Electronic Control System
Manual Component Activation Mode
Manual Component Activation Mode allows a Service Technician to activate and toggle through various unit func-
tions while observing the corresponding function codes and associated temperatures in the LCD. This mode also
allows for voltage checks at the activated components without having to wait for the zone to call for cooling.
To initiate Manual Component Activation Mode, the unit must first be ON and in Diagnostic Mode
NOTE: If Fault Codes have been logged the control will enter Fault Code Recall Mode instead of Diagnostic Mode.
If this happens press the ALARM key to shift the electronic control system into Diagnostic Mode.
While in Diagnostic Mode, and keeping in mind that the components can be activated in only one zone at a time,
press and hold the desired zone's COLDER key and the POWER key for ten (10) seconds
88), at which time all cooling functions will stop; the letters "OF" and "F" will appear in the LCD, and all icons in the
LCD will illuminate.
The chosen zone's components can now be forced to ON for five (5) minutes, or back to the OFF states using the
WARMER or COLDER keys, with the WARMER key activating the next step (component), while the COLDER key
would activate a previous step (component). (See Manual Component Activation Tables on next page).
NOTE:
• All temperatures displayed are current, real-time temperatures without weighted averaging or offsets.
• Pressing any key (other than the POWER or ALARM) during this mode restarts the five (5) minute timer.
• Pressing the POWER key during this mode forces the control back into Diagnostic Mode.
• Pressing the ALARM key will exit the mode, and return the unit to normal operation.
