Issue Temperature Sensor Location Valve Location Actuator Location Product Line Field Devices Environment Actuator Sensor Valve Cause Where to fit and locate field devices. Resolution Valves: If the valve is lift and lay type and the application is diverting, then the valve must be fitted in the return. If the valve is lift and lay type and the application is mixing, then the valve must be fitted in the flow. The rule of thumb for lift and lay valves is "2 ins and 1 out" Rotary (shoe) valves can be fitted in either the flow or return for either mixing or diverting applications. Use pipe unions, so that the valve can easily be removed. Actuators on Valves: If the heating medium is steam then the actuator/valve arrangement is not fitted vertically, tilt the valve/actuator to an angle so that heat can convect away vertically and the actuator is not subjected to as much heat. In all cases, do not fit the actuator/valve arrangement so that the actuator is vertically under the valve. If the valve leaks, it will damage the actuator. Temperature Sensor location, in both wet and air applications the sensor need to sense correctly the medium it is in. Where possible install in a location for easier maintenance e.g. at a height reachable from a fixed floor level. Pipe Temperature Sensors: The tip of the sensor needs to be in the core of the medium i.e. the centre. The sensor needs to be fitted where stratification does not take place or is reduced. This can be achieved by fitting after a pump or after a bend where turbulence provides a good mix. If the sensor is fitted on a bend, then the probe faces the flow of/oncoming water. In CHW applications, fit the pocket just off horizontal, so that any condensation forming in the pocket can drain away. Adequate insulation will prevent condensation forming in the pocket. If fitting vertically in the top of the pipe is unavoidable see Oil for the DWT0001 (or STP660) pocket sensor to prevent problems with condensation. Duct Temperature Sensor: Supply Air - If a probe type sensor is fitted, it needs to be ideally 3 meters downstream and in the centre of the duct from the supply fan and preferably after a bend fitted with turning vanes. Return Air - The temperature sensor needs to be fitted before/upstream of the extract fan. Frost Coils - Temperature sensor, due to the short distance available, probe sensors are difficult to locate, but try to be as far away from the coil e.g. on the other side of the pre-filter bank and in the centre of the duct/AHU. Even better is to use an averaging type temperature sensor. Frost Coils - Fan Hold Off thermostat. Allow sufficient capillary to cover the battery surface. Lace the capillary across the frost battery on the downstream side using the correct clips. If the thermostat body needs to be fitted on the external side of the AHU, then fit with the minimum of capillary on the external of the AHU. Use a grommet or stuffing gland to protect the capillary as it goes through the AHU skin. If the AHU is fitted outside or is in an unheated space then the thermostat needs to fitted internal to the AHU. Do not cut the capillary if it is too long. Tidy capillary ends so they do not flap in the airstream. Outside Temperature Sensor: Outside temperature sensors should be located correctly to the local region you are in and the application they are serving i.e. compensated outside sensor in the UK are fitted on a wall facing north. The sensor should not be fitted on flues, chimneys, near opening windows. They should not be fitted near to compounds containing plant expelling heat e.g. chiller compounds. The sensor should be fitted at a height that does not require the use of steps or ladders for maintenance. Room Temperature Sensor: Sensors should be fitted at an agreed height and not fitted on external walls, near opening windows and doors or above radiators. They need to be exposed to the area they are controlling and not be directly influenced by heat sources e.g. computers. Sensors with exposed setpoint adjust or controls need to be fitted at a lower height so that people with disabilities can adjust them. Sensors that are fitted onto partitioned walls or have a conduit need the hole plugging so that there are no draughts. Sensors that are fitted directly to concrete or steel beams should be packed out with a thermal insulating material. Valves and Sensor Wiring: Allow sufficient cable to allow removal of actuator or sensor without having to disconnect the device. See the full Building Controls Group - Control Sensor Installation guide.

Issue What are CZT, CXT, CXR Controllers? Why are CZT, CXT, CXR Controllers used? What is Proportional, Integral Action and Derivative control. Why does a controller deliver different pulse lengths to the valve and not drive it fully open or closed? What is Pb, IA, PID? Environment CZT CXT CXR DC1100 DC1400 Proportional, Integral Action, Derivative, Pb, IA, PID Cause What do these controllers do and what are their applications? What is Proportional, Integral Action and Derivative control. Why does a controller deliver different pulse lengths to the valve and not drive it fully open or closed? What is Pb, IA, PID? Why is a 0-10V Signal used? Why is a 3 point control / Open Closed actuator used? Resolution Proportional Controllers are used in applications where there are long time lags e.g. room control, return air control, storage calorifier (HWS). Where the controlling sensor is a medium to long distance from the heat/cooling source. An example of a proportional controller is the Satchwell CZT. Integral action controllers are used in applications where there are short time lags e.g. supply air control, frost coil control, non-storage calorifiers. Where the controlling sensor is a short distance from the heat/cooling source. An example of a integral controller is the Satchwell CXT or the CXR. The CXR is a controller where the supply air is controlled, but the setpoint is reset by the return air or space temperature, therefore the time lag is short. Other controllers that fall into this category are the DC1100, DC1400 again the controlling sensor (mixed flow temp) is located a short distance from the heat source.  The term proportional band (Pb) is where the valve is moved to a position proportional to the deviation from setpoint. 0-10V modulating actuators are generally used on these controllers. The term integral action (Ia) is where the valve is moved at a rate according to the deviation from setpoint i.e. the valve is given longer pulses the further away from setpoint, shorter pulses as it gets closer. 3 point control/pulsed pair/open-close actuators are generally used on these controllers. Further to proportional controllers, inherent offset (the setpoint is never quite reached) can be an issue. Integral action can be applied to remove this offset. These controllers are primarily proportional, but integral action can be found on them and is applied. Hence the term PI or PI controller. Derivative control is generally only found on BMS controllers and is used occasionally with PI control, hence the term PID. Here the derivative action moves the valve proportionally to the change from setpoint. It is complex and is rarely used. Further detail about CSC controllers can be found here. Further detail about CXT controllers can be found here. Further detail about CXR controllers can be found here. Further detail about CZT controllers can be found here.

Issue The EGWW sensor is obsolete and needs to be replaced. Environment  EGWW: EGWW 120 Cu 5122720000 EGWW 120 St 5122720010 STP100: 5123102010 5123104010 5123106010 5123108010 5123110010 5123112010 5123114010 Cause Obsolete sensor needs to be replaced. Resolution There is no direct replacement, as the old EGWW had 2 sensor elements and was designed to be used with controllers like TA 219WB (Data sheet here). Also, the EGWW was designed to be mounted directly into the pipe work using a well, and not using a pocket as with the STP100. If only one sensor element is required by the application, the STP100 series sensor is recommended. However, please note that the EGWW well was 120mm or 220mm (see data sheet here), while the STP100 sensor probe and pockets are available in 50, 100, 150, 200, 250, 300 and 400 mm lengths. For more information and details on the STP100 and its different configurations, please see data sheet here. If the 2 sensor configuration is required, you will have to install 2 parallel sensors.
