Low Energy Consumption Fan Motor - Carrier 42 GW Installationsanweisung

HDB Control
Power supply connection
• Make earth connection prior to any other electrical connections.
• Disconnect the power supply to all circuits prior to handling any
electrical components.
• Before proceeding with the unit connection to the mains supply locate
live L and neutral N, then make connections as shown in the figure 40
(ref. 25, 20).
• The unit can be equipped with a "CRC" wire control or an I.R. control
which are supplied as accessories. If the "CRC" control is used
connected to the terminal block ref. 33 fig. 40, disconnect the I.R.
receiver cable of connector J5 (remote) ref. D.
• Connect the "CRC" cable ref. "E" in the box to connector J5 (remote) ref.
"D".
Window (1WS) and presence (1ECO) control
The window and presence contacts must be connected to the terminal
block ref. 33 fig. 40 according to the diagram.

Low Energy Consumption Fan Motor

Low Energy Consumption Fan Motor version
42GW...units can ensure a 0% - 100% constant air flow modulation (and
therefore the thermal and refrigerating capacity) thanks to the Inverter
technology combined with the last generation of high energy-efficient
electric motors (EC brushless). This enables a constant control on the
power supplied according to the room that need to be conditioned.
The result is 50% electric energy saving compared to traditional
3-speed asynchronous motors and a considerable reduction of acoustic
emissions.
The table below shows the electrical characteristics of the four types of
motors.

Valve connection
The valves must be connected to the terminal block ref. 33 fig. 40
according to the diagram.
Grouping connection (fig. 40a)
The communication card must be inserted into the special connector
"communication J8" provided on the card.
For more information refer to the manual provided with the grouping
kit.
Grouping configuration of several units (fig. 40b)
Connect the units in daisy chain configuration (white and blue cables in
parallel) for grouping. Refer to the figure below.
Fault codes:
In the case of failure and with the unit ON, the red LED on the board
starts flashing according to the fault code: 0.5 seconds ON and 0.5
seconds OFF followed by 5 seconds OFF.
The fault code table is shown below:
NOTE:
• The values showed on table are reported only at the Low Energy
Consumption Fan Motor to they are necessary add the control
input power which correspond about 5W, 9W for the pump and
3W or 6W for the valves (4 pipes).
The fan coil units of the series 42GW are submitted by Carrier to the NTC
control (see attached additional manual) for best regulation of room
temperature.
No further electrical connections are necessary (beside power supply
and communication bus) for this unit.(fIg. 39)
All connections between electric components and motor are factory
made.
