AT1-5 INSTRUCTIONS FOR USE
Risk of Fire or Electric Shock
WARNING
■ Disconnect power at the circuit breaker(s) or disconnect switch(es) before installing or servicing.
■ More than one circuit breaker or disconnect switch may be required to de-energize the equipment before servicing.
■ Installation and/or wiring must be in accordance with National and Local Electrical Code requirements.
■ The device shall be installed in compliance with the enclosure, mounting, spacing and segregation requirements of the ultimate enclosure.
Thank you for having chosen an Intermatic electronic product. Before installing the instrument, please read these instructions carefully to
ensure maximum performance and safety.

INSTALLATION
■ Insert the controller through a hole measuring 71 mm x 29 mm.
■ Make sure that electrical connections comply with the paragraph "wiring diagrams". To reduce the effects of electromagnetic disturbance,
keep the sensor and signal cables well separate from the power wires.
■ Fix the controller to the panel by means of the suitable clips, by pressingly gently; if fitted, check that the rubber gasket adheres to the
panel perfectly, in order to prevent debris and moisture infiltration to the back of the instrument.
■ Place the probe T1 inside the room in a point that truly represents the temperature of the stored product.
■ Place the probe T2 on the evaporator where there is the maximum formation of frost.
OPERATION
DISPLAY
During normal operation, the display shows either the temperature measured or one of the following indications:
DEF Defrost in progress HI Room high temperature alarm
REC Recovery after defrost LO Room low temperature alarm
OFF Controller in stand-by E1 Probe T1 failure
CL Condenser clean warning E2 Probe T2 failure
DO Door open alarm
INFO MENU
The information available in this menu is:
T1 Instant probe 1 temperature TLO Minimum probe 1 temperature recorded
T2 Instant probe 2 temperature CND Compressor working weeks
THI Maximum probe 1 temperature recorded LOC Keypad state lock
Access to menu and information displayed.
■ Press and immediately release button .
■ With button or select the data to be displayed.
■ Press button to display value.
■ To exit from the menu, press button or wait for 10 seconds.
Reset of THI, TLO, CND recordings
■ With button or select the data to be reset.
■ Display the value with button .
■ While keeping button pressed, use button .
SETPOINT (display and modifi cation of desired temperature value)
■ Press button for at least half second, to display the setpoint value.
■ By keeping button pressed, use button or to set the desired value (adjustment is within the minimum SPL and the maximum
SPH limit).
■ When button is released, the new value is stored.
STAND-BY
Button , when pressed for 3 seconds, allows the controller to be put on a standby or output control to be resumed (with SB=YES only).
KEYPAD LOCK
The keypad lock avoids undesired, potentially dangerous operations, which might be attempted when the controllers is operating in a public
place. In the INFO menu, set parameter LOC=YES to inhibit all functions of the buttons. To resume normal operation of keypad, adjust setting
so that LOC=NO.
DEFROST
Timed defrost. Defrosting starts automatically when necessary time has elapsed to obtain the defrosting frequency set with DFR. For
example, with DFR=4 defrosting occurs once every 6 hours. The internal timer is set to zero when power is applied to the controller and at
each subsequent defrost start. When the controller is put on a standby, the accumulated time count is "frozen" (is not incremented).
Manual defrost. Defrosting may also be induced manually by keeping the button pressed for 2 seconds.
Defrost type. Once defrost has started, Compressor and Defrost outputs are controlled according to the parameters DTY and OAU. The AUX
output is associated to defrost function with OAU=DEF exclusively.
Defrost termination. Defrost lasts as long as time DTO but, if the evaporator probe has been enabled (T2=YES) and temperature DLI is
achieved before this time elapses, defrost will be terminated in advance. Caution: if C-H=HEA all defrost functions are inhibited; if DFR=0
the timed defrost function is excluded; during defrost, the high temperature alarm is inhibited.
CONFIGURATION PARAMETERS
■ The setup menu is accessed by pressing button + for 5 seconds.
■ With button or select the parameter to be modified.
■ Press button to display the value.
■ By keeping button pressed, use button or to set the desired value.
■ When button is released, the newly programmed value is stored and the following parameter is displayed.
■ To exit from the setup, press button or wait for 30 seconds.
PAR RANGE DESCRIPTION
SCL 1°C; Readout scale.
2°C; 1°C (only with INP=SN4): measuring range -50/-9.9 ... 19.9/80°C
°F 2°C : measuring range -50 ... 120°C
°F : measuring range -55 ... 240°F
Caution: upon changing the SCL value, it is then absolutely necessary to reconfigure the parameters relevant
to the absolute and relative temperatures (SPL, SPH, SP, ALA, AHA, etc..)
SPL -50..SPH Minimum limit for SP setting (-5°C)
SPH SPL.120° Maximum limit for SP setting (5°C)
SP SPL... SPH Setpoint (value to be maintained in the room). (0.0°C)

switchover. We recommend to set CRT=03 with HYS<2.0°. (3)
CT1 0...30min Thermostat output run when probe T1 is faulty. With CT1=0 the output will always remain OFF. (3)
CT2 0...30min Thermostat output stop when probe T1 is faulty. With CT2=0 and CT1>0 the output will always be ON.
Example: CT1=4, CT2= 6: In case of probe T1 failure, the compressor will cycle 4 minutes ON and 6 minutes
OFF. (6)
CSD 0..30min Compressor stop delay after the door has been opened (active only if DS=YES). (1)
DFR 0... 24(1/24h) Defrost frequency expressed in cycles/24 hours. (3)
DLI -50...120° Defrost end temperature. (6°C)
DTO 1...120min Maximum defrost duration. (20)

ELE; OFF: off cycle defrost (Compressor and Heater OFF).
GAS ELE: electric defrost* (Compressor OFF and Heater ON).
GAS: hot gas defrost* (Compressor and Heater ON).
* The defrost output is active if only OAU=DEF.
DDY 0...60min Display during defrost. If DDY=0 during defrost the temperature continues to be displayed. If DDY > 0, during
defrost the display shows DEF, when defrost is over REC is displayed during DDY minutes. (10)
ATM NON; Alarm threshold management.
ABS; NON: all temperature alarms are inhibited (the following parameter will be ADO).
REL ABS: the values programmed in ALA and AHA represent the real alarm thresholds.
