GTS outdoor enclosure sequence of operation

• Power is applied to the outdoor enclosure.

• If the ambient temperature in the enclosure is below

50 °F (10 °C), the strip heaters are powered up. If the enclosure

temperature reaches 35 °F (2 °C), power is allowed to the GTS

subpanel and the GTS unit is enabled. The strip heaters remain

on until the enclosure reaches 50 °F (10 °C) to ensure that

the temperature inside the enclosure does not drop below the

freezing point.

• When the enclosure temperature is at or above 50 °F (10 °C), the

GTS tank heats the enclosure. When there is no call for humidity,

an aquastat maintains tank temperature at the factory default

of 70 °F (21 °C). This temperature can be reset in the field to be

from 40-180 °F (4-82 °C).

• When the ambient temperature in the enclosure reaches 85 °F

(29 °C), two ventilation fans turn on to cool the electronic

components. A high limit is also provided to power down the

GTS if the enclosure temperature reaches 150 °F (66 °C). In a

high limit situation, the ventilation fans continue to run and once

the enclosure temperature falls below 130 °F (54 °C), the GTS

automatically resumes normal operation.

• A normally open drain valve is provided on the GTS outdoor

enclosure to drain the tank in the event of a power loss.
