安装维修保护说明
71.06953.01 - CN
* 自然通风型2.24 CF的烟道温控器
这个装置 有一个传感器位于排烟罩左侧,如果被堵塞或者出现通风故障,就会切断燃烧器中的气流。
这个情况下锅炉被锁定,显示屏显示错误代码E03(参见10章节)。
要马上点燃主燃烧器,请参见9章节.
*
过热保护传感器
过热温度传感器位于采暖供水管上的。当主换热器出水温度过高,发生过热时,过热保护功能启动切断燃烧器的燃气供应,锅炉将故障
停机,只有排除了产生异常的原因后,才可能重新点火。
按下按钮
( ), 至少2秒钟后松开,可使锅炉重新启动工作.
禁止将此安全装置取消或使其失效
*
火焰离子检测电极
火焰离子检测电极,确保燃气供气安全,防止不完全点火。(打开锅炉,从锅炉前方看,火焰点火及检测电极位于燃烧器的左侧),锅
炉在尝试3次点火后仍未点着火时,锅炉进入故障状态。
按下按钮
( ), 至少2秒钟重新启动锅炉后,进入正常运行状态.
*
水压开关
该装置检测系统压力,当压力超过0.5 bar时,才允许锅炉正常点火工作。
*
采暖模式水泵延时循环
采暖模式下,当燃烧器由于室内温控器或其他干预停止燃烧时,水泵将自动延时运行3分钟。
*
卫生热水模式下水泵的延时循环
卫生热水模式下,无卫生热水需求后燃烧器停止燃烧后,控制系统会控制水泵延时运行30秒。
*
防冻保护(采暖及卫生热水系统)
锅炉电控系统内置“防冻保护”功能。
当供水温度低于5℃时, “防冻保护”功能启动,锅炉开始运行,点火燃烧直至将供水温度加热至30℃。
只有当锅炉的电源、气源连接正常,且系统压力正常时,该功能才能正常启动。
*
系统水循环异常保护(可能的水泵堵塞)
如果锅炉主回路内缺水或水不循环,锅炉停机,同时显示屏显示故障代码E25(见第10节)。
*
水泵防粘死功能
在采暖模式下,若锅炉连续24小时无供热需求,水泵将自动启动并运行10秒钟。
该功能只有在锅炉电源连接正常时才可运行。
*
三通阀防粘死功能
锅炉连续24小时无供热需求时,三通阀将自动完成一个完整的行程。
该功能只有在锅炉电源连接正常时才可运行。
*
安全阀(采暖回路)
在采暖管路系统中设有3 bar安全阀,在系统超压时,通过泄水降压来保护锅炉
.
须将安全阀排水口接至专用的排水管或地漏处,严禁通过安全阀来排放采暖系统内的水,安全阀在发生超压泄水后,必须进 行检验,检验
合格方可继续使用.
注意: 即使卫生热水NTC传感器损坏,锅炉也可以提供卫生热水。在这种情况下,卫生热水温度将改由采暖NTC传
感器进行控制.
