Carrier 50RLP installation instructions Software Points 65 to 96 SWP65-96

HEAT SOURCE 2 SPEED/LEVEL — When the Aquazone™ system control panel is configured for modulating heat source, this point displays the percent open or percent heat capacity requested. When the Aquazone system control panel is equipped for staged output, this point displays the percent of stages commanded. The actual number of stages active will be determined by the staging cards ordered with the Aquazone system control panel. See Table 8. The value displayed is determined by a PID loop set to control the supply water temperature at the Occupied Low set point.

OUTSIDE AIR TEMPERATURE — This software point is included to receive an Outside Air Broadcast. If the system is set up with Outside Air Broadcast, a control force will be displayed on the OAT point of all system controllers. For systems with factory-installed PremierLink™ controllers, the individual unit leaving water temperature sensors are connected to the OAT point. When OAT broadcast is enabled, the leaving water temperature sensors connected to the PremierLink controllers may be displayed temporarily by removing the Outside Air Broadcast force. The Outside Air Broadcast will be refreshed the next time the outside-air temperature is broadcast.

Outside Air Temperature:
Display Units	degrees F (degrees C)
Default Value	–40.0
Display Range	–40.0-245.0
Network Access	Read/Write

LEAD PUMP CONSTANT FLOW — When the Aquazone system control panel is configured for constant flow, this point displays the current lead pump. This point may be forced to keep the lead pump the same for more than the maximum hours difference required for pump rotation. When the pump runtime hours difference becomes greater than the maximum number configured the pump runtime hours for both pumps will reset to zero.

For example, the default maximum hours difference for rotation is 50 hours. If the Lead Pump was forced to 2, so that pump 2 is the lead pump, then the pump 2 runtime hours will accumulate until the difference between the pump 1 and pump 2 runtime hours becomes greater than 50. The both will reset to zero and pump 2 will start accumulating again.
