minimum set
point
Minimum set point is the temperature at which an actuator is at its minimum
position. When the temperature is below the set point, the actuator closes
completely.
For more information, read Programming actuators on page 49.
off at
Off at is a temperature setting for variable stages. When the temperature is below
the off at temperature, the fan is off. When the temperature rises above the off at
temperature, the fan runs at the idle speed until the temperature rises to the idle
at temperature.
For more information, read Programming variable stages on page 46.
on full at
For variable stages, the fan is on full (100% speed) at and above this temperature.
Also called the ‘range temperature’.
For more information, read Programming variable stages on page 46.
PIN
Personal identification number. A PIN is a unique four-digit number similar to a
password. When security is enabled, users must enter the PIN before changing
any configuration or settings. This prevents unauthorized access to the control.
For more information, read Using PIN security on page 66.
relay
A relay is an electromagnetic switch that is either on (closed) or off (open).
set point
temperature
Set point is the temperature at which a relay stage switches on or off.
For more information, read Programming heating and cooling elements on page
54.
See also actuator set point and curtain set point.
spikes
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 9.
terminal block
The part of your PEC Plus where you connect the wires for incoming power,
control elements, and so on.
For more information, read
PEC Plus layout on page 13.
voltage
Electromotive force or potential difference, usually expressed in volts.
