Overview
1.1
CoolMaster is a versatile seamless Control adapter connecting VRV / VRF Air Conditioning Systems
with any RS232 or USB featured devices like Home PCs, Embedded PCs or Home Automation
Controllers.
Connecting such Controllers through common RS232 or USB interfaces with the CoolMaster will
provide end-users with full control of all indoor units enabling them with access to HVAC's various
functionalities including diagnostic.
Home Automation Integrators and HVAC installers when utilizing CoolMaster will not have to worry
anymore about the complexity involved in understanding and working with HVAC's internal
Communication lines and gateways including their unique physical layers.
Now, with the CoolMaster integrators will be provided only with a simple, well documented open ASCII
protocol over RS232 or USB to seamlessly integrate with any Home Automation applications. . The
product is provided with LCD that continuously indicates the status of indoor units and malfunction
alerts. Basic connectivity of the product to the system can be viewed in the following schematic.
Compatibility
1.2
The CoolMaster range of products is compatible with several leading VRV/VRF air conditioning

In VRV/VRF air conditioning system, regardless of the specific AC manufacturer, CoolMaster should
be connected to the main air conditioning communication line. The specific details about connection to
the AC system are provided in Connection and Wiring paragraph.
Using the CoolMaster with non VRV/VRF systems will require additional interface adaptors for each
indoor unit.

Simple RS232 Interface for Easy Integration
CoolMaster is equipped with an RS232 serial port. The port can be used in two different ways:
1. Configuration and monitoring of the air conditioning system from PC using simple Windows
based terminal program. (See PC connection)
2. Connected to Home Automation controller or BMS.
See Commands List for brief description of supported commands. The complete documentation can
be found in the Programmers Reference Manual.
Air Conditioning System Monitoring
CoolMaster enables Home Automation controllers or BMS to receive the air conditioning system
status. The status is provided by CoolMaster as a response to "stat" command (The syntax and
operands of the command can be found in the Programmers Reference Manual). CoolMaster provides
the following information for each indoor unit of the AC system:
·Operation mode - This parameter indicates whether the required indoor unit is set for Cooling,
Heating, Fan, Dry or Auto operation.
·The feedback returns the operation mode regardless of operation status (whether the unit is "ON" or "Off').
·Within the same air conditioning system different indoor units can be in different operation modes.
·Set Point Temperature - This is the desired temperature defined by the user on a given indoor unit.
·Fan Speed - Currently set fan speed of the monitored indoor unit. There are 4 available Fan Speeds:
High, Medium, Low and Automatic.
·Sanyo and Toshiba support all 4 Fan Speeds.
·Most of the Daikin indoor units support only 2 Fan Speeds: High and Low.
·Some of the new Daikin units (FXDQ-P and FXMQ) support 3 Fan Speeds: High (HH), Medium (H) and Low
(L).
·Room Temperature - This is the temperature, measured in the return air inside the monitored indoor
unit.
·This temperature measurement shows only the temperature inside the indoor unit and it doesn't always
indicate correctly the temperature in the room.
·Swing status - This parameter indicates whether the swing operation is "on" or "off" in the monitored
indoor unit.
·This parameter is only available for wall mounted and cassette type indoor units.
·Filter Sign - Each indoor unit is designed to show a reminder regarding cleaning of the filters. After
certain number of operation hours the "filter" sign will be shown on the local remote controller. The
time period, after which the sign appears may differ between different types of indoor units.
·Malfunction code - When abnormal operation of the air conditioning system occurs, there will be an
indication, regarding the malfunction. The malfunction can be local. In this case the specific indoor
unit will halt and malfunction code will appear on the local thermostat. When the malfunction is
general, the entire air conditioning system will stop and the malfunction code will show in all local
thermostats.
·When running "stat" command for a certain indoor unit there could be more than one malfunction code.

Controlling the Air Conditioning System
·Operation mode - CoolMaster enables Home Automation controllers or BMS to set the operation
mode of each indoor unit independently. Cool, Heat, Fan, Dry and Auto operations are possible.
·For heat pump air conditioning system Coo" and Heat operation status cannot be set simultaneously for 2
different indoor units. For example, once at least one of the indoors has been set for Cool, all other indoor units
of the system cannot be set to Heat.
·In Daikin air conditioning systems one of the indoor units can be set as a master for Cool or Heat operation. In
this case, Cool or Heat operation of the entire air conditioning system may be carried only by sending the Cool
or Heat command to this specific indoor unit. Sending the Cool or Heat command to other indoor units will have
no effect.
·Operation status - CoolMaster enables Home Automation controllers or BMS to turn indoor units to:
ON and OFF.
·Set Point Temperature - The Set Point Temperature of each indoor unit can be changed separately
in two ways:
1. Defining the desired temperature.
2. Raising or lowering the existing set temperature by the defined delta.
·Fan Spped - CooMaster enables Home Automation controllers or BMS to change the fan speed of
the specified indoor unit.There are 4 available fan speeds: Low, Medium, High and Auto.
·Sanyo and Toshiba support all 4 Fan Speeds.
·Most of the Daikin indoor units support only 2 Fan Speeds: High and Low.
·Some of the new Daikin units (FXDQ-P and FXMQ) support 3 Fan Speeds: High (HH), Medium (H) and Low
(L).
·Reset Filter Sign - Each indoor unit is designed to show a reminder regarding cleaning of the filters.
After certain number of operation hours the "filter" sign will show on the local remote controller. The
time period, after which the sign appears may differ between different types of indoor units.
CoolMaster enables Home Automation Controllers or BMS to send a command to the system that
will reset the filter sign.
·Swing (On/Off) - CoolMaster enables Home Automation Controllers or BMS to change the status of
the "Swing" function on each indoor unit from "On" to "Off" and vise versa. Swing function is
available on wall mounted and cassette type
Plug&Play Device
When CoolMaster is connected to the air conditioning system, it does not require any additional
configuration. After connecting the wiring, supplying the power and defining addresses of the indoor
units (as explained in the installation chapter) the system is ready to work.
Field Upgradeable Firmware
When new features are added or some changes have been applied to the CoolMaster's functionality,
the firmware of the already installed CoolMaster can be easily upgraded by the user himself. The latest
firmware can always be downloaded from http://www.coolaut.com/secdown/ using the following user
name and password:
User : cooluser
Password : coolpasswd
The upgrade process is described in details in the Programmers Reference Manual.
Customizable for Specific Applications
CoolMaster has a number of optional functions, that can be ordered by request in order to fit specific
customer's needs. Example of optional features:
1. Digital/Analog I/O.
2. Connection to the additional devices, such as CoolEx, CoolBridge etc'.

The CoolMaster should be placed in a dry ventilated place. It is advised to be installed in the electricity
cabinet near the BMS/Home Automation controller since the length of the RS232 connecting cable is
limited (see Technical specifications). In this case it is advised to use the optional DIN Rail Fixing, as
shown in the following diagrams.
Another option is mounting the CoolMaster directly on wall with Wall Mounting Plate (Accessories).
