OUTDOOR AIR TEMP °F

Installation

The control automatically detects the presence of the outdoor air sensor. If an outdoor air sensor is present, the boiler automatically defaults to outdoor air reset for setting boiler temp. The parameters should be set according to the following table:

The set point of the boiler is controlled by an outdoor temperature sensor. As the outdoor temperature falls the setpoint of the boiler is increased. The boiler modulates to maintain this setpoint.

The setpoint is adjusted according to the above parameters. The boiler setpoint will be the maximum value (180° F) when the outdoor air is at or below a minimum temperature value (20° F). The boiler setpoint will be at the minimum value (80° F), when outdoor air is at or above a maximum temperature value (70° F). The setpoint for “in between“ values of outdoor air temperature, is linearly proportional to the above settings. Using the values in the table above, the boiler setpoint will be 80° F when the outdoor air temperature is 70° F. As the outdoor air temperature drops, the boiler setpoint will be increased until the outdoor air temperature is 20° F. At this point the boiler will reach its maximum setpoint of 180° F. If the outdoor air temp drops further, the boiler setpoint remains at 180° F.

The boiler shutoff temperature can be used to turn the boiler off at a given setpoint. For example if you wanted to shut the boiler off when the outdoor air temperature was above 65° F you would set the boiler shutoff temp to 90° F since this is the setpoint that is called for at 65° F outside air temp.
