After the tenth stage running finishes, machine automatic shutdown;
Heating of each stage:
During the return air temperature in each stage≤(design temperature-return difference desired temperature), start compressor;
During return air temperature >=the design temperature in each stage, close compressor;
The hydrofuge in each stage:
In heating process, if meet hydrofuge condition, enter hydrofuge, heat up heating and hydrofuge function can be carried out simultaneously.During hydrofuge, line control machine lower right shows " hydrofuge ".
Note: above drying room temperature and humidity set point are pressed the setting value in ladder; As keep constant temperature to be set to 0 hour, cancel the heat temperature raising in this stage.
4) wet-emitting blower control logic: this control logic (stepwise heating and heating mode) under heating mode is effective.Parameter 15 wet-emitting blower=0: control by humidity is set; Parameter 15 wet-emitting blower=1: automatically control.
Logic when humidity being set controlling: when humidity >=humidity is set, wet-emitting blower leaves; When humidity≤(arrange humidity-heat return difference), wet-emitting blower closes; Logic when automatically controlling: startup meets the following conditions simultaneously: 1. compressor available machine time >=hydrofuge working time; 2. humidity >=arrange humidity; 3. wet-emitting blower interval time >=electric expansion valve action cycle is set.Meeting following arbitrary condition closes: 1. humidity≤wet-bulb temperature return difference arranges-heat return difference; 2. wet-emitting blower working time >=hydrofuge interval time.If while selecting to be heating mode, humidity is set by the setting value of parameter 6; While being ladder heating if select, by the setting value in ladder.
