MCDONNELL&MILLER控制器150S系列介紹
The Series 150S is available as an alternative for Series 150 LWCO controls that contain mercury switches. Please keep in mind that in a replacement or repair situation you do not have to change out the entire control. A head replacement (i.e. 1 50S-HD) is all that's required.
There may be additional letters such as 'B', 'R',‘RL'， etc. in the sales catalog designation of the control. These additional letters designate tapping locations and sizes which have no affect on which head mechanism to purchase. All head mechanisms are interchangeable and can be installed on any body.
‘MD'Models
The‘MD' model should be used as a replacement head when the boiler operating pressure is less than 50 psi. These were created to provide a control with factory settings to compensate for the narrowing of setpoints. The larger differential between pump on and burner off reduces the potential for nuisance burner shutdown.
150S 系列可作為包含水銀開(kāi)關(guān)的 150 系列 LWCO 控制器的替代品。 請(qǐng)記住，在更換或維修情況下，您不必更換整個(gè)控件。 只需更換一個(gè)磁頭（即 1 個(gè) 50S-HD）。
控件的銷售目錄名稱中可能還有其他字母，例如“B”、“R”、“RL”等。 這些額外的字母指定了攻絲位置和尺寸，這對(duì)購(gòu)買哪種頭部機(jī)構(gòu)沒(méi)有影響。 所有頭部機(jī)構(gòu)都是可互換的，可以安裝在任何身體上。
‘MD’型號(hào)
當(dāng)鍋爐工作壓力低于 50 psi 時(shí)，應(yīng)使用“MD”型號(hào)作為更換頭。 創(chuàng)建這些是為了提供具有出廠設(shè)置的控件，以補(bǔ)償設(shè)定值的縮小。 泵打開(kāi)和燃燒器關(guān)閉之間較大的差異降低了有害燃燒器關(guān)閉的可能性。
