FAN INTERFACE LEAD
RBC-SMFI
|
The fan interface module will
allow an external ventilation fan to be controlled from an
indoor unit. The device consists of a single pole relay
housed in a small electrical enclosure, which connects to a
Digital Inverter or VRF indoor unit via the supplied
connection lead.
|
|
|
Application
The module is intended to facilitate the
installation and control of an external ventilation fan, which
may be used to supply fresh air or to move conditioned air to
another location. The external fan is enabled with the indoor
unit, however this can be over-ridden using the external fan
control button on the RBC-AMT21/31E remote controllers. |
|
Connections
The interface should be mounted adjacent to the
indoor unit and secured with the self-adhesive fasteners
supplied. Only when the device has been adequately secured
should the CN32 connection be made to the indoor unit PCB. The
Live Supply of the external fan should then be connected via the
relay contacts located in the fan interface enclosure. On
completion of the installation works, the remote controller will
require configuring to allow the operation of the auxiliary
ventilation button.

+ CL and CHECK buttons Simultaneously for 3 seconds.
2) Using the temperature set
buttons select menu item number 31.
3) Change the value in menu item
31 from 0000 to 0001 using the timer buttons.
4) Press the SET button to
confirm the change.
5) Press the CHECK button to return to normal

Limitations
The relay contacts are rated at 230 Volts, 6Amps
resistive or 1.5Amps inductive load.
Loads in excess of this will
require the installation of an additional power relay.
It is the responsibility of the
installing contractor to ensure that a means of safe isolation
is provided and that all electrical wiring conforms to the
current edition of BS7671.
