Control Logic For 4-Pipe System
Note: 4-pipe system must always be equipped with 2 valves.
COOL MODE
When unit is turned on in cooling mode.
If Tr ≥ Ts + 1ºC (Modbus 300033 setting), MTV1 is turned on. AUX1 is closed. Fan is turned on at setting speed. DA2 is turned
on at 10 VDC for 2 minutes, then check Tr and Ts:

DA2 output is from minimum (Modbus 300016 setting) ~10 VDC based on Tr and （ Ts +2 ） PID calculation.

If Tr < Ts-1ºC (Modbus 300033 setting), then cool operation is terminated and MTV1 and AUX1 are turned off. Indoor
fan runs at set speed. DA2 output is 0 VDC.

When unit is turned off, MTV1 and AUX1 are off. DA2 is 0 VDC. Fan is turned off delaying 30s.

The range of Ts is 16 - 30ºC

Indoor fan speed can be adjusted to low, medium, high and auto.
LOW TEMPERATURE PROTECTION OF INDOOR COIL IN COOLING MODE
If Ti1
≦
2 ºC for 2 minutes

MTV1 is turned off.

DA2 is set to 0%.

Indoor fan is turned on to Medium speed if fan runs at low speed.
If Ti1
≧ 5ºC for 2 minutes

MTV1 is turned ON.

DA2 is set to original status.

Indoor fan is changed to setting speed.
FAN MODE
Indoor fan speed can be adjusted for low, medium and high. If fan speed is set auto by Modbus, fan is running at low speed.
HEAT MODE
Without Electrical Heater
（
Modbus300047=0
）
When unit is turned on in heating mode.
When Tr ≤ Ts - 1 ºC (Modbus 300033 setting), MTV2 and AUX2 is turned on. DA3 is at 10 VDC for 2 minutes, then check
Ti2:

If Ti2 < 28ºC (Modbus 300017 setting), fan is turned on at low speed. DA3 is at 10 VDC.

If 28ºC<Ti2< 28
（
Modbus 3000017 setting
）
+4ºC, fan is on at original state. DA3 is at original state.

If Ti2 ≥ 28
（
Modbus 300017 setting
）
+4ºC, fan is on at setting speed. DA3 output is from minimum (Modbus 300016
setting) ~10 VDC based on Tr and
（
Ts-2
）
PID calculation.

If Ti2 sensor is damaged, fan runs at setting speed.

When Tr > Ts +1 ºC (Modbus 300033 setting) ºC, MTV2 and AUX2 is turned off. DA3 is at 0 VDC. fan is turned on at
lowest speed.

When unit is turned off, MTV2 and AUX2 is turned off. DA3 is at 0 VDC. Fan is turned off delaying 2 minutes.
With Electrical Heater as booster
（
Modbus300047=1
）
When unit is turned on in heating mode.
When Tr ≤ Ts - 1 ºC (Modbus 300033 setting), MTV2 and AUX2 is turned on. Fan is turned on at setting speed. DA3 is at
10 VDC for 2 minutes, then check Ti2:

If Ti2 < 28ºC (Modbus 300017 setting), EH is turned on. DA3 is at 10 VDC.

If 28ºC<Ti2< 28
（
Modbus 300017 setting
）
+4ºC, EH is kept at original state. DA3 is at original state.

If Ti2 ≥ 28
（
Modbus 300017 setting
）
+4ºC, EH is turned off. DA3 output is from minimum (Modbus 300016 setting)
~10 VDC based on Tr and
（
Ts -2
）
PID calculation.
