Appendix C: Control Set-up Using PIM
This boiler’s control is equipped with a Program Module (PIM). This device is essentially a special “memory stick” containing a
copy of the software parameters that were programmed into the control by the factory. This PIM has two uses:
1) If the control must be replaced, the data on this PIM may be transferred to a “universal” replacement control, so that
it is correctly programmed with the parameters unique to the boiler at the installation.
2) The PIM provides the service technician with an easy way to return all control adjustments to their original factory
settings.
A. Removal and insertion of PIM
To remove the PIM gently press the tabs at the top and bottom of the PIM and pull straight back (Figure C.1). Replacement con-
trols are not equipped with a PIM and a dust cover is supplied in the PIM slot, which is removed in the same way. If the control is
being replaced, insert the PIM from the old control into the slot on the new control. The PIM may be inserted or removed while
the control is powered.
B. Uploading PIM Data
To upload PIM data use the following procedure:
1) Verify that the PIM is the correct one for this boiler. If the control is being replaced, also verify that the replacement
control is intended for use on this boiler.
2) If not already done, power up the boiler with the new control in place and wait for the appearance of the home screen
(Figure C.2)
3) Press and hold the RH and DWN button for approximately 3 seconds until “RES” screen shown in Figure C.3
appears).
4) Press the RH button to confirm that you want to upload the PIM data onto the control. Note: if you reach this screen
by mistake, you can escape without uploading the PIM by cycling power to the boiler.
5) “RES” will flash during the uploading process. If the uploading process is successful “RES” will stop flashing after a
few seconds. Pressing LH (“Done”) at this point, will return to the Home Screen.
6) If there is a problem, an Error code will appear on the screen. The meaning of these codes is shown in Table C.4.
Pressing the LH (Done”) button will return the user to the home screen without any uploading having been done.
Pressing “Next” will return the user to the RES screen for another attempt.
WARNING
Asphyxiation Hazard. Do not attempt to use this PIM on boiler models for which it is not intended.
All PIMs show the size of the Shadow boiler for which they are intended on the front label. If this
label is missing or unreadable, do not use the PIM. Unauthorized use of PIMs may cause property
damage, personal injury or loss of life.
