of the disconnect or load side as required by code. The
“unpowered”
option is to be powered from a separate 115/120v
power source.
The unpowered convenience outlet is available as a 15 amp
factory-installed option or a 20 amp field-installed accessory.
Non-fused disconnect
This OSHA-compliant, factory-installed, safety switch allows
a service technician to locally secure power to the rooftop.
When selecting a factory-installed non-fused disconnect, note
they are sized for the unit as ordered from the factory. The siz
-
ing of these do not accommodate field-installed items such as
power exhaust devices, etc. If field installing electric heat with
factory-installed non-fused disconnect switch, a single point kit
may or may not be required.
RTU Open, multi-protocol controller
Connect the rooftop to an existing BAS (building automation
system) without needing complicated translators or adapter
modules using the RTU Open controller. The RTU Open con
-
troller speaks the 4 most common building automation system
languages (BACnet, Modbus, Johnson Controls N2, and Lon
-
Works). Use this controller when you have an existing BAS.
Besides the 4 protocols, it also communicates with a Bryant
Open system (i-Vu and VVT
®
).
Condensate overflow switch
This sensor and related controller monitors the condensate
level in the drain pan and shuts down compression operation
when overflow conditions occur. It includes:
• Indicator light – solid red (more than 10 seconds on water
contact – compressors disabled), blinking red (sensor dis
-
connected)
• 10 second delay to break – eliminates nuisance trips from
splashing or waves in pan (sensor needs 10
seconds of con-
stant water contact before tripping)
• Disables the compressor(s) operation when condensate plug
is detected, but still allows fans to run for economizer.
Power exhaust with barometric relief
Superior internal building pressure control. This field-installed
accessory may eliminate the need for costly, external pressure
control fans.
