Air Conditioning Functions
Cooling Mode
Valve Contact Operation
- Valve contact opens when:
- Room temperature ≥ (Set temperature + 0.5°C)
- Valve contact closes when:
- Room temperature ≤ (Set temperature – 0.5°C)
Fan Speed Settings
- AUTO (Automatic) → HIGH (High speed)
- MED (Medium speed) → LOW (Low speed)
Auto Fan Speed
Three-stage auto fan speed logic in cooling mode
| Δ = (Room – Set temp) | Fan speed |
|---|---|
| Δ ≥ 3.0 | High |
| 2.5 ≤ Δ ≥ 2.0 | Maintain Current Speed |
| Δ = 1.5 | Medium |
| 1.0 ≥ Δ ≥ 0.5 | Maintain Current Speed |
| Δ ≤ 0 | Low |
Main unit
ON, Heater: OFF
Heating Mode
2-Pipe/DX Valve Operation
- Valve contact opens when Set temp ≥ (Room temp + 0.5°C).
- Valve contact closes when Set temp ≤ (Room temp – 0.5°C).
- Heater contact ON, Main unit contact ON.
4-Pipe/Electric Heater Operation
- Heater contact opens when Set temp ≥ (Room temp + 0.5°C).
- Heater contact closes when Set temp ≤ (Room temp – 0.5°C).
- Valve contact OFF, Main unit contact ON.
- Fan delay: After shutdown in heating mode, low-speed contact delays 30 sec before closing.
Selectable Fan Speed
- Auto → High → Medium → Low
1 Auto Fan Speed
3-stage auto speed logic for heating mode
| Δ = (Room – Set temp) | Fan speed |
|---|---|
| Δ ≥ 3.0 | High |
| 2.5 ≤ Δ ≥ 2.0 | Maintain Current Speed |
| Δ = 1.5 | Medium |
| 1.0 ≥ Δ ≥ 0.5 | Maintain Current Speed |
| Δ ≤ 0 | Low |
Extended Models
Additional Features for DX (Direct Expansion) AC Units
- 3-minute delay start protection for 3-way valve (optional high-current RELAY for compressor control)
- OSC. louver setting: Controls main unit RELAY → ON/OFF for louver function
Jumper Setting Table
| Parameter | Position | Default | Setting Range |
|---|---|---|---|
| 1 : Power-on Behavior | SW1:5&4 Jumper | Power-off | SW1:5=Short, SW1:4=Short (Power-off) * SW1:5=Open, SW1:4=Short (Power-off) SW1:5=Short, SW1:4=Open (Power-on) SW1:5=Open, SW1:4=Open (Memory) |
| 2: Valve (3-way/Compressor) Delay Protection | SW1:3 Jumper | No Delay | * SW1:3=Short (No Delay) SW1:3=Open (3 min) |
| 3 : Coil Configuration | SW1:2 Jumper | 2-Pipe/DX | * SW1:2=Short (2-Pipe/DX) SW1:2=Open (4-Pipe/Electric) |
| 4 : Unit Interlock/ Louver Contact Function | SW1:1 Jumper | Unit Interlock | * SW1:1=Short (Unit Interlock) SW1:1=Open (Louver Function) |
Note
- Configure jumper settings by cutting (Open) or connecting (Short) the corresponding SW1 jumpers on the control box.
- For louver (air direction) function [DX model]: Set SW1:1 to Open. The unit interlock contact will be converted to louver contact output (dry contact).
- * indicates factory default setting.
FAQ
How do I change the temperature setting?
