Friedrich SS10N10*, SS14N10*, SS12N10*, SS15N30*, SM18N30* service manual Compressor Lock Out Time

Page 28

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 first 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 specified 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.
