also will be displayed at the controller but the unit continues normal operation.
(16) The leaving and entering water temperature of the solar panel and also the solar panel temperature are
detected by sensors installed at the inlet pipe, outlet pipe and solar panel of the solar system respectively.
Theses sensors are mainly used to control the water pump of the hot water of the solar system. When the
entering water temperature sensor fails, this error will be displayed at the controller and the unit continues
normal operation. When other two sensors fail, this error also will be displayed at the controller and the
water pump of the solar system will stop.
(17) The remote room temperature is detected by the sensor installed at the room, which is mainly used to
control the input capacity of the compressor through room temperature setting. When the main unit is
controlled through the room temperature and this sensor fails, all loads except the water pump of the solar
system and the electric heater of the water tank will stop. However, when the main unit is controlled through
the leaving water temperature, if this sensor fails, this error will be displayed but the main unit will resume
normal operation.
(18) Only when the control function of the thermostat has been activated through the wired controller, then the
thermostat can switch run modes among cooling, heating and shutdown, otherwise, the unit will run as per
the run mode set by the wired controller.
(19) The gate control function can be set to be "On" or "Off" at the function setting page of the wired controller.
When this function has been activated and it is detected that the gate control card has been drawn out, the
unit will shut down and will tell any key operation of the controller is invalid. Then, if it is detected that the
gate control card has been inserted in, the unit will resume normal operation.
(20) The flow switch of the solar system is mainly used to judge the water flow. When the flow rate is too low,
the flow switch will disconnect and immediately the water pump of the solar system will stop. This error will
be displayed at the controller and is unrecoverable. When this error is cleared, upon power on again, the
unit will restart.
Items 15~ 20 are control parameters input by the field installed equipment.
