CH173D - Thermostat Fantini Cosmi - Free user manual and instructions

USER MANUAL CH173D Fantini Cosmi

CH173D is a radio receiver (actuator) that coupled to a transmitter of the Fan- tini Cosmi product line enables to remotely control a preset user (usually a boiler). Sent radio signal is free from interference with other device even if the same frequency is used.

INSTALLATION AND CONNECTIONS

Installation shall be performed according to current CEI Standards. The distance between actuator and transmitter must not exceed 30 m in closed spaces and 70 m in open spaces (N.B. Range data could vary according to environmental conditions). Do not shield the device with metallic parts. Connect cables to the base terminal board according to the wiring diagrams shown. Receiver power supply (230 V a.c.) shall be connected to terminals N and L whereas the user (pump, burner, zone valve, humidistat, etc.) shall be connected to terminals 1 and 2. N.B. Several receivers can be connected to one transmitter. OPERATION The receiving device features three leds giving the following indications: POWER ON: when this led is on it indicates that the receiver is properly powered. The meaning of the different colours of this led is specifi ed below. AUTO: when this led is on it indicates that the receiver is confi gured in AUTO- MATIC MODE. When the led is off the MANUAL MODE is active. CONTACT STATUS: when this led is on it indicates that the relay contact is closed, otherwise (led off) it will be open. CH173D RADIO ACTUATOR FOR DIN RAIL MOUNTING6 Boiler 30 metres max. Receiver Transmitter N L 4 1 2 Each time the button is pressed the three operating modes are started in turns: AUTOMATIC (“AUTO” led: ON) In this operating mode, the receiver receives a radio signal coded by the chro- nothermostat via the transmitter interface and triggers the integral relay. The “POWER ON” led takes on a different colour according to the quality of the signal received:

• RED: signal absent or very disturbed

• ORANGE: satisfactory reception

• GREEN: good reception Fast and brief led fl ashing indicates the reception of radio data sent by the transmitter. 230V50Hz CONTACT STATUS AUTO POWER ON7 MANUAL ON (“AUTO” led OFF and “CONTACT STATUS” led ON) In this operating mode, the receiver relay contact is always closed and the radio transmission implemented by the transmitter module is ignored (conse- quently chronothermostat / thermostat commands are not accepted). MANUALE OFF (“AUTO” led OFF and “CONTACT STATUS” led OFF) In this operating mode, the receiver relay contact is always open and the radio transmission implemented by the transmitter module is ignored (consequently chronothermostat / thermostat commands are not accepted).

SYSTEM CODE SELF-LEARNING PROCEDURE

Before using the CH173D actuator in AUTOMATIC mode its code shall be me- morised into the Fantini Cosmi transmitter you purchased. To prevent storing of a different code, during the confi guration procedure the reception sensitivity is reduced and therefore the distance between transmitter and receiver shall be 2 m max. Proceed as follows:

1. Turn the receiver on and then keep the button pressed until selecting the

AUTOMATIC MODE (see paragraph “OPERATION”).

2. Keep the button pressed for over 10 seconds to start the “SELF-LEARNING”

procedure, the “AUTO” led will start fl ashing.

3. Force radio thermostat / chronothermostat transmission (refer to the relevant

4. Carry out the OPERATION CHECK procedure to check for correct confi gu-

ration of the programmed receiver. N.B.: Max. 45 seconds shall pass between step 2 and step 3 of the above procedure. Receiver “POWER ON” led will turn red if over two minutes pass without re- ceiving data. OPERATION CHECK To use the chronothermostat/ thermostat refer to the relevant instruction manuals. -Make sure the receiver is in AUTOMATIC mode (see paragraph OPERA- TION). -Wait for chronothermostat/ thermostat data transmission and then check whe- ther CH173D relay status matches with chronothermostat/ thermostat. - Switch over chronothermostat/ thermostat and check whether the CH173D relay status changes. Should the “POWER ON” led be red then transmitter and receiver are too di- stant: communication between the two devices is null or unreliable.8 During normal operation certain radio signals could be lost due to external disturbances, these interferences however do not impair device operation if they last for a short time.
