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 temperature set point
(2) Changing mode to fan only or heat
(3) Turning the unit off
(4) Control is rst plugged in or power is restored after failure
(5) Line power is restored from a brown out condition
Wait ICON (Hour Glass )
The wait icon will be turned on when the compressor is locked out and during demand for cooling or heat pump
compressor operation. The Wait ICON will be turned off when the condition clears.
Cooling Fan Delay
Fan cycle/Auto mode only
When unit cycles cooling ON – starts the fan 5 seconds EARLY. When unit cycles cooling OFF – DELAYS the fan
off for 30 seconds
Note: this fan delay is disabled during Test Mode
Heating Fan Delay
This is only for fan Mode Auto (Fan cycles with cool/heat operation) and not for continuous fan mode. When unit
cycles Heating ON – starts the fan 5 seconds EARLY. When unit cycles Heating OFF – DELAYS the fan off for 15
seconds
Note: the fan delay is disabled during Test Mode
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.
Fan Only System Mode
The fan is turned on and runs at the specied manually set speed.
Only the Fan is turned on. Cool or Heat operation are off.
(This is different than FAN MODE CONTINUOUS where the fan is on with the cool or heat operation).
Fan Only Rules
1. If the SYSTEM FAN ONLY MODE is selected, the Auto fan mode is disabled, and the fan mode is forced to
continuous. In addition, the auto fan speed is disabled. If the user presses the fan speed key, the menu will skip over
the auto selection. The set point temperature display is off.
2. Any fan speed may be manually selected during Fan Only Mode.
