RBC-PCM02E
|
The accessory is designed to
fit into the SMMS or SHRM outdoor unit; it is a PCB that can
be used to perform several different functions. The PCB
accepts an input that would be volt free from an external
source to enable the required function. |
|
|
Application
For each of the applications listed below the PCB
is mounted in the outdoor electrical box and plugs into
different connectors to give the following functions: |
|
External Master On/Off
The PCB plugs into CN512 when a contact is made
between common and cool all of the units connected to that
system will start in their previous mode of operation.
When the contact is made between
common and heat the connected units will stop.
An example time switch would be a
Sangamo Suntracker ref 0456 these are available from RS or most
Electrical Wholesalers

Operation Mode Selection
Control
The PCB plugs into CN510 when no inputs are
present to the PCB the indoor units can independently control
their mode. If a contact is made between common and cool the
indoor units will be locked in cooling a mode locked will be
displayed on any remote controller. If the contact is made
between common and Heat the indoor units are locked in that
mode.
|
|
Night
Operation (Sound Reduction) Control
The PCB plugs into CN508 when a
contact is made between common and cool the night operation is
activated. This limits the compressor and outdoor fan speed. The
noise level will be reduced to 50dBA at 1M (free field).
|
|
Snow Fan
Control
The PCB plugs into CN509 when a
contact is made between common and cool the out door fan is
enabled to remove any snow from the condenser.
|
|
Connection
The PCB is connected to the
outdoor interface PCB where indicated to achieve the required
function. The PCB is then connected to a switch or relay contact
to activate the PCB as required.
|
|
Limitations
The maximum distance the contacts can be from the
PCB mounted in the outdoor unit is 500M is a 2 or 3 core 0.75mm
screened cable is used.
