Unit Start-Up Heating Mode

NOTE: Operate the unit in heating cycle after checking the cooling cycle. Allow 5 minutes between tests for the pressure or reversing valve to equalize.

1.Turn thermostat to lowest setting and set thermostat switch to HEAT position.

2.Slowly turn the thermostat to a higher temperature until the compressor activates.

3.Check for warm air delivery at the unit grille within a few minutes after the unit has begun to operate.

4.Check the temperature of both supply and discharge wa- ter. Compare to Tables 15-25. If temperature is within range, proceed. If temperature is outside the range, check the heating refrigerant pressures in Tables 15-25.

5.Once the unit has begun to run, check for warm air deliv- ery at the unit grille.

6.Check air temperature rise across the coil when compres- sor is operating. Air temperature rise should be between 20 and 30 F after 15 minutes at load.

7.Check for vibration, noise and water leaks.

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. 29.

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.
