Description Address Application Description
Dl OVRD SW {19} 2583, 2584, 2590 Actual indication of the status of the override switch (not
physically available on all temperature sensor models) at the
room temperature sensor. ON indicates that the switch is
being pressed. OFF indicates that the switch is released.
Valid input: ON or OFF
OVRD TIME 20 2583, 2584 Amount of time in hours that the controller will operate in
day/occupied mode when the override switch is pressed
while the controller is in night/ unoccupied mode.
NGT OVRD {21} 2583, 2584 Indicates the mode that the controller is operating in with
respect to the override switch. NIGHT indicates that the
switch has not been pressed and the override timer is not
active. DAY indicates that the switch has been pressed and
the override timer is active. The controller then uses a day
mode temperature setpoint. This point is only in effect when
DAY.NGT indicates night mode.
RMTMP OFFSET 22 All Compensates for deviations between the value of ROOM
TEMP and the actual room temperature. This corrected
value is displayed in CTL TEMP.
RMTMP OFFSET + ROOM TEMP = CTL TEMP
FREE CLG {23} 2583, 2584 Point commanded by the field panel PPCL to enable or
disable mixed air control (free cooling).
DI 2 {24} 2583, 2584, 2590 Actual status of a contact connected to the controller at Dl 2.
ON indicates that the contact is closed; OFF indicates that
the contact is open. If a wall switch is used, it is connected
to DI 2. See WALL SWITCH.
DI 5 {25} 2583, 2584, 2590 Actual status of a contact connected to the controller at
Al 5/Dl 5. ON indicates that the contact is closed; OFF
indicates that the contact is open. When a contact is
connected at Dl 5, Al 5 is not available. See Point number
15. The physical input can not be used for both analog and
digital input at the same time.
DI 6 {26} 2583, 2584, 2590 Actual status of a contact connected to the controller. ON
indicates that the contact is closed; OFF indicates that the
contact is open. Application 2583/2584: DI 6 can be used to
monitor an input that changes state when the heat pump is
in alarm. DI 6 can be unbundled to send alarm information
to the field panel for centralized alarm monitoring.
CMP2 MlN OFF 27 2583 Minimum time, in minutes, that compressor 2 will remain
OFF before turning ON.
HTG2 MlN OFF 27 2584 Minimum time, in minutes, that heating compressor 2 will
remain OFF before turning ON.
CMP2 MlN ON 28 2583 Minimum time, in minutes, that compressor 2 will remain ON
before turning OFF.
HTG2 MlN ON 28 2584 Minimum time, in minutes, that heating compressor 2 will
remain ON before turning OFF.
