3) If 16 ºC < =Tr(Room air temperature) < 25 ºC, MTV1(Chilled water motorized valve) will be on ,
after 90 second also AUX2(Cold water free contact) will be ON for 10 minutes, after both will be
OFF for 12 minutes.
4) If Tr(Room air temperature) <16 ºC, MTV1(Chilled water motorized valve) and AUX2(Cold water
free contact) will be turned off for 4 minutes, and check the temperature one more time. At the end of
the above dehumidification cycle, system will decide the next dehumidification control option.
5) Indoor fan will run at low speed throughout the dehumidification process.
6) With dehumidification mode, “ Low temperature protection” is valid.
Humidistat control
Humidistat control: Humidistat must be connected only to the master unit .
1) AUX1(hot water free contact) is always off.
2) If humidistat contact is ON(close), indoor fan and MTV1 will be ON, and AUX2(cold water free
contact) will be on after 90 seconds delay.
3) If humidistat contact is OFF(open), indoor fan,MTV1 and AUX2(cold water free contact) will be
OFF.
4) Indoor fan will run at 1
st
speed when RH< 70%, or 3
rd
speed when RH>= 70%.
5) During humidistat dehumidification, RH setting range is 40-70%. By pressing temperature Up/Down
buttons to adjust RH set point. Every time by pressing temp Up/Down button, 2% would be adjusted.
6) When Hr(room humidity)
≤
Hs(setting humidity)-2%, no matter how is room temperature, indoor fan,
MTV1 and AUX2 would be close.
7) When Hr(room humidity)
≥
Hs(setting hu 2%, unit would work with dehumidification cycle.
8) During dehumidification cycle, the default setting temperature is 22
℃
. When Tr(room temperature)
≥
22
℃
, unit would work with low cooling. When Tr(room temperature)
＜
22
℃
, unit would be on
with 10min, and off with 6 min. When Tr(room temperature)
≤
16
℃
, unit would stop working.
9) Humidistat control is set only by wire wall pad.
10) With dehumidification mode, “ Low temperature protection” is valid
7.4.2.5 Auto mode
This function is study to obtain maximum comfort for occupant people , for this reason our priority is to
have :
1)
Auto mode is selectable only from master unit or wired wall pad connected with master unit. If
selected Auto mode from master unit, slave units would not change with other mode. System working
condition, like cooling, heating or fan, should be same with master unit or master wired wall pad.
2) Temperature set point must be selectable from user, range is 5-30°C. If PR setting is activated, range
is same as PR setting
3) Cooling or heating mode will be decided from machine logic.
4) Fan speed will be decided from machine logic.
5) When mode is changed, the setting temperature is set with default
25 ºC.
6) Cooling/heating mode, the min working time is 30 minutes.
7) Every time the unit is turned on in auto mode, AUX1(Hot water free contact), AUX2(Cold water free
contact) and fan are off. MTV1(Chilled water motorized valve) are on. After 5 second fan run at min
speed .
8) After 20 sec machine check Tr and compare with Ts, and check Ti1(Chilled water coil temperature).
Default setting temperature is 25 ºC.
9) If Tr(Room air temperature) > Ts(Setting tempe2 ºC, cool operation is activated,
MTV1(Chilled water motorized valve) is already on , AUX2(Cold water free contact) will be on after
90second. Unit would work with Anti-hot air setting in cooling mode.
10) If ( Ts -2 °C ) ≤Tr ≤ ( Ts+2°C) , AUX2(Cold water free contact) , AUX1(hot water free contact)
MTV1(Chilled water motorized valve) will be off , fan remains on at min speed.
