White Rodgers 1F95W-80 Check Thermostat Operation, Troubleshooting, Additional Operation Notes

NOTE ADDITIONAL OPERATION NOTES

The battery maintains the stored program in the event of a power failure. When attached to the wall with 24 VAC power applied, the thermostat will function normally with- out the battery. However, the program will be lost in the event of power interruption or failure if the battery is not installed. When power is restored, the thermostat will automatically maintain a temperature of 64°F or a cooling temperature of 82°F (factory preprogrammed) as needed.

Damper operation is linked to the occupied and unoccu- pied temperature settings, rather than the time settings. The default settings for the damper are:

•The damper is open (energized) for the occupied program.

•The damper is closed (de-energized) for the unoccu- pied program.

HEATING SYSTEM

1. Press SYSTEM until HEAT is displayed (it may already

be displayed).

2.Press to adjust thermostat to 99°F. All stages of the heating system should begin to operate within five minutes.

COOLING SYSTEM

!CAUTION

To prevent compressor and/or property damage, if power to the compressor has been off or inter- rupted for more than 1 hour and the outdoor temperature is below 50°F, DO NOT operate the system for at least the amount of time the com- pressor was off! This will allow the compressor heaters to warm the compressor oils to avoid damage due to slugging.

1. Press	SYSTEM	until COOL is displayed.
	HEAT - OFF - COOL - AUTO

2.Press to adjust the thermostat to 40°F. All stages of the cooling system should come on within five minutes (if the compressor is not operating, it may be locked out. See LOCKOUT BYPASS OPTION).

LOCKOUT BYPASS OPTION

!CAUTION

FOR QUALIFIED SERVICE TECHNI- CIANS’ USE ONLY. OPERATORS SHOULD NOT USE THIS FEATURE DUE TO POSSIBILITY OF EQUIPMENT OR PROPERTY DAMAGE, OR PERSONAL INJURY.

DO NOT USE THE LOCKOUT BYPASS OPTION UNLESS THE COMPRESSOR OIL HEATERS HAVE BEEN OPERATIONAL FOR 6 HOURS AND THE SYSTEM HAS NOT BEEN OPERATIONAL FOR AT LEAST 5 MINUTES.

COMPRESSOR SHORT TERM

CYCLE PROTECTION

This thermostat has a built-in short term (5-minute) time delay. During this 5-minute period, the thermo- stat will lock out the compressor to allow head pres- sure to stabilize. If you want to override this feature

while testing thermostat operation, simply press TEMPVIEW

and PRGMVIEW buttons at the same time at initial startup.
