Wiring of the Thermostat
The proper limit of the thermostat should be selected based on the protection function of the
electric heater.
Firstly, short-circuit the ON/OFF control signal output terminals of AC contactor 1 and AC contactor
2, and then connect them with the thermostat in series. Do not let the temperature of the external
wall of the tank-type electric heater too high (see the diagram below for more details). After that,
apply heat-conducting paste on the sensing probe and then insert it to the sensing hole to sense the
temperature of the external wall of the tank-type electric heater.
Wiring of the Tank-type Electric Tank
The tank-type electric heater with proper power output should be used and the heating pipe should
be installed at the water inlet side of the unit.
Three-phase wiring for the electric heater should be supplied by the user themselves. A new
electric box is recommended to be used. See the diagram below for more details.
When protection function of the thermostat is required, the sensing probe applied with heat-
conducting paste should be inserted into the sensing hole after wiring of the electric heater has been
finished.
