Page 24: Main Logics
SHERPA SHW Sanitary water heat pump 11.4 MAIN LOGICS 11.4.1 Water temperature difference for compressor starting Parameter 1 “water temp. difference TS6” is used to control the compressor on or off. When down tank temperature T2 is lower than setting temperature TS1-TS6, the compressor will work to heat the water until reaching the setting temperature TS1. -
Page 25: Electrical Heater
SHERPA SHW Sanitary water heat pump The logic starts to calculate t2 only when T3 has reached TS3. It’s possible to set the interval between the disinfection cycles (parameter 21). If the unit is “OFF”(and also if ON/OFF contact is opened), the disinfection starts with the same logic of “ON” unit. If the unit is disconnected from the power supply, the disinfection cycle will not occure. -
