PDS 2系(xi)列(lie)是用(yong)(yong)于樓宇自動化應用(yong)(yong)的溫(wen)度控(kong)制(zhi)(zhi)器(qi)。控(kong)制(zhi)(zhi)器(qi)具有(you)用(yong)(yong)于 Modbus RTU 通信的 RS-485 連接。控(kong)制(zhi)(zhi)器(qi)支持 Pt1000 溫(wen)度傳(chuan)感器(qi)。執(zhi)行(xing)器(qi)可以是 0...10 V 控(kong)制(zhi)(zhi)執(zhi)行(xing)器(qi)和/或熱執(zhi)行(xing)器(qi)或 3 點執(zhi)行(xing)器(qi)。該控(kong)制(zhi)(zhi)器(qi)有(you)兩個適用(yong)(yong)于不同應用(yong)(yong)的產品：PDS 2-V 和 PDS 2-H。

PDS 2-V專為空(kong)氣處理單元控(kong)(kong)(kong)(kong)制(zhi)(zhi)和(he)溫(wen)度(du)控(kong)(kong)(kong)(kong)制(zhi)(zhi)而(er)設計。適用(yong)于恒值控(kong)(kong)(kong)(kong)制(zhi)(zhi)和(he)房間/排(pai)氣溫(wen)度(du)補(bu)償控(kong)(kong)(kong)(kong)制(zhi)(zhi)。還可用(yong)于生活水(shui)溫(wen)控(kong)(kong)(kong)(kong)制(zhi)(zhi)。為了防止加熱盤管結(jie)冰，可以(yi)將防凍恒溫(wen)器(qi)（例如 JVS 24）連接(jie)到控(kong)(kong)(kong)(kong)制(zhi)(zhi)器(qi)。

PDS 2-H專為基(ji)于室外溫(wen)(wen)度(du)的(de)加熱水回路溫(wen)(wen)度(du)控(kong)制(zhi)而(er)設計。控(kong)制(zhi)器根據室外溫(wen)(wen)度(du)的(de)五點(dian)曲線控(kong)制(zhi)供(gong)水溫(wen)(wen)度(du)。通(tong)過(guo)室溫(wen)(wen)補償可(ke)以(yi)提高(gao)控(kong)制(zhi)精度(du)。例如，ECO 模式(shi)功能和(he)供(gong)水溫(wen)(wen)度(du)補償可(ke)用于在夜間(jian)節省供(gong)暖能源。
