Domestic Water Heater, Desuperheater
Energy Star promotes the desuperheater and it is offered as an optional item for
all TTHERM GEO™ heat pumps. Our exclusive GEO Logic™ control system
optimizes the operation of a desuperheater, operating the systems only when
there is adequate energy available to provide heat to the domestic hot water.
However, to maximize the times the desuperheater aides in providing domestic
hot water, a hot water preheat tank is suggested.
Note
 The GEO Logic control board has various required setup adjustments, see Field Setup section.
 TTHERM GEO heat pumps leave the factory setup to operate on an open loop. See Open Loop
Solenoid section.
