A(10)
Indoor unit mode, the actual
operation of wind speed
and SCODE code
SMG2-2 represents the indoor unit mode O: stop, C: cooling, H: heating;
SMG1-1 represents the actual operating speed of the indoor fan (0- stop, 1-
low speed, 2- Middle speed , 3- high speed);
SMG1-2 represents the SCODE codes (0 ~ 15(F));
For example C3B means the high fan speed under cooling operation,
SCODE is 11
B(11) Indoor set temperature Tset Hydronic box: water inlet temperature Twi (°C)
C(12) Reserved
Hydronic box:
The first bit: Flow switch (0-disconnect; 1-connect)
The sencond bit: Hydronic box water pump (0-close; 1-open)
The third bit: Hydronic box heater (0-close; 1-open)
("110" means the flow switch detects water flow and closed, the water pump
turns on, and the electric heater off)
D(13) Reserved
Hydronic box:
The first bit: Microswitch (0-disconnect; 1-connect)
The sencond bit: 2-way valve interlock (0-disconnect; 1-connect)
The third bit: Floor heating main valve (0-close; 1-open)
("101" means the water tank micro switch closed, the two-way valve interlock
disconnected, and the floor heating main valve opened )
