Hayward Pro Logic Model: PL-P-4 Installation - Page 17

Temperature Sensors The Pro Logic utilizes 10K ohm thermistor type sensors. Three sensors (water temperature, air temperature and solar temperature) are included. If the Pro Logic is being used to control a solar heating system, the solar sensor is required. The sensors are provided with a 15 ft. cable. See page 5 and the diagram below for installation information. POOL/SPA SENSOR AIR SENSOR SOLAR/SPA SENSOR Remote Display/Keypad The Pro Logic main unit can connect to a maximum of 3 remote wired display/keypads (ordered separately). Use four conductor cable (typically phone cable) to connect the wired remote display/keypad with the Pro Logic Control Center as shown below. The maximum wiring distance is 500ft. (160m). Note that the terminals on both the Pro Logic main unit and the wired remote display/keypad are numbered: Connect 1 to 1, 2 to 2, etc. Refer to diagram below. 3.75 " Remote Display unit 4 321 500 ft max 4.50 " Alternative Concealed Wiring If multiple remote display/keypads are installed: Never connect more than 2 wires to any terminal block.
