“Simple installation. Word to new buyers: The older units had a smaller casing. This new one is the same size across other multiple zone units (2 to 3 zones to 4 zones).”
“This is a great product to control your different zones/circulators and has proven to be very reliable. However, be careful using WIFI thermostats with this product as they may draw too much power off the 24-volt transformer and then cause the relay to go haywire.”
