A cable convertor control converts the rotary motion of a knob to a linear motion, to push or pull a control cable.
When installing a new convertor or control cable it is necessary to adjust the cable for proper operation of the controlled device. For a heater valve, it is best to adjust the cable to ensure the heater water control valve has 100% shut off, verified at the valve. Heater output will easily override air conditioner cooling capacity. Therefore, a valve that does not have 100% shut off will add heat to the system to some degree. To adjust the control, manually put the valve to 100% closed. Manually turn the converter to the 100% off position. Install the cable loosely in the clamps, making sure the valve remains 100% off. It is acceptable for the convertor to creep away from the full off position but the valve must remain 100% closed. Tighten the cable clamps on both ends of the cable.
