T60xDFH-4 and T60xDFH-4+PIR Series Thermostat Controllers with Dehumidification and Occupancy
Sensing Capability Installation Instructions

BI2 Configuration of Binary Input 2.
Default: None
(None): No function is associated with an input.
(Door Dry): Door contact only has an effect if BI1 is set to
MotionNO or MotionNC or if a PIR accessory cover is used. (See
the BI1 parameter earlier in this table.) The occupancy is now
dictated via BI1, BI2, or PIR. Any motion detected sets the zone to
Occupied status. The thermostat controller remains in the Occupied
mode until the door contact switch opens momentarily, at which
point the thermostat controller goes into Stand-By mode. If more
movements are detected, the Occupied mode resumes. While the
door is open, any movements detected by the PIR sensor are
ignored. Use a Normally Closed (N.C.) switching device. (Contact
open = door open; contact closed = door closed.)
(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.
(Filter): A Filter alarm is displayed. This alarm can be connected to
a differential pressure switch that monitors a filter.
(Service): A Service alarm is displayed on the thermostat controller
when the input is energized. This input can be tied into the air
conditioning unit control card, which provides an alarm should there
be a malfunction.
UI3 Configuration of Universal Input 3.
Default: None
(None): No function is associated with an input.
(COC/NH): Changeover Contact/Normally Heat: A dry contact input
is used to signal seasonal hot/cold water changeover. The contact
closes when cold water is present. Valid only for two-pipe systems.
(COC/NC): Changeover Contact/Normally Cool: A dry contact input
is used to signal seasonal hot/cold water changeover. The contact
closes when hot water is present. Valid only for two-pipe systems.
(COS): Changeover Analog Sensor: Used for hot/cold water
changeover switching. Valid only for two-pipe systems. (Parameter
Pipe No is set to 2.0.) If the water temperature is greater than 75°F/
24°C, hot water is present. If the water temperature is less than
75°F/24°C, cold water is present.
Note: Choose the selection option (0): Cooling Only for the
SeqOpera parameter to allow changeover to occur between
Cooling Only and Heating Only. The changeover sensor does not
operate in Cooling and Reheat, Heating and Reheat, or Cool/
Heat Four-Pipe and Reheat applications.
(SS): Supply Air Sensor Monitoring
MenuScro Gives the option of having the
display continuously scroll the
parameters.
Default: on
(off): The scroll is inactive.
(on): The scroll is active.
AutoMode Enables the auto function to be
visible within the MODE key menu.
(The
MODE key is the key at the far
left of the thermostat controller
cover.)
Default: off
(on): The auto function is active (Off-Auto-Heat-Cool). Provides
automatic changeover between heating and cooling.
(off): The auto function is inactive (Off-Heat-Cool).
%RH disp Displays the current humidity
reading (T603 and T605 models).
Default: off
(on): Displays the current humidity reading in % RH.
(off): Does not display the current humidity reading.
