Temperature Range Lock 1 & 2

Range Lock is a group of Configurations which may be set to lock the unit into Start-Stop or Continuous Operation
for various setpoint ranges.

Two ranges are available for selection, Range Lock 1 and Range Lock 2. Each Range can be independently set to
lock it’s setpoint temperatures into either Start-Stop or Continuous operation.

Each Range has it’s own selectable minimum and maximum temperature, which define the span of the range. If
some setpoint temperatures are contained in both ranges due to range overlap, Range 1 will always have priority
over Range 2.

Typically, both Range Lock 1 and Range Lock 2 are used to control different setpoint ranges when IntelliSet is not
active.

For units with IntelliSet active, because each IntelliSet is generally programmed for a specific product, only Range
Lock 1 is used to hold the unit in either the Start/Stop or Continuous Operation, and Range Lock 2 is left off.

For example (see

), if Continuous Operation is ALWAYS required whenever the setpoint is between 28°F

and 55°F (-2.2°C and +12.8°C), Range 1 will be set for Continuous, with a Minimum Temperature of 28°F (-2.2°C) and
a Maximum Temperature of 55°F (-12.8°C).

Should Continuous Operation ALWAYS also be required with setpoints between -22 and 0°F (-30 and -17.8°C),
then Range 2 will be set for Continuous, with a Minimum Temperature of -22°F (-30°C) and a Maximum Tempera-
ture of 0°F (-17.8°C). Any setpoint outside of Range 1 or 2 will allow changes between Start-Stop and Continuous.

Figure 4.1 Range Lock Settings - Non Overlapping

The primary time that it is important to determine which range is to be Range 1 and which is to be Range 2 is when
the ranges overlap each other.

In example 2 (see

), the ranges have been set to lock all setpoints into Start-Stop, except for a small

range b32° and +42°F (0° and 5.6°C) where the unit will always operate in Continuous. Range 1 Minimum
Temperature has been set for +32°F (0°C), and Maximum Temperature of +42°F (5.6°C). Range 2 has been set for
a Minimum Temperature of -22°F (-30°C) and a Maximum Temperature of +89.6°F (32°C). The unit will switch to
Continuous when the setpoint is b32° and +42°F (0° and 5.6°C) because, when the ranges overlap each
other the Range 1 settings will take priority.
