Sequence Of Operation; Scheduling - Carrier WSHP Open v3 Integration Manual

Sequence of Operation

The multi-protocol WSHP Open controls mechanical cooling, heating, and waterside economizer outputs, based on
its own space temperature input and setpoints. An optional CO
the space maximizes the occupant's comfort. The WSHP Open has its own hardware clock that is automatically set
when you download the heat pump software to the board.
See Scheduling (page 23) for occupancy types.
The following sections describe the multi-protocol controller's functions. All point objects mentioned in this
sequence of operation reference the touchscreen interface. Points in Field Assistant and the i-Vu® application are
the same or similar.

Scheduling

Scheduling - You must configure time periods to schedule the transitions from occupied to unoccupied operation.
The time periods control the space temperature to occupied heating and cooling setpoints. The WSHP Open
operates continuously in the Occupied mode until you configure either a time schedule or a third party control
system Enables/Disables the BAS On/Off point. You must set your local time and date for these functions to
operate properly.
You can change the occupancy source to one of the following:
Occupancy Schedules - The controller is occupied 24/7 until you configure a time schedule using either the
Equipment Touch, Field Assistant, the i-Vu® application, or a third party Enables/Disables the BAS On/Off point.
You can disable this by going to Configuration > Unit Configuration > Occupancy Schedules, changing the point
from Enable to Disable and clicking OK.
NOTE You must Enable this point in order for the Equipment Touch, Field Assistant, or the i-Vu® application to
assign a time schedule to the controller.
Schedule_Schedule - The unit operates according to the schedule configured and stored in the unit. The schedule
is accessible via the Equipment Touch, the i-Vu® application, or Field Assistant. The daily schedule consists of a
start and stop time (standard or 24-hour mode) and 7 days of the week, starting with Monday and ending on
Sunday.
CAUTION Scheduling can only be controlled from one source.
Occupancy Input Contact (Option) - If configured for remote occupancy control (default), the WSHP Open can use
an external dry contact closure to determine the occupancy status of the unit. You must disable the Occupancy
Schedules in order to use the occupancy contact input. The unit enters an occupied mode when it senses the
abnormal input. After the input returns to its normal state, the unit stays in the occupied mode for the configured
Occ Override Delay period (15 minutes default).
BAS (Building Automation System) On/Off - For use with a Building Automation System that supports network
scheduling, you must disable the Occupancy Schedules so the BAS system can control the unit through a network
communication and the BAS scheduling function.
Global Occupancy Scheduling - The WSHP Open can read the occupancy status from another unit so that a group
of WSHP's can be controlled from a single occupancy schedule. The local Occupancy Schedules must be disabled
in order to use the global occupancy input.
BACnet Network Occupancy Input - The WSHP Open can accept an external BACnet Binary Network Input for
occupancy control. This function is only compatible with units used in BACnet systems. You need to configure the
System Occupancy BACnet network input point to locate the device and point name where the external occupancy
point information resides. You must also disable Occupancy Schedules in order to use this input.
