5.5 Configuring the sensor input as switching input 2 variants are available for regulating the heat pump. The operation mode “sensor” is the factory setting. a) Regulation via sensor on input “F1“ b) Regulation via switching input on input “F1 “ - The switching contact must be suitable for electronic switching.
6 Operation The heat pump is monitored and regulated by means of a digital regulation apparatus. The user has for this display units and operating elements at his disposal, via which the data can be set and called up. The user can set an “operation selection“ as well as “set values“ OPERATION SELECTION Heat pump AUTOMATIC...

6.2 Setting the Legionella function A one-off DHW heating, which will be started at adjustable intervals (days) t1, can be programmed into the control. Here, the DHW will be heated by the heat pump up to a set value S2. Should the set value not be reached within 4 hours, the heat-up cycle will be stopped by the program.
