3.6变频器防干扰处理
变频器很容易产生干扰源，使温湿度波动加剧，严重时会使控制器误动作，影响空调机正常的逻辑控制，因此，无论从硬件还是软件方面都必须考虑**变频干扰。布线时，动力线与控制线分开，变频器必须可靠接地，热电阻pt100应使用桥式接法。软件方面应对各模拟量输入接口进行滤波处理等措施。这样基本能**变频器所带来的干扰。
3.7人机界面
采用全中文的触摸屏显示器，操作简易，显示内容丰富。可实时监控各处的温、湿度参数，设定室内温、湿度值，定时开、关机功能，显示实时故障与历史故障。为安全起见，对一些重要参数设置多级密码保护。
3.8安全保护
机组主要设置如下保护：送风机变频故障、送风机风压故障、电加热高温保护、用户外部故障连锁、电源相序保护、压缩机高、低压保护、压差报警、加湿故障。
