temperature drops below the recovery temperature 60 . Another system will be not affected.
3) T4, T3B and T3A: when the temperature sensor is detected to suffer open circuit or short circuit, fault alarm will occur.
When the main unit suffer fault of temperature sensor: the main unit and subordinate units will be shut down.
When the subordinate unit suffer fault of temperature sensor: the unit will be shut down, but other subordinate units will
not be affected.
4
Detection of current of the compressor A2 (protection code P4)
5
Unit outlet water temperature sensor (fault code E4)
Under refrigeration mode and heating mode, conduct adjustment according to the magnitude of unit outlet water
temperature.
Adjustment range of constant speed capability: ON and OFF.
6
Total outlet water temperature sensor (fault code E3)
Only the main unit is valid, and the subordinate units are invalid.
Under refrigerating mode and heating mode, conduct adjustment according to the magnitude of total outlet water
temperature. Adjustment range: Load, stabilize, unload, Emergency Stop.
7
Spot check. The operating status of outdoor system can be observed through spot check, and specific display contents are
as shown in the following figure:
Display contents of
operating mode : 1. cooling; 2. heating; 4. pump; 8. Stand-by
Display contents of number of online units : the main unit can display the number of online units, and the subordinate
unit displays 0.

Each modular part of modular unit has the same electric control function, and the main unit and subordinate units can be
set through address code on the electric control board. The address code 0 # is provided as the main unit. The priority of
being the main unit is given to the unit with digital compressor, and other addresses are subordinate units. Only the unit is
chosen as the main unit, its electric control can activate such functions as direct communication with the wired controller,
refrigerating and heating capability adjustment, pump control, auxiliary electric heater control, total effluent temperature
detection and water flow switch detection.
