Heating and Cooling Operation
The SPC-Elite can operate in either heating or cooling applications. Select the proper
application from the Startup menu.
• I n heating applications, the SPC-Elite control will use the Set Point less the Differential as a
starting point when temperature or sensor reading is dropping. Then, it will keep the relay
energized as long as the sensor is below the Set Point (Target).
• W hen the system value increases in heating applications, the relay will remain energized
until the Set Point (Target) is reached. Then, it will de-energize.
• I n cooling applications, the SPC-Elite control will use the Set Point plus the Differential as
a starting point when temperature is increasing. It will energize the output relay as long as
the sensor is above the Set Point (Target).
• W hen the system value falls in cooling applications, the relay will remain energized until
the Set Point (Target) is reached. Then, it will de-energize.
Output Light
The SPC-Elite has three lights, however, only the middle
output light is used. It follows the relay operation.
Whenever, Output Light is ON, the relay is energized.
Enable/Disable Input
The SPC-Elite will operate in heating or cooling modes only if the EXT- and EXT+ terminals
are shorted. If no external equipment or switch is connected to these terminals, leave the
factory installed jumper.
When the terminals are OPEN, the Target will display TSTAT OPEN.
On a sensor fault while the Enable/Disable terminals are open, the
control will follow the Enable /Disable state. However, the System
Sensor will display the fault condition weather Short or Open.
