[. . . ] The HR80s control the temperature in each room individually and they send the current heat demand to the HC60NG boiler controller. CM67Z controller can also be used to control a zone valve (only in zone 1) The concept of individual room control at each radiator allows the system to be applied in any installation, no re-plumbing required. The CM67Z uses reliable RF communication technology in the 868MHz band. [. . . ] The measured values is used by all HR80 is zone1. When built-in sensor is disabled will also display the measured temperature. The selected value is transferred via RF communication to HC60NG and is used as the key boiler control parameter To ensure synchronous operation of the boiler and zone valves (controlled by HC60NG) in the system one of the CM67Z has to be configured as the system timing master sending the sync signal co-ordinating on/off cycling of all HC60NGs. The CM67 allows you to set the fail-safe mode of operation of the heating system if radio communication is lost. By default HC60 boiler controller relay will be switched OFF in case of communication loss. Alternatively you may choose to cycle the boiler at 2 min ON and 8min OFF. Useful when the building is not occupied for long periods of time and there is a high risk of frost damage. Allows sending a special message to control HC60NG operating as zone valve controller. In this way flow in the whole zone can be controlled with just one valve. This type of control can only be used for zone 1 According to factory default operation HR80 controller will close the valve when open window is detected. This parameter allows configuring the HR80 to perform or ignore this function.

It can be used for system with vertical heat distribution as well as for the ones with manifolds. Re-plumbing f the installation is not required.
