Given that the air conditioning unit is installed on the
roof of a building or property, users must under no
circumstances inspect or adjust the unit themselves.
All of inspections or adjustments that may be made
by the user are performed using the DPC-1
thermostat.
Should the air conditioning unit become faulty, the
auto-diagnostics system in the unit will identify the
source of the fault and will activate the indicator -1- on
the DPC-1 thermostat screen. The bottom left of the
screen will also display a two-digit figure -2- to indicate
the part affected. See
Placing the unit out of service
due to breakdown
, see on page 11.
Where the thermostat screen continues to display the
indicator -1- and any fault code or if the air conditioner
does not start, contact a Johnson Controls Inc.
Authorised Technical Assistance Service.
