If, after installation, the error occurs sporadically, it may be due to unstable communication, due to the Gateway being too far away from the devices or if there is an obstacle between them. To solve the problem, it may be useful to try moving the Gateway to a different position so that the device is closer to the control that is causing the transmission error, or to a position that allows the signal to overcome the obstacle.
Communication between devices and the Gateway takes place via radio waves (868 MHz); it is therefore important that the Gateway is installed in a central area of the home while taking account of the need for a strong internet signal to allow communication with the CALEFFI CODE® app and the “Caleffi Connect” cloud.
The maximum distance depends on the structure and obstacles between the devices. It is advisable to place the Gateway in a central area of the flat (in an area with a good Wi-Fi signal if you will be using this type of connection). The sensors must be wall-mounted, in an area not exposed to heat sources such as direct sunlight, not above the radiators but at least 1 metre away from them, and should not be placed on any shelves covering the radiator.
The CALEFFI CODE® system can be used to control radiator systems that are part of either independent or centralised systems. This includes medium to large-sized systems such as those in Hotels or Bed and Breakfasts as it can manage up to 64 zones simultaneously through a single Gateway. With the CALEFFI CODE® system, radiant panel systems (heating only) can also be managed, both independent and centralised, by connecting the Sensor PRO (ambient temperature sensor with boiler contact) code 215002, 215002 BLK to the Caleffi 656 series 24 V electrothermal controls, regulating the temperature of each zone separately.
During the installation phase, if the error “lost communication with Gateway” appears and persists for 10-15 minutes, it means that there is a communication problem. In this case, you will need to move the Gateway or add a second Gateway. Bear in mind that if you move the Gateway to a better position, you will have to wait a few minutes for the error to disappear.
If one or more Comfort Control electronic controls and a Sensor / Sensor PRO ambient temperature sensor are installed in the same zone, the temperature detected by the ambient temperature sensor overrides that of the electronic control.
Yes, to replace the old thermostat, the Sensor PRO (code 215002/215002 BLK) with the Gateway (code 215100/215100 BLK) or the Gateway PRO (code 215015/215015 BLK) can be used without installing the controls on the radiator. Naturally, without Comfort Controls, you will not have the benefits of modulating regulation, which would ensure greater efficiency and, as a result, greater energy savings.
No, fan coils cannot be managed as it is not possible to manage the various derived speeds of ventilation.
Incorrect ambient temperature detection may be due to non-optimal positioning of the Comfort Control electronic control, code 215510/215510 BLK. If the radiators are recessed in a niche, are totally or partially covered, or if the “Comfort Control” controls are installed on very high radiators or at floor level, it is preferable to install an ambient temperature sensor, code 215001/215001 BLK, to improve temperature detection.
If there are no Sensor / Sensor PRO ambient temperature sensors in the same zone, but if several Comfort Control electronic controls are installed, the temperature in that specific room is detected by averaging all the temperatures recorded by the electronic controls. All “Comfort Control” electronic controls will still independently control the temperature of each radiator.
