Configuring the main control functions
Before configuring the variable and relay stages, you need to configure the main control functions.
Main control functions include items such as temperature units that the PEC Plus needs to know
before you configure the variable and relay stages.
Main control functions include:
Clock/time – the PEC Plus has a clock that counts time
Temperature units – degrees Fahrenheit or Celsius
Temperature probes – how many and where they are connected
Hysteresis – the number of degrees above or below the set point that equipment switches on or
off
Setting the clock
The PEC Plus has a clock that keeps track of the time for the daily high and low temperatures and
the growth curves.
If there is a power failure, or you need to adjust for daylight savings time, you will have to change
the clock. The PEC Plus uses 24-hour time. The table below shows some common standard times
and their 24-hour equivalents.
