5.3.2 Configuration of sensor input as gate input To control the heat pump 2 options are available. Factory configuration is the option “sensor”. a) Control by sensor at terminal „F1“ b) Control by gate input at terminal „F1“ - The gate input hast to be made for electronic circuits. (relay with golden contacts) - After the heat pump is cut off a time out of 15 min.
