6.4.4. AUTO MODE (CHILLER MODELS)

Start-up process:
Start-up conditions: Water intake temperature < (Setpoint temperature - Auto mode
temperature differential); Compressor stop time ≥ Compressor delay time, then it enters Heat
mode.
If the water intake temperature > (Setpoint temperature + Auto mode temperature differential);
and the Compressor stop time ≥ Compressor delay time, then it enters Cool mode.
Stop process:
Compressor 1 stops, Compressor 2 stops 10s later, the fans stop and the water pump stops 30s
later.

6.4.5. DEFROST FUNCTION

The controller will supervise the temperature in the evaporators when the machine is in
heating mode, and decide whether need to defrost according to the working time of the
machine in that continuous low temperature state. In other words, the defrosting
calculagraph begins to count when the machine evaporator temperature is lower than
"defrost start temperature", and turns on the defrosting
when the value of time reaches "defrost start time". The
calculagraph will be cleared if the evaporator
temperature is higher than "defrost start temperature"
when counting, and it begins to count again when the
evaporator temperature is lower than "defrost start
temperature". In other words, the value of defrosting
calculagraph shows the continuous low temperature working time of the machine (For 2
compressor systems as long as a compressor system satisfies the conditions for defrosting,
the other system will also defrost).
