Issue Checking operation of CSC. Product Line Field Devices Environment CSC5252 CSC5352 Cause The operation of the CSC compensator explanation. Resolution The operation of a compensator is to adjust the system flow temperature, in relation to changes in the outside air temperature. The system flow temperature can be further adjusted by the addition of a room temperature sensor, which will provide room influence. The CSC 5252/5352 controller is programmed with a complete set of "Default" settings, these settings will allow the controller to operate as soon as its powered up. Although the controller has a complete range of adjustable settings, accessed through the "Fine Tune Mode", for a basic installation the "Quick Set Mode" can be used. The screen shot below explains how to enter the Quick Set Mode and the settings available. Controller data sheet Controller User guide   Compensated Flow Temperature Set-point: The compensated flow temperature set-point is automatically adjusted based on a ratio for set-point adjustments against the outside temperature changes. A consistent ratio across the entire outside temperature range, may not provide suitable control. For example: with radiator type systems, radiators are less efficient at lower water flow temperatures and need to be provided with a higher temperature to compensate for this initially. The “Set compensator ratio 1”and the “Set Ratio 2” settings provide the ratio of the change to the flow temperature set-point for changes in the outside air temperature, the ratio used is based on the “Set Change-over Value”, with the compensated slope starting from the “Set Flow Origin”. The “Set Flow Temperature Set-up Value” and “Set Night Set Back Value” provide a constant adjustment of the flow temperature set-point to a given building control requirement. The default settings would give a resultant flow temperature as shown follows:     The CSC5352 Calculator presents these settings in a graphical and listed format, making it easier to visually confirm the effects any changes to these settings would make.    

Issue SpaceLogic SLA CO2 units prior to date code 2138 cannot be field calibrated and ABC (Auto Baseline Calibration) is not set to ON by default.

  Issue What is the purpose of modbus registers 35 and 36 in the TC900. Product Line Field Devices Environment TC900 Cause Further detail required for registers 35 and 36 and how they interact.   Resolution The TC900 allows either the onboard sensor or an external sensor or a value e.g. a temperature value binded to a modbus (16bit unsigned) value be written to the TC900 and be used.   Register 24 determines if the in-built sensor (00) or the external sensor (01) is displayed on the screen If register 35 = 00, then the sensor set in register 24 is displayed.   Register 36 has the ability to be the binded sensor and be written to (FC06) with a value x10. e.g 23.5 should be writte as 235. If register 35 = 01, then the value in register 36 is displayed on the screen.   However, if register 23 = 01, then the setpoint is displayed on the screen.   Note, in the TC900, registers start at 0000, therefore in EBO add '1'.

Issue SE7300 and SE8000 room controller fan speeds do not turn off when fan mode is set to auto. When cooling and / or heating is no longer needed, the fan speed remains at low speed. Product Line EcoStruxure Building Expert, Field Devices Environment SE7000 series room controller SE8000 series room controller Cause It is required that the fan be turned off when no demand for cooling or heating is needed. Resolution SE7300 controllers Enter the configuration mode of the room controller. Refer to page 19 of the SE7300 Series Installation Guide for the procedure to enter the configuration mode. In configuration mode, there is a parameter 'AutoFan'. The default mode for this parameter is 'AS'. In order for the fan to stop when there is no demand, the mode should be set to 'AS AD'. AS (Default) = Auto Speed during occupied periods. Fan is always on during occupied periods. Low, medium and high speeds operate on temperature offset from set point. AS AD = Auto Speed / Auto Demand during occupied periods. - Medium and high speeds operate on temperature offset from set point. Low speed operates on demand and will shut down when no demand is present. SE8000 controllers On the room controller, select the fan mode parameter from the home screen. The fan mode must be set to Smart in order for the fan output to function as expected. In Smart mode the fan will turn off when there is no demand for cooling or heating. For SmartStruxure applications of the SE8000 controller This issue can also be seen when binding to the "Value field of the Occupancy Command of the SE8000 controller. Make sure to bind to a priority, not to Value otherwise the fan command will not turn off.

Issue Satchwell ZKM series Rotary Actuator requires replacement due to obsolescence. Environment Satchwell ZKM Rotary Actuator installed on Satchwell MBF series Rotary Shoe Valve Body. Satchwell ZKM Rotary Actuator installed on Satchwell MZF series Plug and Seat Valve Body. Cause Obsolescence of Satchwell ZKM series Rotary Actuator Resolution OVERVIEW The Satchwell ZKM Actuator was compatible with both Satchwell MBF series Flanged Rotary Shoe Valve Bodies and Satchwell MZF series Flanged Plug and Seat Valve Bodies, subject to the installation of an appropriate Linkage Kit. Various models of the ZKM Actuator were available, each differing in the number and type of electrical interface provided, enabling the Actuator to be installed in a range of control applications. Interfaces included Transfer Switches, Auxiliary Switches and Feedback Potentiometers, thus resulting in differing wiring connection options between the ZKM Actuator and its associated Controller and other peripherals. Details of the numerous ZKM Actuator variations available may be viewed here. In view of the differing wiring connection options that may be found on site, it is intended to deal only with the most common 6-wire connection option here. Please therefore check the number of wires connected to the ZKM Actuator before proceeding, as this will assist in confirming the suitability of the ZKM Actuator 6-wire connection option replacement suggestion described here.   1. ACTUATOR REPLACEMENT The Actuator comprising a 6 wire electrical connection enabled it to be operated from a Satchwell Z Monotronic or CZT Climatronic Proportional Controller as follows :- Terminal 1 – Open signal Terminal 2 – Close signal Terminal 3 – Common Terminal A – 135 ohm Feedback Potentiometer – winding Terminal B – 135 ohm Feedback Potentiometer – wiper Terminal C – 135 ohm Feedback Potentiometer – winding If all 6 wires are connected then the ZKM Actuator may be replaced either by the Schneider Electric MD20A Actuator or the M800 Actuator, depending on the type of Valve Body to be controlled :- MBF ROTARY SHOE VALVE BODY APPLICATIONS :- MD20A-24 + Linkage Kit LMD-MBF (914-1070-000) Details of the MD20A Actuator may be viewed here Details of the LMD-MBF Linkage Kit may be viewed here N.B.
