UPS
An alternative UPS (Uninterrupted Power Supply), or maintained, supply can be incorporated into an installation
if required by connecting the IEC panel plug on the case. When the mains supply fails this will provide power to the
controls and the pump/solenoid output but the fluid heater control is disabled. A “
MAINS FAIL
” message also
alternates with the normal status in the display. A UPS alarm can be enabled in Parameter Adjustment Level 2 so
that a “
NO UPS
” message alternates with the normal status in the display if the UPS supply is not present. If the UPS
supply fails the unit operates normally when a mains supply is available.

ENGINEER ACCESS PIN
Access to parameter setting Levels 1 & 2 is controlled using an Engineer PIN. The default is set to 1993 but it can be

underline on the first digit.
Press

Press ! to move to the second digit.
•
Repeat the above until the 4th digit is correctly displayed.

Once a correct Engineer PIN has been entered it is enabled for 10 minutes although the display will time-out after 10
seconds of inactivity. However, if the
!
key is pressed within 10 minutes the display returns to the Access Code input
display and Parameter Adjustment Level 1 will be immediately displayed when re-entering the programming function
by a second press of the
