Friedrich R410A manual Compressor Lock Out Time, Cooling Fan Delay, Heating Fan Delay

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 T-stat temperature set point

(2)Changing mode to fan only or heat

(3)Turning the unit off

(4)Power is restored after failure

(5)Line power is restored from a brown out condition

Cooling Fan Delay

This is only for t-stat Fan 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

Heating Fan Delay

This is only for Fan Auto Mode (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.

Continuous fan operation enables 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.

RoomAirSamplingFeature

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 unit is not running when it is set to cooling or heating mode. By circulating the air, the unit can detect hot or cold areas in the room and operate the unit to cool or warm the room as neces- sary. This function is only available when the fan mode is set to ‘AUTO’ during COOL or HEAT Mode.
