Control function instruction
Temperature control
Cooling control:
◇When the temperature≥【setting temp.】+【temperature difference】,and temperature load (R3) stop time meet【temp. load
delay protection】,temp. Load on;
◇When the temperature≤【setting temp.】,temp. Load (R3) off;
Heating control:
◇When the temperature≤【setting temp.】-【temperature difference】,and temperature load stop time meet 【temp. Load delay
protection】, temp. Load (R3) on;
◇when the temperature≥【setting temp.】, temp. Load (R3) off;
Temperature correct
◇When temperature value is different from sensor install place,【Temperature correct】can correct it,
Adjustment range is ±9.9%.
Humidity control
Dehumidifition control：
◇when humidity ≥【setting humidity】+【humidity difference】, and humidity load (R2) stop time meet【humidity delay load
protection】, humidity load on；
◇when humidity ≤【setting humidity】, humidity load (R2) off；
Humidification control：
◇When humidity ≤【setting humidity】-【humidity difference】, and humidity load (R2) stop time meet【humidity delay load
protection】, humidity load (R2) on；
◇when humidity≥【setting humidity】, 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.
Humidity correct
◇When humidity value is different from sensor install place,【Humidity correct】can correct it, adjustment range is ±9.9%.
Timed control
Timing circle control:
◇When enter timing load 1 timing, timing load (R5) on, timing load (R4) off.
◇When enter timing load 2 timing, timing load (R4) on, timing load (R5) off.
Sensor
◇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.
◇Do not change Sensor or connecting ways, when the power is on.
Fault alarm
When the sensor broken controller shows”E1”, humidity and temperature load off, warning output on.
