[. . . ] It can be used to control gas and oil boilers, a variety of valves and actuators or electrical heating systems. Because of the simple HCW 80 analogue user interface with absolute set point temperature scale, the room set point temperature can be easily adjusted. Follow the installation diagrams to install and connect the power supply to the relay module HC60NG. [. . . ] Do not install the devices over metallic wall connecting sockets and at least 30 cm away from the cover of the heat generator. The room unit HCW 80 can send a test signal to the assigned relay module HC60NG in order to test the signal strength. Keep the teach-in button of the HCW 80 pressed for at least 15 sec until the red LED of the HCW 80 is OFF. When the RF communication is lost for a period of 1 h, the red LED of the relay module HC60NG is ON to indicate that no RF messages have been received during the last hour. When RF communication is re-established the relay module HC60NG will automatically return to normal operation mode. The teach-in operation is required if the relay module HC60NG and the room unit HCW 80 are not pre-bound e. the resetting was successful when the red LED flashes rapidly (1/9 ON/OFF). After the factory reset the HC60NG looses the communication with the HCW 80. After the power up of the relay module HC60NG the red LED will start to flash at 0. If this is not the case set the HC60NG into the reset mode see section 7 "Factory reset of relay module HC60NG". The room set point temperature can be set easily at the set point adjuster by means of an adjustment dial. The room set point range is from 10 °C to 30 °C including the frost protection setting (5 °C). The HCW 80 simulates a mechanical thermostat by LED indication as follows: The red LED at the HCW 80 will be switched ON for 4 sec if the deviation between the set point and the room temperature is >1 °C. Place the two small pins into the holes of the adjustment dial in order to limit the adjustment range (see Fig. 16, the pins are inserted so that the adjustment dial can only be adjusted in the range of 19 °C to frost protection (lower limit) and 19 °C to 30 °C (higher limit) around the value 19 °C. If appropriate, put the adjustment back in, rotated by 180° until it has the position shown.
