1 GENERALITIES

1.1 Description

The climatic modules of the c-pro 3 CLIMA sistema series are devices studied for the air conditioning and the heating

of buildings.

They make use of the programmable controllers belonging to the c-pro 3 series and of the user interfaces belonging

to the same series.

They are available in built-in and in blind version with remote user interface (according to the kind of module).

They can be powered both in alternating and in direct current (24 VAC/20... 40 VDC).

The modules allow realizing an expandable and modular control device network distributed in the main rooms of the

building reducing the wiring work to a minimum: the modules c-pro 3 hecto MCCT can manage the thermal power

plant, the c-pro 3 hecto MCZN ones the air conditioning and the heating of two zones instead and the c-pro 3 hecto

MCPS ones finally the thermal solar panels.

The central module thermal MCCT is indispensable for the functioning of the system, it can be connected from one to

eight zones MCZN control modules, each of which can handle up to a maximum of six zones.

In total, thanks to this system can be operated up to a maximum of 48 zones in temperature and humidity.

The user interfaces can easily be integrated in residential and commercial rooms (at the front of the interfaces it is

possible to apply the plates CPVP or the plates belonging to the series “Living” and to the series “Light” Bticino).

All the modules have communication ports (programming, CAN, RS-485, with MODBUS communication protocol, etc.).

Through the programming port it is possible to make the upload and the download of the configuration parameters

(using the programming key EVKEY10); through the RS-485 one, with MODBUS communication protocol, it is possible

to connect the devices to the set-up software system Parameters Manager or to the plants monitoring and supervision

one RICS (through a serial interface) instead.

Through the CAN communication port it is possible to connect the devices among them.

3.3.3 Return temperature control

The return temperature is monitored so as to avoid, for example in summer mode, that if cooling is required and the

water that arrives at Vmix is hot heads are activated by heating the environment rather than cool it. A check is done

after verifying that a time from the opening of the parameter Vmix the return water temperature (in cold weather) is

not higher than the flow temperature setpoint active plus a delta parameter, in case of higher temperature will be the

Vmix closed and an alarm signaled the return temperature. Conversely for the heating mode, the return temperature

should not be lower than the flow temperature setpoint less active as a delta parameter.

3.3.4 Richiesta Chiller/pompa di calore

You have the option of dehumidification with cold water or not regulated and enabling command request chiller / heat

pump based on the regulation band / opening Vmix MAX / MIN opening Vmix.

The zone regulator leaves the factory configured as zone 1 module (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 module 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

3. Enter the Installer  General parameters menu

4. Set the number of local zones managed by the MCZN regulator

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

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

second zone regulator is connected (zone 2 regulator).

3.4.3 MCPS solar panels controller network configuration

The controller for solar panels MCPS is the sole controller of this type can be installed in the plant, for its configuration

will be sufficient to enable the presence of the regulator MCPS by the application of thermal power plant, with the

following procedure:

1. Enter the Installatore  Parametri generali (Installer, General parameters) menu of the MCCT regulator

2. Enable the presence of the MCPS regulator in the system

3.5 Displays network configuration

For the final user, the c-pro 3 CLIMA sistema 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 Vgraph (maximum n°1 display for the entire system)

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

• Zone private terminal

Depending on the type of terminal desired, settings must be made in the MCZN zone controller and in the Vroom user

terminal, illustrated in the following paragraphs.

3.5.1 Public terminal

If the viewer is configured as a terminal Vgraph public (universal), will be able to view all zone controllers MCZN in

the system and all areas managed by the controllers MCZN to 6 zones.

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).

5.13 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 relative controlling On/Off key from digital input (parameter PH2)

Switch-on: close contact of the remote On/Off: If all other conditions are enabled, the machine switches to

"ON".

Switch-off: if the contact of remote On/Off is open, the machine switches to "OFF from digital input" (marked

with the words "OFF in. Digital").

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.

page 36 of 74

Page 37

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

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:

- PH02: Enables the function

- PH34 : Sets the NC, NO logic for the digital contact

5.13.1 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 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.

5.14 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 3 CLIMA sistema 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 PH03)

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 Summer/Winter from digital input control PH03

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

functioning mode.

4) Using Summer/Winter automatic switch-over function PH03

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

value established with the PH05 parameter for the time established by the PH06 parameter

Conversely, switch-over from winter to summer takes place when the external temperature remains below

the value established with the PH04 parameter for the time established by the PH06 parameter

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

page 37 of 74

Page 38

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

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.

8 Regulations

In this chapter you will find all the major adjustments made by the c-pro 3 CLIMA sistema.

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.

8.1 Regulation of the zone temperature

8.1.1 Regulation principle

Depending on the system functioning mode (summer or winter) and the time band active in every zone regulated by

the system (manual, night, holiday, economy, comfort in summer and manual, anti-freeze, comfort in winter), when

the temperature detected by the room probe is over (summer) or below (winter) the active zone set-point value plus

(MCZN, MCCT modules)

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

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 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.

8.1.2 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.

There is also the adaptive management of valve, this feature allows you to disable the valve in advance of the zone

temperature setpoint temperature is reached, so as to guarantee an optimal comfort zone avoiding excessive

temperature fluctuations as well as switching in advance.

8.1.3 Fan Coil

In the case of fan coil system that provides a setting other than serving both in temperature and moisture (summer

mode). For the characteristics of the zone module it is possible to predict the speed control of the fans is a 3-step is

modulating.

Are manage the following loads:

- ON-OFF water valve (one for heating/cooling) or free water – cooling function / dehumidification

- ON-OFF hot water valve – heating / post-heating function

- Post-heating electric coil / heating support – dehumidification / heating function

- 3 fan speed – cooling / heating / dehumidification function

- Modular fan speed regulation – cooling / heating / dehumidification function.

Depending on the configuration will be activated on the valve as a function of the set and of the control band. May also

be activated also the electric battery configured as support for the heating according to its own offset and a delay for

the activation of the resource.

Both the cooling and the dehumidification will be activated, according to its set and individual regulation proportional

band, the cold water valve. To manage the dehumidification request when there is not request of cooling, there will be

the following possibilities:

page 58 of 74

Page 59

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

If it is NOT configured an electric battery or hot water with the function of post-heating the request of temperature or

humidity will take precedence in accordance with the priorities defined by parameter. If it IS configured a battery

electric or hot water function with re-heating it will be activated to prevent excessive cooling environment.

The post heating will be activated when it is in stock the dehumidification function without cooling demand.

Will be deactivated with the request for activation of the dehumidification or cooling demand.

The fan could be 3 speed or modulare and will be pilot as the figure:

For the ventilation 3 step activation will be divided the proportional band in equal parts (will be the same of the zone

valve).

8.1.4 Zone work set-point (MCZN module)

The working setpoint of the area is decided, depending on the working mode, either manually or automatically (time

slots scheduled weekly), again through the use of the viewer area Vroom.

There are also the additional possibility of changing the working setpoint established by MCCT, in the ways listed

below.

8.1.4.1 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.

8.1.4.2 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 EVTP010V01 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.

Remote set-point variator

EVTP010V01

The system installer/maintenance technician must enable and set the function features from parameter, i.e.:

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

- enable and set the presence of the remote set-point variator

- calibrate the movement of the potentiometer for 3 basic positions, i.e. maximum negative variation, neutral

(0°C variation) and maximum positive variation.

Calibration procedure

8.1.5 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.

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

8.1.6 "Heating/cooling integration" function (MCZN modules)

You can activate the "auxiliary heating/cooling" (also referred to by the term "booster").

This function allows the use of the battery housed in the dehumidifier for adjustment of temperature, through an air

system in support of that regularly checked by the system. This function is used to compensate for the transient

adjustment in steps of first heating up or adjustment conditions for switching between very distant from each other.

The auxiliary heating/cooling may be summer or winter, and is defined as a delta from setpoint work environment.

When the ambient temperature is above/below the temperature setpoint of the delta value for a continuous time

defined by parameter, then you will be given the activation of the booster hot/cold.

Should be set to the dependence of integration or booster by one or more zones by assigning the function from

specific parameter maintainer.

The setting is separate for hot and cold booster in order to be flexible to accommodate the adjustment of the set

temperature in the different zones.

8.2 Regulation of the delivery temperature

(MCCT modules)

8.2.1 Management of the delivery circulation pumps (MCCT module)

The controller of thermal power station is able to handle up to 6 delivery lines, each with the corresponding circulation

pump.

As previously mentioned, each controlled area should be associated with the discharge line from which it is served.

Through the appropriate parameter circulation pumps can be operated in the following way:

- CONTINUOUS: the circulation pump discharge will remain continuously active system with ON and

no alarms blockers.

- REQUEST FOR TEMPERATURE: the circulation pump discharge will be activated at the request of at least one

of the manifolds heating/cooling zone associated with the discharge line itself.

The activation / deactivation of circulating pumps will follow the timing delay at power on / off established through the appropriate parameters.

In addition to the demand from collectors for heating / cooling zone, the circulation pumps discharge will be activated for the following special cycles:

- Protection of low temperature flow line

- Frost protection system

- Cycle anti-grip

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).

8.2.2 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 3 CLIMA sistema 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 request will remain active until the satisfaction of the set point or stays open until the mixing valve (selected by

parameter PL05 ). If PL05 = 0 , the demand for hot/cold is deactivated to the achievement of the set flow; PL05 if = 1,

the demand for hot/cold is switched off with a delay defined by parameter PL06, complete closure of the mixing valve.

The regulator of central heat MCCT is able to control two different utilities for heating water flow : heat pump and a

water heater.

Depending on the type of system the two utilities of heating may be present separately or simultaneously and will be

handled in the following way:

page 61 of 74

Page 62

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

• Management of the water heater (boiler): correct operation of the boiler is controlled by a digital

input block heater that, if activated, will immediately block the user

• Management of the heat pump : the correct operation of the heat pump is controlled by a digital

input alarm chiller-heat pump that, when activated, will immediately block the user.

• Management of the water heater and the heat pump, the heat pump will always have priority with

respect to the activation of boiler, which will be activated in the following cases, simultaneously

with the deactivation of the heat pump:

1) Activation of digital input alarm chiller-heat pump

2) Outdoor temperature below the set value with the appropriate parameter (for then poor performance of the

heat pump due to low outdoor temperature)

3) Achieved number of hours of continuous activation of the heat pump

The correct operation of the boiler is always controlled via the digital input block heater that, if activated, will

immediately block the user.

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

utility.

8.2.3 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.

8.2.4 Delivery work set-point (MCCT module)

The working setpoint discharge summer/winter is set to manual mode during installation of the system by authorized

personnel.

The working setpoint flow corresponds to the actual setpoint adjustment only in the case in which there is no flow in

the mixing valve.

8.2.5 Output of the delivery mixing valve (MCCT module)

The thermal power plant controller can regulate a mixing valve for every delivery line, via two 0-10V 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.

page 62 of 74

Page 63

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

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.

8.2.6 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-Set-point 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

8.2.7 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.

8.2.8 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 3 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.

8.3 Regulation of the zone humidity

(MCZN, MCCT modules)

8.3.1 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.

8.3.2 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).

8.3.2.1 Valve closed in advance

This function (enabled from the parameter), thanks to a self-learning allow to disable the valve zone temperature early

with respect to the setpoint temperature is reached, so as to ensure optimum comfort zone avoiding excessive

temperature fluctuations.

8.3.3 Zone humidity work set-point (MCZN module)

The zone humidity work set-point is decided in manual mode via the relative maintenance technical parameters

present in the MCZN module or automatically, set by the final user via programmed weekly time bands.

To set the automatic humidity work set-points (Economy and Comfort set-points), consult the c-pro 3 CLIMA sistema

user manual.

Page 65

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

8.3.4 Management of digital on/off dehumidifier

The zone controller c-pro 3 hecto MCZN has two digital inputs (one for each zone) on/off dehumidifiers.

If the digital input is at logic level "disabled", the corresponding additional dehumidifier will be considered in the OFF

state and all of its settings are disabled.

In order to make such control active, the inputs must be activated through the appropriate parameters maintainer.

8.4 Regulation of the DHW tank temperature for the DHW

water

(MCPS module)

8.4.1 Regulation principle

Whenever the c-pro 3 hecto 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 3 CLIMA sistema, 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 3 CLIMA

sistema, 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.

8.4.2 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).

page 65 of 74

Page 66

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

8.4.2.1 DHW circuit circulation pump management (MCPS module) with setpoint

panel mode.

The controller for solar panels MCPS is able to manage a DHW tank with circulation pump.

The circulation pump is activated by temperature request of the DHW tank (upper DHW tank probe), if are used for

domestic water heating the heat pump or the boiler.

The pump activation of DHW circulation pump follows the power on delay time established by the appropriate

parameter.

In addition to the request of the DHW tank, the DHW circulation pump can be activated during a spcial anti-grip or

antilegionella cycle.

The correct functioning of the circulation pumps is controller by a digital input which can be configured as pump

protection or supply flow-switch.

8.4.3 DHW tank work set-point (MCPS module) With DHW setpoint

mode

The DHW working setpoint is manual established from the setpoint menu on the c-pro 3 hecto MCPS main menu.

According to the plant dimensions, the DHW tank can use only one temperature probe (DHW tank probe) or 2

temperature probes (upper and lower DHW tank probes).

If the DHW tank use two probes, the regulation of the temperature will be made when the lower and the upper water

reaches the working setpoint.

The DHW tank regulation differential is fixed and is -1°C.

8.4.3.1 DHW tank working setpoint (MCPS module) with panels setpoint type

The DHW tank working setpoint is manual established from the setpoint menu in the c-pro 3 hecto MCPS module

main menu.

The regulation of the temperature will be made when the upper DHW tank water reaches the working setpoint.

The DHW tank regulation differential is fixed and is -1°C.

8.4.4 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.

page 66 of 74

Page 67

Evco S.p.A. c-pro 3 CLIMA sistema | Installer manual ver.1.1 | Code 144CP3CSE114

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.

8.4.5 Control of the high and low temperature of the auxiliary circuit

AUX1 (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 3 hecto 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.

8.4.6 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 3 CLIMA sistema 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.

8.5 Management and configuration of the heating solar panel

circuits (MCPS module)

8.5.1 With DHW setpoint

Whenever the c-pro 3 hecto 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 set-point, 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 set-point set for the DHW tank.

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.

8.5.2 con tipo setpoint pannelli

If it is present and enabled in the plant the c-pro 3 hecto MCPS module for solar panels, is possible to enable the

management of one or two circuits of solar panels, with the fuction to heat the the domestic water of the DHW tank.

The heating panel circuit will be added to the other heating loads of the DHW tank, with integrative priority on other

loads, with the following functioning:

- with heating request from the DHW tank, when the temperature of the solar panels circuit is higher of a set

value (Offset ON) of the lower temperature od DHW tank, the solar panel circuit will start the water

circulation pump, to help to the DHW tank heating.

If the difference between the solar panel temperature and the DHW tank lower temperature is lower than the

value set by parameter (Offset ON), the solar panels water circulation pump will stop.

The presence of the second solar panel circuit will automatically disable the presence of the AUX1 auxiliary circuit and

the emergency anti-stagnation in Tenda2 mode.

8.5.3 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).

8.5.4 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 3 hecto 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.

8.5.5 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 3 hecto 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.

8.6 Other regulations

8.6.1 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 c-pro 3 CLIMA

sistema 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 3 mega

MCCT controller and on the c-pro 3 hecto 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

AUX1 circuit circulation pump always enabled

solar panels 1 circuit circulation pump always enabled

solar panels 2 circuit circulation pump always enabled

8.6.2 Management of the circulation pumps protection digital input

(MCCT, MCPS modules)

Every circulation pump present in the c-pro 3 CLIMA sistema 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).

- 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.

8.6.3 Manual functioning mode (MCCT, MCZN, MCPS modules)

The c-pro 3 CLIMA sistema 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 start-up or in case or

probe breakage or other.
