①
The temperature adjustment cycle represents each execution cycle of the judgment of load or
unload. If it is set to be 60s, then system judges the unit temperature and checks if it needs to load or
unload every 60 seconds. If it is necessary, system will execute it immediately. After 60 seconds, system
judges it again, and repeats the process;
②
Temperature control range: it means the precision of temperature control, for example, the
factory setting is 2
℃
,if temperature is within ±0.5
℃
of control temperature, the unit does not execute the
loading/unloading action;
③
The target value of temperature control: it represents the target value of water temperature
control;
④
Temperature of compressor startup: it represents the control water temperature need to meet
one condition when compressor starts;
⑤
In cooling mode, when control water temperature is higher than startup temperature, the
compressor can start; in heating mode, when control water temperature is lower than startup temperature,
the compressor can start;
⑥
Limit of load: the maximum load of unit can be set. 0-without limit of maximum load, 1-
maximum load is up to 75%, 2- maximum load is up to 50%.
Timer setting of startup or shutdown It will only display
when control mode is “timer”.
