SYSTEM OVERVIEW
The Ecomatic HS2102 is a weather responsive control that is designed for residential
heating systems with a single type of radiation, such as fin tube baseboard, panel radiators,
or cast iron radiators. It can also be used to control and prioritize an indirect fired domestic
hot water tank.
The control provides the following features:
• Boiler water temperature modulation based on outdoor temperature.
• Domestic hot water priority.
• 7-day programmable clock.
• Daytime and nighttime temperatures.
• Room temperature compensation with optional BFC room sensor.
• Manual override switches for emergency operation.
• Freeze protection for heating system; constant circulation in nighttime below freeze
temperature.
• Freeze protection for indirect hot water tanks; maintenance tank at a minimum of
50°F (10°C) in night mode.
• Malfunction display for system troubleshooting.
• Standard non-adjustable 100°F/104°F pump logic for condensate protection of the boiler.
• Pump kick during vacation and summer operation; the control will operate pumps for
1 minute at 12:00PM every Wednesday to prevent pump seizure.
