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.

furthest remote display/keypad is 500 ft (160m).
