Carrier 50RLP Configuration, Hardware Points 1 to 32 HWP01-32, Hardware Points 33 to 64 HWP33-64

CONFIGURATION

The Aquazone™ System Control Panel contains a Comfort Controller 6400 programmed using the standard algorithms and enhanced by BEST++™ custom programming. The BEST++ Templates for some of the programs have been removed to prevent field alterations. For other programs, the templates are included to allow for jobsite customization. For basic information about the algorithms please refer to the Comfort Controller Overview and Configuration manual (808-891). Default configurations are listed later in this section.

Hardware Points — The hardware points are shown in Table 11 and 12.

LOOP WATER FLOW SWITCH — This discrete input is used to provide a signal that one of the loop water pumps is on. If both pumps have been commanded to run and no water flow is detected, then the system water source heat pumps will run in the fan only mode for DDC (Direct Digital Control) coordinated heat pump controllers, while the system relays for thermostat systems will be turned off.

Loop Water Flow Switch:
Display Units	Discrete ASCII
Default Value	No
Display Range	Yes/No
Network Access	Read/Write

SYSTEM SUPPLY WATER TEMPERATURE — The sys- tem supply water temperature is the temperature of the water being pumped to the system of water source heat pumps. The temperature is measured by a 10K Thermistor (MCI). This output and sensor is required for proper function of the loop and heat pumps.

System Supply Water Temperature:

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

SYSTEM RETURN WATER TEMPERATURE — The sys- tem return water temperature is the temperature of the water returning from the system of water source heat pumps. This temperature measured by a 10K Thermistor (MCI). This output and sensor is provided for informational purpose and indicates the average load caused by the normal operation of the heat pumps.

System Return Water Temperature:

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

SYSTEM WATER PRESSURE — This sensor is used to measure the pressure of the supply water to the system of water source heat pumps. This sensor should be located 2/3 of the way down the supply water distribution piping or in a location that will provide a good reference of the supply water pressure. This sensor is used to control the speed of variable frequency drives pumping water to the water source heat pumps. Each water source heat pump may be equipped with a two position isolation valve that may be closed when the compressors are not energized in order to reduce the quantity of water being pumped through the system.

System Water Pressure:
Display Units	in. wg
Default Value	0.0
Display Range	0.0-5.0
Network Access	Read/Write
