Override/Reset Button (Timed
Override & Alarm Reset):
When the "Override/Reset" Button is pressed, the thermis-
tor sensor is shorted. If held for more than 3 seconds but less
than 11 seconds, it puts the controller into a timed Occupied
Override (the time is set by the controller). If the unit is in
alarm, then holding the "Override/Reset" Button for more than
11 seconds will clear all alarms in the controller but only if the
cause of the alarm has already returned to its non-alarm condi-
tion. Some alarms will not reset from the digital room sensor.
In this case, power to the unit must be cycled off for 5 sec-
onds to clear the alarm. Continuously resetting alarms from
the room sensor could damage the controller. Please call a
service technician when repeated alarm resets are required to
keep the unit operational.
Occupied Button (Occupied/
Unoccupied Request):
Note: Terminal "U" opens HI to source power on power-up
"Occcupied"
When the "Occupancy" Button is pushed, the current "Oc-
cupied" or "Unoccupied" status of the sensor will be toggled
to the opposite condition for 20 seconds. Both the display and
"U" terminal output reflect the new status during the 20
seconds. If a confirmation signal is received from the control-
ler into the Status Input terminal "1" within 20 seconds, then
the new occupancy condition remains; otherwise the "U" ter-
minal will return to the original state and the "Occupied" Icon
will flash the desired occupancy state every 8 seconds.
