Issue Operation of multiple Satchwell CZU Fan Coil Unit Controllers from a common Temperature Sensor. Environment Fan Coil Unit installations comprising multiple Satchwell CZU Fan Coil Unit Controllers. Stand alone discreet Satchwell CZU Mk 1, Mk2, Mk3 and Mk4 Zonemaster Controllers CZU1201 CZU1202 CZU1203 CZU2201 CZU2202 CZU2203 CZU3201 CZU3202 CZU3203 CZU4201 Cause From time to time the need arises for office partition layouts within a building to be revised in order to reflect changes in occupancy requirements. This can result in the combination of numerous individual controlled spaces into a common controlled space. This in turn may result in the need to revise associated Fan Coil Unit control systems installed in the controlled spaces affected. Such revisions may require multiple Fan Coil Unit control systems to be controlled from a common Temperature Sensor installed in the common controlled space. This form of control may be achieved by adopting the installation method described in the Resolution. Should the common controlled space be of such a size as to benefit from the installation of averaging Temperature Sensors then this may be achieved by installing 4 non-adjustable Temperature Sensors.  The 4 non-adjustable Temperature Sensors should be wired in a series-parallel configuration in order to ensure compatibility with the associated Satchwell CZU Fan Coil Unit Controller. The series-parallel wiring configuration may be achieved by adopting the installation method described in the Resolution. Resolution 1.  Operation of multiple Satchwell CZU Fan Coil Unit Controllers from a common Temperature Sensor.  Multiple Satchwell CZU Fan Coil Unit Controllers should not be connected directly to a common Temperature Sensor. Instead the common Temperature Sensor should be connected to a single Satchwell CZU Fan Coil Unit Controller. The single Satchwell CZU Fan Coil Unit Controller should then be connected to the associated Fan Coil Unit Heating Coil Control Valve Actuators and / or Cooling Coil Control Valve Actuators. Up to 7 Heating and / or 7 Cooling Control Valve Actuators may be wired to a single Satchwell CZU Fan Coil Unit Controller in accordance with the method shown here 2.  Averaging Temperature Sensor control. Should the controlled space be of such a size as to benefit from the installation of averaging Temperature Sensors then 4 non-adjustable Temperature Sensors may be wired in series-parallel configuration in order to ensure connection compatibility with the associated Satchwell CZU Fan Coil Unit Controller. The 4 non-adjustable Temperature Sensors may be wired in series-parallel configuration to a common Satchwell CZU Fan Coil Unit Controller in accordance with the method shown here

Issue The calectro smoke detektor has too long pipe to fit Environment Calectro Smoke detektor Venturi pipe Cause The Venturi pipe is long, but also possible to cut Resolution You can cut the Venturi pipe to size but you must only cut it from the end that does not have the sleeve. See Installation instruction for more information.  

Issue The documentation on The Exchange differs from the documentation included in the packaging. Neither document shows the full capabilities or wiring options of the transmitter. Environment STO300 Cause The supplier recently changed the PCB and as a result, all of the 300 model plantroom type sensors now offer dual outputs (current and voltage). Since the part number designation is for current only the documentation included in the packaging only shows this configuration. To further complicate matters the specification and installation materials on The Exchange have not been updated to reflect the changes at this time Resolution The installation instructions included in the product packaging should always be referred to when installing these transmitters. The latest installation instructions can be downloaded here. If the new 0-10VDC output feature is required please follow the diagram below for wiring and DIP switch configuration.

Issue The default dynamic port range for TCP/IP has been changed with Windows Vista and later Microsoft operating systems. Product Line Field Devices, Satchwell Sigma Environment Microsoft Windows Vista Microsoft Windows 7 Microsoft Winsow 8/8.1 Microsoft Windows Server 2008 Ethernet communications Microsoft Windows 10 and server 2012, when Sigma is part of an SBO/EBO front end system. Cause To comply with Internet Assigned Numbers Authority (IANA) recommendations, Microsoft has increased the dynamic client port range for outgoing connections in Windows Vista, Windows 7 and in Windows Server 2008. The new default port range starting at port 49152 through to port 65535. This is a change from the earlier Windows configuration that used a default port range of 1025 through to 5000. Sigma used port 49152 as default for communications between Sigma server and Sigma controllers. Resolution You can use SE Legacy Port Reservation to reserve the port used by Sigma. Another resolution would be to redefine the dynamic port range Windows Server 2008 can use to 50000 to 65535, hence keeping the port free for Sigma. (Sigma port requirements can be found in What port numbers are used by the Sigma system?). You can view the dynamic port range on a computer that is running Windows Vista, Windows 7, Windows Server 2008 or 2012 by using the following netsh commands: netsh int ipv4 show dynamicport tcp netsh int ipv4 show dynamicport udp netsh int ipv6 show dynamicport tcp netsh int ipv6 show dynamicport udp Note The range is set separately for each transport and for each version of IP. The port range is now truly a range with a starting point and with an endpoint. Microsoft customers who deploy servers that are running Windows Server 2008 or 2012 may have problems with RPC communication between servers if firewalls are used on the internal network. In these cases, we recommend that you reconfigure the firewalls to allow for traffic between servers in the dynamic port range of 49152 through 65535. This range is in addition to well-known ports that are used by services and by applications. Or, the port range that is used by the servers can be modified on each server. You adjust this range by using the netsh command, as follows: netsh int set dynamic start=number num=range This command sets the dynamic port range for TCP. The start port is number, and the total number of ports is range. The following are sample commands: netsh int ipv4 set dynamicport tcp start=10000 num=1000 netsh int ipv4 set dynamicport udp start=10000 num=1000 netsh int ipv6 set dynamicport tcp start=10000 num=1000 netsh int ipv6 set dynamicport udp start=10000 num=1000 These sample commands set the dynamic port range to start at port 10000 and to end at port 10999 (1000 ports). The minimum range of ports that can be set is 255. The minimum starting port that can be set is 1025. The maximum end port (based on the range being configured) cannot exceed 65535. To duplicate the default behavior of Windows Server 2003, use 1025 as the start port, and then use 3976 as the range for both TCP and UDP. This results in a start port of 1025 and an end port of 5000. Note When you install Microsoft Exchange Server 2007 on a Windows Server 2008-based computer, the default port range is 1025 through 60000.

Issue What NEMA or IP rating is a specific product? Environment All devices Cause Is a product protected against water and access by foreign objects? Resolution The Degrees Of Protection document details both the IP rating and NEMA Enclosure charts. The IP rating is made up of 2 digits, the first is the level of protection to foreign objects, the second is the level of protection to water. If a product does not specify any rating for water ingress in it's datasheet then the the second digit will be 0. The first digit relates to the size of a foreign object that can be inserted into the product. Typically many Buildings products will not allow the insertion of a finger (12.5mm approx' 1/2") and offer no water protection, so they would be rated as IP20, however it would be IP10 should they have holes of up to 50mm (approx' 2").

Issue The discontinuation of the SVT controller due to component obsolescence. Product Line Field Devices Environment SVT Optimiser 4201 4251 Cause What replacements are available for the SVT 4201 / 4251 controllers? Resolution Important Note - The replacement controller mentioned in this article is no longer available, and therefore a replacement for the SVT 4201 / 4251 is not available. The SVT controller range has been discontinued due to component obsolescence. The SVT controller was a basic optimiser that performed the start calculation using only an internal temperature sensor. There are no exact replacements for this controller available. What is available? The Schneider Electric DC1400 Optimiser / Compensator is the recommended replacement, but this is not a direct replacement. Differences in the controllers. The SVT controller provides only an optimum start, the DC1400 provides optimum start and stop. The SVT controller uses only a room temperature sensor for the start calculation, the DC1400 uses only a room temperature sensor and an outside temperature sensor for the start/stop calculations. The SVT controller has a dedicated "Boost" relay, which allows overriding of a CSC compensator, and control valve. This is an internal function with the DC1400 optimiser/compensator. The DC1400 has many other built in functions.   Controller wiring - Modifications will be required. SVT general wiring connections. Relay R1 is the main plant relay and relay R2 is the boost relay. To see the full controller details, please click SVT Optimiser DS2001 0210.pdf DC1400 general wiring details.   To see the full controller details, please click DC1400 DS2044A.pdf Controller Sensors As already indicated, the SVT controller uses only a space temperature detector, and this sensor is NOT suitable to use with the DC1400. The DC1400 controller will, as a minimum, require a room temperature sensor and an outside temperature sensor, meaning that extra wiring for the outside temperature sensor, and the sensor itself, will need to be installed. For details on suitable sensors, please refer to What sensors does the DC1400 optimiser/compensator require?

Issue Replacement actuator for the STL-SR valve Product Line Field Devices Environment STL-SR Cause Replacement actuator for a STL-SR valve Resolution A M800 actuator or MV15B-24 or MV15B-230 actuator can be used to replace the actuator on the STL-SR valve series. Click here for the STL-SR datasheet. Notes: The original actuator e.g. M5CP, may have had a potentiometer fitted to provide position feedback to the controller. There is no direct replacement, the controller, actuator and valve may have to be changed. As a workaround, The M800 provides a 2-10V feedback, using a signal conditioner this could be converted to a resistive feedback. The original actuator may have had end switches fitted, order end switches to suit the replacement actuator. The M800 when used in floating control mode (dip switch 2= On) requires 4 wires. The original actuator used 3 wires to provide floating control.

Issue SER8000 series room controllers communications options Environment SER8000 series room controllers Cause Integration to SER8000 room controllers via Modbus is required.  Resolution Currently, the SER8000 series room controllers communications options are Zigbee Pro or BACnet MS/ TP . Refer to the SER8300 datasheet.  To communicate on Modbus RS-485, an option would be to use the multi purpose manager ( MPM-UN ) as a gateway device.    * Updated July 2015 As per Product Annoucement PA-00428, the SE8000 with firmware 1.3 can now act as a Modbus slave using the RS-485 port.
