like a standard 24VAC thermostat. Connect the unit wherever existing wires are available; the old thermostat location, in a furnace closet, in an attic or basement.

    Place Thermostat in Most Important Rooms
    Once the receiver is installed, the thermostat can then go anywhere in the building, and it will transmit radio signals back to the receiver. The transmission range is up to 500 feet, and it works through walls, floors, ceilings, etc. The temperature sensor is located on the thermostat, so place the thermostat where temperature control is most important to you — your bedroom, the boss's office, a baby's room, etc. The thermostat runs off of 2 AA lithium batteries (included). The Venstar Wireless Thermostat can be mounted to your wall, carried in your hand, or set on a table or shelf using its built-in easel stand.

    If more than one transmitter is used with a single receiver, the transmitters must be given different Unit ID Numbers. Only the transmitter with Unit ID Number 1 may have a programmed schedule or be configured. All configuration parameters are taken from the transmitter with Unit ID Number 1. Transmitters with Unit ID Numbers 2, 3, and 4 cannot be programmed or configured (except for set points).

    When more than one transmitter is used, the receiver will only accept commands
    from the transmitter that was last used (button pressed). All other set points and modes from other transmitters are ignored. If the transmitter with Unit ID Number 1 has a schedule and is in Program On mode, the receiver will revert back to following the programmed schedule when a time period change occurs, even if the transmitter with Unit ID Number 1 is not the current commanding transmitter.

    Note: To install batteries, insert a small screwdriver in the slot between case halves and carefully pry the case apart.

    Additional Features Include:
    • Auto Changeover, 2-Stage Heat & 2-Stage Cool for use with gas / electric or heat pump systems.
    • Thermostat is completely wireless, receiver can be mounted at unit or at old thermostat's location.
    • Transmits at 418MHz using pulse code modulation — won't interfere with other wireless systems
    • Transmitter uses two AA batteries (included)
    • 7 Day Programmable with 4 time periods per day, copy command and holiday mode
    • Dual-setpoint with adjustable deadband (1 to 6 degrees) and temperature sensor calibration.
    • All programming stored in nonvolatile memory.
    • Thermoglow Electro-luminous Display.
    • Display shows heat and cool setpoints, mode, and room temperature simultaneously.
    • 5 minute compressor time guard and adjustable cycle limit, both overrideable for servicing equipment
    • Setpoint adjustment range from 35° to 99° F, sensing range from 32° to 99° F.
    • 64 house codes allow installation of up to 64 systems within transmit range with no interference.
    • On board dry contact closure available to force thermostat into occupied operation.
    • Meets California Commercial Title 24.

    NANCY -- martin, MI   6/26/2014
    easily installed and works great!
    PATRICK -- foster city, CA   4/5/2014
    Wireless Thermostat works great! Service was good, and I'm happy.
    Pattie -- Pennsylvania   2/27/2014
    Easy to install and works as advertised. My only complaint is that the listing on the website did not make it clear enough that I needed to order a separate adapter for my 2-wire heat-only thermostat. Once I received that all went smoothly.
    ST. PAUL -- n.canton, OH   1/17/2014
    works Great!!
    PETER -- warrensburg, NY   1/16/2014
    The operation instructions provided a slight challenge, but once I figured them out the unit works perfectly. Now when the fireplace is used I place the sending unit in another room which allows the the rest of the house to remain warm. Great product!
    ALEXANDER -- chicago, IL   1/11/2014
    Working better than I could have expected.
    STELLA -- normangee, TX   12/19/2013
    This thermostat works exactly as stated. Where our original thermostat is located is right in the middle of a wall where we needed to put a large piece of furniture. Using this wireless receiver has allowed us the use of that space for our furniture. I couldn't be more pleased with this thermostat!
    MIKE -- colbert, WA   12/16/2013
    Installation was quick and simple. Had it running in 30 minutes or so. We really enjoy being able to take the remote thermostat into our room at night. Mornings are perfect temps now!
    LEROI -- seattle, WA   12/13/2013
    These have made a huge difference in the comfort level of our house. We are able to accurately set the temp for the area of the room we spend the most time in.
    LOC -- san jose, CA   12/10/2013
    It works great. It is very convenient. I could bring to any room that I want. Closed all the vents in any unoccupied rooms. The temperature reading is off by 2-3 degree. Other than that, I'm very satisfied with the product.
    Wade -- vancouver, BC   9/8/2013
    I bought this plus the two-wire heat-only kit because the wire between my ground-floor boiler and third-floor thermostat broke somewhere in the wall, and I chose this instead of ripping off drywall on three floors to run new wire. I think I made the right choice. It arrived faster than I expected, it took less than an hour to install with me working slowly and carefully, and it works perfectly so far.
    SANT -- arlington, TX   3/31/2013
    Great product. Works great and easy setup.
    KENDALL -- ringwood, NJ   3/25/2013
    Temp reading is off by 3-4 degrees. It also takes a long time for it to react. With the extra 2 wire relay I needed to purchase in order to run my oil furnace, it cost me over $200. I would not buy this unit again, nor would I recommend it.
    RICHARD -- nesconset, NY   3/21/2013
    100% Satisfied I'm thinking about purchasing an additional unit for another part of my house.
    RICHARD -- colo, IA   3/14/2013
    Installation is easy, programming is a little awkward, function is very good.
    MARK -- mason, NH   2/25/2013
    The product would not work with my heating systemand I had to return it. Great support from matt in customer service to help me figure out the problem
    MARK -- merrimack, NH   2/9/2013
    I have two things to say. 1 **** - As far as the concept, installation and product, I think it's great. It's perfect for someone who can't or doesn't want to run wires to move their existing thermostat. 2 ** - I'm not happy about the programming. I program all my temperatures to 60, but when I go into auto mode, all the settings are displayed as 67. I've reprogrammed multiple times to different values and can't get them lower. So I keep the system in the off position most of the time because it keeps my heat hotter than I want. if I could program all my temps to lower values, I'd give it five stars.
    CRAIG -- belpre, OH   12/27/2012
    This was a great purchase and was very easy to install. The only thing is that there is about a 2 degree difference before it turns on, but once you know that the adjustment for the temperature works fine. The house stays much warmer now and figure when summer gets here it will stay cooler. It is great to be able to put the unit in any room that you want and can't believe what a difference it made in how the whole house stays warm now and the furnace runs less. If you have a problem like I did where you can't move the wired thermostat and it was in a bad spot (on a wall that the fridge was on the other side of wall and made it about 5 degrees warmer than the actual temp due to heat from the fridge) then this is the item for you. Like I said took about 2 minutes to hook up, super easy to do! Extremely happy with this product!
    CINDY -- bluff dale, TX   12/16/2012
    Defective product...when it said AC was on the heat would be running and when it said heat was on the AC would be running. It was all wired correctly because our system works like it is supposed to with our original equipment. Very disappointed in product and we weren't able to just return it for a refund because it had been 30 days and not in original packaging. It would have been to much trouble to have sent it to manufacturer for return. DO NOT BUY PRODUCT.
    JOHN -- gloucester, MA   12/1/2012
    Out standing made a room have control of heat it did not have before.
