### ⭐⭐⭐⭐⭐ 







  
  
    Used with Lathem Time Clock
  

*by S***7 on Reviewed in the United States 🇺🇸 on October 2, 2022*

We needed this to go between a new Lathem time clock and an existing bell system. We couldn’t understand how to install it so we had to call the electrician who sorted it out.Once installed it’s worked perfectly.

### ⭐⭐⭐⭐ 







  
  
    Used to add an additional zone
  

*by B***E on Reviewed in the United States 🇺🇸 on October 18, 2020*

I already had a 6 zone Taco relay that was being fully utilized so I purchased this unit to add an additional heating zone.  The item is simple to wire and is working well.  My only complaint is that it makes a slight humming sound which is audible in the room above my boiler.

### ⭐⭐⭐⭐⭐
