■ During the installation and operation of the instrument, follow the

instructions set out below:

1) The instrument should be installed by a skilled operator.

2) Strictly follow the connection diagrams when installing the instrument.

3) Do not power or connect the instrument if any part of it is damaged.

4) Before touching the terminals, make sure the wires to be connected to

the instrument are not live.

5) The connection cables should be able to resist the maximum operating

temperature (Tmax), obtained from the sum of the maximum ambient

temperature (Ta) + a temperature of 20 °C (Tmax= Ta + 20 °C).

6) The instruments guarantee a main insulation between the low voltage

(250 V) and very low voltage parts.

7) Any outside switches connected to the controls should guarantee a

minimum insulation at operating temperature of 250 V AC, or should be

protected by equivalent insulation.

8) Contacts: all type 1C (CEI 107-70 and variants).

9) The instruments require no maintenance.

■Series of digital regulators used for the most simple requirements in the control

and regulation of humidity and pressure levels in air conditioning, heating

and refrigeration systems

■Two dedicated base models for pressure and humidity control:

- DIGITAL HUMIDITY REGULATORS HR

- DIGITAL PRESSURE REGULATORS PR

■Each single model has 1 probe input for the connection of active sensors

with standardised 0÷20 mA, 4÷20 mA and 0÷1 V outputs

■The power supply to the active probe (linear sensor) comes directly from

the instrument: 9 V DC available

• For each single model, the probe input can be configured from the keyboard

• Available in versions with 1 or 2 relay outputs with contact in exchange

• Regulators with 3 digit, seven segment and decimal point display

• Relay intervention warning lamp

• Display range: -99 ÷ +999

• Display resolution: 0.1 RH or bar (-9.9 ÷ +99.9 RH or bar)

and 1 RH or bar (< -9.9 °C and > +99.9 RH or bar)

• Precision: ±0.5 % of the end of scale value ±1 digit

(at an ambient temperature of 23 °C)

• Sampling time: 0.5s
