Can't find the answer to your question in the manual? You may find the answer to your question in the FAQs about the Emerson 1F85U-22PR below.

Where is the best location to place the thermostat?

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.

What is the dead band of a thermostat?

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.

What is the ideal room temperature?

Most people find that the ideal room temperature is between 19 and 22 degrees Celsius.

How do I adjust the temperature on my Emerson 1F85U-22PR thermostat?

Press the "Up" or "Down" arrow button to set the desired temperature. The display will show the new temperature setting.

Why is my thermostat not turning on my HVAC system?

Ensure that the thermostat is in the "Heat" or "Cool" mode and set to the desired temperature. Check if the circuit breaker for your HVAC system is on and make sure the power switch on your thermostat is set to "On."

How can I program different temperature settings throughout the day?

Press the "Program" button, then use the arrow keys to select the desired time period (e.g., "Wake," "Leave," "Return," or "Sleep"). Adjust the temperature using the arrow buttons, then press "Set" to save the setting.

Can I set a vacation mode on my thermostat?

Yes, to set a vacation mode, press the "Menu" button, go to "Program," and scroll to "Vacation." Adjust the start and end dates using the arrow keys, and set the desired temperature for the vacation period.
