Question 1

How to change the programmed temperature for night settings on the Emerson thermostat 1F85U42PR?

Accepted Answer

To change the programmed temperature for the night period (Sleep) on your Emerson thermostat 1F85U-42PR, you need to access the heating programming menu. This period is called Sleep and is set by default to 10:00 PM with a temperature of 62 °F (17 °C).

Steps to change the night temperature in heating mode:

Press the System button and select the Heat position
Press the Menu button to access the main menu
Use the arrow buttons to select Schedule, then press Next to enter the programming menu
The hour icons will blink. Continue pressing Next to move through the periods: Wake, Leave, Return until you reach Sleep
When you are at the Sleep period, press Next to move to the temperature setting (the setpoint icons will blink)
Use the arrow buttons (up/down) to adjust the new desired temperature for the night (range: 7 °C to 37 °C / 45 °F to 99 °F)
Continue pressing Next to finish programming for all days of the week
Press Exit at any time to save your changes and return to the home screen

If your thermostat is set with 2 periods per day (Leave/Return instead of 4), the procedure remains the same but the periods will be different. Similarly, to change the night temperature in cooling mode (Cool), follow the same steps by first selecting Cool instead of Heat. The heating and cooling settings are programmed separately and independently of each other.

The new programmed temperature will apply to all days of the week unless you have set a specific 7-Day program for certain days. You can check and modify the default programming settings (menu 01 and 02) if you wish to change the number of periods per day or the type of programming (7 days, 5-1-1 days, or non-programmable).
