1.1 Important
Read these instructions carefully before installation and commissioning and follow all recommendations for installation and for the electric
connection; keep these instructions with the instrument for future consultation.
The instrument must be disposed of according to local Standards regarding electric and electronic appliances.
2 DIMENSIONS AND INSTALLATION
2.1 Dimensions and installation
Dimensions in mm (in); back-panel installation using M3 studs.
The diagram illustrates the model with the greatest supply of hardware.
2.2 Recommendations for installation
• make sure that the working conditions (temperature of use, humidity, etc.) lie within the limits indicated in the technical data
• do not install the instrument in proximity of heat sources (heaters, hot air pipes etc.) appliances withe strong magnets (large diffusers etc.), places
subject to direct sunlight, rain, humidity, excessive dust, mechanical vibrations or shocks
• in compliance with Safety Standards, the protection against any contact with the electric parts must be ensured via correct installation of the
instrument. All parts that ensure protection must be fixed in a way such that they cannot be removed without the aid of a tool.
3 ELECTRIC CONNECTION
3.1 Electric connection
The diagram illustrates the model with the greatest supply of hardware.
3.2 Recommendations for installation
• do not operate on the terminal boards using electric or pneumatic
screwdrivers
• if the instrument has been taken from a old place to a hot one, the
humidity could condense inside. Wait about one hour before
applying power
• make sure that the power supply voltage, frequency and operational
electric power correspond to those of the local power supply
• disconnect the power supply before performing any type of
maintenance
• equip the probes with a protection able to insulate them against any
contact with metal parts or use isolated probes
• do not use the instrument as a safety device
• for repairs and information regarding the instrument, contact the
Evco sales network.

4.2 Management of the utilities
Temperature regulation.
The output activity depends mainly on the temperature of the
chamber, the work set point and the parameter P5.
Top.
If functioning with 1 measurement input (parameter P3 = 1):
• the out put is measured in a cyclical mode, preferably when the floor
output is off (the parameter P10 establishes the cycle time. Using the
procedure given in paragraph 6.2.1 it is possible to set the duration
of output switch-on, intended as a percentage of the time established
with the parameter P10)
• the cyclical activation is subordinate to the temperature of the
chamber (chamber probe), at the work set point and parameter P4.
If functioning with 2 measurement inputs (parameter P3 = 0):
• the output activity will mainly depend on the temperature of the top
(top probe), the top set point and the parameter P4.
Floor.
If functioning with 1 measurement input (parameter P3 = 1):
• the out put is measured in a cyclical mode, preferably when the top
output is off (the parameter P10 establishes the cycle time. Using the
procedure given in paragraph 6.2.2 it is possible to set the duration
of output switch-on, intended as a percentage of the time established
with the parameter P10)
• the cyclical activation is subordinate to the temperature of the
chamber (chamber probe), at the work set point and parameter P4.
If functioning with 2 measurement inputs (parameter P3 = 0):
• the output activity will mainly depend on the temperature of the
floor (floor probe), the floor set point and the parameter P4.
Timer 1.
The output is on continuously during the count of the time P0.
Timer 2.
The output is on continuously during the count of the time P6.
Acoustics.
The output is on continuously on the conclusion of the count of
the cooking timer.
Auxiliary.
The activity of the output depends mainly on parameters P6 and P7.

USER INTERFACE
5.1 Preliminary considerations
The diagram illustrates the model with the greatest supply of hardware.
For all models.
The following functioning states exist:
• the “on” status (the instrument is powered and “on”: the regulators
can be switched on)
• the “stand-by” status (the instrument is powered but is “off” via software:
the regulators are off
• the “off” state (the instrument “is not powered”).
Successively, the term “switch-on” means that the passage from the
stand-by status to the on status; the term “switch-off” means the passage
from the on status to the stand-by status.
When the instrument is powered it re-proposes the status in which it
found itself at the time when the power supply was disconnected.
If there is a power cut during a time count, the count will start again
from the beginning when the power supply is restored.
