Water set point temperature is determined based on outside air temperature. Correlation between water set point and outside air is always linear; therefore only two temperature points need to be specified:
- Water Set Point at 0 deg F outside temperature
- Water Set Point at 60 deg F outside temperature.
Water set points at both outside air temperature points are configurable based on the boiler and heating system in place. These values can be configured to meet requirements of specific boiler and heating system in place.
Wi-Controller-B Data Representation
Wi-Controller-B is a stand alone controller, which operates independently from the wireless network. All set points and control rules are stored on the device and commands are executed within the device. Wi-Controller-B operation is not susceptible to network or database communication failures. Because all decisions are made locally on the device, Wi-Controller-B will continue to operate. However, monitoring can be affected if:
- Server communication failure – Wi-Controller-B will continue normal operation. Wi-Site will continue to log data from the wireless network until its flash memory is full. Data will no longer be logged once the memory is full. An alarm condition will be initiated and sent to users.
- Wi-Controller-B to Wi-Site communication failure – Wi-Controller-B will continue normal operation. An alarm condition will be initiated and sent to users about communication loss.
In case of Wi-Controller-B hardware failure or sudden power loss, boiler system will default to “Always On” if correctly installed on normally closed relays. An alarm condition will be initiated and sent to users about communication loss.
