Review: Works great - was able to extend the reach of my sensor by myself - The control unit I bought came with a 2' sensor lead on it - found this one and was able to change it out (2 wires) and extended my reach quite a bit. Worked perfectly for setting up my outdoor wood boiler after a fire burnt up my old control unit - I was able to mount this controller off the unit in a protected area so if there ever is a flame up the control box will be safe. ## Features - Easy-to-read, bright, adjustable backlit LCD screen displays the temperature, parameters - Basic and advanced programming menus allow you to easily set up your control application on the LCD using a simple three-button touchpad interface - Adjustable On and Off temperature set points enable easy to set up cooling or heating control - Package Dimensions: 2.032 L x 14.605H x13.97W(centimeters) ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 5.0 out of 5 stars 3 Reviews | ## Images ![Johnson Controls A99BB-600C Penn Series A99 PTC Temperature Sensor, Compatible with A421 Control, 2" Standard Probe with 19' 8-2/5" PVC Cable, Gray - Image 1](https://m.media-amazon.com/images/I/61+balbXwXL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works great - was able to extend the reach of my sensor by myself *by K***R on November 10, 2021* The control unit I bought came with a 2' sensor lead on it - found this one and was able to change it out (2 wires) and extended my reach quite a bit.
