controller returns the unit to normal compressor heating
operation, and locks out the electric heater.
For units comprised of the field installed duct heater
option, the unit will ship from the factory with controls
available to interface with the field provided electric heat
selection.
Note:
For geothermal applications, the boilerless
controller has an adjustable setting of 25, 35, 45, 55,
and 60 degrees.
Supplemental or Boilerless Electric Heat
(Option)
The GEH/V 6 to 25 ton models which contain boilerless
control electric heat or supplemental electric heat will
contain the controls interface ONLY for field provided
electric heat selection. The heater for this model shall be
external to the equipment by the contractor for ease of
installation. All power connections for the electric heater
will be completely separate from the unit for field supplied
electric heat.
Note:
When the unit has boilerless control, the electric
heat is not used as supplemental electric heat, but
as a primary heat.
Hot Gas Reheat (Option)
With the reheat option, the return-air from the space is
conditioned by the air-to-refrigerant coil, then reheated by
the reheat coil to control not only the space temperature,
but to also reduce the relative humidity of the space. When
operating in the reheat mode (meaning the sensible
temperature has been met in the space), the humidistat
signals the reheat relay coil to energize, allowing the high
pressure refrigerant gas to flow from the compressor
through the reheat valve, into the reversing valve and
reheat coil.
A switching relay has been provided for the reheat
application to adjust the blower motor from normal
operation to low speed when the hot gas reheat is
energized (for 0.5 to 5 ton and EXH/V070 equipment only).
Note:
A high static blower motor is required to support
the hot gas reheat option for the GEH/V 0.5 to 5 ton.
Note:
Units containing the hot gas reheat option should
not be used as a make-up air unit.
2-Speed Blower Motor (Option)
The 6 to 25 ton GEH/V models have indoor blowers that are
available with 2 speed motors, selectable in the model
number (Digit 12, drive packages one to nine). High speed
airflow matches the single speed motor airflow,
referenced in the Fan Performance tables. Low fan speed
airflow is approximately 50% of high fan speed airflow.
The 6 to 25 ton GEH/V two-speed blower motors are
available with the following options: Deluxe 24V or UC400
controls, Heat Pump (HP) or HP w/Hot Gas Reheat or HP w/
Waterside Economizer. Not available with Boilerless or
Supplemental Electric Heat.
