Singular ControlThe Sola Hydronic Control orchestrates multiple hydronic boiler functions, based on user programmable settingsand priorities. Each boiler has a dedicated control, with an optional local keyboard display module for monitoring and setpoint adjustment. Configuration is accomplished using a system operator interface. Central Heating is the mainheating loop, while Domestic Hot Water comprises the optional secondary heating loop. User assigned priorities foreach heat loop dictate which is addressed first.

thinkGREEN

Keep green on the planet,keep green in your wallet.

The Sola Hydronic Control helps to save time, money and the planet!By using less fuel, less CO2 and other greenhouse gases are releasedinto the atmosphere. Also, reduced electrical energy use translates tofewer greenhouse gas emissions from utility companies.

Setback • Saves fuel by reducing boiler output temperatures for low use or unoccupied periods.

Outdoor Reset • Saves up to 10 percent on average fuel usage. • Adjusts boiler output temperature to compensate for outdoor air temperature changes, causing boiler to operate at lower temperatures during mild weather. • Reduces unnecessary boiler cycling.

Fan and Burner Modulation • Maximizes electrical energy savings and minimizes fuel use compared to fixed speed components. • Reduces fan speed and burner firing rate in response to modulation. • An ideal pairing with Premix components and Premix burner technology, which reduce NOx formation.

Money • Saves green with reduced installation, wiring and maintenance by integrating multiple control functions into a single device. • Keeps green in your wallet by reducing energy usage.

The Honeywell SolutionGet the Honeywell advantage by combining the Sola Hydronic Control with compatible Honeywell components for a compact and powerful hydronic control solution. For more information, visit customer.honeywell.com.
