🔍 Operational Function Review
- on/off: Main power switch to kickstart or shut down the connected central unit.
- mode: Adjusts running conditions across COOL, DRY, FAN, or HEAT profiles.
- TEMP (▲ / ▼): Changes targeted temperature values in 1° intervals.
- FAN: Steps through manual blower speeds or places the fan into automatic regulation mode.
- SLEEP / Lock (🔑): Restricts button accessibility to prevent unauthorized adjustments or engages energy-efficient sleep timers.
📦 Complete Kit Breakdown
- Wired Wall Interface / Thermostat (Top Left): Features a dual-digit red LED screen to adjust temperature, configure fan rates, and diagnose system error codes.
- Main Indoor PCB Control Board (Right): The main computer board containing five heavy-duty black relays (to control fan speeds and compressor cycling), capacitors, transformer coils, and jumpers.
- Power Step-Down Transformer (Bottom Left): A low-voltage transformer block labeled Model: CF2. It converts high-voltage mainline current down to a safe 220V/50Hz to 24V output to power the motherboard and thermostat safely.
- Ambient & Coil Thermistor Sensors (Bottom Right): Dual copper-head and plastic-coated temperature sensor cables that plug into the main board to read exact room and indoor coil temperatures.
- Heavy-Duty Signal Cable (Top Left): A thick, grey, multi-core shielded cable that safely routes data signals between the wall thermostat and the indoor motherboard over long distances.
