, humidity load (R2) off
Dewing warning
When humidity get to dewpoint, after
【
dewing warning delay
】
controller enter dewing warning state. If
【
dewing warning way
】
is C, digital shows”E2” alarm, humidity load output stop, warning output (R1) on. If
【
dewing warning way
】
is V, digital
shows”99.9%”alarm, still output.
Timed control
Timing circle control:
◇
When enter timing load 1 timing 1, timing load 1(R5) on, timing load 2 (R4) off.
◇
When enter timing load 1 timing 2, timing load 2 (R4) on, timing load 1 (R5) off.
◇
When enter timing on 2, timing load 3(R1) on.
◇
When enter timing off 2, timing load 3(R1) off.
Load delay protection
◇
Controller power is on, all load output (R2 R3) run after load delay protection
；
◇
Running process, the temperature and humidity load (R2 R3) after downtime must be after load protection delay to start
again.
U
pper temperature and humisity limit protection
◇
U60=3, R1 is timing relay. When temperature or humidity beyond the limit, R1 turn on, R2 R3 off, R4 R5 still the same
◇
U60=2, R1 is timing function. When humidity or temperature beyond limit R1 turn on.
◇
U60=1, R1 is timing function, limit protecting function stop.
Sensor
◇When the sensor broken controller shows”E1”, humidity and temperature load off, warning output on.
