tion and adjustment that the device's use requires. The functions of the front part keys as well
as the display of temperatures can be modified, while the configuration with a password can
be blocked.

Examples of some of the many applications

Heat:
Thermostat with two probes to display and
control.
Thermostat with control relay and alarm relay.
Action thermostat by a temperature difference
between the two probes.
As two simple thermostats.
As two cyclic timing devices without enabling
the probes.

Double insulation between the power supply, the secondary circuit and the relay output.
* The current specified for each relay is its individual maximum. When more than one relay is
connected, the total current cannot surpass 17,5A (EN61010) or 13A (EN60730).
3 - INSTALLATION
The controller must be installed in a place protected from vibrations, water and corrosive gases,
and where the ambient temperature does not surpass the values specified in the technical data.
In order for the panel mounting units to be suitable having IP65 protection, the gasket should
be installed properly between the apparatus and the perimeter of the panel cut-out where it is
to be fitted.
In order to give a correct reading, the probe has to be installed in a place without heat influen-
ces other than the temperature that is to be measured or controlled.
3.1 Fastening units for panel mounting:

3.2 Fastening units for DIN rail mounting:
3.3 Connection:
See diagram in the unit rating plate.
The probe and its lead shoud NEVER be installed in ducting along with power, control or power
supply wiring.
The power supply circuit should be connected with a minimum 2A, 230V, switch located close
to the unit. The cables should be of the type H05VV-F 2x0,5mm
Section of connecting wires for relays contacts must be between 1mm
Edición 01
The two probe inputs can be inte-
rrelated with the two relay outputs
for the thermometer, thermostat
and the timing functions in cold and
heat applications.

UP key (factory default)
By pressing this key, the temperature in probe 2 is displayed.
By pressing it during 5 seconds, the R2 SET POINT is displayed.
In programming, it increases the value being displayed.
UP key (configurable)
By default, the configuration of this key is factory-set for the preceding actions. However,
it can be configured according to the options of parameters 42, 43.
DOWN key (factory default)
By pressing this key during 5 seconds, the R1 SET POINT is displayed.
In programming, it decreases the value being displayed.
DOWN key (configurable)
By default, the configuration of this key is factory-set for the preceding functions.
However, it can be configured according to the options of parameters 44, 45.

CONFIGURATION: It should only be programmed or modified by personnel who are fully con-
versant with the operation and possibilities of the equipment.
Level 1
Parameters
- Press the CONFIGURE OR ADJUST keys for 10 seconds. The LED "ºC" will be flashing to
indicate programming phase and the first parameter "01" will appear on the display.
- Pressing the ( key accesses the next parameter and the ( key will produce a return to
the previous one.
- Pressing DISPLAY VALUE key in the last display EP the controller will return to the current
temperature display status and the LED "ºC" will stop flashing.
Level 2
Values
- In order to display the current value of any parameter, select the desired parameter and
press the DISPLAY VALUE keys. Once it is displayed, it can be modified by pressing the
( or ( keys
- Pressing the ACCEPT THE NEW keys sets the new value. When this operation is performed,
the programming returns to Level 1 (parameters).

ADJUSTMENT: Pressing once the CONFIGURE OR ADJUST keys accesses the user's para-
meters adjustment. The proceeding is the same as for the configuration and access is only
possible to the parameters defined as adjustable by the user in the configuration. In order to
access the parameters the parameter 39 parameter should be configured.
REMARK: If no key is pressed for 25 seconds in any of the previous steps, the controller will
automatically return to the current temperature display status without modifying any of the
