• Digital outputs: 9
• Digital inputs: 9
• Analogical inputs: 9
• Analogical outputs: 6
Both instruments are equipped with CAN field port and a second RS485 serial interface (Modbus) allows connection to
BMS or EVCO (RICS) supervision systems.
The main control functions managed by the “Complete” solution are:
- Supply fan management
- Return fan management
- Management of the cross flow recovery heat exchanger by-pass damper
- Outside air damper management
- Management damper mixing room
- Management of hot water coil for heating (or a group of 3 electric heaters)

4. User interface
4.1 Display and keyboard
Both control solutions (compact and complete) use the Vgraph user terminal equipped with LCD graphic display
128x64 pixel and 6 keys. The terminal can be panel mounted (IP 65 with optional gasket) on the unit or remote using
EVCO wall box or in wall recess boxes type “506”. Besides the EVCO front plates it is possible to use BTicino “Living” or
“Light” series plates.
4.1.1 Vgraph interface
The interface is connected via CAN to the controller
The keyboard has 6 keys for page navigation and editing values, with the following meaning:
- UP and DOWN: in editing they modify the parameter values, otherwise they move the cursor. If the DOWN
button is pushed for about 2 seconds the buzzer is silenced.
- LEFT and RIGHT: display of the masks in succession.
- ENTER: in editing it confirms the value, otherwise it sends any control associated to the text where the cursor
is positioned. If an alarm page is being displayed pushing this key for about 2 seconds causes the alarm
reset. If the alarms pages are being displayed a short push moves to the following active alarm.
- ESC: in editing it cancel the modification, otherwise it requests for default page associated to the current
page. If the ESC key is pressed for about 2 seconds the unit is switched on/off.

6. REGULATIONS
6.1 State of the unit
There are several unit switch-on/off procedures:
1) Via the relevant ON/OFF key
Switch-ON: press the relevant key for about 2 seconds, if all the conditions are fulfilled the unit starts working
(“ON” mode).
Switch-OFF: press the relevant key for about 2 seconds, the unit stops working (“OFF” mode).
2) Using the Start/Stop from digital input control (parameter, PH05=1)
Switch-ON: close the contact, if all the conditions are fulfilled the unit starts working (“ON” mode).
Switch-OFF: if the contact is open the unit stops working (“OFF from Start/Stop” mode).
3) Via Supervision protocol (parameter, PH06=1)
Switch-ON: activate the switch-on state from protocol, if all the conditions are fulfilled the unit starts working
(“ON” mode).
Switch-OFF: if deactivated by switch-on state protocol the unit stops working (“OFF from Supervisor” mode).
The ON/OFF status from key has priority with respect to the other two. In fact the ON/OFF states by digital input and
supervision protocol can only be reached with machine in “ON” mode.
A machine switched-off by Start/Stop digital input can:
⋅ pass to the OFF state from key (by pressing ESC).
⋅ pass to the OFF state from supervisor if the OFF condition from digital input returns and the OFF state is set
by supervisor.
⋅ ass to the ON state if the ON condition from digital input returns and the OFF state is not set by supervisor.
A unit switched-OFF by supervision protocol can:
⋅ Move to the OFF state by key (by pressing ESC key).
⋅ Move to the OFF state from digital input if the OFF condition from supervisor ceases and the OFF state from
digital input is triggered.
⋅ Move to the ON state if the OFF condition from supervisor ceases and the OFF state is not present from digital
input.
The unit ON/OFF key is the ESC key pressed for about 2 seconds.
The remote Start/Stop input (when present) can be configured using the parameters:
- PH05: Enables the function
- PH52: Sets the NC, NO logic for the digital contact

6.1.1 OFF state for alarm
When the machine is active and an heavy alarm occurs the unit switches into the OFF due to alarm status. In this
case the unit and all devices are switched OFF and the dampers are completely closed until the alarm condition has
been reset. When the unit is OFF for alarm it is possible to switch to the other OFF states by means of the relevant
digital input, key or supervisor.
The alarms that cause the “OFF for alarm” are:
- Supply fan thermal overload alarm
- Return fan thermal overload alarm
- Differential pressure switch alarm
- Outdoor air Damper limit switch alarm
The unit recovers the normal working mode when the alarm has been reset.
6.2 Unit Type
While the machine is turned off, using the parameter PG00 in the MANUFACTURER Menu, it is possibile to choose the
type of unit that you wish to utilize. Based on the value of the parameters, different defualts become available for the
configuration parameters. The regulation parameters can be modified manually according to user requirements.
Note. The default configurations can also be modified according to user requirements by entering modifications to the
paramaters manually.
ATTENTION. When changing the machine type (through modification of parameter PG00) it is necessary to shutdown
and then restart the card to ensure the unit has been correctly configured; in order to allow the card to assign all the
parameters contained therein it is advisable to wait a few seconds (3 seconds should be more than sufficient) before
removing the tension.
6.3 RTC setting
When the board is disconnected from the mains for many days the RTC (Real Time Clock) system clock backup battery
discharges. At the next connection to the mains the controller will display an RTC alarm. To get rid of it and allow a
proper working condition the RTC has to be updated using the below mask:
Once the clock is configured, press OK to update the RTC and access the main page of the application. Confirmation
by pressing OK also resets any clock alarm (AL16) as long as the alarm conditions are reset.
If the alarm should not disappear switch OFF and back ON power supply to the board and manually reset the alarm.

6.4 Restore the (factory) default parameters
Via the “Parameters Reset” procedure it is possible to bring back the system parameters to the default value. The
procedure can only be activated with machine in OFF mode
Enter the Installer ->Various Parameters -> Default menu and press the ENTER key.
Set the PH99 parameter to “YES”(1) and wait until it becomes “NO”(0) again on the display. The system automatically
restores all parameters’ default values.
Note: After this operation switch OFF and back ON power supply to the board to prevent for
malfunctioning.
6.5 Last maintenance operation date
From the Installer->Maintenance menu, press RIGHT until reaching the following mask:
Positioning the cursor on the “Update” writing and pushing the Enter key the old date relevant for the previous
maintenance will be overwritten with the present date updating the PM90 parameter.

6.7
This control solution offers the base functionality present also in the "complete" solution.
Functionality of the COMPACT control solution
6.7.1 Supply and return fans
The program manages two fans, supply and return. For the two fans is expected to ON / OFF control with three steps
or analog output. . The working is the same for both fan except for the case of Recovery heat exchanger antifreeze
protection and in function with two pressure probes.
The adjustment is based on the parameter distinct PF01, which distinguishes a manual adjustment with automatic and
automatic sensor signal is likely:
• PF01=0 manual regulation
• PF01=1 automatic regulation without presence sensor
• PF01=2 automatic regulation with presence sensor
• PF01=3 automatic regulation with CO2 sensor
La regolazione può controllare direttamente la velocità dei ventilatori (PF00=0), oppure controllare la portata dei
ventilatori (PF01=1).
If the speed is controlled all the configuration parameters will modify directly the speed of the fans
(PF02/PF03/PF04/PF05/PF12/PF13) with a choice V1/V2/V3. Instead in the case of flow control these parameters will
be to choose the setpoint adjustment V1/V2/V3 pressostativa (PF33/PF34/PF35).
In ON/OFF regulation (parameter PG10=0) the 3 speeds (V1, V2, V3) are activated each by a dedicated relay.
In regulation with speed variator inverter (parameter PG10=1) the three speeds are determined by the value defined
by the parameters PF21, PF22 and PF23, or it can run in the complete control of the ramp (see the sections on
Regulations).
6.7.1.1 Manual regulation
The fans work at the MANUAL Speed/capacity set via the PF02 parameter.
6.7.1.2 Automatic regulation without presence sensor
Two time periods are defined: ECONOMY time band and COMFORT time band. A working speed is defined for each
time period, respectively ECONOMY Speed/capacity (parameter PF04) and COMFORT Speed/capacity (parameter
PF03). The fans are controlled at the Speed/capacity defined in the relevant time periods. The following parameters
must be used
• PT01: start of COMFORT time band.
• PF03: fans Speed/capacity in COMFORT band.
• PT02: start of ECONOMY time band.
• PF04: fans Speed/capacity in ECONOMY band.
For each day of the week it is possible to define whether this day is a working or non-working day, parameters
PT11=Sunday, PT12, PT13, PT14, PT15, PT16, PT17):
- Working days: the regulation is the normal automatic type for ECONOMY e COMFORT time period;
- Non-working days: the Speed/capacity are determined by parameter PF13, due to defect V0.
Note: If the RTC system clock is in alarm condition it is possible to set the PF05 parameter to determine at which
speed both fans must function.

EVCO
6.7.1.3 Automatic regulation with presence sensor
In addition to the previous regulation rules it is possible to modify the working Speed/capacity on the basis of a
presence sensor. If the presence sensor is active (indicating there is someone inside the room), during the COMFORT
time band the fans Speed/capacity is forced to the value set on parameter PF12.
6.7.1.4 Fans thermal overload
Via the digital inputs DI3/DI4 Supply/Return fans thermal overload protection it is possible to enable the thermal
overload alarm of each fan. The alarms are signalled after a fixed delay of 2 seconds and have automatic reset. The
alarms are enabled setting PA03=1. If this is not the case, the thermal overload alarms of the two fans are disabled.
The activation of the thermal overload alarm switches OFF the unit bringing it to the OFF due to alarm status.
6.7.1.5 Fans status
Each of the two fans can be in the following working states:
1. OFF: the fan is OFF.
2. ON V1: the fan is ON at speed 1.
3. ON V2: the fan is ON at speed 2.
4. ON V3: the fan is ON at speed 3.
5. Switch-ON stand-by: the fan is to be switched-on. Timing is in progress, e.g. stand-by due to pre-start of the
outside air damper. The status shows the switch-on stand-by for each of the individual speeds.
6. Switch-OFF stand-by: the fan is to be switched-off. Timing is in progress, e.g. in the case of post-ventilation.
7. Alarm: the fan is in alarm conditions due to thermal overload.
Reaching of the individual speed in switch-ON can be delayed via the parameter PF06. If PF06=0 switch-ON/OFF is
immediate.
6.7.1.6 Fans running hours
Each fan has an associated variable that counts the number of running hours (Supply fan parameter PM02, Return fan
parameter PM03). The running hours can be zeroed by resetting the relevant parameter.
If the running hours set in the PM01 parameter are exceeded, an alarm is given indicating fan running hours exceeded
(alarms AL09, AL10).
6.7.2 Recovery heat exchanger anti-freeze protection
A probe measures the temperature T of the exhaust air after the recovery heat exchanger on the extraction circuit.
The critical defrosting temperature Tg (can be set by parameter PF07) is fixed by default at 0 °C. Considering the risk
of frost in the recovery heat exchanger when T ≤ Tg it is necessary to take some action for protecting the exchanger
when this temperature level is reached. To use this function the PG06 parameter must be enabled (by default it is
always enabled).
There are two possible strategies depending on the presence of the by-pass damper of the recuperator (PG01
parameter).
Note: If the anti-freeze temperature probe is in error conditions, this regulation is not enabled and the fans are
regulated exclusively on the basis of the PF01 parameter.

6.7.2.1 Unit without By-pass damper
In this case the action taken for anti-freeze purpose is decreasing the fan speeds with a neutral zone control.
When T ≤ Tg, the outlet fan speed will decrease progressively (V3-V2-V1) until stopping (V0). If this condition occurs
and remains for a time ∆t (time set by parameter PF09) the speed reduction takes place, every ∆t there is a further
decrease until the supply fan switches OFF.
If the temperature T is between Tg and Tg + Tdiff (default 3°C, can be modified by parameter PF08) the current speed
is maintained. Only when the temperature T becomes T ≥ Tg + Tdiff the fan speed returns to the normal condition
(i.e. at the speed set by the user).

6.7.2.2 Unit with motorised By-pass
Same behaviour as in the previous case with speed reduction but never down to zero in order to allow the air flow
through the recovery heat exchanger before being eject. As the exhaust air is warmer than the outside air the heat
exchanger is “defrosted”.
When the supply fan is at minimum speed and the low temperature situation still remains for ∆t minutes, the fan does
not switch off but there’s a particular activation strategy of the recovery heat exchanger By-Pass damper:
• When T ≤ Tg - TdiffByPass (default 2°C, can be modified by PF10 parameter): opening of the By-pass damper
• When T ≥ Tg + TdiffByPass: closure of the By-pass damper.

The return to normal working condition (speed selected by the user and By-Pass closed) takes place only when T ≥ Tg
+ Tdiff (default 2°C, can be modified by PF08 parameter).
The by-pass damper can be controlled using a digital signal or an analogue signal, it must be configured setting the
PG03 parameter from the manufacturer menu.
PG03=0
The damper is managed with a digital control via the DO7 relay. When the relay is not active the damper is closed
while when the relay is active the damper is open and the recovery heat exchanger is by-passed.

6.7.3 Cross flow recovery heat exchanger and by-pass
damper
The recovery heat exchanger to be used is the cross flow static type. The anti-freeze by-pass damper can be present
in the unit (optional PG01 parameter).
This damper allows the unit to work with very low outside air temperatures (e.g. –10 / -12°C) preventing the moisture
of the ejected air to condensate and freeze inside the heat exchanger (which would cause the obstruction of air flow up
to complete block).
The anti-freeze temperature probe identifies the freezing temperature and drives the fan speed decrease and the
activation of the recovery heat exchanger by-pass damper.
The recovery heat exchanger is normally active and is by-passed (opening the by-pass damper) only during free-
cooling (if present and enabled) and during cyclical defrosting when outside temperature is too low. To activate this
function set PG06 = 2
6.7.3.1 Cyclical defrosting with minimum temperatures
The set point must be determined along with its differential for the activation of the defrosting cycle.
When the anti-freeze minimum temperature condition is reached a cyclical by-pass sequence of the recovery heat
exchanger is activated to allow the exhaust air (warmer, from the room) to defrost the recovery heat exchanger air
channels as shown in the below diagram.

After the (parameter Pr03) delay the by-pass damper is activated to allow defrosting. As soon as the exhaust air
temperature is back above the accepted value the damper is deactivated and the recovery heat exchanger starts
again.
Note: If the anti-freeze probe is in alarm condition the function is disabled.
6.8 Features of the COMPLETE control solution
Al functions of the COMPACT version are included in this version.
Below are listed only the additional features of the COMPLETE control solution.
6.8.1 Post-Ventilation
By setting the parameter PG05=1 it is possible to decide whether to run the fans for a time configured on parameter
PF11, also after unit switch-OFF. If the function is active when the unit stops the fans keep working for further PF11
seconds.
6.8.2 Differential pressure switch
The lack of air flow is signalled via the DI5 Differential Pressure switch digital input. The pressure switch status is
considered after the initial start-up phase of the unit (the length of this phase is configured by parameter PA06). On
expiry of this time if the contact signals a lack of air flow the alarm is signalled immediately. During normal working
the differential pressure switch is monitored continuously. If the contact signals a lack of flow for a period exceeding
the PA06 parameter, the alarm is signalled immediately.
To enable the alarm, set PA05=1.
The differential pressure switch alarm has manual reset. Activation leads to switch-off of the unit taking it into the OFF
due to alarm status.

6.8.3 Fresh air intake damper
It is possible to manage an optional motorised damper (can be enabled by parameter PG04=1) for fresh air intake
purpose. The damper is managed via ON/OFF (digital) activation. The damper can be either fully open or fully closed,
modulation is not possible as well as a minimum opening.
When the fans are requested to start first the damper is opened and, after a delay configured on parameter PS01, the
fans are activated too.
When the fans are switched OFF the damper is kept open for a time configured on parameter PS02.
6.8.3.1 Fresh air intake damper limit switches
In order to have a feedback about the real status of the damper (fully open or fully closed) the digital inputs DI9 and
DI10 are connected to the damper’s “fully open” and “fully closed” limit switches. Every time the damper is requested
to change its status it is verified that both limit switches change their status within the expected time frame (defined
on parameter PS05). If during this time the states of both digital inputs change this means everything is working fine.
If this is not the case the AL06 alarm with manual reset is generated and the unit is brought to the “OFF due to alarm”
status.
6.8.4 Damper mixing room
La serranda viene regolata in base al parametro PS074, e può essere utilizzata per:
- Free-Heating
- Air quality control
- The larger of the 2 requests
- The average of the 3 required
- A fixed value
The adjustment also provides a minimum opening position of the damper to ensure the design minimum quantity
of fresh air (parameter PS08) and the corresponding position of maximum opening (parameter PS09).
If the setting is fixed aperture in the louvre is always the same aperture value decided by the parameter PS10.
If the adjustment is freeHeating, is activated when the temperature difference between the outside air and the
return air temperature reaches the setpoint (parameter PS13) and the response threshold (parameter PS12).
When there are conditions of free-heating, or is there a license to regulation (and the demand is greater than zero)
that controls the ramp heating is split into two flights later, the first one (about half the switching differential) adjusts
the free-heating by means of the damper, the second rule the users in charge of the heating.

Note: If the air quality sensor is in error adjustment is inhibited.
6.8.5 Heating
The COMPLETE solution offers the possibility to use a hot water coil or a set of three electric heaters for space heating
purpose. By setting the PG02 parameter the desired resource is activated along with the relevant alarms connected.
For using this function it is necessary to enable the supply temperature probe setting PH40=1.
During the anti-freeze protection of the recovery heat exchanger, on units without by-pass, the heating source must
be deactivated for protection. The heating source is disabled with a delay defined at the parameter PF09 after the fan
speed has reduced to V1 during the supply fan speed decrease for antifreeze protection. If the antifreeze condition
remains active for further PF09 the supply fan is stopped.
6.8.5.1 Heating with hot water coil
To use the hot water coil for space heating it is required to set the parameter PG02=1. The control is based on the
supply temperature via a supply Set Point (SPHM parameter) and a relevant differential (Pb02 parameter). The coil is
controlled via a proportional-integral algorithm (PI). The control can be only proportional by setting the integral time
Pb03=0.

In case the control probe has an alarm condition it is possible to decide the opening percentage of the coil valve during
alarm setting the Pb04 parameter. If Pb04 = 0.0% in probe error condition the valve remains closed.
Anti-freeze safety on hot water circuit (AL04)
The anti-freeze mechanical thermostat (digital input DI6) is mounted downstream the coil either inside or outside the
pipe. On its intervention (voltage free contact closure on controller digital input), the controller carries out the
following steps:
a) Open the 3-way valve completely (hot water)
b) Close the fresh air damper
c) Stop the fans
This alarm is enabled by setting PA08=1 and is only active if the hot water coil is enabled (PG02=1). The alarm is
signalled after a set delay (parameter PA09) and is reset automatically.
6.8.5.2 Heating with electric heaters analog
To use the electric heaters for space heating purpose it is necessary to set the parameter PG02=3.
The adjustment is the same as the water battery, is controlled by an algorithm proportional-integral (PI), the
adjustment can be only proportional setting the integral time Pb03 = 0.
6.8.5.3 Heating with electric heaters (3 stages)
To use the electric heaters for space heating purpose it is necessary to set the parameter PG02=2. The control is
based on the supply temperature via a supply Set Point (SPHM parameter) and a relevant differential (Pb02
parameter.
Between following activation / de activation of the heaters a delay has been implemented (parameter Pb05) in order to
prevent for simultaneous current peaks.

EVCO S.p.A. c-pro 3 micro SAVE/ c-pro 3 kilo SAVE | Application Manual ver. 1.0 | Code 144CP3UKSAE104
EVCO
In case the control probe has an alarm condition it is possible to decide the number of heaters to be activated during
the the alarm by setting the Pb06 parameter. If Pb06=0 in probe error condition no heater is active.
Heaters thermal overload alarm
Via the DI6 (Electric heaters thermal overload protection) digital input it is possible to activate the heaters thermal
overload alarm. On occurrence of this alarm the heaters are immediately switched OFF. The alarm is signalled after a
fixed delay of 2 seconds and is reset automatically. The alarm is enabled by setting PA12=1. The alarm can be enabled
only if the heaters are configured (PG02=2, PG02=3).
6.8.5.4 Heaters status
Each of the three heaters can assume one out the following status:
1. Disabled: the heater is not managed by control.
2. Off: the heater is not active.
3. In switch-ON stand-by: the heater is about to switch-ON, it is in stand-by due to protection times.
4. In switch-OFF stand-by: the heater is about to switch-off, it is in stand-by due to protection times.
5. On: the heater is active.
6. Alarm: the heater is blocked due to the relevant thermal overload alarm.
7.
6.8.5.5 Heaters over temperature protection with
automatic reset
By setting the parameter PA16=1(high temperature) it is possible to decide whether to use the supply high
temperature alarms or not. The following parameters must be configured in order to use these alarms:
- PA17 = Automatic reset over temperature protection Set Point
- PA19 = Temperature alarm differential
- PA20 = Temperature alarm activation delay
The alarms are signalled after the PA20 delay time have automatic reset. The alarms are disabled in case of alarm
condition on the supply temperature probe. These alarms can only be activated with the unit running.
6.8.6 Heat exchanger by-pass in summer mode (Free-
Cooling)
During summer cycle, when the outside temperature is low enough it is possible to take advantage of the outside air
for cooling down the internal ambient by means of the by-pass damper. Set PG08=1 to enable this function. This
function uses the outside air temperature probe (TExt) and the return temperature probe (TInt).
When TExt ≥ Tke (default 15 °C, it can be modified by parameter Pr04) and return temperature TInt ≥ Tki (default 22
°C, it can be modified by parameter Pr05) and if TExt ≤ TInt the function is active and opens the heat exchanger by-
pass damper.
Note: To use this function the outside and return temperature probes must be enabled, respectively PH43=1 and
PH41=1. If one of the two probes is in error condition the function is disabled.

6.8.7 Modulation of the air flow with CO
This function is enabled only at the times COMFORT. It provides for the modulation of fan speed according to the value
read by the probe of CO2 and is activated by setting PF01 = 3. The speed modulation takes place according to a PI
control (if PF17 = 0 only proportional control).
PF16 = 1 with parameter adjustment is a ramp like the following:
probe

PF14:Set
In case of parameter PF16 = 0 the adjustment is in steps, the steps are calculated according to the previous ramp broken within the
values indicated by the parameters PF21 (value variable speed corresponding to the speed V1), PF22 (value variable speed
corresponding to the speed V2 ), PF23 (value variable speed corresponding to the speed V3)
Note: To use this feature, you must enable the CO2 probe (parameter PH42 = 1) and the relative values of linearization (parameters
PH03 and PH04).
6.8.8 Adjusting the static pressure
This feature provides for the modulation of the fan speed as a function of the pressure of canale.e is activated by setting PF00 = 1. The
speed modulation takes place according to a PI control (if PF37 = 0 only proportional control).

The static pressure setpoint supply air is moved up slowly from 0 to the setpoint target when you start the central
unit. The ramp time is defined by parameter PF32, setpoint adjustment ramp static pressure.

PF31: maximum fan speed
PF32: Adjust the static pressure setpoint ramp

If PH44 = 1 Fan speed is equal to the supply and return fans.
If PH44 = 2 The fan speed is independent for supply and extract (pressure1 for channel flow and pressure for 2
channel recovery.)
6.8.9 Heating control depending on Return Air Temperature
It is possible to decide whether to control the space heating (by means of hot water coil or electric heaters) depending
on the return ait temperature instead of on the supply air temperature (Pb01=0). To use this function set Pb01=1 and
also set the SPHR parameter indicating the value of the regulation set point on the return air temperature. To use of
this the return air temperature probe must be enabled (PH41=1).
6.8.10 Alarm fire/smoke
This function is activated by parameter PA51. This parameter is used to determine the speed of the fans (return and
supply).
Here are the values:
• PA51 = 0: Disabled
• PA51 = 1: Stop (Fire Unit OFF)
• PA51 = 2: Stop V3 + supply fan - Fan recovery V3
• PA51 = 3: Stop + V0 supply fan - Fan recovery V3
The alarm is reset automatically and immediately reported.
7. DIAGNOSTICS
The application can manage a series of alarms relevant to the fans and the devices configured. Depending on the
various types of alarm it is possible to configure a manual or automatic reset, a possible delay and the actions to carry
out in the specific case.
When one or more alarms are active the alarm icon on the main page flashes, if configured (PH20=1) and only
with the machine ON the buzzer is also activated.
To display the alarms, select ALARMS on the general menu or press ESC from the main page and then select “Show
ALARMS >>”.
If the ESC key is pressed on an alarm page or you wait 60 seconds for timeout, go back to the main page of the
application. To scroll through the various active alarms, press ENTER again: the alarms are presented in the order of
priority, as they are listed in the alarms table.
To silence the buzzer, press the

7.1 Manual and automatic reset alarms
As shown previously there are two types of alarm. Those with manual reset and those with automatic reset. For some
alarms it is possible to set (Alarms Reset) the most suitable type of reset for user needs by means of the relevant
parameters. Other alarms have predetermined reset type.
7.1.1 Manual reset alarms
If a manual rest alarm occurs the alarm icon starts to flash and the buzzer is activated (if configured PH20=1).
Once the conditions for which the alarm has occurred are reset it is possible to manual reset the alarm. To perform
this operation:
⋅ Enter the relevant alarm page
⋅ hold the ENTER key down for about 2 seconds.
At this point, if there are no other active alarms, the page indicating “NO ALARMS” will be displayed, the icon
disappears, the buzzer switches off and the unit starts working normally. If there are other active alarms the page
relevant to the next active alarm will be displayed.
The consequences relevant to an active manual reset alarm remain valid until the user reset the alarm message.
7.1.2 Automatic reset alarms
If an automatic reset alarm occurs the alarm icon starts to flash and the buzzer is activated (if configured PH20=1).
Once the conditions for which the alarm occurred are reset the alarm message and the relevant consequences are
reset automatically without need of user intervention.

7.3 General alarm relay
The controller manages a configurable alarm relay. For each alarm there is a parameter which selects whether that
alarm must be signalled on the alarm relay. Several alarms can be addressed to the relay.
Via the relevant parameter (PH61) it is possible to establish the polarity (NO, or NC) of the alarm relay.
7.4 Alarms log

- Alarm occurrence date and time
- A possible value associated to the alarm
The alarm mnemonic code is the one shown in the alarms table. The log can hold 100 events.
Via the PH18 (Delete alarms log) parameter it is possible to cancel all the alarms stored in the log. Set the parameter
at SI (1) and wait a few seconds for the NO (0) default value to be read again.
