Boilerless Control/Electric Heat

(Option)
This option targets building designs that do not
incorporate a boiler to heat the loop system. During a
heavy heating load, the loop temperature may begin to
fall. As the loop temperature decreases, the heating
capacity of the heat pump will also decrease. In the
heating mode, when the loop temperature falls below
55°F (factory setting), the electric heater is energized,
and the compressor is locked out. The system's electric
heat source will continue to be utilized for primary
heating until the loop temperature rises above 60°F.
Once the loop temperature rises above 60°F, the
boilerless controller returns the unit to normal
compressor heating operation and locks out the electric
heater.
For the EXV and DXV models, the electric heat can be
factory installed or field installed by the contractor.
For the EXH and DXH models, the internal electric heat
must be factory installed, the external electric heat
must be field installed by the contractor.
N N o o t t e e : : Note: The boilerless controller has a field
adjustable entering water temperature setting of
25, 35, 45, 55, and 60 degrees. The compressor
operation will return to normal operation when
the loop temperature rises 5 degrees above the
setpoint.
