Setpoint Temperature:
The setpoint temperature is the desired maintain temperature for the
water pipe.
Based on the measured control temperature, the ACS-PCM2-5 will switch the relay output to
maintain the system at the desired setpoint.
Range:
35°F (2°C)–50ºF (10°C)
Default:
40ºF (4°C)
Deadband:
If the control temperature is above the setpoint temperature plus deadband, the relay
output is turned off. If the control temperature is below the setpoint temperature, the output is
turned on.
Range:
1°F (1°C)–10°F (6°C)
Default:
5ºF (3°C)
