Honeywell C7189U1005 Hardwired Indoor Remote Sensor

Replaced old ,out of resistance sensor. Worked perfectly

This wired remote tells the VisionPro thermostat the temp, in any indoor space, where the remote is mounted. It does not sense humidity. I put one in my master bedroom, because the thermostat was in a non-related hallway (not even served by the same heat pump). You'll need to program your thermostat to use the wired remote temp sensor. If you don't have the installer pamphlet that came with your thermostat, search the model number online and find a manual for installer programming. The code to enter programming is on the back of the thermostat, when you remove it from the sub-base. There will be a sticker with four digits. If you can't run a two conductor cable from your thermostat to this remote temp sensor, you can buy a wireless indoor remote temp sensor, instead. I also recommend adding a wireless outdoor temp sensor. With an outdoor sensor, you can program your thermostat(s) to lock out electric or other aux heat above a certain outside temperature. That's the only way you can prevent aux heat from turning on, when you raise the temperature setting manually by 2° or more. A single outside wireless temp sensor can be associated with multiple VisionPro thermostats in a house. For any of the wireless accessories, make sure your VisionPro has the RedLink feature. (Most do.)

We have these all over our campus on Ecobee thermostats and they work well. We only have to adjust the sensor if the wire run is long. I took off a star because once they are mounted to the wall, the cover seems to come loose with very little pressure—even when we barely tighten the mounting screws.

Honeywell temp sensor looked at numerous stores found on Amazon most reasonable price I use it for my apartment building they were a good price I bought 2 of them!!!

Two were ordered and both were defective

Installed this in a building that had the thermostats located on the opposite side of the room from the returns. It had been this way for 20 yrs. Installed these above the returns and configured the thermostat to look at them. Auditorium temps now stable within 1 degree and most everyone is comfortable most of the time. Completely changed the climate of this building for the good. Very easy install. Does require 2 conductor thermostat wire to be run from the unit to the thermostat.

Fast and great value. Works perfect

All of the Honeywell thermostats I've found only allow one wired remote sensor input. there is only one remote sensor input which means that all of the sensors (if you want multiple rooms monitored) have to be tied together. You cannot measure the the temp of each remote sensor separately. The indoor sensors are just small resistors and have to be wired together very specifically to accurately tell the average temperature of the combined rooms. Depending on the amount of sensors you have, you may have to wire them in series, parallel, or a combination of both. It can be very confusing if you do not have a background in circuits. So, because the thermostat doesn't have multiple sensor inputs, you could possibly have an issue if you have a sensor in a cold room and a sensor in a warm room. The thermostat will average them and think those rooms are fine. You are then stuck with adjusting the room's dampening vents by how the room feels instead of accurate temperature readings. I bought three sensors, because I had three bedrooms upstairs, and decided to return one after reading how difficult it was going to be to run wiring between the sensors to make sure they are both in parallel and in series. Check out the wiring diagrams on the manual http://siglercommercial.com/wp-content/uploads/2013/08/HONEYWELL_REMOTE_SENSOR_C7189_INSTALL.pdf I decided to install two sensors and will adjust the air vents based on feel for each room. It should do the same thing and keep the rooms very comfortable, just more manual effort.
