Temperature Sensors The ECOMMAND 4 utilizes 10K ohm thermistor type sensors. Three sensors (water temperature, air temperature and solar temperature) are included. If the ECOMMAND 4 is being used to control a solar heating system, the solar sensor is required. The sensors are provided with a 15 ft. cable. If a longer cable is required, contact the Hayward service dept. for information on suitable cable types and splices. See page 3 and the diagram below for installation information.
