The Polaris control unit of the ProAir multi-zone management system provides four different ways of controlling the ducted unit, depending on whether they are direct expansion or hydronic machines:
E0: LACK OF COMMUNICATION BETWEEN POLARIS CONTROL UNIT AND CHRONOTHERMOSTAT. On the control unit, the error is shown by the chronothermostat flashing (T1, T2, etc.) and by the wording 'NO COMMUNICATION'. If radio remote controls are provided, check that the control unit is correctly powered, or that the antenna is screwed in tightly. Another cause could be the distance between the control unit and the chronothermostats. Check that they are not too close (within 1m) or too far (over 25m). Finally, the last problem could be that the chronothermostat that displays the error does not belong to the system or that the Polaris control unit is disconnected.
Instead, in the case of a wired chronothermostat, check that the entry and exit from the control unit with relative polarity of the cables used has been respected according to the user manual.
E1: ABSENCE OF MASTER CHRONOTHERMOSTAT IN THE SYSTEM. Assign the master timer thermostat to the ProAir system. In the case of radio frequency chronothermostats, only the Discovery 2X or 3X models can be configured as such, while regarding the Stealth 2X or 3X wired chronothermostats, any zone can be set in this way.
E2: ABSENCE OF ASSOCIATION OF AN ACTUATOR, FANCOIL OR SV WITH A THERMOSTAT. All the chronothermostats present in the system must have at least one actuator, one fancoil or one SV associated. If this error appears, from the control unit check that there are no '?' on the strings of OUT 1 and 2.
E3: ACTUATOR FAULT. Actuator movement error, which is indicated by the red flash of the LED and by the reference symbol 'O' on the control unit. Check the correct insertion of the actuator in the damper body or vent and if necessary remove the plug cable from the IN for a few seconds in order to allow the motor to reset. Once the plug has been re-inserted, the system will automatically perform a functioning test.
E4: NO COMMUNICATION BETWEEN THE ACTUATOR AND THE POLARIS CONTROL UNIT. This type of error, in the control unit, is represented by the flashing of the affected actuator. The error may be due to incorrect wiring of the dampers (polarity not respected), or incorrect insertion in IN or OUT. Also check that the cables used are of a suitable type, in particular those supplied by Tecnosystemi (NO LAN CABLES) and if necessary also check the crimping of the RJ45 connectors. If all the precautions listed above have been respected, check that an actuator not present in the system is not associated with a chronothermostat.
E8: GENERIC ANOMALY. In the event of an anomaly in a zone where there is a slave (especially if the LEM probes are present), this error will appear in the master chronothermostat of the system.
E9 or Lo: TEMPERATURE SENSOR FAULT. This error will appear if the chronothermostat temperature sensor is calibrated or damaged. In this case it is necessary to replace the chronothermostat.
BAT: LOW BATTERY. In the Discovery 3X and Mini Discovery 3X chronothermostat, if the abbreviation BAT appears on the display, it means that the batteries are almost flat and must be replaced. If they are not replaced, the chronothermostat display will switch on and off frequently and will show the letters Id.
Of course, the ProAir system has a completely free application that you can find in the App Store (iOS) or in the Play Store (Android). Its name is ProAir Multi Zone and it will allow you to manage your system from wherever you are, simply using your smartphone.
Yes, in ProAir systems equipped with a Polaris 4X or higher control unit, it is possible to interface with the Google Home and Amazon Alexa voice assistants.
No, the ProAir does not interface with home automation systems. This is because it is already an advanced system in itself, with chronothermostats, control unit, application, etc.
Server Communication Error: this type of error can be displayed on the app side if there is no communication between the Polaris ECU and the server (via Wi-Fi router). In this case, check the correct configuration of the control unit with your home router and above all its coverage.
Error E6: status error, connection is temporarily interrupted. Check that the router is properly powered and that the connection with the Polaris ECU is stable.
Command sending error: momentary error related to the fact that due to external causes the application was unable to reach the server to send the command. Check your connection and if necessary try sending the command again.
The connection must be made in cascade between the control unit and the various chronothermostats, respecting the polarity of the cables (+AB-). Regarding the cable to be used, the shielded 4x0.22 is recommended.
By combining the ProAir system, the relay module available in the catalogue, 2 or 4 wire thermostatic valves can be managed, thus allowing the use of a single chronothermostat to manage both the ducted unit and the radiant system.
The Sirio 2.0 dampers are equipped with one clean input contact and one output contact. The IN contact gives consent to open or close the damper (without partialisation). Instead, in the Sirio 0.10V dampers the input is set up to receive a voltage from 0 to 10V; this allows, by partialising the voltage, managing of the various positions of the butterfly located in the damper.
This distinction is necessary because only in the case of a Master equipment is it possible to integrate a Slave damper/nozzle into the system. The Slave damper/nozzle will then execute the same command given to the Master one.
This type of installation is recommended in cases where it is necessary to have two dampers or nozzles serving the same room. Therefore management will take place from a single command.
Of course. Having a clean contact or a 0.10V contact for management, it is possible to integrate Sirio dampers with home automation systems.
Yes, pack systems with sheet metal or polystyrene plenums (Eolo/Mini Eolo) are available in the catalogue, both for the Sirio 2.0 and the 0.10V dampers.
The Smart Sirio timed chronothermostat is available in the Show Gas catalogue, perfect for managing Sirio 2.0 dampers.
Yes, the power supply is always supplied as standard.
Attention: in the case of Master and Slave devices, only the Masters require the power supply.
