CHAPTER 1: INTRODUCTION
1.1
GENERAL
The PLUS 100 PAN system allows the user to control temperature and humidity. The
system consists of the 100 MASTER unit, on which all the electrical connections are
made, and the PLUS 100 PAN control panel, which features a large LCD display to
provide rapidly available, complete information on room status. The system allows the user
to cool, heat and ventilate the room, switch the room light on/off, humidify it, effect an air
changeover, dehumidify it, defrost it and control alarms.

CHAPTER 2: INSTALLATION
2.1
IMPORTANT INFORMATION FOR THE INSTALLER
1. Install the device in places where the protection rating is observed and try not to
damage the box when drilling holes for wire/pipe seats.
2. Do not use multi-polar cables in which there are wires connected to inductive/power
loads or signalling wires (e.g. probes/sensors and digital inputs).
3. Do not fit power supply wiring and signal wiring (probes/sensors and digital inputs) in
the same raceways or ducts.
4. Minimise the length of connector wires so that wiring does not twist into a spiral shape
as this could have negative effects on the electronics.
5. Fit a general protection fuse upstream from the electronic controller.
6. All wiring must be of a cross-section suitable for relevant power levels.
7. When it is necessary to make a probe/sensor extension, the wires must be of the
correct cross-section, which in any case must be at least 1 mm2.

CHAP. 6 - Using the unit
CHAPTER 6: USING THE UNIT
6.1
COLD/HEAT: MAINTAINING AMBIENT TEMPERATURE
Heating/cooling is neutral-zone controlled on the basis of the temperature set-point (key 6
) and the temperature differential (parameter d-t).
Cooling is activated when the set + differential threshold is passed and stays on until the
set-point is reached.
Heating is activated when the setting – differential threshold is reached and stays on until
the set-point is reached.
6.2
HUMIDIFICATION/DEHUMID.: MAINTAINING AMBIENT HUMIDITY
Humidity and dehumidification are neutral-zone controlled during the leavening,
maintenance and settling phases only, and only if the programmed set-point is greater
than the settable minimum *(50%) on the basis of the humidity set-point (key 6
) and
the differential for Humidification (parameter d-U) and differential for Dehumidification
(parameter d-d).
Humidification is activated below the set – differential for Humidification (parameter dU) threshold and stays on until the set-point is reached.
Dehumidification is activated above the set + differential for Dehumidification
(parameter d-d) threshold and stays on until the set-point is reached.
Humidity control can be disabled via the Hr (relative humidity) parameter, or by setting the
set point to the minimum R.H.% 50 = humidity control disabled (display only).
Dehumidification alone be disabled via the End parameter.
Humidification alone can be disabled via the EnU parameter.
There are three dehumidification modes (dEU parameter ):
1. Dehumidification with cooling (cold is called to dehumidify, heat is added only to
maintain ambient temperature).
2. Dehumidification with heating (heat is called to dehumidify, cold is added only to
maintain ambient temperature).
If the difference in temperature is, with respect to the setting, greater than 5°C
(during dehumidification with the compressor and elements) 5°C, the unit with the

greater value shuts down to prevent any overheating or over-cooling which could
damage the product.
3. Separated dehumidification (dehumidification output activated only but without
cold/heat call).
(*) if the humidity set point is set to the minimum (50%) neither dehumidification nor
humidification are controlled
VENTILATION
6.3
Fan speed is regulated by two digital outputs (high/low speed) and run at high speed with
the cold call during the cooling and maintenance phases and continuously at low speed
during the leavening and settling phases.
Fans are always off during defrosting.
Variants can be controlled via parameters F5 and F6.
AIR CHANGEOVER
6.4
Air changeover is controlled via parameters d0 and d1.
Use d0 to establish the interval between one air changeover and another: the counter
starts its count from zero at the start of every manual or automatic leavening cycle. If d0 =
00 no air changeover is carried out.
Use d1 to establish the duration of the air changeover.
Cooling, heating, humidification and dehumidification are not activated during air
changeover.
CLOCK / CALENDAR
6.5
Current time and date can be adjusted via the dMY and HMS parameters.
The current time is shown on the LCD display.

USE AND MAINTENANCE MANUAL

MANUAL CYCLES
6.6
The controller recognises the manual cycles (only hot or only cold) from the temperature
setting only when in stop mode, not in stand-by.
If the set-point is less than or equal to 10°C the controller recognises the manual cold
cycle. It will consequently run the fans simultaneously with the compressor call and
execute the programmed defrosts as per the parameter settings; humidity control will not
be executed.
If the set-point is higher than 10°C the controller recognises the manual hot cycle.
Consequently the fans are run continuously, humidity is controlled according to the RH%
setting and the defrost cycles are not executed.

AUTOMATIC CYCLES
6.7
It is possible to set four automatic pause-leavening cycles each with fully independent
automatic programmed leavening, and a maintenance-only cycle (riC 0) with cooling start.
The four cycles have the following characteristics: cycle n°1 is carried out the same day
(12 hrs); cycle n°2 is for the next day (24 hrs); cycle 3 for the second successive day (48
hrs); and cycle 4 for the third successive day after the (72 hrs).
To enter the recipes programming mode press key 4
until the letters riC appear on
the temperature display and the numbers 01 … 04 on the RH% display. Use keys 4
and 7
to select the recipe to be programmed, press key 3
to enter
programming mode for the selected recipe. The 20 segments at the top of the unit should
all be off: only one of the first four will remain on to remind you of the recipe you are
programming. To program the data proceed as follows:
1. Use the (t) or (u) key to select the variable to be modified. After selecting the desired
variable it will be possible to:
2. View the value on the respective sector of the display (5 or 17 page 11).
3. Modify the setting by pressing or maintaining the SET key
and pressing the (t)
or (u) key.
Exit programming mode [from the product ready day window (LI6)] by keeping key 4
pressed for 2 seconds; in any case the unit will exit programming mode if no keys are
touched for 30 seconds.

for this recipe are therefore AC1; AC2; Co1; Co2.
Once programming has been completed you can start a cycle by pressing key 3
for a few seconds. The display asks which recipe is to be used (riC 00 … riC 04).
Select the desired recipe via the up/down keys: when key 3
is pressed again the
product ready (oven-ready) time and day are displayed for 5 seconds. If the shown data is
correct there is no need to carry out any further tasks and the controller makes subsequent
checks and then starts the cycle. If, however, the data is incorrect stop the cycle by
pressing key 3
, enter the recipe, modify the incorrect data and restart the cycle.
The controller makes a quick calculation to see if the cycle duration time is
compatible with the “product ready” time and day. If everything is compatible the cycle
begins and the first segment lights up. If, instead, there are incompatibilities the controller
goes to stand-by, the buzzer sounds and the EP message appears on the display to

Phase 1: cooling n° 5 segments;
Phase 2 maintenance n° 5 segments;
Phase 3 leavening n° 6 segments;
Phase 4 settling (where enabled) n° 4 segments.
If a settling phase is enabled sector 19 will light up at the cycle START to remind the user
that, when the product ready time is reached, the cycle will be completed by a settling
phase. It goes off at the start of the settling phase (i.e. when segment n° 17 lights up).

be viewed on the RH% display and the baking day/time displayed alternately on the clock
display (17) for a few seconds by pressing key 3
briefly. While a complete cycle is in
progress you can view and modify the recipe in use by pressing key 4
for 2
seconds: you can vary temperature and humidity but not the duration times of the
different stages.
At the end of the final leavening cycle (if settling is not enabled) the controller goes
to stand by. The buzzer sounds and the segment bar flashes to indicate that the cycle is
over. Buzzing/flashing stops automatically after 1 minute or when key 7
is pressed.
The user can vary temperature and humidity set-points alternately at any time
during the active cycle (manual heat/cool cycles included) via key 6
: note, however,
that during a complete cycle variation of the set-point is relative to the phase in progress.
The first phase is known as cooling (cold is produced and “accumulated”). If the recipe has
a cooling time of 0:00 the controller immediately goes to the maintenance phase at the
start if the cycle.
There then follow: maintenance, intermediate leavening, final leavening and (where
enabled) settling.
N.B. the end of the cycle (Li4 - product ready time) is defined by the end of the final
leavening phase, not the settling cycle.

The cooling phase is characterised by:
•
Temperature set-point
•
Duration of the phase
The maintenance phase is characterised by:
•
Temperature set-point
•
Humidity set-point
The leavening phase is characterised by:
•
Temperature set-point
•
Humidity set-point
•
Duration of the intermediate leavening phases via 2nd level parameters and overall
leavening duration programmed by final user. N.B. overall leavening duration can
never be less than the sum of the 5 parameter-programmed steps.
The settling phase is characterised by:
•
Duration in hours (2nd level parameter)
•
Temperature set-point (2nd level parameter)
•
Humidity set-point (2nd level parameter)
If a phase has time 0, it is not executed and the controller goes to the next phase.
Phase times continue even in the event of an electrical power failure or controller stand-by.
When an automatic cycle is in progress it is possible to check the number of the cycle in
use and the in-oven day / time by briefly pressing key 3
(CYCLE START); sector 17
of the display (DATE TIME) shows first day and then time.

Supervision/monitoring system TeleNET
6.8
The TeleNET supervision system allows the user to create a historical room temperature
and humidity database via Personal Computer.
To configure the instrument, refer to the TeleNET manual.
Assign the PLUS 100 PAN system address via the configuration sequence by selecting
the Ad label from the 2nd programming level (installer level) and following the normal
address attribution criteria used for TeleNET.
Temperature as detected by the controller can be displayed at the TeleNET address Ad+1
by setting the module as TWMT (temperature acquisition module).
In this way the TeleNET supervision program can simultaneously display temperature and
relative humidity as measured by the PLUS 100 PAN and build up a record of both
parameters.
Example: if parameter Ad is set to 3, relative humidity can be displayed on the TeleNET
by assigning the TWMUR module to address 3; temperature can be displayed by
assigning address 4 (obtained by summing one to the parameter Ad=3) as the TWMT
module.
N.B. The address Ad+1 can, in any case, be used by any device connectable to the
TeleNET (in place of PLUS 100 PAN temperature display) except for TWMT modules to
which a different address must be assigned so as to avoid any conflict.
