If a field-supplied night thermostat is installed in the con
ditioned space, indoor air fan runs only on a call for heating
or cooling. Dampers open only on a call for cooling. On a
call for cooling, economizer cooling is used first and then
integrated with mechanical cooling to meet the cooling
requirement.
A 5-hour, manual bypass timer is provided in remote
control box. This timer, when manually set by building
occupant, will override the UNOCCUPIED mode and place
unit in OCCUPIED mode for up to 5 hours.
Static pressure regulator — When supply air static pres
sure exceeds or drops below pressure regulator setting,
regulator completes an electrical circuit to a damper
motor. The damper motor moves damper to a position that
maintains required static air pressure in the system.

Electrical protection
Compressor
circuit breakers, calibrated for specific
applications, are current sensitive and temperature com
pensated to shut off compressor if current draw is exces
sive. Provide single-phase protection. Reset manually.
Inherent compressor thermal protection, with auto
matic reset, de-energizes the control circuit if extreme com
pressor motor temperature should occur due to excessive
suction gas temperature or motor overloading.
Low-pressure switch automatically shuts off compressor
if refrigerant pressure drops below setting; provides loss
of charge protection.
Inherent outdoor fan motor protection with auto
matic reset — Power circuit opens if motor temperature
becomes excessive.
Indoor fan motor circuit breakers — These manually
reset circuit breakers protect against fan motor overload.
