## Customer Reviews

### ⭐⭐⭐⭐⭐ It works, that's big deal for most DIY
*by J***I on December 26, 2024*

Though the size not fit to my Honeywell old furnish. All of the power connections and signal connections are works fine, same as my old relay box, there is third zone for me to use in my 2 zone system.

### ⭐⭐⭐⭐⭐ Read the instructions
*by S***R on October 8, 2022*

First one ordered did not work. Even after the burner circuit was set for 24 VAC, it would not work. When it was bumped, it would work, so there must be a loose wire or connection. Not reliable for normal use. Hats off for Amazon's quick replacement, but I did not want to go through a another tedious installation to see if the replacement was NG, so I bench tested the replacement. After setting the burner circuit for 24 VAC and since the room temperature was much lower than the sensor would need to work, connecting it to power and closing the thermostat to simulate a call for heat, and using a VOM to test the connections - it worked! 120 VAC for the circulation pump, and 24AV for the burner! All without having to deal with the silver sensor glop.

### ⭐⭐⭐⭐⭐ Easy fix boiler issues
*by E***. on January 2, 2015*

Product was new in box and easily installed. I would pay particular attention to the thermostat setting as it arrived preset on a higher than suggested temperature and could damage some in floor installations at the higher temperatures. The installation instructions are clear and easy to follow. If you have a cam phone or iPad it is helpful to record all the wiring so that it goes back together correctly. My boiler pilot was repeatedly flaming out but I remedied that by wrapping the capillary tube from the pilot to the gas control with fiber glass insulation. The combustion air comes from an exterior supply and can get cold enough to extinguish the pilot. An easy fix.PSDon't overlook the little jumper in the plastic envelope that completes the connection from the thermostat. READ THE INSTRUCTIONS FOLKS!!! It joins the two horizontal bottom screws at the bottom of the thermostat terminals. It will not function without this jumper!!!
