Opstelling en installasie
Proper installation is crucial for the optimal performance of your thermostat. If you are unsure about any steps, consult a qualified HVAC technician.
1. Veiligheidsmaatreëls
- Turn off power to the heating and cooling system at the main fuse or circuit breaker panel before beginning installation.
- Ensure all wiring connections are secure to prevent electrical shorts or hazards.
2. Removing Old Thermostat
- Skakel krag na die HVAC-stelsel af.
- Verwyder die deksel van jou ou termostaat.
- Take a picture of the existing wiring connections for reference.
- 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).
- Carefully disconnect the wires and remove the old thermostat base from the wall.
3. Mounting the New Thermostat
- Feed the thermostat wires through the opening in the new thermostat base.
- Secure the thermostat base to the wall using the supplied screws and anchors.
- Ensure the base is level for accurate temperature readings.
4. Bedradingsverbindings
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:
- Stel op ELEC for Heat Pump or electric heat applications.
- Stel op GAS for gas or oil applications.
6. Battery Installasie
Your thermostat requires two "AAA" alkaline batteries for operation. These are typically included. To install:
- Open the battery compartment, usually located at the bottom front of the thermostat.
- Insert the two "AAA" batteries, ensuring correct polarity (+ and -).
- Maak die batterykompartement stewig toe.
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.

1. Aanpassing van temperatuur
- Gebruik die Pyltjie op knoppie om die ingestelde temperatuur te verhoog.
- Gebruik die Afpyltjie button to decrease the set temperature.
- The display will show both the current room temperature and the set temperature.
2. Fan Settings
The Fan switch controls the blower fan operation:
- OP: Die waaier loop aanhoudend, ongeag of die verhittings- of verkoelingstelsel aktief is.
- VOERTUIG: The fan runs only when the heating or cooling system is actively operating. This is the most common and energy-efficient setting.

The System switch controls the overall mode of your HVAC system:
- KOEL: The thermostat will activate the cooling system when the room temperature rises above the set temperature.
- AF: The heating and cooling systems are turned off. The fan can still be operated manually if set to ON.
- HITTE: The thermostat will activate the heating system when the room temperature falls below the set temperature.
Onderhoud
1. Battery vervanging
Replace the two "AAA" alkaline batteries annually, or immediately when the low battery indicator appears on the display. To replace:
- Maak die batterykompartement oop.
- Verwyder die ou batterye.
- Insert new "AAA" alkaline batteries, observing correct polarity.
- Maak die batterykompartement toe.
Note: Always use fresh alkaline batteries. Do not mix old and new batteries, or different types of batteries.
2. Cleaning the Thermostat
To clean the exterior of your thermostat, gently wipe it with a soft, damp lap. Moenie skuurmiddels of oplosmiddels gebruik nie, aangesien dit die afwerking of interne komponente kan beskadig.
