Digital Write
You can Run/Stop and change the setting value of thermo-hygrostat by using digital write, as follows.
Digital write setting parameters are as follows :
PORT Connected PORT number 0 ~ 255
STATION Set STATION
ADDRESS Use only 0014, 0015 0014 : Operate as reservation mode,
0015 : Dehumidification, Humidification, Cooling, Heating, System Operation.
EXTRA1 Don't care
EXTRA2 When ADDRESS is 0015, Set operation contents
0 – Dehumidification Operating, 1 – Humidification Operating, 2 – Cooling Operation, 3 – Heating Operation, 4 – System Operation.
Write example 1)
Port : 0, Station : 1, ADDRESS : 0014
If you set as above and write digital value, you can run/stop(ON/OFF) the reservation operating(according to designated reservation time) of thermo-hygrostat.
Write example 2)
Port : 0, Station : 1, ADDRESS : 0015, Extra2 : 0
If you set as above and write digital value, you can run/stop(ON/OFF) the dehumidification operating of thermo-hygrostat.
Write example 3)
Port : 0, Station : 1, ADDRESS : 0015, Extra2 : 4
If you set as above and write digital value, you can run/stop(ON/OFF) the thermo-hygrostat.
Analog Write
You can change setting value of temp/humidity and reservation time etc for thermo-hygrostat by using analog write as follows.
Analog write setting parameters are as follows :
PORT Connected PORT number 0 ~ 255
STATION Set STATION
ADDRESS 0001 ~ 0015 0001 ~ 0010 : Change setting value,
0011 ~ 0013 : Current time, Set reservation time,
0014 : Operate as reservation mode,
0015 : Dehumidification, Humidification, Cooling, Heating, System Operation.
EXTRA1 Don't care
EXTRA2 When ADDRESS is 0011 ~ 0013, Designate month/day : 4 digits High 2 digits – Month, Sub 2 digits – Day (Ex : If it is 1123, it means November 23),
When ADDRESS is 0015, set operation contents : 0 – Dehumidification Operating, 1 – Humidification Operating, 2 – Cooling Operation, 3 – Heating Operation, 4 – System Operation.
Write example 1)
Port : 0, Station : 1, ADDRESS : 0001
If you set as above and write analog value, you can change setting temperature of thermo-hygrostat as designated value(00 ~ 50).
Write example 2)
Port : 0, Station : 1, ADDRESS : 0001
If you set as above and write analog value, you can change setting humidity of thermo-hygrostat as designated value(00 ~ 99).
Write example 3)
Port : 0, Station : 1, ADDRESS : 0011, Extra2 : 1109
If you set as above and write analog value as 1630, you can change current time of thermo-hygrostat as November 9 16:30.
Write example 4)
Port : 0, Station : 1, ADDRESS : 0012, Extra2 : 1109
If you set as above and write analog value as 1700, you can designate start time of reservation operating for thermo-hygrostat as November 9 17:00.
