HOW TO SEE AND MODIFY THE SET POINT (TEMPERATURE AND HUMIDITY)
1.
Push and immediately release the SET key: the display will show the Set point
valueand the correspondant set icon starts flashing;
2.
To change the Set value push the
o
or
n
arrows within 10s.
3.
To memorise the new set point value push the SET key again or wait 10s.
6.3
TO START A MANUAL DEFROST
1. Push
the
DOWN key for more than 2 seconds and a manual defrost will start.
6.4
TO ENTER IN PARAMETERS LIST “PR1”
To enter the parameter list “Pr1” (user accessible parameters) operate as follows:
+
1.
Enter the Programming mode by pressing the SET_RH+
n
for few
seconds. (LED2&3 start flashing)
2.
The instrument will show the first parameter present in “Pr1”
6.5
TO ENTER IN PARAMETERS LIST “PR2”
To access parameters in “Pr2”:
1.
Enter the “Pr1” level.
2.
Select “Pr2” parameter and press the “ SET_RH ” key.
3.
The “PAS” flashing message is displayed, shortly followed by “0 - -” with a flashing zero.
4.
Use
o
or
n
to input the security code in the flashing digit; confirm the figure by pressing “
SET_RH ”.
The security code is “321“.
5.
If the security code is correct the access to “Pr2” is enabled by pressing “ SET_RH ” on the last
digit.
Another possibility is the following: after switching ON the instrument the user can push SET_RH +
n
keys within 30 seconds.
NOTE: each parameter in “Pr2” can be removed or put into “Pr1” (user level) by pressing SET_RH +
n
. When a parameter is present in “Pr1” LED 4 is on.
6.6
TO CHANGE PARAMETER VALUES
1.
Enter the Programming mode.
2.
Select the required parameter with
o
or
n
.
3.
Press the “ SET_RH ” key to display its value (LED2&3 start blinking).
4.
Use
o
or
n
to change its value.
5.
Press “ SET_RH ” to store the new value and move to the following parameter.
To exit: Press SET_RH + UP or wait 15s without pressing a key.
NOTE: the new programming is stored even when the procedure is exited by waiting the time-out.
6.7
HOW TO LOCK THE KEYBOARD
1.
Keep the
o
and
n
keys pressed together for more than 3 s the
o
and
n
keys.
2.
The “POF” message will be displayed and the keyboard is locked. At this point it is
only possible the viewing of the set point or the MAX o Min temperature stored and
to switch ON and OFF the light, the auxiliary output and the instrument.
TO UNLOCK THE KEYBOARD
Keep the
o
and
n
keys pressed together for more than 3s.
6.8
ON/OFF FUNCTION
By pushing the ON/OFF key, the instrument shows “OFF” for 5 sec. and the ON/OFF
LED is switched ON.
During the OFF status, all the relays are switched OFF and the regulations are stopped;
N.B. During the OFF status the LED4 button is lighted.

PARAMETER LIST
REGULATION
dbt
half dead band width for temperature: (0,1÷25,5°C; 1÷45°F) this band is place below and
above the temperature set point (SET_TEMP). The compressor is enabled when the temperature
increases and reaches the SE dbt value. It is turned off when it comes back to the
SET_TEMP. The heating output is enabled when temperature is less than SET_TEMP -dbt value
and disabled when the SET_TEMP is reached.
dbH
half dead band width for humidity: (0,5÷25,5RH) this band is place below and above the
humidity set point (SET_RH). The dehumidifying action is enabled when the humidity increases
and reaches the dbH value. It is stopped when it comes back to the SET_RH. The
humidifying output is enabled when humidity is less than SET_RH -dbH value and disabled when
the SET_RH is reached.
LS Minimum temperature set point limit: (-50,0°C
÷
SET; -58°F÷SET) Sets the minimum
acceptable value for the set point.
US Maximum temperature set point limit: (SET
÷
110°C; SET÷230°F) Set the maximum acceptable
value for set point.
OdS Outputs activation delay at start up: (0÷255 min) This function is enabled at the initial start up
of the instrument and inhibits any output activation for the period of time set in the parameter.
(Light can work)
AC Anti-short cycle delay: (0÷30 min) interval between the compressor stop and the following
restart.
tHu Kind of de-humidifying: db: only with de-humidifier relay (oA1= dEH)
cHu with de-humidifier and compressor relay (oA1= dEH)
c-H: without de-humidifier relay, by means of compressor and heating relays (oA1
≠
dEH).
LSH Minimum humidity set point limit: (
Lci ÷ Set H
) Sets the minimum acceptable value for the
humidity set point.
USH Maximum humidity set point limit: (
Set H ÷ uci
) Set the maximum acceptable value for
humidity set point.
DISPLAY
CF Measurement unit: °C= Celsius; °F= Fahrenheit
rES Resolution (for °C): allows decimal point display. dE = 0,1°C; in = 1 °C
rEH Resolution for RH%: in = integer; Hd= half digit.
DEFROST
tdF Defrost type: rE = electrical heater (Compressor OFF)
in = hot gas (Compressor and defrost relays ON)
EdF Defrost mode: in = interval mode. The defrost starts when the time “Idf” is expired.
Sd = Smartfrost mode. The time IdF (interval between defrosts) is increased only when the
compressor is running (even non consecutively).
SdF Set point for SMARTFROST: (-30
÷
30 °C/ -22
÷
86 °F) evaporator temperature which allows the
IdF counting (interval between defrosts) in SMARTFROST mode.
dtE Defrost termination temperature: (-50,0÷110,0°C; -58÷230°F) (Enabled only when the
evaporator probe is present) sets the temperature measured by the evaporator probe which
causes the end of defrost.
IdF Interval between defrosts: (1÷120h) Determines the time interval between the beginning of two
defrost cycles.
MdF Duration of defrost: (0÷255 min) When P2P = n, no evaporator probe, it sets the defrost
duration, when P2P = y, defrost end based on temperature, it sets the maximum length for
defrost.
dFd Display during defrost: rt = real temperature; it = temperature reading at the defrost start;
Set = set point; dEF = “dEF” label; dEG = “dEG” label;
dAd Defrost display time out: (0
÷
255 min) Sets the maximum time between the end of defrost and
the restarting of the real room temperature display.
Fdt Drain down time: (0÷60 min.) time interval between reaching defrost termination temperature
and the restoring of the control’s normal operation. This time allows the evaporator to eliminate
water drops that might have formed due to defrost.
dPO First defrost after start-up: y = Immediately; n = after the IdF time
Hud Humidity control during defrost: no: the humidity control is stopped during the defrost; yES the
humidity control works also during the defrost.
FANS
FnC Fan operating mode: C-n = running when a load is on, OFF during the defrost;
C-y = running when a load is on, ON during the defrost;
O-n = continuous mode, OFF during the defrost; O-y = continuous mode, ON during the defrost;
TEMPERATURE ALARMS
ALC Temperature alarm configuration: rE = High and Low alarms related to Set Point
Ab = High and low alarms related to the absolute temperature.
ALL Low temperature alarm setting:
ALC = rE , 0
÷
50 °C or 90°F
