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”

icon is on.

8.7 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 (°C or °F icon 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.

8.8 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.

8.9 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

icon is lighted.

9. 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 SET TEMP + 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 SET %RH + 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 AND KIND OF REGULATION

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.

trC Kind of behaviour after the end of the cycle

trC=co the controller goes on working, and maintains the temperature and humidity of the running phase, till the controller is stopped.

trC=in at the end of the stopping phase the controller gives the “End” message, the buzzer is turned on, and the regulation is stopped.

trC=cL at the end of the stopping phase the controller gives the “End” message, the buzzer is turned on, and the regulation restarts from

the running phase
