Universal Zone Control (4 Zones)

The Universal Control can control your zone pumps, zone valves or both. It is a perfect companion for condensing boilers with three (3) programmable end switches – allowing users to configure a condensing boiler that has multiple inputs such as central heating, DHW and low temperature zone. The control has a dedicated 115 V ac terminal to supply power to a boiler loop pump for primary/secondary piping system. The thermostat connection: Tr-Tw-C can be used to power digital Wi-Fi thermostats as well as power robbing thermostats. It can also be used with any standard efficiency or tankless coil boiler. During a power loss, the digital LCD user display and programming interface maintains programming.
