1 GENERALITIES

1.1 Description

The c-pro CLIMA Climatic Modules allow to realise innovative control and regulation networks in
distributed logic, for air-conditioning and heating systems in residential and commercial buildings,
characterised by the most demanding and modern necessity for environmental comfort, system
performance and energy savings.

The Climatic Modules are programmable controllers dedicated specifically to the regulation of the
different parts of the systems:

• c-pro Mega MCCT, for THERMAL POWER PLANT, where there is a boiler, chiller
and/or heat pump present with relative delivery pumps and safety devices.

• c-pro Micro MCZN, for the various ZONES, where it is necessary to control the regulation
of the temperature and humidity in the room, via heated or cooled floors and dehumidifiers.

• c-pro Micro MCDE, can manage the most different types of DEHUMIDIFIERS for every
zone, which also have integration and support systems for heating and/or cooling the room.

• c-pro Micro MCPS, dedicated to the management of the glycoled circuit of the SOLAR
HEAT PANELS and for the circuit of the heating and/or domestic hot water with DHW
tank.

Other specific components of the CLIMA system are dedicated for the completion of the
requirements of every conditioning and heating system:

• Vgraph, ZONE TERMINALS for the user, which allow to display and set the temperature
and room humidity values, the alarms and the time band of each zone.

• EVSET, ZONE SET VARIATOR not displayed, with temperature probe on board, able to
modify the room temperature in order to reach maximum well-being.

• Flow switches, air quality probes (and CO2), temperature and immersion humidity probes,
channel or room.

Some features of the Climatic Modules and the components of the c-pro CLIMA system must be
highlighted:

• Flexibility: allows to design and realise the correct and convenient regulation and control
solution for every type of building, thanks to the capacity of the modules to adapt to the
needs of every type of system.

• Modularity: allows to insert the number and type of modules and components necessary to
satisfy the requirements of every user and every different and specific new system to be
realised, obtaining complete stability of the application software, which must not be realised
or modified for very new system that a plant engineer must build (possibility of modifying
or developing software, which being programmable controllers remains in all cases).

• capacity of communication among modules and some components, via the CANbus field,
which makes the realisation of distributed control network possible in the building, instead
of the traditional centralised system. This has the important and fundamental result of
reducing realisation times and costs of the electric wiring of the air conditioning and heating
system.

Page 5

C-PRO CLIMA SISTEMA INSTALLER MANUAL

• Availability of MODBUS communication, from the Modules to a BMS system supervision
system via a serial output, also suitable for the configuration phases or modification of

controller parameters in the system installation or maintenance phases.
All of these features mean an innovative control and regulation system, from high performance
resulting in great system efficiency with consequent maximum energy saving.

Number of zone regulators in the system

3.4.1 MCCT thermal power plant controller network configuration

As the thermal power plant controller is the logical centre of the system controlled, it is first
necessary to set how many MCZN zone regulators will be present in the system, following the
procedure given below:

1. Enter the Installer  General parameters menu of the MCCT regulator

2. Set the total number of zones controlled and the number of MCZN zone regulators present in

the system

3. Set the c-pro mega MCCT J4 jumpers in the position corresponding to the communication

speed of 125Kbyte, as given in the figure below.

3.4.2 MCZN zone controllers network configuration

The zone regulator leaves the factory configured as zone 1 regulator (therefore with CANbus 2
address).
Whenever it is necessary to install more than one zone controller in the system, it will be necessary
to configure the regulators present as zone regulators 2, 3, etc…up to a maximum of 8.

To change the network configuration of the MCZN zone controller network, follow the procedure
below:

1. Connect a zone regulator to the CANbus network (leaving all of the other zone regulators

disconnected from the network);the controller connected will be recognised as zone 1

controller

2. Access the MCZN zone regulator application as shown in chapter 5.2.1

3. Enter the Installer  General parameters menu

4. Set the number of local zones managed by the MCZN regulator (1 or 2 local zones)

5. Set the number of the last zone regulator that is to be inserted in the system managed (e.g.

zone 4 regulator).

6. The controller will automatically assume the appropriate CANbus address (address 25 for the

regulator of zone 4)

7. Repeat the operation, connecting the next to last zone controller to the CANbus network and

so on, until the first zone regulator is connected (zone 1 regulator).

3.4.3 Network configuration of controllers for additional MCDE dehumidifiers

Once the MCZN zone regulators have been configured, if present, it is possible to associate the
relative regulators for additional MCDE dehumidifiers to the same.
The regulator for dehumidifiers leaves the factory configured as regulator associated to zone
1(therefore with CANbus 22 address).
Whenever it is necessary to install more than one controller in the system for dehumidifiers and/or
to vary the association of the controller for dehumidifiers at the zone controller it will be necessary
to configure the regulators present appropriately.

Enabling of presence of a MCDE module for additional dehumidifiers associated to the MCZN
regulator

1. Access the MCZN zone regulator to which the regulator for additional dehumidifiers is to be

associated, as shown in chapter 5.2.1

2. Enter the Installer  Dehumidifyer menu

3. To enable the control via the appropriate parameter.

The CANBUS address field will automatically show the CANbus address that
the regulator must assume for additional dehumidifiers

CANbus address that the regulator must assume for
additional dehumidifiers

To change the network configuration of the MCDE zone controller network, follow the procedure
below:

1. Connect a regulator for dehumidifiers to the CANbus network (leaving all of the other

dehumidifier regulators disconnected from the network);the controller connected will be

recognised by the system as controller for dehumidifier associated to zone 1

2. Access the application of the regulator for MCDE dehumidifiers associated to zone 1, as

shown in chapter 5.2.2

3. Enter the Installer  General parameters menu

4. Set the number of the MCZN zone regulator to which to associate the connected regulator for

additional MCDE dehumidifiers

5. Return to the MCCT thermal power plant regulator main menu

6. Repeat the operation connecting the next controlled for additional dehumidifiers to the

CANbus network and so on, until all regulators for envisioned additional dehumidifiers are

connected.

3.5 Displays network configuration

For the final user, the c-pro CLIMA system envisions the use of a series of user terminals installed
in zone, from which it is possible to display temperature, humidity, state of the zone and set the
work set-points, time bands, etc.
The maximum number of user terminals that can be set in the system depends mainly on the
configuration of the terminal selected by the installer, from the following possibilities:

• Public terminal (maximum n°1 display for the entire system)

• Module private terminal (maximum n°8 displays for the entire system)

• Zone private terminal (maximum n°8 displays for the entire system)

Depending on the type of terminal desired, settings must be made in the MCZN zone controller and
in the Vgraph user terminal, illustrated in the following paragraphs.

3.5.1 Public terminal

If the Vgraph display is configured as a public terminal (universal), a unique Vgraph display can
show all MCZN zone controllers present in the system and all zones managed by the MCZN
controllers (called Zone A, Zone B).

A hotel is given as an example.
The unique Vgraph display will be installed in an area with access to authorised staff only, which
will establish the temperatures and time bands predefined for every Zone (hotel room) managed.
The hotel client will only have the possibility to change the room temperature, using the EVSET
remote set-point variator (installed in the room), by ±3-5°C (from parameter).

If the Vgraph display is configured as a private module terminal (AB), every Vgraph display will be
able to only show the preselected MCZN zone regulator, managing both zones (called Zone A,
Zone B) managed by the MCZN controller.

A condominium is given as an example.
A Vgraph display will be installed in every apartment, which will establish temperatures and time
bands for the two Zones present in the apartment, (day zone/night zone or apartment/bathroom),

4 USER INTERFACE

4.1 Display and keyboard

A unique incorporated interface is envisioned for the application (herein called built-in) in the
MCCT controller with 4 x 20 characters alphanumerical display and several dedicated keys and
LEDs.
The built-in display of the MCCT controller is the only user interface available for the installer and
the maintenance technician of the c-pro CLIMA system. All settings and configurations of the
modules connected will be performed via a unique display.

4.1.1 Built-in interface

The built-in interface is integrated directly onto the MCCT.

There are 9 navigation and value editing pages present in the keyboard with the following meaning:

- and (UP and DOWN): when editing it modifies the parameters; otherwise moves the
cursor.

- (LEFT): moves the cursor to the left or takes to the previous menu.

- (RIGHT): moves the cursor to the right.

- (ENTER): in editing it confirms the value; otherwise it sends any controls associated to the
text where the cursor is present.

- (ESC): in editing it annuls the value; otherwise request of the default page eventually
associated to the current page. If the ESC key is held for about 2 seconds, the machine can be
switched on/off,

- (K0): used to silence the alarm buzzer.

- and : they are keys not used.

5.10 State of the unit

There are several procedures for switching the unit on/off:

1) Via the relative On/Off key

Switch-on: press the relative key for about 2 seconds: if all of the other conditions enabled

are present, the machine goes to "ON".

Switch-off: press the relative key for about 2 seconds: the machine goes to "OFF" mode.

2) Via the On/Off from digital input control (ONOFF d.input = 1 parameter)

Switch-on: close the remote On/Off contact: if all of the other conditions enabled are

present, the machine goes to "ON".

Switch-off: if the remote On/Off contact is open, the machine goes to “OFF from digital

input” (also signalled by “OFF digital in.”).

3) Via supervision protocol

Switch-on: to activate the switch-on state from protocol: if all of the other conditions

enabled are present, the machine goes to "ON".

Switch-off: if the ignition state is deactivated from protocol, the machine goes to “OFF from

supervision protocol” (also indicated by “OFF supervisor”).

The On/Off state from key has priority with respect to the other two. In fact, the On/Off states from
digital input and supervision protocol can only be reached with machine on from key.

A machine switched off from digital input can:

⋅ pass to the OFF state from key (by pressing the ESC key).
⋅ pass to the OFF state from supervisor if the OFF condition from digital input returns and the

OFF state from supervisor is set.

⋅ pass to the ON state if the OFF condition from digital input returns and the OFF state from

supervisor is not set.

A machine switched off from supervision protocol can:

⋅ pass to the OFF state from key (by pressing the ESC key).
⋅ pass to the OFF state from digital input if the OFF condition from supervisor returns and the

OFF state from digital input is tripped.

⋅ pass to the ON state if the OFF condition from supervisor returns and the OFF condition

from digital input is not present.

The machine On/Off key is the ESC key, pressed for about 2 seconds.
The remote On/Off input (when present) can be configured via the parameters:

- ONOFF D input: Enables the function

- D In 6 : Sets the NC, NO logic for the digital contact

5.10.1 OFF state due to alarm

When the machine is on, a further state exists OFF due to alarm, which switches the nit and all
devices off until the alarm condition has been reset. If digital consent is missing in this state from

Page 38

supervisor or switch-off is requested from key, the power plant goes into the relative OFF state. The
alarms that cause this state are:

- Delivery 1 probe alarm

- Delivery 2 probe alarm

The machine works normally again when the alarm has been reset.

5.11 Summer/winter functioning mode

The operational mode can assume the following values:

E/I keyboard parameter Description

S= SUMMER Summer functioning mode
W= WINTER Winter functioning mode

There are procedures that allow to set the c-pro CLIMA system functioning mode:

1) Via the parameter regarding S/W keyboard in the maintenance menu

Setting - Be positioned on the S/W keyboard parameter and, pressing the ENTER key,
modify the value using the UP and DOWN keys. Confirm by pressing ENTER again.

2) Via supervision protocol (function enabled by parameter S/W BMS)

Setting - Send the operational mode change control via relative state from protocol.

This control has priority with respect to the S/W control from keyboard

3) Using the Estate/Inverno da ingresso digitale (Summer/winter from digital input) control

(function enabled from S/W D. Input parameter.

Setting - With contact open the unit is in “winter” functioning mode, with contact closed in

“summer” functioning mode.

This control has priority with respect to the S/W control from supervision protocol

4) Using summer/winter automatic switch-over function (function enabled from S/W Auto

parameter)

Setting - Switch-over from summer to winter takes place when the external temperature

remains above the value established with the T.Ext S parameter for the time established by

the W/S delay parameter

Vice versa, switch-over from winter to summer takes place when the external temperature

remains below the value established with the T.ext W parameter for the time established by

the W/S delay parameter

This control has priority with respect to the S/W control from digital input

As well as selection of the operational mode, a digital output is linked to the summer/winter
functioning mode, which functions as follows:

Functioning mode State of the digital input

S= SUMMER Summer/Winter output ACTIVE
W= WINTER Summer/Winter output OFF

A typical application of the summer/winter relay is to automatically inform the chiller/heat pump
unit of the system functioning mode.

Note. For the two manual summer/winter change modes (procedures 1 and 2) it is recommended to
carry out the summer/winter change with the machine off.

The state of the MCZN regulator is given by the state of the MCCT thermal power plant regulator.

6.9 State of Zone A and Zone B

There are two ways to vary the state of Zones A and B:

1) Using the On/Off keyboard control

Using the On/Off pages described in chapter 7.5

2) Using the Zone A and Zone B On/Off controls from digital input

Switch-on: close the remote Zone A/B On/Off contact: if all of the other conditions enabled
are present, the regulation of Zones A/B goes to "ON".
Switch-off: if the Zone A/B remote On/Off contact is open, the regulation of

9 Regulations

This chapter will state all main regulations made by the c-pro CLIMA system.
At the side of the title of every paragraph, in brackets find the control module or modules involved
in these regulations.
It can therefore be immediately understood from which application to set the function and if the
function is available or not in the system available, depending on the presence or not of the control
modules indicated.

9.1 Regulation of the zone temperature

9.1.1 Regulation principle

Depending on the system functioning mode (summer or winter) and the time band active in every
zone regulated by the system (manual, economy, comfort in summer and manual, anti-freeze,
economy, comfort in winter), when the temperature detected by the room probe is over (summer) or
below (winter) the active zone set-point value plus the value of the differential for that zone, the
MCZN regulator will activate the corresponding zone heating/cooling manifold.

The activation of the manifold automatically generates an activation request for the delivery
circulation pump in the MCCT controller (delivery line 1 or delivery line 2) that serves the
requesting zone which, after a delay time that can be set from the parameter, activates the
circulation of water in the system and the management of the mixing valve.

After activation of the circulation pump the delivery water temperature control is performed.
Whenever the temperature of the delivery water does not satisfy the delivery set-point (or the
mixing valve set-point, if present) after a delay time that can be set from parameter, the heat
pump/boiler can be activated in winter mode (depending on the settings made) or the chiller is
activated in summer mode.

To regulate the delivery water temperature of the mixing valve and the relative utilities for
heating/cooling of the water, consult the relative paragraphs.

9.1.2 Management of the zone heating/cooling manifolds

(MCZN module)

The zone heating/cooling manifold is activated when:

- Winter functioning mode: the value of the room set-point is lower that the active room set-

point - hysteresis value (differential)

- Summer functioning mode: the value of the room set-point is higher that the active room

set-point + hysteresis value (differential)
Every zone heating/cooling manifold present in the system works independently and, once
activated, generates an activation request of the delivery circulation pump to which it is associated
using the relevant parameter.

9.1.3 Zone work set-point (MCZN module)

The zone work set-point is decided depending on the work mode, manual or automatic (with
programmed weekly time bands), always using the Vgraph zone display.
For the types of work set-point acceptable and for their settings, consult the c-pro CLIMA system
user manual.
Other possibilities also exist to change the work set-point established via Vgraph in the modes listed
below:

9.1.3.1 Variation of the zone work set-point for "climatic curves" (MCZN, MCCT

modules)

By activating the work set-point variation function for “climatic curve”, depending on the external
temperature it is possible (available on the MCCT regulator) to vary the active zone work set-point
value within the minimum and maximum limits that can be set from parameter, in order to adapt the
room temperature to the external climatic conditions, as follows:

- set the minimum and maximum external temperature limits specific for summer functioning

and winter functioning, within which the variation function of the room set-point is active

- the room work set-point minimum and maximum variation values are set

- set the direction of the compensation if direct or inverse for increase or decrease

compensation of the work set-point.

9.1.3.2 Variation of the zone work set-point for "manual compensation" (MCZN

module)

By activating the work set-point variation function for “manual compensation” by installing a
remote set-point variator it is possible (e.g. the EVSET01 accessory), to allow the final user to
increase/lower the active zone work set-point within the pre-established limits, by simply acting on
the pocoveriometer distinguished by the + / - indication.

9.1.4 Zone anti-freeze protection (MCZN module)

During the winter functioning mode when the system is not running (i.e. in OFF state or with time
bands enabled but in a day when the system is off), however an zone anti-freeze protection control
remains active
If the zone room temperature goes below the anti-freeze set-point, the system will however function
(activating the zone manifolds, the circulation pump of the associated delivery line, the heat pump
or the boiler if necessary), in order to guarantee a minimum temperature in the room and so as not
to risk compromising the good functioning of the system due to frozen piping.

Important parameters:

9.1.5 "Heating/cooling integration" function (MCZN, MCDE modules)

If the control of the module for additional dehumidifiers linked to the zone regulator is present and
enabled, then it is possible to activate the "heating/cooling integration" function (also defined with
the term "booster").
This function allows the use of the battery housed in the dehumidifier for the regulation of the room
temperature, via an air system aiding that regularly controlled by the system. This function is used
to compensate the regulation transistors in the system commissioning phase or for passage between
regulation conditions at a distance from each other.

The heating/cooling integration can be summer or winter and is defined as a delta with respect to
the room work set-point. When the room temperature is above/below the room set-point of the delta
value for a continuous time defined by the parameter, then the hot/cold booster activation will be
allowed.
The dependence of integration or booster by one or both zones must be set by assigning functioning
from specific maintenance technical parameter
Setting is separate for hot and cold booster in a way to be flexible to second the temperature
regulation set in the different zones.

In order to check the temperature of the battery housed in the dehumidifier before allowing
activation of the booster, it is possible to activate the presence of a control probe on the MCDE
module (defined as “limit temperature”) and a temperature above/below which to allow the
activation of ventilation.
Moreover, it is possible to decide whether, following activation of the hot/cold booster output, to
force the dehumidifier output or not in ON mode.

9.2 Regulation of the delivery temperature

9.2.1 Management of the delivery circulation pumps (MCCT module)

The thermal power plant can control up to 2 delivery lines, each with relative circulation pump.
As seen in paragraph 9.1.2, each controlled area must be associated to the delivery line by which it
is served.
Via the relevant parameter, the circulation pumps can be managed as follows:

- CONTINUOUS: the delivery circulation pump will remain constantly activated with system

ON and in absence of blocking alarms.

- TEMPERATURE REQUEST: the delivery circulation pump will be activated on request by

at least one of the zone heating/cooling manifolds associated to the delivery line itself.

The activation/deactivation of the circulation pumps will follow the delay times on switch-on/off
established via the relevant parameters.

As well as the request by the zone heating/cooling manifolds, the delivery circulation pumps will be
activated for the following special cycles:

- low temperature protection of the delivery line

- system anti-freeze protection

- anti-grip cycle

The correct functioning of the circulation pumps is controlled via a digital input that can be
configured as pump protection input (block) or delivery flow switch (consult the relative
explanatory paragraph).

9.2.2 Management of the utilities set-up for heating delivery water: boiler (and

heat pump (MCCT module)

During winter regulation, once the water has been put into circulation in the system, whenever the
delivery work set-point is not satisfied, the c-pro CLIMA system will send a request to the thermal
power plant controller for the activation of the utilities set-up for heating of the delivery water.
The MCCT thermal power plant regulator can control two different utilities to heat delivery water.
heat pump and a boiler.
Depending on the type of system, the two heating utilities can be present separately or at the same
time and will be managed in the following way:

• Management of the boiler: whenever the delivery temperature is below the Winter delivery

work set-point of the hysteresis value, then a boiler activation request will be sent.
Correct boiler functioning is controlled via a boiler block digital input which, whenever
activated, will block the utility immediately.

• Management of the heat pump: whenever the delivery temperature is below the Winter

delivery work set-point of the hysteresis value, then a heat pump activation request will be
sent.
Correct heat pump functioning is controlled via a chiller-heat pump digital input alarm
which, whenever activated, will block the utility immediately.

• Management of the boiler and the heat pump: whenever the delivery temperature is below the

Winter delivery work set-point of the hysteresis value, then a heat pump activation request
will be sent.
The heat pump will always have activation priority with respect to the boiler, which will
only be activated in the following cases, at the same time as the deactivation of the heat
pump.

1) Activation of the digital input for chiller-heat pump alarm:

2) External temperature below the value established with the relevant parameter (therefore

for low performance of the heat pump due to the low external temperature)

3) On reaching the number of continuous activation hours of the heat pump

Correct boiler functioning is always controlled via a boiler block digital input which,
whenever activated, will block the utility immediately.

In case N°3, the intervention of the digital input boiler block will cause the automatic reactivation
of the heat pump utility.

9.2.3 Management of the utility set-up for cooling delivery water: the chiller

(MCCT module)

During summer regulation, once water has been made to circulate in the system, whenever the
delivery temperature is above the Summer delivery work set-point of the hysteresis value, then a
chiller activation request will be sent.
Correct chiller functioning is controlled via a chiller-heat pump digital input alarm which, whenever
activated, will block the utility immediately.

9.2.4 Delivery work set-point (MCCT module)

The summer/winter delivery work set-point is established in manual mode in the installation phase
of the system by authorised staff and differs according to the type of system is installed, i.e. due to
High Temperature line (H.T. at radiators) or Low Temperature line (L.T. at floor).
The delivery work set-point corresponds with the effective regulation set-point only when the
mixing valve is not present in delivery.

9.2.5 Output of the delivery mixing valve (MCCT module)

The thermal power plant controller can regulate a mixing valve for every delivery line, via two 0­10V proportional analogue outputs.
If the mixing valve check is enabled, the regulation set-point of the delivery line will be given by
the regulation set-point calculated for the valve
The mixing valve control can be enabled individually for each delivery line.
Normally the mixing valve is used for low temperature delivery lines in high-low temperature
systems.

It is possible to set the functioning mode of the mixing valve for the distinct summer and winter
functioning mode among the following possibilities:

- Valve forced closed: the valve remains always closed during the entire functioning

independently from the system functioning conditions.

- Valve forced open: the valve remains open at the percentage set until the regulation is

active, with regulation off the valve is closed.

- Valve in modulation: the opening of the mixing valve is controlled on the measurement of

the delivery water temperature with respect to the regulation set-point.
In the installation phase it is necessary to set a proportional regulation band and, if
necessary, an integration constant for a PI control, on the basis of system features.

9.2.6 Mixing valve delivery work set-point (MCCT module)

The summer/winter delivery mixing valve work set-point only has effect if the mixing valve is
present and if the modulation valve regulation is enabled.
If the mixing valve check is enabled, the regulation set-point of the delivery line will be given by
the regulation set-point calculated for the valve.

The regulation set-point can be the fixed type or linked to the linear calculation on the external air
temperature measurement.
If the external air temperature probe is present and functioning, the regulation set-point is calculated
according to a climatic curve.
If the external air temperature probe is not present or broken, the regulation set-point is fixed. It is
established via a relevant maintenance level parameter.

The climatic curve for calculation of the set-point envisions the setting of two pairs of External-Set­point temperature values.
This two pairs determine a linearisation line of the two set-point values. All intermediate values
relative to the external temperature conditions included between the minimum and maximum values
set are calculated between the two set-point values.

The two climatic curves and set-points differ due to Summer and Winter functioning modes,
separating the functioning of the valve in the two seasons.

9.2.7 Dew point control (MCCT, MCZN modules)

During the SUMMER functioning mode, the work set-point of the mixing valve (or delivery valve)
will be continuously monitored and if necessary modified in order to check the dew point of each
individual active Zone.

The dew point is the temperature at which a mass of air must be cooled at constant pressure, so that
it becomes saturated (i.e. when the percentage of water vapour reaches 100%) and can therefore
start to condense if further heat is lost.
This would lead to the formation of dew in the cooled floor, thus compromising the integrity of the
controlled room.
Every active Zone, equipped with room temperature and humidity sensor, calculates the
temperature of its own dew point and sends this data to the thermal power plant.

Given the different zones associated to the specific delivery line the thermal power plant regulator
will consider the highest dew point value sent by the individual zones as the dew point of the entire
delivery line.
To consider the construction features of the system, the dew point will be raised by a predefined
offset that can be set by parameter.
The regulation set-point of the mixing valve (or delivery line) will be limited to the minimum value
given by the “delivery dew point + offset” calculated whenever necessary.

Important parameters:

9.2.8 Control of the high and low delivery temperature (MCCT module)

Whenever the temperature of the delivery water exceeds or drops below the minimum and
maximum temperature values accepted for the system of the hysteresis value, then the c-pro mega
MCCT thermal power plant will start special management cycles for these emergencies:

- High temperature protection: the high temperature protection intervention will force the

immediate closure of the mixing valve in order to prevent overtemperatures in the controlled
system, until the temperature returns to the maximum values accepted for the system.

- Low temperature protection: After a fixed delay of 60 seconds, the intervention of the low

temperature protection will cause the activation of the delivery circulation pump in order to
ease heating of the water in the system. The pump will remain on until the minimum
temperature conditions are recovered.

9.2.9 Delivery anti-freeze protection (MCDE module)

During the winter functioning mode when the system is not running (i.e. in OFF state or with time
bands enabled but in a day when the system is off), however an delivery anti-freeze protection
control remains active
If the external temperature goes below the predefined anti-freeze threshold, the system will function
with special circulation pumps activation in order prevent breakage in the system caused by frozen
pipes.

- External temperature lower than 4.0°C: delivery pumps always active;

- External temperature between 5.0 and 1.5 °C: delivery pumps active 10 minutes every 6

hours;

- External temperature over 1.5°C: delivery pumps off

When the external temperature is between -4.0 and -5.0°C the delivery pumps behaviour depends
on the previous situation.

9.3 Regulation of the zone humidity

(MCZN, MCCT, MCDE modules)

9.3.1 Regulation principle

Whenever the function is enabled and a room humidity transducer is present in zone, during
SUMMER functioning mode when the relative humidity detected by the room humidity transducer
is over the active zone humidity set-point value plus the value of the differential, the MCZN
regulator will activate the corresponding manifold/zone dehumidification valve.

Whenever dehumidification makes use of the delivery water for its action (established via the
relative parameter), the activation of the manifold/zone dehumidification valve generates the same
sequence of activations/controls triggered with zone heating/cooling.
For its functioning, consult the zone temperature regulation part.

9.3.2 Management of the dehumidification manifold/valve (MCZN module)

The manifold/zone dehumidification valve is activated when the value of the room relative
humidity is over the active room humidity set-point + hysteresis value (differential).

9.3.4 Management and configuration of the c-pro micro MCDE module for

additional dehumidifiers (MCZN, MCDE modules)

As well as direct control of the manifold/zone dehumidification valve, the c-pro CLIMA system has
the possibility of managing various types of additional dehumidifiers via CANbus, equipped with
utilities (fans/batteries) dedicated to increasing heating/cooling capacities of the controlled system.
To use these types of additional dehumidifiers, the c-pro micro MCDE module must be used.
As previously described, the additional dehumidifiers can be associated to a zone regulator and can
serve just one of the controlled areas (Zone A or Zone B) or both, depending on the type and size of
the controlled rooms.

Depending on the type of dehumidifier used in the system, via the relevant parameter, the c-pro
micro MCDE module assumes a different functioning type, varying the type of utility managed by
the digital outputs, as follows:

Digital outputs configuration

Dehumidif. type 0: DO1 = zone A dehumidifier DO4 = not used
DO2 = not used DO5 = zone A dehumidif. alarm
DO3 = zone B dehumidifier DO6 = zone B dehumidif. alarm

9.4 Regulation of air quality (recirculation)

(MCDE module)

9.4.1 Regulation principle

Whenever at least one regulator for c-pro micro MCDE additional dehumidifiers is present in the
system and whenever the function is enabled, when the level of CO2 detected by the room CO2
transducer is over the CO2 set-point value plus the differential value, the MCDE regulator will
control opening of the room air recirculation damper.

It is possible to control an air circulation damper for every MCDE regulator present in the system.
Every regulation is independent and strictly linked to the reading of the CO2 transducer connected
to the MCDE regulator same.

9.4.2 Management the air circulation damper (MCDE module)

The zone air recirculation damper can be managed in three different ways, depending on the value
set via the relative Damper mode parameter available at the maintenance technician level:

- Open: the damper is kept open independently from the active CO2 regulation.

Total renewal.

- Closed: the damper is kept closed independently from the active CO2 regulation.

Total recirculation.

- Modulating: the damper is opened/closed according to the specific requirements of fresh air

given by the measurements of CO2 in the room.

9.5 Regulation of the DHW tank temperature for the DHW

water

9.5.1 Regulation principle

Whenever the c-pro micro MCPS module is present and enabled in the system, the system will
automatically consider the presence of a DHW storage tank in the system for the DHW.
With the presence of the DHW tank, the temperature regulation principle of the entire system will
change significantly in the following way:

- WINTER REGULATION Via its utilities proposed for heating, the c-pro CLIMA system,

always keeps the DHW tank at the pre-fixed temperature.
The delivery hot water for any heating requests of the Zones is withdrawn directly from the
DHW tank.

- SUMMER REGULATION: Via its utilities proposed for heating EXCEPT the heat pump,

the c-pro CLIMA system, always keeps the DHW tank at the pre-fixed temperature.
The cool delivery water for any cooling requests from the Zones will be supplied by the
chiller unit, obviously without the use of the DHW tank.

9.5.2 Management of the DHW circuit circulation pump (MCPS module)

The MCPS solar panels controller can manage a DHW tank with relative circulation pump.
The circulation pump is activated on temperature request of the DHW tank, whenever the heat
pump or boiler utilities are used to heat the DHW. When the use of the solar panel circuit/s for
heating is sufficient, the DHW circulation pump will not be used.

The activation of the DHW circulation pump will follow the delay times on switch-on established
via the relevant parameter.

As well as the request by the DHW tank, the DHW circulation pump can be activated during a
special anti-grip or antilegionella cycle.

The correct functioning of the circulation pumps is controlled via a digital input that can be
configured as pump protection input (thermal switch) or delivery flow switch (consult the relative
explanatory paragraph).

9.5.3 DHW tank work set-point (MCPS module)

The DHW tank work set-point is established in manual mode from the relevant Set-point menu
present in the main menu of the c-pro micro MCPS regulator.
Depending on the dimensions of the system, the DHW tank can have just one temperature probe
(DHW tank probe) or two different temperature probes (DHW tank upper and lower probe).
If the DHW tank works with two probes, temperature regulation will be satisfied when both the
lower water temperature and the upper water temperature have reached the work set-point value set.

The regulation differential of the DHW tank is fixed and corresponds to -1°C.

9.5.4 Management of the AUX1 auxiliary circuit circulation pump

(MCPS module)

The MCPS solar panels controller can manage an AUX1 hot water auxiliary circuit with relative
circulation pump.
Via the relevant parameter, the circulation pump can be managed as follows:

- CONTINUOUS: the auxiliary circuit circulation pump will remain constantly activated with

system ON and in absence of blocking alarms.

- TEMPERATURE REQUEST: with heating request by the AUX1 circuit (depending from

work set-point and differential), when the temperature of the DHW tank or of the solar
panels circuit (depending on the value of Control probe parameter) is over a value set by the
(Offset ON) parameter at the temperature of the AUX1 circuit, then the AUX1 water
circulation pump will be switched on, in a way to contribute with the heating of the AUX1

circuit.
Whenever the difference between DHW tank (or solar panels circuit) temperature and AUX1
becomes lower than a value set by (Offset OFF) parameter, the AUX1 circulation pump will
be switched off.

For the temperature regulation to be effective, it is necessary for the work set-point of the auxiliary
circuit to be lower than the DHW tank work set-point.

As well as the request by the AUX 1 circuit, the solar panels circuit circulation pump
will be activated for the following special cycles:

- auxiliary circuit low temperature protection

- anti-grip cycle

The correct functioning of the circulation pump is controlled via a digital input that can be
configured as pump protection input (thermal switch) or delivery flow switch (consult the relative
explanatory paragraph).

N.B.
The AUX1 auxiliary circuit can be managed only in systems with individual heating solar panels
circuits. If this is not the case, all other enablings and settings made will have no effect.

(MCPS module)

Whenever the temperature of the AUX1 auxiliary circuit water exceeds or drops below the
minimum and maximum temperature values accepted for the system of the hysteresis value, then
the c-pro micro MCPS solar panels regulator will start special management cycles for these
emergencies:

- High temperature protection: the high temperature protection intervention will trigger a

simple signal to the maintenance staff.

- Low temperature protection: the low temperature protection will trigger the activation of the

circulation pump of the auxiliary circuit in order to ease heating of the circuit water. The

pump will remain on until the minimum temperature conditions are recovered.

9.5.6 Management and setting of the periodic antilegionella cycle for the DHW

tank (MCPS module)

In order to disinfect the DHW tank from the proliferation of legionella bacteria due to the deposit of
DHW, the c-pro CLIMA system envisions the periodic management of anti-legionella cycles.
Depending on the type of system, it is possible to select daily, weekly or monthly antilegionella
cycles.
An anti-legionella cycle consists in taking, the temperature of the DHW tank to a temperature such
to destroy bacteria (standard to 70°C, but which can be set from parameter) for a long enough
period of time (standard at 60 minutes, but can be set from parameter) by activation of the boiler
and the DHW circulation pump.
These periodic cycles will help with respect to the Standards in force on the subject.

9.6 Management and configuration of the heating solar panel

circuits (MCPS module)

Whenever the c-pro micro MCPS module for solar panels is present and enabled in the system, one
or two heating solar panel circuits management can be enabled, with the function of heating the
DHW in the DHW tank.

The heating solar panels circuits will be added to the other utilities set-up for heating the DHW
tank, with PRIMARY importance with respect to the other utilities, with the following functioning
principle:

- with heating request by the DHW tank, when the temperature of the solar panels circuit is

over a value set by the (Offset ON) (ON Offset) parameter at the temperature of the DHW

tank, then the solar panels circuit will start its own water circulation pump, in a way to

contribute with the heating of the DHW tank.
Whenever the contribution of the solar panels circuits is sufficient to reach the DHW set­point, at this point the solar panels circuit circulation pump will be switched off.
Whenever the difference between solar panels and DHW tank temperature becomes lower
than a value set by ( OFF Offset) parameter, the solar panels circulation pump will be
switched off and the other utilities set-up for heating will be activated (heat pump or boiler,
with the rules and times described in the previous points), in order to reach the work set­point set for the DHW tank.

The two measurement inputs set-up to read the temperatures of the two circuits are the
4-20mA type. Therefore it is necessary to be equipped with a temperature transducer with 4-20mA
output or a converter able to convert the value read by the temperature probe into a
4-20mA signal.
For this purpose, EVCO suggests the use of the EVCONV01 accessory, i.e. a Pt100 / 4-20mA
converter able to convert the signal coming from the Pt100 3 probe wires at input into a 4-20mA
signal compatible with the c-pro micro MCPS measurement inputs.

The presence of the second circuit of solar hating panels automatically disables the presence of the
AUX1 auxiliary circuit and of the management of the anti-stagnation emergency in Tenda2
(Cover2) mode.

9.6.1 Management of the solar panels circuits circulation

(MCPS module)

The controller for the MCPS solar panels can manage up to 2 thermal solar panel circuits, each with
relative circulation pump.
The circulation pump is activated on temperature request of the DHW tank, whenever the
conditions described in previous paragraph 9.5.4. are satisfied.

As well as the request by the DHW tank, the solar panels circuits circulation pumps
will be activated for the following special cycles:

- periodic activation cycle for uniformity of temperatures

- solar panels circuits low temperature protection

- anti-stagnation emergency

- anti-grip cycle

The correct functioning of the circulation pumps is controlled via a digital input that can be
configured as pump protection input (thermal switch) or delivery flow switch (consult the relative
explanatory paragraph).

9.6.2 Control of the high and low temperature of the solar panel circuits (MCPS

module)

Whenever the temperature of one of the solar panels circuits exceeds or drops below the minimum
and maximum temperature values accepted for the system of the hysteresis value, then the c-pro
micro MCPS solar panels regulator will start special management cycles for these emergencies:

- High temperature protection: after a fixed delay of 60 seconds, the high temperature

protection intervention will start an anti-stagnation emergency cycle (described in the

following paragraph), in order to dispose of the overheated water and to take the

temperature of the water back within the system safety conditions.

- Low temperature protection: after a fixed delay of 60 seconds, the intervention of the low

temperature protection will cause the activation of the solar panels circuit circulation pump

in order to ease heating of the water in the circuit. The pump will remain on until the

minimum temperature conditions are recovered.

9.6.3 Management and setting the stagnation emergency for solar panels

circuits (MCPS module)

Whenever the temperature of the water in one of the solar panels circuits exceeds the maximum
temperature value accepted for the system of the hysteresis value, then the regulator for c-pro micro
MCPS solar panels will start a special stagnation emergency cycle.
The emergency condition must remain at least for a fixed time of 60 seconds and will be managed
in the following way, according to the value set for the Stagnation emergency parameter:

- ON/OFF: the stagnation emergency will be managed via the activation of a solenoid vent

valve, which will dispose of the hot water.

The heat disposal relay will remain enabled until the temperature of the solar panels circuit

has gone back below the maximum temperature value accepted of the hysteresis value

(differential).

As well as the heat disposal relay, the circulation pump of the corresponding solar panels

circuit is activated at the same.

- Cover1: the stagnation emergency will be managed by the opening of a motorised cover

(servomotor with spring return) which will cover the surface of the solar panels from solar

exposure.

The cover opening relay will remain enabled until the temperature of the solar panels circuit

has gone back below the maximum temperature value accepted of the hysteresis value

(differential).

As well as the cover opening relay, the circulation pump of the corresponding solar panels

circuit is activated at the same.

- Cover2: the stagnation emergency will be managed by the opening/closing of a motorised

cover (servomotor with separate opening and closing controls) which will cover the surface

of the solar panels from solar exposure.

The cover opening relay will remain enabled until the temperature of the solar panels circuit

temperature has returned below the maximum temperature value accepted of the hysteresis

value (differential). If this is not the case, the cover closing relay will remain active for all

periods in which the cover must be closed.

As well as management of the cover opening/closing relays, the circulation pump of the

solar panels circuit is activated at the same.

N.B.
Setting the parameter at the Cover2 value will not have any effect if the system has been configured
to manage the second solar panels circuit or if the Aux1 auxiliary circuit is present.

9.7 Other regulations

9.7.1 Management and setting of the periodic anti-grip cycle

(MCCT, MCPS modules)

The function has the purpose of preventing the blocking of the pumps and valves present in the c­pro CLIMA system during system standstill due to any deposits present in the system or due to the
formation of crystalline aggregates (lime scale or other) on the mechanical seals of the pumps and
valves.
The function automatically activates all pumps and valves in sequence once a week, which have
been at a standstill for at least a week.
The day and time of weekly activation can be set by the user via the relevant Maintenance
technician parameters.
The sequence scans the various utilities in the system every minute (pumps and valves): the cycle
leads to the activation of the element considered for 30 seconds.

The enabling and setting of the periodic anti-grip cycle is set separately on the thermal power plant
c-pro mega MCCT controller and on the c-pro micro MCPS module for solar panels, respectively
for the following utilities:

MCCT regulator anti-grip : delivery 1 circulation pump if enabled from parameter
delivery 1 mixing valve if enabled from parameter

delivery 2 circulation pump if enabled from parameter
delivery 2 mixing valve if enabled from parameter

MCPS regulator anti-grip : DHW circuit circulation pump always enabled

9.7.2 Management of the circulation pumps protection digital input

(MCCT, MCPS modules)

Every circulation pump present in the c-pro CLIMA system has a protection digital input.
Every protection digital input linked to a circulation pump can be associated to one of the following
functionalities, depending on the value selected via the relevant parameters.

- THERMAL SWITCH: every activation of the digital input will cause the immediate

deactivation of the relative circulation pump.

Once the digital input is deactivated, the circulation pump will start to work according to its

own regulation (automatic rearm).

Page 86

C-PRO CLIMA SISTEMA INSTALLER MANUAL

- FLOW: every activation of the digital input, after a delay time or from the activation of the

pump (start) or from the activation of the input itself (normal conditions), will cause the

deactivation of the relative circulation pump.

Once the digital input is deactivated, the circulation pump will start to work according to its

own regulation (automatic rearm) unless the maximum number of flow switch alarms is not

reached for automatic rearm, however the deactivation of the alarm will be possible only

with manual procedure (manual rearm).

The regulation parameters relative to the delivery 1 and 2 circulation pumps are present in the
MCCT thermal power plant controller while the parameters relative to the circulation pumps of the
auxiliary DHW circuit, solar panels 1 and 2 are present in the MCPS controller for solar panels.

9.7.3 Manual functioning mode

(MCCT, MCZN, MCDE, MCPS modules)

The c-pro CLIMA system allows to set manual functioning for the various uses.
In this state the devices are not governed by the automatic functions, but are however sensitive to
any alarms.
The manual activation of the devices replaces the regulation for the determined device, therefore
from now on gives origin to all automatic controllers for the activation of the system.
For example, if the zone valve is controlled manually, it will be interpreted by the system as
thermostatic activation causing the activation of the relative delivery circulation pump, the mixing
valve and the boiler/chiller etc.
The manual functioning of the devices is useful for the execution of functional tests on system start­up or in case or probe breakage or other.
