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
is displayed, 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 timer clock
input. The scheduling is set per the digital input
when this option is selected.
−
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 T600HCN-1 (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. You can also use this parameter
to sequence the startup of multiple units in one
location.
Note:
When adjusting the time with the UP/DOWN
arrow keys, holding the keys down changes the time
by 10-second intervals.
