U609 Timer Reset—Defines when the unit changes back to Sleep Mode after having crossed the
high or low temp threshold (Deadband setting on line U611). These values are available:
• NO: The user can use this setting to temporary interrupt a sleep mode interval while sleep
mode is active. If the parameter is left at No, sleep mode will not resume until the next sleep
mode interval occurs or the user sets the parameter back to Yes or Auto.
• YES: If the unit is brought out of sleep mode by a hi or low temperature event, the unit
continue to operate and will go to Sleep Mode again at the next coming Interval.
• Auto: The unit will automatically return to sleep mode if interrupted by a high- or
low-temperature event. The temperature must be within 50% of the temperature dead band
before the unit will resume sleep mode.
U610 Timer Mode Type—Defines what will happen when sleep mode is active. Two options are
available:
• System Off: the unit remains Off, no fans cooling etc. High- and low-temperature events will
not bring the unit out of sleep mode.
• Deadband: Provides the user with a selectable deadband range to bring a unit out of sleep
mode if the temperature in the space gets too high or low. The deadband is defined on line
U611.This setting also allows the unit to come out of sleep mode if a high- or low-temperature
alarm occurs. Temperature alarm thresholds are (internally) shifted lower / higher by the half
value U611.
U611 Dead Band—Defines when a unit will come out of sleep mode when U610 is set for Dead
Band. This deadband is added to the temperature dead band in Service Menu, Setpoints. Once the
control temperature increases above Temperature Setpoint + (1/2 [Temperature Dead Band]) +
U611, the unit will turn On. The unit will remain operating until the temperature is within 1/2
(Temperature Dead Band).
