5.5kw to60KW Swimming Pool Heat Pump / Electric Water Heater - Digital Display Precision Thermostat 1_HL-600

Important: Mismatch between the water pump and thermostat or insufficient flow can cause the heating tube to run dry and be damaged. Pump requirements: for units below 11KW, the supporting water pump must be at least 750W and provide a flow of no less than 13 cubic meters per hour. For units above 11KW, the supporting pump must be at least 1.1KW with a flow of at least 18 cubic meters per hour. Startup/shutdown sequence: always power the water pump first, then switch on the thermostat; when shutting down, turn off the thermostat and wait 10 seconds to 1 minute before stopping the pump. Heating guidance: 1KW of thermostat power will heat approximately 1 cubic meter of water; outdoor swimming pools will require greater power to achieve the same heating effect.
