Johnson Controls DRCR, Owner'S Manual

Take the following precautions to reduce the risk 

of property damage



Do not touch the main circuit board or electronic components in the

controller or remote devices. Also, make sure that dust and/or steam

does not accumulate on the circuit board.



Locate the wireless zone controller at a distance of at least 3 ft.

(approx. 1m) between the indoor unit and electric lighting. Otherwise,

the receiver part of the unit may have difficulty receiving operation

commands.



If the wired zone controller is installed in a location where

electromagnetic radiation is generated, make sure that the wired zone

controller is shielded and cables are sleeved inside conduit tubing.



If there is a source of electrical interference near the power source,

install noise suppression equipment (filter).



During the run test, check the unit’s operation temperature. If the unit is

used in an environment where the temperature exceeds the operation

boundary, it may cause severe damage.  Check the operational

temperature boundary in the manual. If there is no specified

temperature, use the unit within the operational temperature boundary

of 35°~104°F (0~40°C).



Read installation and appropriate user manuals for connection with PC

or peripheral devices. If a warning window appears on PC, the product

stops, does not work properly or works intermittently, immediately stop

using the equipment.

INSTALLATION PRECAUTIONS 

To reduce the risk of serious injury or death, the 

following installation precautions must be 

followed: 



If the remote sensors are not used with this controller then do not

install this controller…

-

in a room where there is no thermostat.

-

where the unit is exposed to direct sunshine.

-

where the unit will be in close proximity to a heat source.

-

where hot/cold air from the outdoors, or a draft from elsewhere

(such as air vents, diffusers or grilles) can affect air circulation.

-

in areas with poor air circulation and ventilation.



Perform the run test using the controller to ensure normal operation.

Safety guards, shields, barriers, covers, and protective devices must

be in place while the compressor/unit is operating. During the run test,

keep fingers and clothing away from any moving parts.
