(6) Attentions: Connect the wires strictly according to the wiring terminal diagram. Use three-core shield
cable (3×0.75mm
2
) to connect to the temperature sensor. Use common two-core cable (2×0.75mm
2
) to
connect the flow switch to connect to the NO contact of the switch, i.e. the opening point when waterless.
Two buttons can be connected to the external remote start and stop.
(7) If the customer wants linked control of the water pump, connect the water pump as shown in the diagram,
where an intermediate relay is required. If the function of linked control of water pump is not needed,
ensure that the water pump starts before starting the machine.
CAUTION: An independent power supply box needs to be equipped with the power supply of the water
pump.
(8) The wiring ports for remote start/stop, flow switch, cool/warm switch, water pump linked control, alarm
indication are reserved in the electrical cabinet of the unit.
(9) Passive inching button is used for remote start and stop, and the flow switch must be connected to the
NO contact, or the machine cannot be started.
Passive holding switch is used for cool/warm switch, e.g. common selection switch. Controls of large
power electrical appliances such as water pump and user electric heating must be interfaced with a relay,
or the PCB might burn out. Other outputs can be directly connected to indicator lamps or alarms.
