Technology: This feature allows the thermostat to “learn” how long the furnace
and air conditioner take to reach programmed temperature settings, so the temperature is reached at
thetimeyouset.Forexample:SettheWaketimeto6am,andthetemperatureto70°.Theheatwill
come on before 6 am, so the temperature is 70° by the time you wake at 6. The message “Recovery”
is displayed when the system is activated before a scheduled time period.
Compressor Protection: This feature forces the compressor to wait a few minutes before restarting,
topreventequipmentdamage.Duringthewaittime,themessage“Wait”isdisplayedonscreen.
Auto Changeover (RTH7500 only): This feature is used in climates where both air conditioning
and heating are used on the same day. When the system is set to Auto, the thermostat automatically
selects heating or cooling depending on the indoor temperature. Heat and cool settings must be at
least 3 degrees apart. The thermostat will automatically adjust settings to maintain this 3-degree
separation.
CAUTION: To avoid possible compressor damage, do not use Auto Changeover if the
outside temperature drops below 50°F (10°C).
