“I bought this as a replacement for a taco zone controller that failed after 9 years. I got the expandable version this time as it has more features beyond just being expandable - specifically it has a setting for "exercising" the valves and pumps every 2 weeks to prevent them from seizing up over the summer. My thermostats have a similar setting to exercise the system but I like that I have the option of offloading this feature to the zone controller if I ever change out my thermostats. For the price difference of $11, I don't know why they sell the non-expandable version.”
“Installed this unit to replace a rat's nest of wiring along with some new t-stats. Definitely cleaned everything up and made it much easier to see what was happening/which t-stats were calling for heat, etc. With that said, the unit failed in about 8 months. 1 zone went completely dead (no power) and two others had a flickering power light. Had to buy a new unit at high cost and replace it to resolve no-heat situation. Have had other Taco's with no issues for a long time, very frustrated with this one.”
“The zone control. Was shipped on time and delivered without physical damage to outside of the box. There was a delay at job to install control. Once opened, the box had the control board with broken clips and loose board internal damage. Since I needed to get the boiler system back online, I attempted to install, but the second transformer was overheating, and the respective zones were not functioning properly. A return request was sent. I had to buy a taco controller locally.”
“They had the right product at the best price! They also have the longest warranty/return policy. The hardest part of upgrading to new thermostats with C wire and modern controls was all about taking out the old WR valves and putting in the new Taco valves. The wiring is totally self-explanatory and the options are great. We made one mistake on a thermostat, but the circuit board fuse did its job! swapped it out and all was good. This is an even better value given the transformers are integrated (a $50 value).”
