1. Installation Steps
User Guide can be downloaded from: heating.danfoss.com.
1. Installation must be done by an authorised
electrician.
2. The room thermostat should be installed at approx.
1.5 m above oor and where the eects of sunlight,
draught or other heat sources (eg. TV’s) are avoided,
see g. 1.
3. First of all, carefully remove the cover, see g. 2.
4. Connect the wire before mounting the back plate to
the wall box using the enclosed screws. Then mount
the cover to the back plate, see g 3.
2. Wiring
1. Dimensions, see g. 4
2. Wiring diagram, see g. 5 and g. 6
3. Follow the illustrations to complete the wiring:
1) RC-T4, see g. 5
2) RC-T2, see g. 6

Hi Indicating temperature
higher than 50°C
4. Notes
1. Correct wiring is essential; using instrument to con-
rm L and N before wiring is recommended.
2. Don’t remove too much of the insulation cover from
the wire to avoid short circuit caused by the naked
wire touching the metal 86 size mounting wall box.
3. Don’t let the screw press or touch the wire when
using screw to x room thermostat in wall box. A
short-circuit risk exists if the wire insulation cover is
damaged by the screw, and if the naked wire con-
nects with the screw.
4. If walls must be painted, mount the room thermostat
after painting, to avoid dust or paint material pen-
etrating the room thermostat and thus damaging
the PCB.
5. The max load of relay is 3 A (resistive) or 1 A (induc-

tive). The relay will be damaged if the load exceeds
the limit.
6. Don’t cover the thermostat, for instance by hanging
towels directly in front of it.
7. The room thermostat should be connected to the
corresponding actuator and valve in individual room
temperature control.

1. 安装指南
可通过以下网址下载《用户指南》：heating.danfoss.com.cn
1.必须由经过专业培训合格的电工进行安装。
2.室内温控器应当安装在地面上方大约1.5米处，并且
避免受到日光、气流或者其他热源（例如：电视）的
影响。请见图1。
3.首先，小心拆下前盖。请见图2。
4.在将背板固定至暗线箱之前，使用随附的螺钉连接导
线，然后将盖子安装至背板。请见图3。
2. 接线
1. 外形尺寸，请见图4。
2. 接线端子，请见图5和6。
3. 请按照以下说明完成接线：
1）RC-T4时，请见图5。
2）RC-T2时，请见图6。

3. 错误代码
显示屏说明E1 室温传感器故障
EE EEPROM故障
Lo 房间温度低于0℃
Hi 房间温度高于50℃
4. 注意事项
1. 正确接线至关重要；接线之前，建议使用仪器确
定L与N。
2.请勿从导线上拆下过多绝缘护套，以免裸露导线接
触金属86盒造成短路。
3. 使用螺钉固定暗线箱中的室内温控器时，避免螺
钉按压或接触导线。如果螺钉将导线绝缘护套损
坏，以及裸线与螺钉连接，则有可能造成短路。
4. 如果必须对墙壁涂漆，请在涂漆后安装室内温控
器，以免灰尘或涂料渗入室内温控器，从而损坏
PCB。
5. 继电器的最大负载为3A（纯阻性）或1A（感
性负载）。如果负载超过限值，则继电器将会受
损。
6. 请勿覆盖温控器，例如：将毛巾直接挂在温控器
前部。
7. 进行分室温控时，温控器所在房间与阀门所在的
回路要对应。
