1. Matikan kuasa kepada sistem HVAC.
2. Tanggalkan penutup termostat lama anda.
3. Take a picture of the existing wiring connections for reference.
4. Label each wire with the terminal designation it was connected to (e.g., W for Heat, G for Fan, Y for Air Compressor, R for Power).
5. Carefully disconnect the wires and remove the old thermostat base from the wall.

3. Memasang Termostat Baharu

1. Feed the thermostat wires through the opening in the new thermostat base.
2. Secure the thermostat base to the wall using the supplied screws and anchors.
3. Ensure the base is level for accurate temperature readings.

4. Sambungan Pendawaian

Connect the labeled wires to the corresponding terminals on the new thermostat base. Refer to the wiring diagram provided with your unit for specific connections. Common connections include:

• R (or Rh/Rc): 24VAC Power (often red wire)
• W: Heat (often white wire)
• Y: Air Compressor / Cool (often yellow wire)
• G: Fan (often green wire)
• O / B: Heat Pump Reversing Valve (if applicable)

Note: If your system has separate transformers for heating and cooling, ensure the Rh and Rc terminals are connected correctly, or remove any jumper if instructed by your system's wiring diagram.

5. System Type Selection (Gas/Electric)

Locate the Electric/Gas switch inside the thermostat unit. Set this switch according to your heating system type:

• Tetapkan kepada ELEC for Heat Pump or electric heat applications.
• Tetapkan kepada GAS for gas or oil applications.

6. Pemasangan Bateri

Your thermostat requires two "AAA" alkaline batteries for operation. These are typically included. To install:

1. Open the battery compartment, usually located at the bottom front of the thermostat.
2. Insert the two "AAA" batteries, ensuring correct polarity (+ and -).
3. Tutup petak bateri dengan selamat.

Note: Some models may have a protective tab to remove before first use.

7. Completing Installation

Once wiring and battery installation are complete, carefully snap the thermostat front cover onto the base. Restore power to your HVAC system at the main fuse or circuit breaker panel.

The ProTech White-Rodgers 1F78-144 is a non-programmable thermostat designed for straightforward temperature control.

1. Melaraskan Suhu

• Gunakan Anak panah atas butang untuk meningkatkan suhu yang ditetapkan.
• Gunakan Anak panah ke bawah butang untuk menurunkan suhu yang ditetapkan.
• Paparan akan menunjukkan kedua-dua suhu bilik semasa dan suhu yang ditetapkan.

2. Fan Settings

The Fan switch controls the blower fan operation:

3. Tetapan Sistem

The System switch controls the overall mode of your HVAC system:

• KEREN: Termostat akan mengaktifkan sistem penyejukan apabila suhu bilik meningkat melebihi suhu yang ditetapkan.
• MATI: The heating and cooling systems are turned off. The fan can still be operated manually if set to ON.
• HABA: Termostat akan mengaktifkan sistem pemanasan apabila suhu bilik jatuh di bawah suhu yang ditetapkan.

Penyelenggaraan

1. Penggantian Bateri

Replace the two "AAA" alkaline batteries annually, or immediately when the low battery indicator appears on the display. To replace:

1. Buka petak bateri.
2. Keluarkan bateri lama.
3. Insert new "AAA" alkaline batteries, observing correct polarity.
4. Tutup petak bateri.

Note: Always use fresh alkaline batteries. Do not mix old and new batteries, or different types of batteries.
