1. GENERAL WARNING

1.1 PLEASE READ BEFORE USING THIS MANUAL

• This manual is part of the product and should be kept near the instrument for easy and

quick reference.

• The instrument shall not be used for purposes different from those described hereunder. It

cannot be used as a safety device.

• Check the application limits before proceeding.

1.2

SAFETY PRECAUTIONS

• Check the supply voltage is correct before connecting the instrument.

• Do not expose to water or moisture: use the controller only within the operating limits

avoiding sudden temperature changes with high atmospheric humidity to prevent formation

of condensation

• Warning: disconnect all electrical connections before any kind of maintenance.

• Fit the probe where it is not accessible by the End User. The instrument must not be

opened.

• In case of failure or faulty operation send the instrument back to the distributor

with a

detailed description of the fault.

• Consider the maximum current which can be applied to each relay (see Technical Data).

• Ensure that the wires for probes, loads and the power supply are separated and far enough

from each other, without crossing or intertwining.

• In case of applications in industrial environments, the use of mains filters (our mod. FT1) in

parallel with inductive loads could be useful.

2. GENERAL DESCRIPTION

Model 30 format 32 x 74 mm, is a digital thermostat with off cycle defrost designed for

refrigeration applications at normal temperature. It provides two relay outputs, one for the

compressor, the other one can be used as light, for alarm signalling or as auxiliary output.. It is

also provided with 1 or 2 NTC probe inputs the first one for temperature control, the second one,

optional, to connect to the HOT KEY terminals to signal the condenser temperature alarm or to

display a temperature. The digital input can operate as third temperature probe.

The HOT KEY output allows to connect the unit, by means of an external module, to a network

line compatible.

It allows to program the controller by means the HOT KEY programming keyboard.

The instrument is fully configurable through special parameters that can be easily programmed

through the keyboard.

3. CONTROLLING LOADS

3.1 COMPRESSOR

The regulation is performed

according to the temperature

measured by the thermostat probe

with a positive differential from the

set point: if the temperature

increases and reaches set point plus

differential the compressor is started

and then turned off when the

temperature reaches the set point

value again.

Time

Temper.

Compr.

SET

In case of fault in the thermostat probe the start and stop of the compressor are timed through

parameters “COn” and “COF”.

3.2 DEFROST

Defrost is performed through a simple stop of the compressor. Parameter “IdF” controls the

interval between defrost cycles, while its length is controlled by parameter “MdF”.

4. FRONT PANEL COMMANDS

: To display target set point; in programming mode it selects a parameter or confirm an

operation.

(DEF) To start a manual defrost

(UP): To see the max. stored temperature; in programming mode it browses the parameter

codes or increases the displayed value.

(DOWN) To see the min stored temperature; in programming mode it browses the

parameter codes or decreases the displayed value.

O/I To turn ON or OFF the controller (if enabled)

KEY COMBINATIONS:

To lock & unlock the keyboard.

+ To enter in programming mode.

+ ! To return to the room temperature display.

4.1 CONTROL OF EVAPORATOR FANS

The fan control mode is selected by means of the “FnC” parameter:

FnC = C_n: fans will switch ON and OFF with the compressor and not run during defrost;

FnC = o_n fans will run even if the compressor is off, and not run during defrost;

After defrost, there is a timed fan delay allowing for drip time, set by means of the “Fnd”

parameter.

FnC = C_Y fans will switch ON and OFF with the compressor and run during defrost;

FnC = o_Y fans will run continuously also during defrost

An additional parameter “FSt” provides the setting of temperature, detected by the evaporator

probe, above which the fans are always OFF. This is used to make sure circulation of air only if

his temperature is lower than set in “FSt”.

4.1.1 Cyclical activation of the fans with compressor off.

When Fnc = c-n or c-Y (fans in parallel to the compressor), by means of the Fon and FoF

parameters the fans can carry out on and off cycles even if the compressor is switched off. When

the compressor is stopped the fans go on working for the Fon time. With Fon =0 the fans remain

always off, when the compressor is off. This increases humidity in the system.

4.2 USE OF LEDS

Each LED function is described in the following table.

5. MAX & MIN TEMPERATURE MEMORIZATION

5.1 HOW TO SEE THE MIN TEMPERATURE

1. Press and release the n key.

2. The “Lo” message will be displayed followed by the minimum temperature recorded.

3. By pressing the n key again or by waiting 5s the normal display will be restored.
