7.4 FACTORY PROGRAMMED SUPERHEAT
The stand alone EXV control is pre-programmed for 10°F superheat. The following dip
switch settings must be set at the time of coil installation.
7.5 SUPERHEAT OFFSET DIP SWITCH SETTINGS
Although the above superheat set point is considered to be the most efficient set point
for each air handler, installation conditions can drastically effect the measurement of
superheat by the air handler control. For this reason the following dip switch settings
have been provided to enable flexibility for various installation conditions.
7.6 EXV STEP DIP SWITCH
The EXV dip switch has an optional 500 or 1600 steps setting. This dipswitch should
currently be in the 500 step position only. Rheem does not currently supply 1600 step
EXV’s. The dipswitch makes the control forward compatible with a 1600 step EXV for
possible future use.
