1.3 About the BMS module
Version: 4.0 (10-11-2011)
1.3.1 Applications
The BMS module has been designed to control the comfort air
curtain, model CA and CA
system. It is being used instead of a control panel.
The module is designed as a remote control to set all user
functions and some control functions of the unit without user
intervention. The module can also be used to read the status
of some important unit parameters.
The BMS module is connected to the unit via a Biddle control
cable. Via one or more low-voltage cables using plug connec-
tions, the building management system is linked to the printed
circuit board in the BMS module.
1.3.2 Operation
The BMS module has several input and output ports to
operate two main functions:
1. The building management system can adjust the unit func-
tion to a changing indoor or outdoor climate by making or
breaking a contact on the input ports.
2. By breaking a contact on an output port, the BMS module
can inform the building management system about the
operation of the unit.
The functions of the input and output ports are further
explained in paragraph 2.3.
Besides that, it is possible to use and program the input and
output ports on the unit, as is described in section 3.4.
Using the control panel at the front of the BMS module, a
number of features of the BMS module and of the air curtain
can be set. These settings concern:
- adjusting the preferences for use and maintenance of
the unit,
- tuning the unit operation to the installation.
The settings are explained in chapter 3 'Settings' .
It is not possible to operate the air curtain via the control
panel as described in chapter Operation of the unit's manual.
Only the key will function as described.
