Issue When replacing a EM5C BB actuator with a TAC Forta, the EM5C BB may have had  220V running through the switches to control pumps or similar.  Environment TAC Forta with S2 option Cause Using the S2 option to control 220V power supply. Resolution The S2 option is in no way designed to handle 220V, and we do NOT recommend this.

Issue There is a difference between the STD300 sensor flanges compared to the ones pictured in the data sheets. Environment STD300 Cause Design differences between picture on data sheet and actual sensor. Resolution There was a slight design change on the sealing flange a while ago where the metal piece was replaced by a plastic flange. This to get a more flexible surface to the duct, and therefore a better seal.

Issue Want to be able to run the SE7200 in floor heating and chilled beam simultaneously. Environment SE7200 Cause running simultaneous applications. Resolution Unfortunately the SE7200 will only handle 1 main application per controller due to its limited I/O.

Resolution VWG-APP-1045:  option card  that fits directly into a Tridium JACE controller to provide communications between controllers and the gateway device. VWG-EPP-1045: option card that fits directly into the American IA range of controllers with an RS232 interface

Issue Please define the difference between the V211 and V211T Environment V211 V211T Cause There are 2 different valves with similar characteristics, what differences are there, and why should I choose one or the other? Resolution V211 is equipped with flanged connections, while the V211T has internal threaded connections.

Issue Needs a 230V actuator to replace existing actuator on customer installation Environment V211T Venta MV15B Cause Since most actuators are 24V, the 230V option is not too common. Resolution The 230V version of MV15B, part no 880-0460-000 is suitable as actuator for the V211T.

Issue Which actuator is suitable to replace the Forta M750 actuator? Environment Forta M750 Forta M800 Cause Since the Forta M750 is no longer available, it needs to be replaced by a suitable actuator. Resolution The Forta M750 should be replaced by the Forta M800 actuator.

Issue The data sheet states 2 different power consumptions: Power consumption: average 6 VA Transformer sizing: 30 VA Which one should be used for calculating power supply? Environment Forta Cause There are different figures specified in the documentation for the Forta series actuator. Resolution Average consumption is 6VA, but the peak consumption is 30VA, and this is just before the valve reaches the fully closed position.

Issue The Vadsbo plug in transformer series is no longer available through Schneider Electric.  Environment Vadsbo transformer Cause Replacing product that was formerly included in product portfolio. Resolution No replacement product is currently listed. Replacement purchase needs to be done locally.

Issue Needs to replace older actuator on V282 valves that are still working. Environment Forta V282 V294 V384 V386 V394 V298 Cause Replacing old actuators on valves that are still in good working condition. Resolution The Forta series actuators are direct replacements, with the exception of DN15 valves.

Issue Boilers do not operate when HWS output is on. Environment Drayton DC 1100 DC 1400 Boilers not working HWS Hot water Cause "Boiler Linked" has not been selected in the menu setup. Resolution By default the controller does not have the "Boiler Linked" option set. Set the rotary switch to "Set". In the display menu structure choose; "System Menus" "Alter Settings" Enter the pass number of 0112 and press enter. "Hot Water" "Link Option" Choose the "Linked Option". Return the rotary switch back to "Auto"

Issue DO2202 outside air temperature sensor replacement. Environment DO2202 Cause DD2202 sensor has gone faulty, what replaces it? Resolution The sensor is no longer available from Schneider Electric. However they are available from: Sontay, part no.
