Issue What Oil can be used for the DWT0001 pocket sensor to prevent problems with condensation? Condensation causes the temperature sensor to corrode. Environment Pocket sensor DWT0001 STP660 Cooling Condensation Cause If a pipe sensor pocket is mounted incorrectly on a cooling system condensation can build up in the pocket and corrode the sensor. Resolution Cooling system sensor pockets should be mounted at an angle to prevent condensation building up in the pocket.  See datasheet for the DWT0001, click here.  For the STP660 click here. The recommended oil to use is either  ‘Fina 'Solco' AC43 or Shell 'Dialo Oil B'.

Issue DC1100 / DC1400 Boiler output does not energize during HWS time schedule ON periods Environment DC1100 / DC1400 Discrete Controller installations. Cause DC1100 / DC1400 HWS time schedule is not Boiler Linked. Resolution Please check the catalog for current equipment Check Hot Water Link Option is set to Boiler Linked by following Controller access procedure :- Override Setting Switch :- select SET position. Display Screen / Navigation Buttons :- select parameters SYSTEMS MENU / ALTER SETTINGS / ENTER PASS No. (0112) HOT WATER / LINK OPTION Check LINK OPTION setting If LINK OPTION is set to INDEPENDENT then amend to BOILER LINKED If LINK OPTION is set to BOILER LINKED then PUMP RUN ON may be active If PUMP RUN ON  is active then Boiler outputs will be disabled until PUMP RUN time expires To amend PUMP RUN ON time :- select parameters SYSTEMS MENU / ALTER SETTINGS / ENTER PASS No. (0112) COMPENSATOR / SET-UP MENU / PUMP RUN-ON Amend Pump Run-On time period to 1 MINUTE and observe BOILER No.1 LED status should change from OFF to ON DC1100 / DC1400 Boiler No. 1 output (Terminal 10) should now be energised.

Issue SVT Optimiser Controller does not enable the controlled space to recover to the required day temperature after an unoccupied period during which the inside air temperature has fallen to 12°C. Environment SVT4201 Optimiser Controller fitted with Analogue Time Switch. SVT4251 Optimiser Controller fitted with Digital Time Switch. Cause SVT Optimiser Controller Time Switch settings do not allow for selected Design Preheat Hours (DPH) Resolution SVT Optimiser Controller Time Switch settings should allow for selected Design Preheat Hours (DPH) SVT Optimiser Controller Time Switch settings should be carried out as follows :- Set Td to "Day" temperature required during occupancy. Set Tn to minimum "Night" temperature required during unoccupied periods. Set DPH to design preheat time. DPH is the maximum time required in order to enable the controlled space to recover to the required day temperature after an unoccupied period during which the inside air temperature has fallen to 12 deg. C. Select the approximate time in whole hours on the rotary switch (1 to 5 hours) Fine trim +/- 1/2 hour on the associated setting potentiometer. Note.  ALL "ON" times must be set earlier than the start of occupancy by the selected pre-heat time (DPH) set at (3) above. Example : DPH = 2 hours Occupancy time = 8.00 a.m. Set Time Switch "ON" time to 6.00 a.m. Setting the Time Switch "ON" time to 6.00 a.m. will enable the SVT Optimiser Controller to switch the plant ON at any time between 6.00 a.m. and 8.00 a.m. depending on the heating loss experienced in the controlled space during the preceding plant OFF period. N.B. The setting method detailed in the example above applies equally to both SVT4201 Analogue Time Switch and SVT4251 Digital Time Switch versions of the SVT Optimiser Controller.

Issue Satchwell "AM" series Rotary Actuator requires replacement Environment Satchwell “AM” series Rotary Actuator installed on Satchwell MJF, MZ, MZF, VJF, VSF, VZ or VZF series Plug and Seat Valve Body.   N.B. Where a Satchwell “AM” series Rotary Actuator is installed on a Satchwell VV Butterfly Valve Body then NO simple Actuator replacement is available. In addition to replacing the AMS Actuator it will also be necessary to replace the VV Butterfly Valve Body. The replacement Actuator is S-E type MF type. Please check the latest catalog for current equipment. The Satchwell VV Butterfly Valve Body should be replaced by a S-E Butterfly Valve Body selected from the VF208W series of Butterfly Valve Bodies. It should be noted however that significant pipe work modifications will also be necessary in order to accommodate any selected VF208W series Butterfly Valve Body due to the differing construction of the VF208W Butterfly Valve Body. Please check the latest catalog for current equipment. Cause Obsolescence of Satchwell AM series Rotary Actuator. Resolution Replace Satchwell AM series Rotary Actuator with MV15B-230 Linear Actuator and Linkage Kit :- AM = MV15B-230 + L7SV (880-0126-000) Linkage Kit. N.B. Should the Satchwell AM series Actuator include a wired Auxiliary Switch then the following Auxiliary Switch Pack S2 (880-0469-000) - two independent 250 volt 10 amp (inductive) 3 amp (resistive) rated SPDT Auxiliary End Point Switches - may be purchased separately permitting local installation.   Please check the latest catalog for current equipment.

Issue The word TEST is displayed on the Liquid Crystal Display screen of a Satchwell Climatronic Controller when first powered up during initial installation preventing it from being commissioned. Environment Satchwell Climatronic CSC5252 CSC5352 CXR5805 CXT5605 CZT5305  Controller Display TEST LCD Screen Cause The cause of the word TEST being displayed on the Liquid Crystal Display screen of a Satchwell Climatronic Controller when first powered up during initial installation and preventing it from being commissioned is normally due to a micro processor programming error occurring during the course of production. Resolution There is no field remedy that can be applied to a Climatronic Controller displaying the word TEST on the Liquid Crystal Display screen that will enable it to be commissioned successfully. The Controller should therefore be returned to the vendor for replacement under the terms and conditions of the warranty applicable at the time of purchase.
