speed.
3) The range of Ts is 16 - 30 ºC.
4) Indoor fan speed can be adjusted for low, medium, high and auto.
LOW TEMPERATURE PROTECTION OF INDOOR COIL
a
)
If Ti1 ≤ 2 ºC for 2 minutes, then MTV1 is turned off. DA2=0VDC. If indoor fan is set for low speed, then it will run at
medium speed. If it is set at medium or high speed, then it will keep running at the same speed.
a)
If Ti1 ≥ 5ºCfor 2 minutes, then MTV1 is turned on.DA2 is calculated by delta T. Indoor fan runs at set speed.
FAN MODE
a) Indoor fan runs at the set speed while heater, MTV1, MTV2, AUX1 and AUX1 are turned off.
b) Indoor fan speed can be adjusted to low, medium and high.
HEAT MODE
Heat mode without electrical heater (300047=0)
a)
If Tr ≤ Ts - 1 ºC, then heat operation is activated and MTV2 is turned on.
DA3 is open at 10Vdc for 2 min. Then check Ti3,
MS300080=0,
If Ti3<=28ºC (300017 setting), fan is turned on at low speed; DA3 is on at 10VDC;
If 28ºC (300017 setting)<Ti3<28
(
3000017 setting
)
+4ºC, fan and DA3 are kept original state;
If Ti3 ≥ 28
(
3000017 setting
)
+4ºC, fan runs at set speed. DA3 output is from minimum setting(300016setting) - 10Vdc based
on Delta T3 and T4 and setting; if Ti1 sensor is damaged, Fan runs at set speed.
MS300080=1
DA3 output is based on heating water flow reading and setting PID calculation. The output is minimum output
(Modbus300015 setting)-10VDc;
MS300080=2
DA3 output is based on heating pressure difference setting (MS300085) and 4-20mA input 3 reading (MS400008) PID
calculation. The output is minimum output (Modbus300015 setting)-10VDc;
b) If Tr > Ts+1 ºC then heat operation is terminated and MTV2 is turned off. DA3 is 0VDC. Indoor fan is turned on low speed;
c) The range of Ts is 16 - 30ºC.
d) Indoor fan speed can be adjusted to low, medium, high and auto.
OVER-HEAT PROTECTION OF INDOOR COIL IN HEAT MODE
a)
If Ti3 ≥ 75 ºC, then MTV2, DA3, AUX2 and EH are turned off, indoor fan runs at high speed, even in standby mode.
b)
If Ti3 < 70 ºC, then unit will maintain its original state.
c)
If Ti3 temperature sensor is damaged, the protection mode will be overridden
DEHUMIDIFICATION MODE
a)
Ts=24ºC;
b)
If Tr ≥ 25ºC for 30S, then MTV1 will be ON for 3 minutes, and then OFF for 4 minutes. DA2 is turned on 3times of
minimum opening. Fan is running at auto speed.
c)
If 16ºC≤ Tr < 25ºC, then MTV1 will be ON for 3 minutes, and then OFF for 6 minutes. DA2 is turned on 2 times of
minimum opening. Fan is running at auto speed.
d)
If Tr < 16ºC, then MTV1 will be turned ON for 4 minutes and then OFF for 10 minutes. DA2 is turned on minimum
opening. Fan is running at auto speed.
AUTOMODE
Fan is turned on at medium speed. Check Tr and Ts in 30S;
if Ts>Tr+3ºC for 30S, the unit is turned on in heat mode;
if Tr-3 ºC<Ts<Tr+3 ºC for 30S, the unit is turned on in fan mode;
If Ts<Tr-3 ºC, , the unit is turned on in cool mode;
If unit is working at heat mode or Fan mode, if Tr-Ts>3.0ºC, MTV2 , MTV1 and DA3 are OFF more than 3 minutes, working
mode will be changed to cooling mode;
