Resumen del manual
For the new jumper setting to take effect - all 24V power to the board must be removed and reapplied. 6. Complete the installation and power up the unit, re-applying both 240V & 24V. FIGURE 1: Outdoor Unit Control Box DEFROST CURVE SELECTION When the control board is replaced, the jumper MUST be placed in a numbered position. Select the proper jumper position from Table1. If the jumper is missing or in the P position, the replacement control will not energize the compressor. When the jumper position is changed, the control will not act upon the jumper changes until the thermostat calls are de-energized or power (24 VAC) to the control is cycled. TABLE 1: Defrost Initiate Curves FIGURE 2: Demand Defrost Control Module The control will display the active defrost curve using the X/L terminal when the heat pump is operating in a defrost cycle that has been forced using the TEST inputs. For instance, the X/L output will be energized with two flashes when defrost curve 2 is active. The control only reads the jumper input when the Y and W thermostat inputs are de-energized.
