Robertshaw Smart Sense Series Installation Manual page 21

The SMART 2000 is fitted with a number of safety and energy saving time delays.
If desired, these can be disabled for commissioning purposes by entering the
Advanced Installer Mode and setting the CD=00 value to read CD=01. After exiting
the Advanced Installer Menu you will note a
LCD to remind you that Commissioning Mode is ON.
IMPORTANT:
After commissioning has been completed, it is important to disable
Commissioning Mode by entering the Advanced Installer Menu
once again and setting the CD = 01 value back to CD = 00.
NOTE:
When in Commissioning Mode, ALL time delays are either OFF or reduced
to an extremely low value. It is therefore normal to potentially call for 3rd
stage heating almost instantly 0.5 degrees below the heating setpoint.
If you choose not to use Commissioning Mode you may see various words and
icons flashing in the LCD whenever a time period is in use. For example, the word
HEAT may flash to indicate heating is required but being held OFF by the four
minute anti-cycle timer. Or the word HEATING may be flashing to indicate the
setpoint has been achieved however heating is being held ON by the minimum
run timer.
For the SMART 2000, anything that flashes is a time period overriding
what would normally be expected to occur. This indicates a function is
being held ON or OFF momentarily. Please be patient.
