ARAMETER DESCRIPTION
36.1
Regulation Parameters
ST01
Setpoint in Chiller mode(range ST05..ST06).
ST02
Differential of the Chiller mode.
ST03
Setpoint in Heat Pump mode (range
ST07..ST08)
ST04
Differential of the Heat Pump mode.
ST05
Minimum limit value of ST01 settable for Chiller
mode (range -40°C / °F…ST01).
ST06
Maximum limit value of ST01 settable for Chiller
mode (range ST01…110 °C / 230°F).
ST07
Minimum limit value of ST03 settable for Heat
Pump mode ( range –40°C / °F...ST03).

Configuration parameters
CF01
configure the type of the unit.
Based on this
parameter some parameters can be hidden. (see the
table - menu)
Type of unit:
0= Chiller air / air
1= Chiller air / air with heat pump
2= Chiller air / water
3= Chiller air / water with heat pump
4= Chiller water / water
5= Chiller water / water with heat pump
CF02
Motocondensing Unit
0= Yes; 1= No
CF03 R
egulation probe
0= Pb1 probe control; 1= Pb2 probe
control
CF04
Pb1 analogue input configuration:
0 = No Probe
1 = NTC probe for evaporator water inlet / controlled
air showed on the upper display.
2 = Digital input for Motocondensing unit.
When the contact is not active the unit turns to stand-
by, upper display shows OFF.
The active input turns the unit in stand-by but the
upper display shows ON.
In this situation using
o
and
n
keys is possible to start
the functioning in Chiller or Heat Pump mode:
in Chiller mode the upper display shows OnC. If
CF21=2 and CO08=1 the 1
st
compressor starts, with
CF21=2 and CO08=0 the compressor with less
counted hours starts.
in Heat Pump mode the upper display shows OnH.:
with CF21=2 and CO08=1 the 1
st
compressor starts,
with CF21=2 and CO08=0 the compressor with less
counted hours starts.
If the digital input becomes not active and then active
again the unit stops and then restarts with the
selected mode. Only with active input is possible to
change the functioning again through
o
and
n
keys.
3 = Digital input for motocondensing unit. It turns the
unit on only in Chiller mode, the upper display shows
OnC. If the contact is not active the unit turns to
stand-by and the display shows OFF. Only with active
contact, if the unit has been turned off through
o
and
n
keys, is possible to turn it on again through
o
and
n
keys.
CF05
Pb2 input configuration
0 = no Probe
1 = NTC probe temperature “evaporator water outlet”/
“evaporator out air”, it is showed on the upper display.
2 = Digital input to generate the anti-freeze alarm,
check the polarity.
3 = Digital input for motocondensing. If active it starts
the unit in Heat Pump, the upper display shows OnH.
While, if not active, the unit is in stand-by, the upper
display shows OFF. Only if this input is active is
possible to turn Off and On the unit through
o
and
n
keys.
CF06
Pb3 input configuration
0 = no Probe
1 = NTC temperature probe to control the condenser
fan speed, it is showed on the lower display.
2 = 4..20mA condensing pressure input to control the
condenser fan speed, it is showed on the lower
display.
3 = 4..20mA Dynamic Setpoint input signal decided by
the user.
4 = NTC condenser probe anti-freeze alarm
(water/water or water/water with Heat Pump) , it is
showed on the lower display.
CF07
Pb4 input configuration
0 = no Probe
1 = NTC temperature probe to control the condenser
fan speed, it is showed on the lower display.
2 = Configurable digital input.
3 = NTC probe for outdoor air control. It works for:
Dynamic Setpoint, Boiler and Auto Change–over.
4 = NTC probe for condenser anti-freeze alarm
(water/ water or water/water with Heat Pump), It is
showed on the lower display.
5= NTC probe to detect the evaporator temperature in
Heat Pump and control the Combined Defrost. It
determines the defrost start and stop.
6= NTC probe used only for the data logger function.
