Configuring the Digital Inputs (DI1 and DI2)
Press the configuration menu access key. The first
prompt is to program Digital Inputs DI1 and DI2.
The digital inputs display an alarm condition when the
input is closed. An alarm message is included on the
scrolling Status Display Menu, and when the message
displays, the backlight momentarily lights up.
Each digital input can be programmed in one of five
conditions:
•
None
– No function is associated with the input.
•
Service
– A Service alarm is displayed.
•
Filter
– A Filter alarm is displayed.
•
RemNSB
– Remote Night Setback (NSB) timer
clock input. The scheduling is set per the digital
input when this option is selected. The time
continues to be displayed, but the menu related to
scheduling is disabled and no longer accessible.
−
Open Contact = Occupied setpoints
−
Closed Contacts = Unoccupied setpoints
•
RemOVR
– Remote override contact. This
disables all override menu functions of the
thermostat. The override function is controlled
manually by a remote, momentarily closed
contact. When configured in this mode, the input
operates in a toggle mode. With this function
enabled, it is now possible to toggle between
unoccupied and occupied setpoints for the amount
of time set by the temporary occupancy time
parameter.
When override is enabled through the digital
inputs, an
Override
message appears in the
Status Display Menu.

Setting the Power-up Delay (Pwr del)
On initial power-up of the T600HPP-2 (or each time
power is removed and reapplied), there is a delay
before any operation is authorized (fan, cooling, and
heating). The delay time is adjustable between 10 and
120 seconds. This parameter can also be used to
sequence the start-up of multiple units in one location.
Note:
When adjusting the time with the UP/DOWN

10-second intervals.

setup prompt appears in the display. Press YES to
enter the power delay setup menu.
