CoolAutomation CoolMasterNet User manual

Warning
Read these Safety Precautions carefully to ensure correct installation.
This manual classies precautions into WARNING and CAUTION.
WARNING
Only qualied personnel must carry out the installation work.
Ask your dealer or technical representative to install the unit.
Any deciency caused by your own installation may result in an electric shock or re.
All electrical work must be performed by a licensed technician, according to local
regulations and in accordance with the instructions in the installation manual.
Any lack of electric circuit or any deciency caused by installation may result in an electric
shock or re.
Do not relocate or reinstall the CoolMasterNet by yourself.
Any deciency caused by your own re-installation may result in an electric shock or re.
Make sure that all wiring is secured, that specied wires are used and that no external
forces act on terminal connections or wires. Improper wiring connections or installation
may produce heat and result in re.
Before touching electrical parts, turn o the unit.
To dispose of this product, consult your dealer.
Failure to follow WARNING is very likely to result in such grave consequences as
death or serious injury

Caution
CAUTION
Do not allow children to play with the CoolMasterNet and supervise them not to get access
to the appliance.
CoolMasterNet is not to be used by persons with reduced physical, sensory or mental
capabilities, or lack of experience and knowledge.
Do not disassemble, modify or repair the CoolMasterNet.
Any deciency caused by your modication or repair may result in an electric shock or re.
Never let the CoolMasterNet to get wet.
Water can cause damage to the CoolMasterNet, and may cause an electric shock or re.
Do not use ammable materials (e.g. hairspray or insecticide) near the CoolMasterNet.
Do not clean the CoolMasterNet with organic solvents such as paint thinner. The use of
organic solvents may cause cracking, damaging the CoolMasterNet, causing electrical
shock or re.
Do not apply AC110V or AC220V to the CoolMasterNet. The maximum voltage that can be
applied to the unit directly is 24V DC.
If damaged CoolMasterNet can generate heat and cause a re.
Failure to follow CAUTION may result in serious injury or property damage,
and in certain circumstances, may result in a grave consequence.

Caution
DO NOT INSTALL THE COOLMASTERNET IN THE FOLLOWING LOCATIONS:
a) Where a mineral oil mist or oil spray or vapor is produced, for example, in a kitchen.
Plastic parts may deteriorate and fall o or result in water leakage.
b) Where corrosive gas, such as sulfurous acid gas, is produced.
c) Near machinery emitting electromagnetic waves.
Electromagnetic waves may disturb the operation of the CoolMasterNet and cause the unit
to malfunction.
d) Where ammable gas may leak, where there is carbon ber or ignitable dust
suspensions in the air, or where volatile ammable such as thinner or gasoline are
handled.
Operating the CoolMasterNet in such conditions can cause a re.
e) High temperature area or directly amed point.
Heating and/or re can occur.
f) Moist area, where there is exposure to water.
If water enters the inside of the CoolMasterNet, it may cause electric shock and electrical
components may fail.
Failure to follow CAUTION may result in serious injury or property damage,
and in certain circumstances, may result in a grave consequence.

Non-VRV HVAC system conguration on L1
Changing the dip switches , while DC voltage is present on L1, may damage
the CoolMasterNet.
For Daikin/Mitsubishi Electric Non-VRV/VRF equipment, DC voltage supply by CoolMasterNet might be required
for proper operation.
Make sure CoolMasterNet is disconnected from power and HVAC line.
Measure DC voltage on HVAC communication line L1
If no DC voltage. Daikin 14-16V DC, Mitsubishi 28-30V DC, change the dip switches as shown below
Turn ON the power for CoolMasterNet and connect it to HVAC line.
