1.- ¿How is the net configured? (How many units can be connected, which are the combination, what is needed by the
interface?)
The purpose of this net is connecting one or more units Ecolean to a BMS system. To get this we use the interface KP06. Up to 8
units can be connected (depending sizes and characteristics), to an interface KP06. We can connect up to 15 KP06 to the net.
In each Ecolean unit, is necessary to install a BUS adapter to convert the control (TTL) system in a signal RS-485.
We can connect in the net different controllers (as Climatic, Ecolean), but in a KP06 we can connect only controllers of the same
type.
2. - ¿What can be controlled by this net?
With this system, we can manage the following options in each of Ecolean units:
- Select between OFF/STAND-BY/COOL/HEAT.
- Modify the cooling / heating setpoint
- Read the limitations in the unit, as the functioning of the heat pump, the maximum setpoint, and minimum setpoint. .
- Read all the alarm status.
- Read inlet water temperature , outlet water temperature, condensing temperature and outdoor temperature ( this last one only
if the unit is fitted with the dynamic setpoint option)
- Read inlet signals status (pressostats, water flow switch, thermal relays motor protections).
- Read the outlet signal status (compressor, fan, water pump ...).
3. - Fitting instructions.
It is necessary to include in every installation:
One Bus Adapter by each of the units
One KP06 at least by every 8 units
Bus Adapter will be delivered installed inside the Ecolean unit (electrical board), with the power supply taken from the general
power supply of the unit, and the control connection made. KP06 is delivered loose, for later installation in the most adequate
place.

4. - Connections
This sample could be the Standard connection of a KP06 net with a BMS system with a RS485 connection. It is also possible to
connect with a BMS net or a computer provided with a RS232 connection, but in this case there can be only one KP06 and the
connection cannot be longer than 15 meters (see KP06 details for further details)
Connections between KP06
KP06 configuration
- Connection between the BMS system and the KP06 must be done
according the figure besides, taking into account the following
indications :
- The wiring has to be done according local normatives.
- Every KP06 have to be supplied with 230 Vac/50 Hz + PE
(15%). Use a cable with a 1.5 mm2 section.
- Maximum length of the RS485 net (from the BMS system to the
last) is 1.000 m.
- BMS connection is RS 485. It has to be connected to the port
RS 485 of BMS with every KP06 in parallel.
- It is advisable to use screened cable with a 0.5 mm2 for this
type of connection.
- Jumpers J8 y J9 of the connected KP06 to the Ecolean units should
be connected in 1-2 position.
- Switch SW2-1 of every KP06 should be in ON-OFF position, except
the last one that has to be in ON position.
- Switches SW1-7 y 8 is used to configurate the transmission speed
according the following table.
Configurate the other switches SW1 as the figure resides.

c) Connections between KP06 and Ecolean units.
- In every Ecolean unit there is a Bus Adapter. In this Bus Adapter a power supply connection has been done, as well
as the control connection in the Ecolean unit.
- Connection between KP06 and the Ecolean unit , has to be done as shows the figure taking into account the
following indications:
- Maximum length for the RS485 net (from the KP06 to the last ECOLEAN unit) is 2000 m.
- Wiring has to be done according the local normatives.
- Screened cable of 0.5 mm2 is advisable.
(for example cable model Belden 8762 with PVC isolation , cable plus metallic screen , 20 AWG, nominal capacity between cables of 89
pF, nominal capacity between a cable and the metallic screen of 161 pF)..
- Use the cables to connect + and - and the screen to connect GND.
- In each Bus Adapter of the last Ecolean, connect a 120 ohms resistance 1/4w between + and - .
- Each Ecolean unit connected to a KP06 has a different address between 1 and 8 .This address is introduced in the
controller.

5.b Detailed information about CLIMATIC 200 parameters
00H, 01H parameters (readable and writable)
This parameter defines the setpoint which the unit will function with , in cooling mode ( parameter 00 H ) or heating mode (
01H) .
¡Important : The value of the desired temperature has to be multiplied by 10!
Introduced values for this parameter have to be within the range between minimum setpoint ( Parameter 82 H cooling / 80 H
heating ) and the maximum setpoint ( Parameter 83 H cooling / 81 H heating ) .
¡Important: if the unit Works out of this range of temperatures , unit can work suffering critical damages !
If the unit is cooling only , there is no sense in using 01H parameter . This possibility can be restrained with the parameter 84 H
, which shows with the value 1 if the unit is heat pump version .
Example : H00=110 and H01=430 shows the cooling setpoint 11.0ºC and the heating setpoint 43.0ºC

02H parameter (readable and writable)
This parameter defines the functioning of the unit according the following :
Parameter 02H=00H ∧Stopped unit
Parameter 02H=04H ∧Stand- By mode
Parameter 02H=05H ∧Cooling only mode
Parameter 02H=06H ∧Heating pump mode
¡Important. If values different from 0 are used, they may appear wrong values!
To know if the unit can work as a heat pump , parameter 84 H has to be read.
¡Important : if in a cooling only unit , heat pump mode is demanded , unit can work suffering critical damages!
80H, 81H, 82H, 83H parameters (only readable)
Limits of cooling setpoint and heating setpoint:
80H ∧Maximum heating setpoint
81H ∧Minimum heating setpoint
82H ∧Maximum cooling setpoint
83H ∧Minimum cooling setpoint
Use these values to establish the limits values for the parameters 00H y 01H.
84H (only readable)
Shows a 0 value if the unit is cooling only , and a 1 value if the unit is heat pump .
Use these value to establish if it is posible to modif. The heating setpoint ( H01 parameter ) and it is more important to know if it
can be switched in heat pump mode ( H02 parameter)
85H, 86H, 87H, 88H, 89H, 8AH, 8BH, 8CH parameters (only readable)
In this parameters we can read the values measured by different temperature sensors of the unit.
85H ∧Water inlet temperature (MSB)
86H ∧Water inlet temperature (LSB)
87H ∧Water outlet temperature (MSB)
88H ∧Water outlet temperature (LSB)
89H ∧Refrigerant piping temperature (MSB)
8AH ∧Refrigerant piping temperature (LSB)
8BH ∧Outdoor temperature (MSB)
8CH ∧Outdoor temperature (LSB)
Nota: The outdoor temperature will only show the correct values if the outdoor temperature sensor is included. (dynamic
setpoint kit )
To calculate the value , we have to take into account the following value:
ºC·10= MSB·256 + LSB
Example : in 85H we can read value 1 and in 86H value 172. This means 1 * 256 + 172=428. The water indoor temperature
sensor is showing a value of 42.8ºC.

5.d.2 /Analogical parameters/
00H, 01H (readable and writable)
This parameter defines the setpoint which the unit will function with in cooling ( 00H parameter) or in heating ( 01H parameter)
¡Important: Value of the required temperature has to be multiplied by 10!
Values included in this parameter must be within the range from the minimum setpoint ( 82H parameter for cooling / 80H for
heating) and the maximum setpoint ( Parameter 83H for cooling / 81 H for heating) .
¡Important: if the unit Works out of this range of temperatures, the unit may work with critical damages!
If the unit is a cooling only unit , there is not sense in using 01H parameter. We can limit this possibility with the 84 H parameter
which with the value 1 shows that the unit is heating pump version .
Example: H00=110 and H01=430 shows cooling setpoint 11.0ºC and heating setpoint 43.0ºC
02H parameter (readable and writable)
This parameter defines the function of the unit as following :
Parameter 02H=00H ∧Stopped unit
Parameter 02H=80H ∧Stand-By mode
Parameter 02H=81H ∧Cooling only mode
Parameter 02H=82H ∧Heat pump mode
¡Important: If different values are used , the result obtained maybe wrong!
To know if the unit can work in heat pump mode , read the value of the 84 H parameter.
¡Important: If in a cooling only unit , heat pump mode is demanded , the unit may work with critical damages!
80H, 81H, 82H, 83H parameters(only readable)
Cooling and heating setpoint limits, in detail :
80H ∧Maximum heating setpoint
81H ∧Minimum heating setpoint
82H ∧Maximum cooling setpoint
83H ∧Minimum cooling setpoint
Use these values to establish the limit values of the parameters 00 H and 01 H.
84H (only readable)
Shows with a value 0 if the unit is cooling only or with a value 1 if the unit is heat pump mode.
Using this value can establish if it is possible to modify the heating setpoint (H01 parameter) and more important also if we can
change to heat pump mode (H02 parameter)

Note: Outdoor temperature will only show correct values if the unit is fitted with the outdoor temperature sensor (dynamic
setpoint kit)
Example: in 85H we will read the value 428, so the inlet water sensor is showing the value 42.8ºC.
8AH, 8BH, 8CH, 8DH, 8EH, 8FH, 90H, 91H, 92H, 93H parameters (only readable)
In these parameters we can read the hours of functioning of different components, in detail:
8AH ∧Hours of functioning of compressor 1 (MSB)
8BH ∧Hours of functioning of compressor 1 (LSB)
8CH ∧Hours of functioning of compressor 2 (MSB)
8DH ∧Hours of functioning of compressor 2 (LSB)
8EH ∧Hours of functioning of compressor 3 (MSB)
8FH ∧Hours of functioning of compressor 3 (LSB)
90H ∧Hours of functioning of compressor 4 (MSB)
91H ∧Hours of functioning of compressor 4 (LSB)
92H ∧Hours of functioning of water pump (MSB)
93H ∧Hours of functioning of water pump (LSB)
To calculate the value, the following formula has to be taken into account:
HR= MSB·256 + LSB
Example: in 8AH we can read the value 2 and in 8 BH a value of 48. This means 2 * 256 + 48=560. This shows that
compressor 1 has worked 560 hours.
94H, 95H, 95H, 96H, 97H, 98H, 99H parameters (only readable)
In these parameters we can read the status of the different devices of the unit:
94H, 95H ∧Analogical outputs (% fan speed)
96H, 97H ∧Digital inputs (pressostats, protections, remote on/ off, remote cooling/ heating)
98H, 99H ∧Digital outputs (compressor, water pump, 4 way valve, antifreeze heater, alarm relay)
Correspondence with the different devices is the following:
94H and 95H parameters show the speed (in %) of fans 1 and 2 :
0: fan stopped
100: maximum fan speed
Intermediate values: fan in regulation
This value is valid for:
- EAR 0472 to 0812 standard and FP1.
- EAR 1003 to 1303 but only taking 0 and 100 values.

detailed meaning of each alarm
Example : if appear one alarm by high pressure , the parameters 9AH and 9EH will take value 2 2 (0000 0010 in binary),
when the cause of the alarm is settled ( pressostat restarted) , parameter 9AH will show the value 0 (0000 0000 in binary) but
in the parameter 9EH nothing will change until we do not reset the alarm in the controller ( pressing the reset button) .
