Compressor Lock Out Time
The lockout feature ensures that the compressor is de-energized for a period of time. The timer varies
randomly from 180 to 240 seconds.
The compressor lockout is initiated every time the compressor is "off" due to:
1. Satisfying the thermostat temperature set point
2. Changing mode to fan only or heat
3. Turning the GE Vertical Zoneline off
4. Power is restored after failure
5. Line power is restored from a brown out condition
Cooling Fan Delay
This is only for the thermostat Fan Auto Mode only.
When the GE Vertical Zoneline cycles cooling ON - starts the fan 5 seconds EARLY.
When the GE Vertical Zoneline cycles cooling OFF - DELAYS the fan off for 30 seconds.
Heating Fan Delay
This is only for Fan Auto Mode (fan cycles with cool/heat operations) and not for continuous fan mode.
When the GE Vertical Zoneline cycles Heating ON - starts the fan 5 second EARLY.
When the GE Vertical Zoneline cycles Heating OFF - DELAYS the fan off for 15 seconds.
Continuous fan operation enables the fan to run continuously.
Fan Speed Change Delay
Relay activation is delayed by a minimum number of seconds. The default for this value is 2 seconds
and is used to eliminate relay chatter.
Room Air Sampling Feature
The room air sampling feature maintains a balanced temperature throughout the room by circulating the
air for 90 seconds once every 9 minutes that the GE Vertical Zoneline is not running when it is set to
cooling or heating mode. By circulating that air, the GE Vertical Zoneline can detect a hot or cold area
in the room and operate the GE Vertical Zoneline to cool or warm the room as necessary. This function
is only available when the fan mode is set to 'AUTO' during COOL or HEAT mode.
