Display if the minimum operation time is satisfied
, when compressor stops, “Min. Running Time
Elapsed” must be ‘YES’.
Note: when the compressor has oil temperature sensor, the oil temperature conditions must be satisfied
so the compressor can start. When it has no oil temperature sensor, the remaining time for oil heating is
displayed.
It depends on the unit
It displays the refrigerant type in the top left of the screen.
To start the unit must meet the following conditions:
①
“Delaying Restart” needs to be “NO”, if it is “YES”, the delay time to start the unit is not reached.
②
“Water Temperature Allow Compressor Start” needs to be “YES”, if it is “NO”, the current water
temperature does not meet the startup conditions of compressor.
③
“Oil Temp. Allow Compressor Start” needs to be “YES”, if it is “NO”, the current oil temperature does
not meet the startup conditions of compressor.
Shutdown must meet the following conditions:
“Min. Running Time Elapsed” needs to be “YES”, “NO” indicates the delay time for shutdown is not
reached.
1) Status information- display of temperature and pressure
Figure 6.7
2) Status information-input status:
Input status page:
“ON” means the input point is closed, OFF means the input point break. “Compressor
overload protection switch”, when the machine is overloaded, “compressor overload protection switch”
input state switches
to “ON” and unit enters fault protection state. Normal state of compressor overload
protection switch is “OFF”. Protection on standby is “ON”.
