• Upstream of the electrical connection, an efficient disconnection system must be provided and it must be identified
• The air conditioner is already fitted with a temperature controller, no additional temperature control must be connected upstream of the unit.

Insert signal connector (included in installation kit, refer to picture below) inside of 4 poles female connector placed on the back of the air conditioner.

ALARM OUTPUT / DIGITAL INPUT
Air conditioner is fitted with an electronic controller which permits alarm output and digital input signals.

• Alarm output
  Alarm output is activated according to alarm parameters (for example in case of enclosure temperature higher than ALU value, digital input not activated… See PARAMETERS at 4.2 DIGITAL THERMOSTAT INSTRUCTION section) Alarm output is a potential-free contact.

• Digital input

  • WARNING: proper functions of the air conditioner are allowed only if digital input is activated. (closed contact between poles 13-14).
  • Digital input can be a door limit switch or a generic external clean contact.

Plug for signals is factory wired with a bridge between 13-14 poles. The bridge can be removed to wire, for example, a door limit switch.

STARTING AND ADJUSTMENT

• After finishing the assembly of the conditioner, wait approx. 30 min. before starting it (the oil must collect in the compressor to ensure lubrication and cooling).
• The air conditioner operates automatically, that is to say, after insertion, the evaporator fan operates continuously making the air inside the cabinet circulate. This way a uniform distribution of temperature inside the cabinet itself is attained. The built-in thermostat drives the compressor and condenser fan according to the set point value.
• Compressor turns and condenser fan ON when internal enclosure temperature rises to set point value + hysteresis.
• The compressor and condenser fan turn OFF when the internal enclosure temperature decreases below the set point value.

DIGITAL THERMOSTAT INSTRUCTION

WARNING:
the air conditioner is designed to operate at 35 ° C cabinet temperature. If the set point is changed the performance of the unit will vary.

1. A regulating thermostat is a fixed air conditioner cover.

2. The thermostat could be set into a range from 20°C up to 50°C. Follow thermostat instructions for parameter changing.

3. Factory parameters are specially set for the proper unit functionality, it is not suggested to change them.
   Setting parameters are divided into two menus: the main menu and the hidden menu.

   • WARNING: Some parameters collected in HIDDEN MENU are not needed for air conditioner operation, do not modify them.

MAIN MENU PARAMETERS

• Hy Differential: (0,1 ÷ 25,5°C / 1÷255 °F) Intervention differential for set point.
  Compressor Cut IN is Set Point + differential (Hy). Compressor Cut OUT is when the temperature reaches the set point.

• Ot Thermostat probe calibration: (-12.0÷12.0°C; -120÷120°F) allows for adjustment of possible offset of the thermostat probe.

• AC Anti-short cycle delay: (0÷50 min) minimum interval between the compressor stop and the following restart.

• CH Type of action: CL = cooling; Ht = heating. (do not change this parameter)

• rES Resolution (for °C): (in = 1°C; dE = 0.1 °C) allows decimal point display.

• dLy Display delay: (0 ÷20.0m; result. 10s) When the temperature increases, the display is updated of 1 °C/1°F after this time.

• IdF Interval between defrost cycles: (0÷120h) Determines the time interval between the beginning of two defrost cycles. (the air conditioner is not equipped with defrost, do not change this parameter)

• MdF (Maximum) length for defrost: (0÷255min) (0=no defrost) When P2P = n, (not evaporator probe: timed defrost) it sets the defrost duration, when P2P = y (defrost end based on temperature) it sets the maximum length for defrost. (the air conditioner is not equipped with defrost, do not change this parameter)

• ALU MAXIMUM temperature alarm: (SET÷110°C; SET÷230°F) When this temperature is reached the alarm is enabled, after the “ALd” delay time.

• ALL Minimum temperature alarm: (-50.0 ÷ SET°C; -58÷230°F When this temperature is reached the alarm is enabled, after the “Ald” delay time.

• I1P Digital input polarity: oP: the digital input is activated by opening the contact; CL: the digital input is activated by closing the contact.

• I1F Digital input configuration: EAL = external alarm: “EA” message is displayed; bAL = serious alarm “CA” message is displayed. PAL = pressure switch alarm, “CA” message is displayed; dor = door switch function; dEF = activation of a defrost cycle; AUS =to switch on the second relay if oA1 = AUS; Htr = kind of action inversion (cooling-heating); Fan = not set it; ES = Energy saving.

• Did (0 ÷ 255 min) with i1F= EAL or i1F = bAL digital input alarm delay: delay between the detection of the external alarm condition and its signaling. With i1F= dor: door open signaling delay with i1F = PAL: time for pressure switch function: time interval to calculate the number of the pressure switch activations.

• PbC Type of probe: it allows to set of the kind of probe used by the instrument: PbC = PBC probe, ntc = NTC probe. (the air conditioner is fitted with an NTC probe, do not change this parameter)

Door switch input (i1f = dor)

• It signals the door status and the corresponding relay output status through the odc parameter:
• no= normal (any change);, Fan= fan OFF; CPr= Compressor OFF, F_C= Compressor and fan OFF.

Since the door is opened, after the delay time set through parameter did, the door alarm is enabled, the display shows the message dA and the regulation restarts is rtr = yES. The alarm stops as soon as the external digital input is disabled again. With the door open, the high and low-temperature alarms are disabled.

Digital inputs polarity
The digital input polarity depends on the i1P parameter.

• I1P=CL: the input is activated by closing the contact.
• I1P=OP: the input is activated by opening the contact

GENERIC ALARM (i1F = EAL)

• As soon as the alarm input is activated (for example enclosure temperature higher than the ALU value) the unit will wait for did time delay before signaling the EAL alarm message.
• The output status doesn’t change. The alarm stops just after the alarm input is deactivated.

SERIOUS ALARM MODE (i1F = bAL)
When the alarm input is activated (for example enclosure temperature higher than the ALU value), the unit will wait for did delay before signaling the CA alarm message. The relay outputs are switched OFF. The alarm will stop as soon as the alarm input is de-activated.
