is disabled.

Leaving Chilled Liquid Temperature Setpoints

– Setpoint

This display indicates the present setpoint to which the

chiller is operating, whether controlled locally or re-

motely.

Leaving Chilled Liquid Temperature Setpoints

– Shutdown

This display indicates the leaving chilled liquid tem-

perature at which the chiller will shut down to avoid

over-cooling. The default value is 4.0°F below the

leaving chilled liquid temperature setpoint.

Leaving Chilled Liquid Temperature Setpoints

– Restart

This display indicates the leaving chilled liquid tem-

perature at which the chiller will restart after the chiller

has shut down due to over-cooling temperature. The

leaving chilled liquid temperature setpoint is the de-

fault value for this setting.

PROGRAMMABLE
Local Leaving Chilled Liquid Temperature –

Setpoint

Access Level Required: OPERATOR

This value allows the user to define the leaving chilled

liquid temperature that is to be maintained by the chill-

er. The temperature is programmable over the range of

38.0°F to 70.0°F (water) or 10.0°F to 70.0°F (brine).

The range is 36.0°F to 70.0°F (water) if Smart Freeze

is enabled (see below).

Local Leaving Chilled Liquid Temperature –

Range

Access Level Required: OPERATOR

This is the range that a remote device is able to adjust

the leaving chilled liquid temperature setpoint above

the temperature set locally at the OptiView. The range

setpoint is programmable to either 10°F or 20°F, with a

default of 20°F. This setpoint value is added to the lo-

cal leaving chilled liquid temperature (see above) val-

ue to create a range limit over which a remote device

can adjust the setpoint.

• For example, if the range is programmed for 10°F

and the locally programmed value of the chilled

liquid temperature is 45.0°F, then the remote de-

vice is able to change and set the leaving chilled

liquid temperature setpoint over the range 45.0°

- 55.0°F.

A remote device that provides an analog signal (0-

20mA, 4-20mA, 0-10VDC or 2-10VDC) in analog re-

mote mode or a PWM signal in digital remote mode

defines the setpoint change as an offset value.

• For example, if the setpoint is 45.0°F and the de-

sired setpoint is 50.0°F, then 5.0°F would be the

input on the remote device.

A MicroGateway (in ISN Remote mode) can define the

setpoint through a serial data stream. In this case, the

incoming setpoint is not an offset that is applied to the

leaving chilled liquid temperature setpoint value, but is

the programmed as the actual setpoint value.

Leaving Chilled Liquid Temperature Cycling

Offset – Shutdown

Access Level Required: OPERATOR

This value specifies the number of degrees below the

leaving chilled liquid temperature setpoint the chilled

liquid can reach before the OptiView performs a

“LEAVING CHILLED LIQUID – LOW TEMPERA-

TURE” cycling shutdown. This setpoint is program-

mable over a range of 1°F to 64°F (dependant on

setpoint temperature), to a minimum cutout of 36.0°F

(water), 34.0°F (water with Smart Freeze enabled) or

6.0°F (brine). This prevents over-cooling of the chilled

liquid.
Anytime the leaving chilled liquid temperature setpoint

is increased, the shutdown threshold is 36.0°F (water)

or 6.0°F (brine) for the next ten (10) minutes. If Smart

Freeze is enabled, the threshold is 34.0°F for the next

ten minutes. After ten minutes have elapsed, the shut-

down threshold becomes the programmed setpoint

value.

Leaving Chilled Liquid Temperature Cycling

Offset – Restart

Access Level Required: OPERATOR

This value specifies the number of degrees above the

leaving chilled liquid temperature setpoint the chilled

liquid is permitted to reach before the chiller will re-

start after a “LEAVING CHILLED LIQUID – LOW

TEMPERATURE” cycling shutdown. The value is

programmable over a range of 0°F to 70°F (depen-

dant on setpoint temperature) above the chilled liq-
