  • More Info

    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 only accepts commands from the transmitter that is 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.

    Varied Mounting Options
    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.

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

    Extra Venstar Receivers are also available for homes or businesses that have more than one HVAC system.

    • Auto Changeover, 2-Stage Heat & 2-Stage Cool for use with gas / electric or heat pump systems.

    GINA -- port st lucie, FL   6/24/2013
    Temperature displayed is consistently 3 to 4 degrees lower than existing thernmostat and separate room thermometer.
    SAM -- calabasas, CA   10/18/2012
    Excellent service from the staff and the whole organization
    WILLIAM -- new kensington, PA   4/4/2012
    Excellent product. Accurate, convenient, and reliable.
    Kevin -- san diego, CA   3/21/2012
    I have four of them and eventually they all lose their program and cant keep time. Even with new lithium batteries. They still work great 5 years later except I cant use them for programmed cycles because they wont keep the time.
    PAUL -- roswell, GA   2/10/2012
    I was replacing a dead hunter that used remote temperature sensors. I read a lot of review about difficulty installing. Yes the instructions are bad. However, I am guessing those folks never installed a thermostat before. Took 10 minutes to install and about 5 more to figure out the programming of the remote. I did re-route the antenna a bit to get clearer signal, there are a number of walls between the remote and the base. It came looped around itself which is not good for antennas, first I ran it out the little hole, but hanging down the wall was an invitation for trouble, so I carefully routed it around the inside of the case so it was clear of anything that could damage it. Works perfectly and having the controls sitting right next to me is nice.

    I have a 2 story great room that was always cold because our thermostat was located in a hallway. I installed this along with a Venstar T1900 Thermostat which also controls the humidifier and it works perfectly. I put this remote unit on a table in our great room and now finally our furnace is getting the proper temperature reading and our room is no longer cold. Much easier than relocating the old thermostat to a new location. Both units are easy to install and come with instructions that are pretty thorough. I made one call to tech support and got a return call the same day. Overall I am very pleased.
    C D -- los altos hills, CA   5/1/2011
    Product just as expected. However, Smarthome's insistence on requiring a signature on delivery without exception makes it difficult, so I unfortunately have to limit purchases to those only Smarthome carries.
    ROBERT -- oakland, CA   4/11/2011
    I received the item and it is working. I was disappointed that I had to repalce the original one tht was only about a year old but had stopped working. Hopefully this one will last longer. It works great when it works.
    PETER -- parkland, FL   3/10/2011
    Great product - have two working well. Only comment - design of enclosure somewhat dated.
    TED -- alamogordo, NM   2/9/2011
    This remote control sender is excellent. Rhis is the 3rd one I have bought in the past 3 years for 3 different central air units. Battery power is good enough, they last 1+ years.
    JOHN -- north vancouver, BC   1/5/2011
    Haven't installed yet
    DAVID -- palo alto, CA   9/16/2010
    Lacks some features, but a great value for the price.
    JOE -- jacksonville, FL   8/16/2010
    The sender worked fine, then ordered the receiver to update my system. receiver did not work properly, would turn on system, but would not turn it off. Returned it for replacement.
    ADAM -- falls church, VA   7/7/2010
    My only compaint with this product, is that its temperature sensor appears to be off. When placed directly next to several temperature measurement devices, it is always 2-3 degrees warmer. Our fix is to set the desired temp lower. We like this its pretty nice. Good product.
    comfortable at home -- boston   7/7/2010
    This is a wonderful product for anyone who wants to turn a single zone system into one that functions as a multizone. It has saved us significant money.
    JON -- arlington, WV   4/3/2010
    Works perfectly, and I'd recommend it to anyone needing completely portable temperature regulation. My only minor suggestion is aesthetic ... the "easel" stand design used by the sender/transmitter is awkward and fragile. It should be simply redesigned into an "L-shaped" stand-up feature.
    STEVE -- cumming, GA   2/4/2010
    The product works as advertised and is doing just what I needed, keeping a back bedroom at the correct temperature even though the receiver is in a hallway. Could use some diagram on how you take the unit apart to put in the batteries. Without the diagram you do not know for sure that you just basically pry the top and bottom off by prying at both ends.
    TED -- alamogordo, NM   12/11/2009
    I have these receivers and thermostats on two Central Air Units in my house and they perform excellently. For this last one, the old thermostat was in the middle of a wall on which I wanted to place a HD TV. I installed the wireless receiver instead of moving the thermostat to a different wall. Works perfect and is worth the money.
    JOSEPH T -- havertown, PA   11/22/2009
    This was an ideal solutionfor my heating reqirements unfortunately the receiver burns out at installation
