Parameter Setting Method
Function: To set Cut OFF Set Point for Compressor1
Relay.
In this mode Compressor1 will be ‘ON’ if the Control
(Main) Probe Temperature reaches or goes above
‘‘Set Point + Differential” (SP1 + P4) and Compressor1
will be ‘OFF’ if Control (Main) Probe Temperature
reaches or goes below Set Point (SP1).
Example:
When Set Point1 is 0.0°C and Differential is 2.0°C. If
the Control (Main) Temperature reaches or goes
above 2.0°C (0.0°C + 2.0°C), Compressor will be ON.
Compressor will be OFF when Control (Main)
Temperature reaches or goes below 0.0°C.
