slaves Slaves are optional devices you can connect to expand the load-carrying capacity
of your Supra. Each slave follows the configuration and settings of the variable
stage to which it is connected.
For more information, read
Slave units
on page 11.
spikes
Spikes are short-term deviations or changes from a desired voltage level or signal.
These deviations can cause damage to electronic devices, or cause them to
malfunction. Spikes are often caused by sudden excess power, also known as
“power surges”, or by drops in power, knows as “brown outs”.
For more information, read
Understanding power surges and surge
suppression
on page 18.
staggered start See startup timer
startup timer The method Supra uses for balancing the initial startup load. Each Supra has a
configurable startup delay that it counts down before powering its loads.
For more information, read
Configuring the startup timer
on page 41.
temperature-
based duty
cycle
Duty cycle is a temperature-based method of controlling heating or cooling
elements using on and off durations.
For cooling elements, when the temperature is below the
set point
, the cooling
element is off. When the temperature is above the
set point
, the element switches
on for the
on duration
and then off for the
off duration
.
For heating elements, when the temperature is above the
set point
, the heating
element is off. When the temperature is below the
set point
, the element switches
on for the
on duration
and then off for the
off duration
.

Programming heating and cooling elements

temperature
setback
Temperature setback
allows you to automatically change the temperature
set point
for specific periods of time during the day. When
temperature setback
is enabled,
the Supra subtracts the
setback
amount from the
set point
. At the end of the
setback period, the Supra returns to the normal
set point
.
Temperature setback
is ideal for maintaining different method (DIF) and in
greenhouses. For more information, read
Programming the temperature setback
on page 71.
terminal block The part of the Supra where you connect the wires for incoming power, control
elements, and so on.
