26. un through the steps outlined in 7 1 If the problem is not solved please investigate the following Step 1 Ensure the sensor probe is inserted fully into the port with tight metal to metal contact The sensor should be coated with silicone heat transfer paste to ensure optimal heat transfer Step 2 Check the sensor for damage cracking etc If damaged replace Step 3 Test the sensor in a cup of hot water together with another sensor or thermometer A variance of several degrees is common particularly for the high temperature sensor Step 4 Change the position of the sensor on the connection block swap with another sensor and see if the temperature reading is the same If a strange reading is still provided by the sensor then it may be faulty and should be replaced If the reading is normal but the other sensor now provides an incorrect reading it may be a problem with the connection block requiring replacement of the controller 7 2 Miscellaneous Problems Problems related to strange operation of functions incorrect cycling of the pump or continuous error reporting may simply be due to incorrect function settings Step 1 Use F14 to reset the system to default settings then re configure each setting as required Step 2 Turn OFF any relays and functions that are not required Step 3 Ensure sensors and consumers are connected properly Step 4 Thoroughly read this instruction manual again If the problem persists please contact
