Programming the parameters
Programming the parameters explains parameters 1 to 23 and how to program them. For
information about parameter 0, read Selecting the operating program on page 39.
Programming the group set point, parameter 1
The group set point is the target or desired temperature for the zone. It is also the temperature
tracked by the individual stages. The individual set points for each variable and relay stage will be
adjusted relative to the group set point for that zone. For example, if you lower the group set point
by 5 degrees, the set points for the variable and relay stages will also be lowered by 5 degrees.
Make sure you set the group set point before setting the individual set points.
For a more-detailed description of how all settings work together, read Understanding how the SEC-
HD operates on page 26.
Use temperature override to test your high and low temperature alarms instead of
adjusting the group set point. In temperature override mode, the alarm relay and
status LEDs both operate as if they were in a real alarm situation. For more
information, read Using temperature override mode on page 41.
