WHD46型智能溫濕度控制器通用技術(shù)指標(biāo)如下： 此類溫濕度控制器可控制一路、二路或三路溫濕度，每一路溫濕度傳感器對(duì)應(yīng)一組(二個(gè))繼電器輸出觸點(diǎn)，其中一個(gè)觸點(diǎn)用于控制加熱器，實(shí)現(xiàn)升溫或除濕控制，另一觸點(diǎn)用于控制風(fēng)扇，實(shí)現(xiàn)排風(fēng)控制。當(dāng)傳感器或加熱器發(fā)生故障時(shí)，控制器會(huì)發(fā)出報(bào)警信號(hào)。 控制器中還可設(shè)置溫濕度控制的回滯量，即調(diào)節(jié)設(shè)備的啟動(dòng)條件與停止條件之差。如圖6所示，以加熱升溫為例，當(dāng)環(huán)境溫度降低到預(yù)先設(shè)置“加熱啟動(dòng)溫度”以下時(shí)，控制器輸出觸點(diǎn)導(dǎo)通信號(hào)，加熱器工作，環(huán)境溫度逐漸上升;當(dāng)環(huán)境溫度上升至“加熱停止溫度”以上時(shí)，控制器輸出觸點(diǎn)斷開信號(hào)，加熱器停止加熱。根據(jù)經(jīng)驗(yàn)，回滯量一般設(shè)置在4～10(℃或RH%)范圍內(nèi)較合適。
