The Zone Valve Control 306V connects up to six thermostats and operates zone valves to provide heating to a zoned hydronic heating system. The 306V operates a system pump whenever a zone valve opens. Zone 1 can operate either a zone valve or a circulator to provide heat to an indirect domestic hot water tank with optional priority over zones 2 through 6. The 306V includes optional exercising to prevent circulator seizure when not in use, and optional post purge operation of the domestic hot water tank to maximize energy savings. The 306V provides a RoomResponse™ signal to modulating-condensing boilers to optimize comfort while improving boiler efficiency.

The Smart Boiler Control 294 provides central and indirect domestic hot water heating or volume domestic hot water heating by operating up to four boilers. This can be expanded in groups of four boilers through the use of expansion controls up to a maximum of sixteen boilers. The 294 operates both condensing and non-condensing boilers that are either modulating, single, two, three or four-stage to provide a flexible, cost effective hybrid boiler plant solution. The Watts® OnSite web and mobile applications provide real-time remote monitoring, setting adjustments, and notifications.

The WiFi Thermostat 561 provides precise temperature control of a one-stage heating system. When connected to the Internet, the Watts® Home mobile app allows the thermostat to be controlled remotely. A 7-day, 4-event programmable schedule is available and the early start feature automatically learns to heat up the room by the scheduled time. An Away mode is quickly and easily accessed to provide energy savings when the space is unoccupied. The thermostat supports radiant floor heating and optional floor sensors can be installed to enhance comfort and protect floor coverings.

This white finish Invita® WiFi Thermostat makes upgrading easy by using the existing 2 wires from any living space to connect to an HVAC Interface Module in the mechanical room. It works with most types of heating and cooling systems including conventional, heat pump and dual fuel while offering fan, relative humidity and ventilation control. The Watts® Home app provides secure WiFi adjustment, remote temperature control and can send email notifications when there are problems with the HVAC system. The Invita WiFi offers a choice of five display screen color themes.

The WiFi Snow Melting Control 670 operates hydronic and electric heating equipment designed to melt snow and/or ice from roads and walkway surfaces. The control works with the tekmar Snow/Ice Sensor 090 or Snow Sensor 095 to automatically detect snow or ice and operates a single boiler, steam valve, or electric cable to supply heat to the slab. Boiler return protection is provided to non-condensing boilers using a mixing valve or variable speed injection mixing pump. When connected to the Internet, the Watts® Home mobile app allows the 670 to be controlled remotely.
