| Wire Color | Terminal | Function |
|---|---|---|
| Red | R | Power |
| White | W | Heat |
| Yellow | Y | Cooling |
| Green | G | Fan |
Using this table, match each wire to its terminal. Ensure proper connections to avoid blinking issues.
Heat Pump Issues
A blinking heat light on your Honeywell Thermostat often indicates heat pump issues. Understanding these issues is crucial for ensuring your home stays warm. Below, we will explore two common problems related to your heat pump.
Heat Pump Defrost Mode
The heat pump defrost mode is a normal function. It prevents frost buildup on the outdoor unit. Here’s how it works:
- The system temporarily switches to cooling mode.
- Heat from the house is used to melt the frost.
- The process typically lasts a few minutes.
During defrost mode, you might see the heat light blinking. This is normal and should not cause concern. If the blinking continues for an extended period, it may signal a problem.
Heat Pump Malfunction
A blinking heat light could also indicate a heat pump malfunction. Common issues include:
| Issue | Description |
|---|---|
| Refrigerant Leak | Insufficient refrigerant can hinder heating. |
