CHI 说明
Chiller是CAREL为全面控制风/水和水/水冷水机组以及热泵机组而开发
的新解决方案。最高配置可管理每个回路2台压缩机(开/关式或BLDC
变频压缩机),最多可控制2个回路(在回路2上采用输入和输出点扩展卡)
。Chiller最突出的元素在于通过电子膨胀阀和无刷DC压缩机的集成管
理实现高效的全面控制,从而确保更好地保护压缩机以及更出色的稳
定性,机组的高效率。使用手操器可以利用移动设备进行无线通讯,
可集成到板载型,如果采用DIN导轨安装型,则需单独订购。

Description
Chiller is the Carel solution for complete management of air/water and wa-
ter/water chillers and heat pumps. The maximum conguration manages 2
compressors per circuit (On/O or BLDC), up to a maximum of 2 circuits (using
an expansion card for the inputs and outputs on circuit 2). The distinctive ele-
ment of Chiller is complete control of high-eciency units through integrat-
ed management of electronic expansion valves and brushless DC compressor,
thus ensuring greater compressor protection and reliability, together with
high unit eciency. The user terminal allows wireless connectivity with mo-
bile devices and is integrated into the panel-mounted models, or purchased
separately on DIN rail mounted models. The CAREL“APPLICA”app, available on
Google Play for the Android operating system, facilitates conguration of the
parameters and unit commissioning in the eld. The operation of Chiller is
described in the user manual + 0300053EN downloadable, even prior to pur-
chase, from the website www.carel.com.

Description
Chiller is the Carel solution for complete management of air/water and wa-
ter/water chillers and heat pumps. The maximum conguration manages 2
compressors per circuit (On/O or BLDC), up to a maximum of 2 circuits (using
an expansion card for the inputs and outputs on circuit 2). The distinctive ele-
ment of Chiller is complete control of high-eciency units through integrat-
ed management of electronic expansion valves and brushless DC compressor,
thus ensuring greater compressor protection and reliability, together with
high unit eciency. The user terminal allows wireless connectivity with mo-
bile devices and is integrated into the panel-mounted models, or purchased
separately on DIN rail mounted models. The CAREL “APPLICA”app, available on
Google Play for the Android operating system, facilitates conguration of the
parameters and unit commissioning in the eld. The operation of Chiller is
described in the user manual + 0300053EN downloadable, even prior to pur-
chase, from the website www.carel.com.

将控制器放到开孔中,轻轻按下侧面的卡扣,然后是前盖板,直到
控制器完全插入(侧面卡扣将弯曲,卡钩将控制器固定在面板上)。重
要:前盖板防护等级
IP65仅当下列条件满足后才能达到:
• 矩形开孔与水平面最大偏差:≤ 0,5 mm;
• 电控板金属片厚度:0.8 …2 mm;
• 应用垫圈的表面的粗糙度:≤ 120 μm。
注意:用于制造电控板的金属片厚度(或材料)必须足够确保安全和稳
定的安装产品。
Place the controller in the opening, press lightly on the side tabs and then on the front until fully inserted
(the side tabs will bend, and the catches will attach the controller to the panel). Important: IP65 front pro-
tection is guaranteed only if the following conditions are met:
•
maximum deviation of the rectangular opening from at surface: ≤ 0.5 mm;
•
thickness of the electrical panel sheet metal: 0.8-2 mm;
•
maximum roughness of the surface where the gasket is applied: ≤ 120 μm.
Note: the thickness of the sheet metal (or material) used to make the electrical panel must be adequate to
ensure safe and stable mounting of the product.

将控制器放到开孔中,轻轻按下侧面的卡扣,然后是前盖板,直到
控制器完全插入(侧面卡扣将弯曲,卡钩将控制器固定在面板上)。重
要:前盖板防护等级
IP65仅当下列条件满足后才能达到:
• 矩形开孔与水平面最大偏差:≤ 0,5 mm;
• 电控板金属片厚度:0.8 …2 mm;
• 应用垫圈的表面的粗糙度:≤ 120 μm。
注意:用于制造电控板的金属片厚度(或材料)必须足够确保安全和稳
定的安装产品。
Place the controller in the opening, press lightly on the side tabs and then on the front until fully inserted
(the side tabs will bend, and the catches will attach the controller to the panel). Important: IP65 front pro-
tection is guaranteed only if the following conditions are met:
•
maximum deviation of the rectangular opening from at surface: ≤ 0.5 mm;
•
thickness of the electrical panel sheet metal: 0.8-2 mm;
•
maximum roughness of the surface where the gasket is applied: ≤ 120 μm.
Note: the thickness of the sheet metal (or material) used to make the electrical panel must be adequate to
ensure safe and stable mounting of the product.
