unprecedented flexibility to meet year--round comfort
conditions.
The Humidi--MiZer adaptive dehumidification system has
the industry’s only dual dehumidification mode setting.
The Humi di--MiZer system includes two new m odes of
operation.
The WeatherMaker 50TC--04--07 ooftop coupled wit h the
Humidi --MiZer system is capable of operating in normal
design cooling mode, subcooling mode, and hot gas reheat
mode. Normal design c ooling mode is when the unit will
operate under its normal sequence of operation by cycling
compressors to maintain comfort conditions.
Subcooling mode will operate to satisfy part load type
conditions when the space requires combined sensible and
a higher proportion of latent load control . Hot Gas Reheat
mode will operate when outdoor temperatures diminish
and the need for latent capacity is required for sole
humidity control. Hot Ga s Reheat mode will provide
neutral air for maximum dehumidification operation.
Motormaster Head Pressure Controller
The Motormaster motor controller is a low ambient, head
pressure controller kit that is designed to maintain the
unit’s condenser head pressure duri ng periods of low
ambient cooling operation. This device should be used as
an alternative to economizer free cooling not when
economizer usage is either not appropriate or desired. The
Motormaster will either cycle the outdoor--fan motors or
operate them at reduced speed to maintain the unit
operat ion, depending on the model.
Winter Start Kit
The winter start kit by Carrier extends the low ambient
limit of your rooftop to 25_F(--4_C). The kit bypasses the
low pressure switch, preventing nuisance tripping of the
low pressure switch. Other low ambient precautions may
still be prudent.
Alternate Motors and Drives
Some appli cati ons need l arger horsepower motors, some
need more airflow, and some need both. Regardless of t he
case, your Carrier expert has a factory installe d
combination t o meet your application. A wide selection of
motors and pulleys (drives) are ava ilable, factory
installed, to handle nearly any application.
Thru--the--Base Connections
Thru--the--base connections, available as either an
accessory or as a factory option, are necessary to ensure
proper connection and sea l when rout ing wire and piping
through the rooftop’s basepan and curb. These couplings
eliminate roof penetration and should be considered for
gas lines, main power lines, as well as control power.
Electric Heaters
Carrier offers a full --line of field--installed accessory
heaters. The heaters are very easy to use, install and are
all pre--engineered and certified.
