` CHANGE SET POINT
1. SP (set point) display reads current set point in degrees F.
2. Press the SET/ENTER button to change the set point. Use left and right
arrows to navigate to digit you wish to change. Press up/down arrow to
change digit. When complete, press SET/ENTER again to set the new value.
` SET BOILER ON/OFF TEMPERATURE
1. There are two parameters that are required to set up the hysteresis around
the set point. These parameters are HY1 and A1.
2. To access HY1: Press the DISP button until HY1 appears. Factory default
setting is 10.
3. To navigate to A1: Press the DISP button until A1 appears. Factory default
setting is -5.
