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.

Table 11 — Hardware Points 1 to 32 (HWP01-32)

Table 12 — Hardware Points 33 to 64 (HWP33-64)

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.

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 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 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

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.
