I'm using these to manage a geothermal heat pump with warm and cold water distribution to two air handlers, one radiant heat loop and a storage tank. There are multiple thermostats for each air handler with different stage 1 heating (e.g. radiant zone) and cooling (traditional condensing unit backup). I'm using three of these devices: one for each air handler and one to consolidate demand to the geo. They help me minimize non-standard custom relays so that, hopefully, the controls are a bit easier to understand. While not perfect for the task, they are very flexible and helpful. Their support team is also helpful.
