4. Attach the humidistat to the base, at first mating teeth on the higher side.

OPERATION

During the standard operation humidistat displays the detected humidity value and the relay status is identified by the symbol switching on.
Setpoint modification

Depleted batteries signal

Replace the batteries as soon as possible!
** Dispose of the batteries in the appropriate recycling containers.
Advanced programming
Possible operations:**

• Limit the upper and lower settable range of the set point values
• Set a password to lock the keyboard (useful to prevent changes by unauthorized persons)

• Display of the various menu items in automatic succession after 3 seconds without any key pressure
• Use the ▲ and ▼ keys to modify the displayed parameter values
• When programming is finished, the message , is displayed, the humidistat returns to normal operation, saving the changes made

| Minimum settable setpoint –
It’s the minimum value settable as setpoint.
Settable values: 30% RH ÷
---|---
| Maximum settable setpoint –
It’s the maximum value settable as setpoint.
Settable values: ÷ 90% RH
| Correction of humidity measurement % RH –
Possibility to enter a humidity compensation value.
Available range from -10% RH to + 10% RH.
Resolution 1% RH
| Password for keypad lock –
Set a value between 001 and 999 to activate the keypad lock. Set “—” to disable the lock.
