Application
2281, 2283, The amount of time (in hours) that the controller will operate in
2284, 2286, day mode, when the override switch is pressed, while the
2287 controller is in night mode.
2281, 2283, Indicates the mode that the controller is operating in with
2284, 2286, respect to the override switch. NIGHT indicates that the switch
2287 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
(Point 29) indicates night mode.
2281, 2283, AUX indicates that auxiliary radiation is available. NOAUX
2284, 2286 indicates that auxiliary radiation is not available.
Valid input: AUX or NOAUX
2281, 2283, Point commanded by the field panel PPCL to enable or disable
2284, 2286, mixed air damper modulation (free cooling).
2287
2281, 2283, Actual status of a contact connected to the controller at DI 2.
2284, 2286, ON indicates that the contact is closed; OFF indicates that the
2287, 2299 contact is open. If a wall switch is used, it is connected to DI 2.
Refer to WALL SWITCH (Point 18).
2281, 2283, Actual status of a contact connected to the controller at Al 3/Dl
2284, 2286, 3. ON indicates that the contact is closed; OFF indicates that
2287, 2299 the contact is open. When a contact is connected at DI 3, Al 3 is
not available. Refer to AUX TEMP (Point15).
2299 Actual status of a contact connected to the controller. ON
indicates that the contact is closed; OFF indicates that the
contact is open.
2281, 2283, Actual status of the low temperature alarm, which is determined,
2284, 2286, by the current status of the low temperature detection thermostat.
2287 ON indicates that a low temperature has been detected. OFF
indicates a normal condition.
2287 YES indicates a DX coil is used in cooling mode. NO indicates a
chilled water valve is used in cooling mode.
Valid input: YES or NO
2281, 2283, Indicates whether electric heating is being used.
2284, 2286 Valid input: ELEC or NOELEC
2281, 2283, ENABLE allows two-position valves to close when the face-
2284, 2286 bypass damper has been closed (to full-bypass) for 2 minutes.
DISABL disables the feature.
Valid input: ENABLE or DISABL
2281, 2283, Indicates the mode in which the controller is operating. Day
2284, 2286, temperature setpoints will be used in day mode. Night
2287, 2299 temperature setpoints will be used in night mode. This point is
normally set by the field panel.
2281, 2283, This point indicates whether or not the unit is currently in warm-
2284, 2286, up/cool-down. ON indicates the unit is in warm-up/cool down.
2287 OFF indicates the unit is not in warm-up/cool-down.
