Intermittent Fan
Temperature conditions can vary widely between the thermostat
location and the extremities of the space the thermostat serves.
This air stratification problem can be especially pronounced
during mild outdoor conditions when long periods elapse
between space conditioning demands from the thermostat. This
intermittent fan operation can also improve the performance of
air cleaning or special filtration systems that locate the cleaning
or filtration media at the return air side of the fan. If the FAN
hasn’t been on for an hour, the fan will start cycling based on the
times that the user enters in the set up of Intermittent Fan.
To turn intermittent fan on select FAN on main screen and then
INTERMITTENT, then press OFF next to ON TIME. Press the
up and down arrows ▲▼ on the right hand side to adjust the
fan on time, this is the amount of time you want the fan to be
energized. Default is OFF. Ranges are OFF, or 5-20 minutes in
5 minute increments. Press the box to the right of OFF TIME
this is the time the fan will be off. Press the up and down arrows
▲▼ on the right hand side to adjust the fan off time. Ranges
are 5-40 in 5 minute increments. Fan ON and OFF cycles will
continue until the fan has been energized by a call for heating or
cooling.
