MCDONNELL&MILLER控制器150S系列介绍

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 系列可作为包含水银开关的 150 系列 LWCO 控制器的替代品。 请记住，在更换或维修情况下，您不必更换整个控件。 只需更换一个磁头（即 1 个 50S-HD）。

控件的销售目录名称中可能还有其他字母，例如“B”、“R”、“RL”等。 这些额外的字母指定了攻丝位置和尺寸，这对购买哪种头部机构没有影响。 所有头部机构都是可互换的，可以安装在任何身体上。

‘MD’型号

当锅炉工作压力低于 50 psi 时，应使用“MD”型号作为更换头。 创建这些是为了提供具有出厂设置的控件，以补偿设定值的缩小。 泵打开和燃烧器关闭之间较大的差异降低了有害燃烧器关闭的可能性。
