1.1

Important

Read these instructions carefully before installation and use and fol-
low all recommendations regarding installation and for the electric
connection; keep these instructions for future reference.

The instrument must be disposed of according to local
Standards regarding the collection of electric and elec-
tronic appliances.

Installation recommendations:
• the thickness of the panel must not exceed 10.0 mm

(0.393 in)

• position the brackets as indicated in the drawing in this paragraph;

moderate the coupling torque

• make sure that the work 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 (resistances,

hot air pipes etc.) appliances with 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 installa-
tion 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.

1.3

Electric connection

With reference to the wiring diagram: the serial port for communica-
tion with the programming key.

Recommendations for the electric connection:
• do not operate on the terminal boards using electric or pneumatic

screwdrivers

• if the instrument has been taken from a cold place to a hot one, the

humidity could condense inside. Wait about one hour before ap-
plying power

• make sure that the power supply voltage, frequency and opera-

tional electric power correspond to those of the local power supply

• disconnect the power supply before performing any type of main-

tenance

• 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.

PRELIMINARY CONSIDERATIONS

2.1

Preliminary considerations

It is possible to set the work temperature of the top independently from
that of the floor.
The utilities managed by the digital outputs (i.e. the K1 relays... K6) are
the following:

RELAY MANAGED UTILITY

top

floor

steam injection

airhole

on/stand-by

chamber light

2.2

Management of the utilities

Top.
The output activity will mainly depend on the temperature of the top
(top probe), the top setpoint and the parameter r0.
Floor.
The output activity will mainly depend on the temperature of the floor
(floor probe), the floor setpoint and the parameter r6.
Steam injection.
The activity of the output depends mainly on the parameters t0, t1 and t2.
Airhole.
The output is activated in the following conditions:
• before the conclusion of the cooking timer count (the time estab-

lished with parameter c5), for the time established with parameter c6

• in manual mode, for the time established with the parameter c7.
On/Stand-by.
The output is activated during the “on” state (see paragraph 3.1).
Chamber light.
The output is activated in manual mode.

USER INTERFACE

3.1

Preliminary considerations

The following functioning states exist:
• “on” state (the instrument is powered and on: the regulators can be

switched on)

• “stand-by” state (the instrument is powered but switched off via soft-

ware: the regulators are off and programmed switch-on of the in-
strument is not envisioned)

• “programmed switch-on” state (the instrument is powered but

switched off via software: the regulators are off and programmed
switch-on of the instrument is envisioned)

• “off” state (the instrument is not powered).
Successively, the term “switch-on” means that the passage from the
stand-by state to the on state; the term “switch-off” means the passage
from the on state to the stand-by state.
When the instrument is powered it re-proposes the state in which it
found itself at the time when the power supply was disconnected.
3.2

Selecting the functioning state

To pass from the on state to the stand-by state (and vice versa):
• make sure that no procedure is in progress
• press

for 1s.

To pass from the on state to the programmed switch-on state:
• make sure that no procedure is in progress
• press

and

for 1s.

To pass from the programmed switch-on state to the on state:
• make sure that no procedure is in progress
• press

for 1s.

To pass from the stand-by state to the programmed switch-on state
(and vice versa):
• make sure that no procedure is in progress
• press

and

for 1s.

3.3

The display

If the instrument is in the on state:
• the highest display will show the quantity established with param-

eter P5:

- if P5 = 0, the display will show the top temperature
- if P5 = 1, the display will show the top setpoint (in this case, the

decimal point of the digit to the far right will be on)

• the central display will show the quantity established with param-

eter P6:

- if P6 = 0, the display will show the floor temperature
- if P6 = 1, the display will show the floor setpoint (in this case, the

decimal point of the digit to the far right will be on)

• the lowest display will show the quantity established with parameter P7:
- if P7 = 0, the display will show the value of the cooking timer or its

countdown if the timer is active (in this case the “timer” LED will be
on); the value of the cooking timer will be displayed in the
hour:minutes format

- if P7 = 1, the display will show the real time (in this case the “clock”

LED will be on); the real time is displayed in the 24h format
(hours:minutes).

See also paragraphs 3.5, 3.7 and 3.9
If the instrument is in the programmed switch-on state:
• the highest display will be off
• the central display will show the day of the next switch-on; the day

is visualised in 1 ... 7 format (number 1 corresponds to Monday; if
no switch-on is programmed, the central display will show “- - -”)

• the lowest display will show the time of the next switch-on; the time

is displayed in the 24h format (hours:minutes; if no switch-on is
programmed, the lowest display will show “- - - -”)

• the “delay” LED will be on
• the LED will be on.
If the instrument is in the stand-by state:
• the highest display will be off
• the central display and the lowest one:
- will be off if parameter c8 is set at 0
- they will respectively show the day of the week and the real time if

the parameter c8 is set at 1 (in this case the “clock” LED will be on);
the day is displayed in the 1 ... 7 format (number 1 corresponds to
Monday), the real time in the 24 hour format (hours:minutes)

• the LED will be on.
3.4
