Unit Start-Up with WSHP Open Controls —

The WSHP Open is a multi-protocol (default BACnet*) con- troller with extensive features, flexible options and powerful capabilities. The unit comes from the factory pre-programmed and needs minimal set up to function in a BAS (Building Automation System) system or provide additional capabilities to Carrier's WSHP product line. Most settings on the controller have factory defaults set for ease of installation. There are a few settings that must be configured in the field and several settings that can be adjusted if required by unique job condi- tions. Refer to Appendix A — WSHP Open Screen Configura- tion. In order to configure the unit, a BACview6 display is required. See Fig. 34.

NOTE: If the WSHP Open control has lost its programming, all display pixels will be displayed on the SPT sensor. See the WSHP Third Party Integration Guide.

When the unit is OFF, the SPT sensor will indicate OFF. When power is applied, the SPT sensor will indicate tempera- ture in the space at 78 F.

To start-up a unit with WSHP Open controls:

1.To plug in the BACview6 handheld display into a SPT sensor, point the two ears on the connector up and tilt the bottom of the plug toward you. Insert the plug up into the SPT sensor while pushing the bottom of the plug away from you.

2.BACview6 should respond with "Establishing Connec- tion." The Home screen will then appear on the display showing operating mode and space temperature. Press any button to continue.

See Appendix A — WSHP Open Screen Configuration for the hierarchal structure of the WSHP Open controller. All functions of the controller can be set from the Home screen.

3.When the Login is requested, type 1111 and push the OK softkey. The Logout will then be displayed to indicate the password was accepted.

4.To set the Clock if it is not already displayed:

a.Select System Settings from the Home screen, then press Clockset.

b.Scroll to hour, minute and second using the arrow keys. Use the number keypad to set actual time.

c.Scroll to day, month and year using arrow keys. Use number keypad to set date.

5.To set Daylight Savings Time (DST):

a.Push the DST softkey. The display will indicate 02:00:060 which is equal to 2:00AM.

b.To program the beginning and end dates, scroll down to the beginning month and press the enter key. The softkeys (INCR and DECR) will activate to increment the month in either direction, Jan, Feb, March, etc.

c.Use number keys to select the day of month and year.

d.Push the OK softkey to finalize the data.

6.To view configuration settings:

a.Select the Config softkey.

b.Select the Service Config softkey. Scroll through the factory settings by using the up and down arrow keys. See below for factory settings.

Only the following settings will need to be checked.

# of Fan Speeds — This should be set to "1" for units with PSC motors and set to "3" for units with ECM motors.

Compressor Stages — This should be set to "1."

Factory Dehumidification Reheat Coil — This should be set to "none" unless the modulating hot water reheat option is supplied in the unit, then set to "installed."

The condenser water limit needs to be verified depending on design parameters and application, whether geothermal or boiler/tower.
