4.1.1 CF modules: technical data
Power supply voltage: 230V~. type of current on charge:
• CF-05: 500 W maximum.
•
CF-15: 1500 W maximum.
• CF-22: 2200 W maximum.
Maximum absorption current:
•
CF-05: 2,5 A maximum current at 230 V~.
• CF-15: 8 A maximum current at 230 V~.
•
CF-22: 12 A maximum current at 230 V~.
Values and fuse type:
• CF-05: 5x20 2,5 A delayed.
•
CF-15: 5x20 8 A delayed.
• CF-22: 5x20 12 A delayed. the fuse considered is related to the maximum charge hypothesis (it is the fuse supplied). It is designed to protect the fan module power component. In no case a fuse of a superior capacity must be assembled. However, the fuse value has to be dimensioned on the charge to be piloted through the fan module (the resulting value must be lower than the maximum value). If dimensioned appropriately it also protects the charge.
•
Supplied power: varying according to the model (500W/1500W/2200W).
• Control signal type: pulse modulation.
•
Protection coefficient: IP00 (open board).
connection is performed by using Fast-on connectors assembled on boards.

PIN configuration
The module has a 4-way dipswitch to configure the RS232 signal.
Of the 4 ways available, the 3rd and the 4 th only are active. They perform the following tasks:
DIP 3 Enabling/disabling the ECHO signal.
This DIP allows to determine echo presence or absence. Sometimes the transmitter requires echo in order to verify the transmission.
If echo is not required, it can be excluded from the mains through the dip configuration; in this way the transmitter will not understand the signal in a wrong way and the communication is not invalidated.
DIP 4 Configures DTR polarity.
When you transmit in RS-485 the transmitter uses the DTR in order to make the line “busy”. Polarity is not fixed in a standard way, thus it must be made configurable.
Configuration is performed by setting jumpers as shown in the following figure:

Please remember the following observations
• The connection among the system’s modules and instruments for the RS 485 serial line must be made using a cable with 0,5 mm
2
conductors.
• The distance between the
with the P.C. and the last module must not exceed 1.000 m.
• Maximum instrument number: 32.
• For cable laying, follow the laws in force. The use of a shielded cable (such as Belden cable model 8762 with PVC shelth PVC, 2 conductors plus braiding, 20 AWG, rated capacity between conductors 89 pF, rated capacity between one conductor and other conductors connected to the electric shielding 161 pF).
• ALWAYS insert a 100 Ω , 0,25W resistance between the “+” and “–” terminals of the last mains instrument.
4.2.4 Multi-network interface: mechanical assembly
Instruments are designed to be wall-mounted or for mounting on DIN omega guide. The environment temperature allowed for a proper operation ranges from 0 and 50 °C. Do not mount the instrument in humid and/or dirty places.
4.2.5 Multi-network interface: standards
The product complies with the following standards:
•
LOW VOLTAGE: EN60335-1 if applicable
• EMISSION : EN50081-1 (EN55022)

The ECH 200 series can control air-air, air-water, water-water, condensing units, single-circuit units with 1 or 2 compressors.
The ECH 200 series features temperature control based on inlet or outlet probe, condensation control, automatic change-over, boiler or supplementary electrical heater control, internal fan control, and more.
The ECH 200 series can be programmed through the keyboard or a personal computer.
The ECH 200 series includes a copy card which can be used to upload or download parameter maps.
There are two types of keyboards available: TS/W wall-mounted remote keyboard and TS/WS wall-mounted remote keyboard with a sensor aboard.
Which sensors are compatible with the ECH 200 controller?
The ECH 200 controller primarily uses NTC temperature sensors (specifically NTC 103AT or NTC 6X40 models) and 4...20 mA signals. Input AI3 can be configured to process either an NTC sensor or a 4...20 mA signal.
