Setting the Heat Fan Switch “Gas/Electric” (#4)
Note: The Lightstat TME must be powered Off and On in order to “read” a
change of switch settings.
This is often called the “Gas/Electric” switch. Consult the HVAC equipment
manufacturer instructions for details on how to set this switch.
When controlling fossil fueled equipment with a fan limit control you may want to
set this switch to the On position.
Note: The Lightstat TME will not bring on the fan in this setting during the heat
cycle.
Leave this switch set to Off for all other equipment.
