How does Energy Efficient Recovery™ (EER™) work?
Energy Efficient Recovery™ is an energy saving feature. During a set back period (or set up in cooling), it allows the thermostat to
look up to two hours ahead to determine when to turn on the heating (cooling) system. During this time period, the second stage is
locked out to allow the first (and most efficient stage) to bring your home to the desired temperature.
How does my remote indoor sensor work?
The remote indoor sensor (part #9020i) can be used to improve the comfort of your home. When used in conjunction with the local
sensor on the thermostat, the two sensors average the sensed temperature and control to that average temperature.
You also can use the remote sensor in a stand-alone situation when you want to control the temperature in a remote room but have
the thermostat in a secure location.
When would I need a remote indoor sensor?
Large rooms are ideal for remote sensors. Installing a remote sensor across from the thermostat will provide constant comfort through-
out the living space.
How does my remote outdoor sensor work?
The remote outdoor sensor (9025i) can be used to aid in the comfort of your home or simply as a sensing device to inquire about out-
door conditions. In most applications, the thermostat will have a display of the temperature sensed by the remote outdoor sensor. With
your heat pump system, the remote outdoor sensor can help determine when to turn on the second stage of heating for optimal com-
fort. The outdoor sensor also allows you to choose AUTO humidity sensing (see page 16) to minimize condensation on your windows.
Where should I install a remote outdoor sensor?
The remote outdoor sensor should be installed on the northern wall of your home, away from direct sunlight or other heat sources that
may affect its sensitivity.
