Room Controller Troubleshooting

Lights turn ON
but remain at a
dimmed level
(lighting does not
respond to dimming
raise controls)
Slider Station
●
If a slider station is installed, other raise lower controls will be disabled. Verify that the slider operates
as intended.
0-10V
Output
●
Disconnect 0-10V terminal blocks from the Room Controller. Lighting should go full bright:
●
If lighting does not go full bright, check all wiring and ballasts/drivers for miswires and shorts on the
0-10V wiring until the problem is found.
●
Verify with a meter that at least 10 VDC is present between the purple and gray disconnected leads.
The Room Controller is a sink device (requires the ballast/driver provide the dimming voltage).
●
If lighting does go full bright when disconnected from the Room Controller, check for polarity reversal
on the 0-10V leads.
●
Reconnect 0-10V wiring to the Room Controller. Press the reset button on the Room Controller to verify
that lighting turns ON and goes full bright for 3 seconds:
●
If it does go to full bright before resuming the dimmed level refer to the Demand Response and
Daylighting possible causes.
●
If lighting does not go full bright during the 3 second reset period, check that the maximum trim level
potentiometer is not set too low for the space.
Demand
Response
●
Demand Response Mode may have caused light levels to automatically reduce. Check contact from
demand response system. Verify that the demand response Energy Options DIP Switches are set for the
appropriate lighting level.
Daylighting
●
Daylight levels may not be correct for your space. Press the reset button on the controller to verify loads
turn ON to Full ON for 3 seconds. If loads go Full ON then resume dimmed level:
●
Look in the Daylight Sensor lens to determine if the Green LED is ON fairly steadily. If it is, the sensor
is seeing more daylight than its range will allow. Set a new range using the HHPRG-RC remote and
the Advanced Daylight Level Adjustment procedures in the installation instructions.
●
If the Daylight Sensor’s green LED is not on, use the HHPRG-RC remote to adjust daylight levels per
the Advanced Daylight Level Adjustment procedures in the installation instructions.
●
Check the High End trim pot to ensure it is not set all the way counter-clockwise.
Lights turn ON but
remain at a full
bright level
(lighting does not
respond to dimming
lower controls)
Slider Station
●
If a slider station is installed, other raise lower controls will be disabled. Verify that the slider operates
as intended.
0-10V
Output
●
Disconnect 0-10V terminal blocks from the Room Controller. Lighting should remain full bright:
●
Temporarily remove the 0-10V wiring for a zone and then connect the purple and gray wires together.
Verify that the load goes full dim. If the load does not go full dim, check all wiring and ballasts/drivers
for miswires and shorts until the problem is found.
●
Verify with a meter that at least 10 VDC is present between the purple and gray disconnected leads.
The Room Controller is a sink device (requires the ballast/driver provide the dimming voltage).
●
If lighting does go full dim when disconnected from the Room Controller, check for polarity reversal on
the 0-10V leads.
●
Reconnect 0-10V wiring to the Room Controller and continue with the additional troubleshooting steps
listed below.
Alert Mode
●
If Alert Mode has been activated, lighting will be ON and full bright until the alert is cleared. Disconnect
contact into the Alert Mode terminal to verify normal operation resumes. Troubleshoot the connected
system to determine the cause of the alert signal.
