Configuring the T600HPx-4 or T600HPx-4+PIR
Series Thermostat Controller
The T600HPx-4 and T600HPx-4+PIR Series

Configuring Inputs DI1 and DI2

When DI1 and DI2 are configured for an alarm
condition, an alarm condition is displayed locally when
the input is closed. An alarm message is included on
the scrolling Status Display Menu and when the
message is displayed, the backlight momentarily
lights up.
Each input can be configured to the Selection Options
included in Table 2.
Selection Options
Range: 0 to 1,000
(None): No function is associated with an input.
(Service): A Service alarm is displayed on the thermostat controller
when the input is energized. Tie this input into the air conditioning
unit control card, which provides an alarm if a malfunction occurs.
(Filter): A Filter alarm is displayed. This alarm can be connected to
a differential pressure switch that monitors a filter.
(RemOVR): Temporary occupancy request via a remote input. This
override function is controlled by a manual remote occupancy
override. When enabled, this condition disables the override
capability of the thermostat controller.
(RemNSB): Remote Night Setback (NSB) via a time clock input, an
occupancy sensor, or from a voltage-free contact.
Contact open = Occupied; contact closed = Unoccupied.
(Fan lock): A backlit flashing Fan lock alarm is displayed on the
thermostat controller when the input is not energized. This alarm is
used in conjunction with a local airflow sensor connected to the
input. The thermostat controller heating or cooling action is locked
out if no airflow is detected 10 seconds after the fan (Terminal G) is
energized. Contact open = no airflow; contact closed = airflow
present.
