I have 4 zones heat only but each location only has 2 wires, there is no C wire so they're analog controls.
This really limited my options to get WiFi thermostats or even just a programmable one. The problem is that these are all power hungry devices and even the most basic programmable needed a C wire.
I've been looking for something where I have a master controller (Tag Manager) that just sends commands to a low powered thermostat to control the temp.
This looks like what I'm looking for, will the Kumostat support a 2-wires only?
