6 PARAMETERS AND ALARMS
6.1 Restore default parameters
To restore default parameters press the POWER key for 5 seconds during the modify parameter mode. Setting
defaults (including environment set point if Pr01=0, humidity set point and offset night) will be confi rmed with
the simultaneous display of “Def” “Yes”.
At the end the modify parameters mode will exit automatically. This procedure does not modify the time
periods previously set by means of the CLOCK key. The communication of the µChiller is re-started.
6.2 Editing parameters
To confi gure the parameters, proceed in the following manner:
• Press and release the TEMP key, then press and hold the UP key for 3 seconds.
• Choose the parameter to be modifi ed using the UP and DOWN keys.
• Select the parameter by pressing the TEMP key and then modify it by pressing the UP and DOWN keys.
• Exit saving the settings by holding the TEMP key for 5 seconds or if the modifi cations are not to be saved,
wait 1 minute before pressing any key.
6.3 Parameters
Ad01: µChiller address
Informs the µAD at which supervisor network address the µChiller is present. Range: 1...200, default: 1 (corre-
sponding to the default confi guration of the µC
2 SE)
Co01: Compensation mode
If set at “1”, the µChiller set point adjustment set point compensation mode is activated (see paragraph 5.10).
Value Description
0 Deactivates the compensation mode (default)
1 Activates the compensation mode
Co01 is only used when µAD is connected to µC 2 SE
Co02: Compensation in cooling
Informs the µAD of the maximum value of the differential for compensation in cooling mode (see5.10).
Range: 1..20 °C/°F, default: 2.
Co02 is only used when µAD is connected to µC
2 SE.
Co03: Compensation in heating
Informs the µAD of the maximum value of the differential for compensation in heating mode (see 5.10).
Range: 1..20 °C/°F, default: 2.
Co03 s only used when µAD is connected to µC
2
SE

2 Activates the buzzer when the keys are pressed or in the case
of alarm.
En03: HUM key function (Fig. 2.a)
Allows to select the function associated to key 3.
Value Description
0 Setting the humidity set point (default)
1 Setting FAN mode (only for µC 2 SE)
En04: Manual de-humidifi cation mode.
Disables selection of manual de-humidifi cation by means of the MODE key.
