!CAUTION

FOR QUALIFIED SERVICE TECHNICIANS’ 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 OP- TION UNLESS THE COMPRESSOR OIL HEATERS HAVE BEEN OPERATIONAL FOR 6 HOURS AND THE SYSTEM HAS NOT BEEN OPERATIONAL FOR AT LEAST 5 MINUTES.

COMPRESSOR LONG TERM CYCLE

PROTECTION

To protect the compressor from potential damage due to temperature change of crankcase oil, this thermostat has a built-in time delay of one hour less

than the power loss to the unit (up to 12 hours maximum lockout). During this time, auxiliary heat will be used when necessary to maintain setpoint temperature. DO NOT attempt to override this delay feature before crankcase temperature has stabi- lized (for example, if power has been out for three hours, the compressor should remain locked out for two hours).

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 pressure to stabilize. If you want to override this feature while testing thermostat operation, simply
