thermostat such as Honeywell's VisionPRO
VisionPRO
how Does It Work?
The AQ2511B0 Panel saves energy by automatically adjusting
the boiler's water temperature based on outdoor temperature.
This allows the boiler to exactly match the heat it provides with
the heat lost by the house. It's like temperature cruise control for
your customers house!
The greatest energy savings is in the colder seasons where lower
boiler temperature produces longer boiler run times, less cycling,
more even heating of the house and less standby losses of heat
going up the exhaust vent or into the boiler room where it's not
needed.
