9. Set Limits
The EV-3000 Back-Up System requires setting of a High Limit and a Low Limit at which cool/heat stages
will turn on. To determine where to set the High Limit and the Low Limit, first decide on a target
temperature of the house. This is usually the target temperature of the primary controller. Then set the
High Limit to a temperature several degrees above the desired target temperature. Set the Low Limit to a
temperature several degrees below the desired target temperature. Note: It is recommended that the
High Limit be at least 10º above the room’s target temperature and that the Low Limit be 10º below
the room’s target temperature.
