Keypad Functions

• TIME
• Press (time backward) or (time forward) to set the current time. Press and hold the arrow for fast time set (15 minute step).
• DAY
  Press (SET DAY) to set the day of the week. The day of the week display advances (initially SU for Sunday). Press again to step throught the days of the week until the correct day is displayed.
• SWING ( HVAC cycling rate)
  This feature allows you to set the desired variance in temperature between the 3M-22 setting and the room temperature required before the heating or cooling system will turn on—from 0.5° to 2.0° F (.25° to 1° C). For example, if HVAC CYCLING is set to 2.0° F and the 3M-22 is set to 70°F, the heat cycle will start when room temperature drops to 68°F. Similarly, the cooling system will start when the room temperature increases to 72°F. The HVAC then runs and will shut off at the target.
• FILTER CHECK FILTER ALERT
  The 3M-22 is programmed to remind you when the HVAC air filter needs changing. It is set to remind you every 90 days. The Check Filter indicator blinks when your filter limit is reached.

• To UNLOCK:
• Touch and hold HOME for 3 seconds. The LOCK icon will go out.
• CALIB
• Your thermostat was accurately calibrated at the factory to ±1° F of actual ambient temperature. You do have the option, however, to change the display temperature to match that of a previous thermostat, or to match another thermostat already in your home. The range of change is from -6°F to+6°F or -3°C to +3°C.
• To change your Thermostat Calibration:
• Press CALIB (under the EVEN icon)
• Use the + / – to adjust the displayed temperature up or down, as desired. The temperature display will show the modified temperature reading that will be displayed on the HOME screen and used as the new room temperature. Press HOME to store your settings.
• HOLD
• This will make your 3M-22 act like a non-programmable thermostat. It will hold the target temperature you set indefinitely until you turn HOLD off. Take care using the HOLD function as the program is now bypassed. To set a hold target temperature, press HOLD and use the +/- buttons to select your hold temperature. The HOLD icon will display on the HOME screen indicating you have changed the Target Temperature. The system will HOLD this temperature until you return to the manual screen. To turn off hold press HOLD again. HOLD is also canceled when you set the mode to OFF.
• TEMPORARY override Touch the + / – buttons to select your desired temporary Target Temperature. The TEMPORARY icon will display indicating you have modified the programmed Target Temperature for the current Time Slot only. It goes back to the program target at the next period. Also once in temporary, when the target is set the same as the programmed target for that Time Slot, the word TEMPORARY will go out.

Other Functions

• SAVE ENERGY Button The “Save Energy” feature on the 3M-22 provides a simple, easyto-use way to help you manage your energy use. SAVE ENERGY automatically adjusts your target temperature up in COOL or down in HEAT by 4oF. To use Save Energy, press the Save Energy button in the upper left corner of the unit. The screen will now read “Save Energy”. To return to normal operation, press the “Save Energy” button again. This is useful to save energy if you are gone for a short time.
• FAN Switch The fan control is normally in AUTO mode, meaning that the fan operates
  automatically with the HVAC system and the thermostat. When the fan switch is in ON, the fan will run
  continuously until switched back to AUTO.
  NOTE: Fan ON function is available in the OFF mode to allow simple ventilating.
• EMER HEAT If you set your 3M-22 for HEAT PUMP with auxiliary heat, EMER function is available with a switch under the top cover on the right. If you switch EMER to ON, your HEAT PUMP is disabled and auxiliary heat is your sole source of heat. This manual override stays active until you switch EMER off. Auxiliary heat is more expensive than the heat pump so use EMER only if the heat pump cannot keep up or is defective.-
• RESET button The RESET button re-boots the 3M-22 processor. It does not effect the user programs that have been stored in permanent memory.
• Compressor Protection The 3M-22 has a minimum cycle time of 4 minutes to protect your compressor in cool and in heat pump (if you have one). During this time the compressor will not come on until the 4 minute delay is over.
• Simple Screen This display mode limits the amount of information on screen and limits the functions to just the + and – buttons. To access the Simple Screen hold down both + and – buttons at the same time for 10 seconds. To leave the Simple Screen hold down both + and – buttons at the same time for 10 seconds.
