REGULATION
SP Set Point Sets the temperature at which the compressor stops LS to US V5 c
HY Differential Sets the number of degrees above Set Point at which the
compressor is re-started
0 1 ÷ 25 5 c
V2 c
LS Lower Set
Point Limit
Sets the lowest temperature to which the customer can adjust the
Set Point
- 50 c ÷
Set Point
H- 50 c
US Upper Set
Point Limit
Sets the highest temperature to which the customer can adjust the
Set Point
Set Point ÷
150 c
H150 c
Ot Thermostat
Probe Calibration
Probe offset adjustment – thermostat
- 12 ÷ 12 c
V0 c
Ods Delay of
Outputs on Start
Up
Sets the time delay between the power to the controller being
turned on and any output relay starting to operate. This can be used
to prevent short cycling of the compressor following a momentary
power failure.
It can also be used to stagger the re-start of multiple units following
a power failure, to prevent everything trying to start at once and
blowing a fuse.
0 ÷ 255 mins.
H0 mins.
AC Anti Short
Cycle
Sets the minimum time period between the stopping of the
compressor and it’s next possible restart
0 ÷ 50 mins.
V1
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.
H30 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.
H30 mins.
CH Cooling or
Heating mode
Sets the controller for heating or cooling applications.
Cooling – Differential is above the Set Point
Heating – Differential is below the Set Point
CL = Cooling
Ht = Heating
VCL
DISPLAY
CF Unit of
Measurement
Sets the display to read out in Celsius or Fahrenheit
C = °C
F = °F
HC
rES Resolution Turns the decimal point on or off. This gives a display resolution of
either 1 degree or 0.1 degree Celsius.
in = Off
dE - On
VdE
ALARMS
ALC Alarm
Configuration
Configures the alarm either to absolute temperatures or
to be relative to the Set Point ( i.e. so many degrees
above & below Set Point ) If “Relative”, when the Set Point is
altered the alarm levels will follow it
rE = Relative
Ab = Absolute
HAb
ALU Alarm
Level Upper
Sets the high temperature alarm level. If ALC = rE it sets how
many degrees above Set Point. If ALC = Ab it sets a fixed alarm
temperature.
Set Point ÷
150 c
V150 c
ALL Alarm
Limit Lower
Sets the low temperature alarm level. If ALC = rE it sets how
many degrees below Set Point. If ALC = Ab it sets a fixed alarm
temperature.
-50 c ÷ Set
Point
V- 50 c
Ald Alarm Delay Sets the time delay between a temperature alarm condition being
sensed and the alarm being signaled during normal operation.
0 ÷ 255 mins.
H15 mins.
