Hayward Pro Logic® Models: PL-PS-4 PL-PS-8 PL-PS-16 PL-PS-16V Installatio - Page 22

Temperature Sensors The Pro Logic utilizes 10K ohm thermistor type sensors. Three sensors (water temperature, air temperature and solar or dual equipment spa temperature) are included. If the Pro Logic is being used to control a solar heating system, the solar sensor is required. If dual equipment will be used, the dual equipment spa sensor (spa temperature for "Pool and Spa-Dual") is required. If both solar and dual equipment are desired, another temperature sensor must be purchased separately. The sensors are provided with a 15 ft. cable. If a longer cable is required, contact the Hayward service dept. (908-355-7995) for information on suitable cable types and splices. See Temperature Sensors on page 6 for directions on installing sensors. POOL/SPA SENSOR AIR SENSOR SOLAR SENSOR optional DUAL EQUIPMENT SPA SENSOR optional Wired Remote Display/Keypad The Pro Logic main unit can connect to a maximum of 3 remote wired display/keypads. Wired display/keypads must be 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. Connect screw terminals "1" to "1", "2" to "2", etc. Wired Remote Display unit 432 1 500 ft max If multiple remote display/keypads are installed: Never connect more than 2 wires to any terminal block. Two remotes can be wired back to the Pro Logic main unit or the second display/keypad (and third, if applicable) can be "daisy chained" with one display/keypad wired to the next. The maximum wire run from the Pro Logic main unit to the furthest remote display/keypad is 500 ft (160m). 19
