Use fold out programming flow chart inside front cover

Fdt Drip Time Sets the period of time following the termination of a defrost during

which period nothing happens. This allows any residual moisture on

the evaporator time to drip down and drain away.

0 ÷ 255 mins.

Pr2 0

dPO First Defrost

after start up

Tells the controller whether to do an immediate defrost when the

power is switched on or to wait for the normal interval time as set in

parameter IdF. Can be used to make sure defrosts are not missed in

areas with unreliable power supplies.

0=immediate

1=After IdF

time

Pr2 1

FnC Fan

Operating Mode

Tells the evaporator fan to either run continuously ( apart from

during defrost ) or to cycle on and off with the compressor.

0=cycle with

compressor

1= Continuous

Pr2 1

Fnd Fan Delay Sets the time between the end of defrost and the evaporator fans re-

starting.

0 ÷ 255 mins.

Pr2 10 mins.

FSt Fan Stop

Temperature

Sets the maximum temperature ( sensed by the evaporator probe )

above which the controller stops evaporator fans from running

- 50 c ÷ 50 c

Pr2 - 1 c

Ot Thermostat

Probe Calibration

Enables the controller to be re-calibrated or off-set from the probe

temperature reading.

- 30 c ÷ 30 c

Pr2 0

OE Evaporator

Probe Calibration

Adjusts the off – set of the evaporator probe

- 30 c ÷ 30 c

Pr2 0

rES Resolution Turns the decimal point on or off. This gives a display resolution of

either 1 degree or 0.1 degree Celsius.

0=Off

1=On

Pr2 1

CF Unit of

Measurement

Sets the display to read out in Celsius or Fahrenheit 0=Degrees C

1=Degrees F

Pr2 0

COn Probe Fault

“ON”

Time

If a probe fault is detected the display will flash P1 and the controller

will automatically cycle the compressor on and off. This parameter

sets the “ON” time period

0 ÷ 255 mins.

Pr2 15 mins.

COF Probe Fault

“OFF”

Time

If a probe fault is detected the display will flash P1 and the controller

will automatically cycle the compressor on and off. This parameter

sets the “OFF” time period

0 ÷ 255 mins.

Pr2 30 mins.

dIC Digital input

mode

Configures controller’s response to an input on “Digital input 1”

0 = Generic alarm. Display will flash “EA”, alarm sounds and

alarm relay operates, controller continues to control as normal

1 = Important alarm. Display will flash “CA”, alarm sounds and

alarm relay operates, controller relays open to stop all functions.

2 = Serious alarm. Display will flash “OFF”, alarm sounds and

alarm relay operates, controller relays open to stop all functions.

3=External consent for defrost end: See technical manual

0 = Generic

1 = Important

2 = Serious

3=External

consent

Pr2 0

dId Digital input

delay

Sets the delay between an input being detected by “Digital input 1”

and the alarm being activated.

0 ÷ 255 mins.

Pr2 5 mins.

dOA Open door

alarm delay

Sets the delay between an input being detected by “Digital input 2”

and the “Door Open” alarm being activated. ( XR572C only )

0 ÷ 255 mins.

Pr2 15mins.

tBA Alarm Mute

On / Off

Allows or prevents muting of the alarm buzzer and alarm relay.

0 = Alarm cannot be muted, 1 = Alarm can be muted

0=Mute disable

1=Mute enable

Pr2 1

Ad 1-Ad 2 Serial

Address

This is only utilized when the instrument is being used as part of a

networked control system together with other controllers, all linked

back to a monitoring panel. It gives the controller it’s system address.

0 ÷ 94

Pr2 0 / 1

Ptb Parameter

Table

Shows in sequence every parameter’s label and then displays the

factory default setting for that parameter.
