Parameter Name/Description 
SMART RECOVERY — Transitions the conditioned space from one programmable 
temperature period to the next with 1°F increments of the heating setpoint or with 1°F 
decrements of the cooling setpoint, so that by the time the next period starts, the 
setpoints are at the desired temperature. The purpose of the gradual transition is to use 
less energy by preventing staging up (because of a higher demand) to higher stages. The 
transitions occur in a linear fashion over the smart recovery time period. 
•  If you start a temporary hold in the middle of a smart recovery, the setpoints of the 
temporary hold are used. 
•  If a temporary hold is already active during the time that smart recovery would have 
been started, a smart recovery does not start. 
•  If the temporary hold ends in the middle of what would have been a smart recovery, 
the smart recovery starts where it would have been in the linear progression at the 
same time as when the temporary hold was not active.  
FAN ON WITH W — Supplies a fan output demand as soon as a W1 or W2 output 
demand is active. 
REVERSING VALVE — Defines whether the ON state of the reversing valve is used for 
heating or cooling when COMPRESSOR TYPE is set to HP.   
•  When the ON state of the reversing valve is used for cooling, the signal is typically 
referred to as a O.    
•  When the ON state of the reversing valve is used for heating, the signal is typically 
referred to as a B demand.  
•  If COMPRESSOR TYPE is set to HP, the thermostat configuration may be limited for 
the following:  
•  Humid-MiZer™ dehumidification 
•  Humidifier operation 
•  Occupancy output 
SPACE TEMP OFFSET — Calibrates the internal space temperature sensor. 
SPACE HUM OFFSET — Calibrates the internal relative humidity sensor.  
AUTO CHANGEOVER — The minimum time between switching from heat-to-cool or from 
cool-to-heat demands, when in AUTO MODE. The timer begins when the MINIMUM OFF 
TIMER expires.
