The best place for the thermostat is the room where you spend the most time, in many cases the living room or kitchen. Place the thermostat about one and a half metres above the floor, not in the sun and not on an outside wall.
If your thermostat has a dead band, your installation is, as it were, 'at rest'. The thermostat only switches on when, for example, the difference deviates more than 2˚C from the set room temperature.
Most people find that the ideal room temperature is between 19 and 22 degrees Celsius.
To change the temperature setting on the Honeywell Chronotherm IV T8665A thermostat, follow these steps: 1. Press the Heat/Cool Settings key to switch between heat and cool settings. 2. Use the increase ▲ or decrease ▼ buttons to adjust the temperature setting. For example, if the cool setting is currently set at 84°F, the cooling equipment will operate when the room temperature is above 84°F. 3. If you want to temporarily override the current schedule period and change the temperature setting until the next schedule period, press the increase ▲ or decrease ▼ buttons until the desired temperature setpoint is displayed. The temporary temperature setting will be indicated as "Temporary" on the display until the next period begins or when you cancel the temporary setting. 4. If you want to change and hold the temperature setting indefinitely, you can also do so by pressing the increase ▲ or decrease ▼ buttons until the desired temperature setpoint is displayed. Remember, if you make a mistake or want to start over, you can always press the appropriate key to return the display to normal. Please let me know if you need further assistance.
