Issue Dimension comparison when replacing MZF valve with VG311 or V321 Environment MZF V321 VG311F Cause Replacing Satchwell MZF valves, the new valve is a different size, i.e. larger. Resolution The Satchwell MZF valve is a physically smaller valve when compared to other manufacturers valves of the same DN. The only solution is to modify the pipework. For the valve datasheets click on the relevant valve type MZF VG311F V321 The table below details the differences.

Issue Satchwell DuoFlow Information Environment DuoFlow DM5601 SA2452 TLX2259 Cause Drawing for a Satchwell DuoFlow System using a DM5601 valve and actuator. Resolution Download here drawing for a Satchwell DuoFlow system. DuoFlow Valve/Actuator cable colours are as follows: White = Central Heating Orange = Hot water Yellow = Mid Position (Central Heating and Hot Water) Blue = Neutral Note 1: The DuoFlow actuator wiring is different to a Mid-Position actuator, therefore conversion from a DuoFlow system is best done by replacing the wiring centre as well, The room and cylinder thermostat can be retained.

Issue Wiring a MD10B-24 / MD20B-24 actuator to a Climatronic CXT / CXR / CSC Actuator Environment MD10B-24 MD20B-24 Actuator Climatronic CXT CXR CSC Cause The Climatronic controller switches the O volt side of the 24 volt supply, but the actuators shows that it requires 24 volts to open and close. Resolution The Satchwell range of Climatronic controllers have always switched the 0 volt side of the 24 volt supply to control the actuator position. CXT Controller - Terminals 13 and 14 provide 0 volts to close or open the actuator. A permanent 24 volts is provided by terminal 37. For the complete datasheet, please click HERE. CXR Controller - Terminals 23 and 24 provide 0 volts to close or open the actuator. A permanent 24 volts is provided by terminal 37. For the complete datasheet, please click HERE. CSC Controller - Terminals 33 and 32 provide 0 volts to close or open the actuator. A permanent 24 volts is provided by terminal 37. For the complete datasheet, please click HERE. The MD10B-24 / MD20B-24 datasheet shows the wiring as follows; For the complete MD10B datasheet, please click HERE. For the complete MD20B datasheet, please click HERE. The above actuator wiring shows a 0 volt connection to the common connection (1) and a switched 24 volt connection (2 or 3). To connect the MD10B-24 / MD20B-24 actuator to any of the above controllers it will be necessary to connect the actuator as follows. Controller 24 volt  (37) to connection wire (1). Controller Open signal (14, 24 and 32) to connection wire (2). Controller Close signal (13, 23 and 33) to connection wire (3). Please note that the actuator direction can be changed by repositioning the switch on the front of the actuator.

Issue What is the replacement for the Drayton Autotherm? Environment Drayton Autotherm Cause The Drayton TA/L1 actuator is obsolete, and no like for like actuators are available, this makes the Autotherm controller unusable. Resolution The TA/L1 actuator provides positional feedback to the Autotherm controller, and actuators providing feedback are very few, and providing the correct feedback is not possible. The Autotherm controller provides considerable functionality, and in our current  ranges of controllers, these cannot be matched. To upload the Autotherm data sheet, please click HERE.     The most appropriate replacement controller is CSC5352. This device will provide a compensated heating system with a timed start, the output relay can be used to enable the hot water system. Please click HERE to upload the data sheet. If separate time periods are required for the heating system and how water system, then the DC1100/1400 should be considered. Please click HERE to upload the data sheet. Please note that in both of the above options, new sensors will be required and possibly actuators too.

Issue What can the Boost relay (R2) be used for? Environment Boost Termination Day control Relay R2 Cause The plant continues to operate even when the temperature is greater than the Td setting. Resolution The SVT Optimiser has a primary function of performing and optimised timed start, this is achieved using a space temperature sensor to provide an indication of the buildings internal temperature The controllers secondary function will allow a "Boost Function" or "Day Control" of the plant. The controller output relay R2 is used for this function. Boost Function. Relay R2 contacts 5 - 4 make at the end of occupancy, ready for boost period. Relay R2 contacts 5 - 3 make at Occupancy start and provides a termination of the Boost period. For Boost Operation set the slide switch to position "A" as shown below.   Day control. Relay R2 contacts 5 - 4 make when the space temperature is above the (Td) setting. Relay R2 contacts 5 - 3 make when the space temperature is below the (Td) setting.

Existing Satchwell Actuator installed on MJF 3-Port Flanged Valve Body may be retained for installation on replacement   S-E 3-Port Flanged Valve Body.  In such instances a S-E L8TV Linkage Kit will additionally be required.  Alternatively an Actuator from the S-E range of Actuators may be installed on the V311 3-Port Flanged Valve Body, in which case no additional Linkage Kit will be required. IMPORTANT NOTE It should also be noted that the face to face dimension of the S-E V311 3-Port Flanged Valve Body differs to that of the Satchwell MJF 3-Port Flanged Valve Body  Similarly, the centre line to bottom of third port dimension of the S-E V311 3-Port Flanged Valve Body differs to that of the Satchwell MJF 3-Port Flanged Valve Body  As a result alterations to the pipework connected to the MJF 3-Port Flanged Valve Body will be required.

Issue Replacing a CSC2701 compensator with a CSC5252. Environment CSC 2701 5252 compensator Cause The CSC2701 compensator has been superseded by the CSC5252. Resolution The conversion is normally fairly straight forward, but can be more complicated if an SVT is used to provide a boost signal. . Please note that the link between terminals 34 and 35 is only fitted where a 24 volt actuator is used. In the chart above the old and the new terminal numbers are shown. If the old controller was connected to an SVT, which provided a boost facility, terminals 1, 4 and 5 were used to achieve this. With the new CSC, this facility is achieved using the "Setup" function. This is achieved by linking SVT terminals 4/5 to 7/8 on the CSC, having first removed the link. To review the CSC2701 data sheet, please click HERE. To review the CSC5252/5352 data sheet, please click HERE. Please be aware: since July 2016 the CSC compensator and other descrete controllers were withdrawn from service.

Issue Drayton DC1000 and DC1100 differences Environment DC1000 DC1100 Cause What are the differences between the DC1000 and the DC1100? Resolution The DC1000 was the predecessor of the DC1100, and therefore their functionality is very similar. From the information below it can be seen that the main difference is that the DC1000 had only one boiler output and had a "System On" output. The DC1100 has two boiler outputs and therefore can sequence the boilers, but it does not have a "System On" output. It should be noted that the Remote Communications module is no longer available.
