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 actuator relays
on page 78.
off at
Off at
is a temperature setting for variable stages.
For cooling 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 variable heating stages, when the temperature is above the
off at
temperature,
the heater is off. When the temperature falls below the
off at
temperature, the
heater operates at
min heat
until the temperature falls to the
set point
temperature.
For more information, read
Programming variable stages
on page 75.
on full at For variable cooling stages, the fan is on full (100% speed) at and above this
temperature. For variable heating stages, the heat mat is
on full at
and below this
temperature.
For more information, read
Programming variable stages
on page 75.
PIN
PIN is an acronym for personal identification number. A PIN is a unique four-
digit number similar to a password.
When security is enabled, each user must enter their PIN before changing any
settings or acknowledging alarms. This allows the Supra to track who has
performed each change and prevents unauthorized access to the control.
For more information, read
Programming alarm settings
on page 90.
pulse counter A pulse counter it is an electronic counter that counts the number of electric
pulses (switch closures). The Supra’s pulse counter can count the electronic
pulses emitted by a water meter with pulse output.
relative
humidity
Relative humidity is the quantity of water vapor the air contains compared to the
maximum amount it can hold at that particular temperature.
For example, a relative humidity of 60% means the air contains 60% of the
maximum moisture it can contain at the present temperature. The warmer the air,
the more moisture the air can hold.
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.
