Precautions
①W1-W8: Connected to the thermostat, low voltage, regardless of null line and fire line,
W1 must be connected to the master thermostat, W1 corresponds to an area.
② R1-R8: Connected electric heating actuator, R1 corresponds to W1, R2 corresponds to W2, and so on,
R1-R4 can be connected to two electric heating actuators respectively, the total current does not exceed 5A.
