Frequently Asked Questions.
Filter:
Q: Why is there a filter?
A: In Hybrid and Heat Pump (only) the unit moves air through the
system. The filter protects the unit from dirt. A clean air filter improves
efficiency.
Q: How to clean the filter?
A: Leave power on and remove filter from top of unit. Filter can be
vacuumed clean or rinsed with warm water. A dirty filter will reduce
water heater efficiency!
Modes:
Q: What is Heat Pump (Only)?
A: Heat Pump (Only) is the most-efficient mode. It takes heat from
the air to heat water, thereby cooling the surrounding air. Slower
recovery but most-efficient mode.
Q: What is Hybrid?
A: The Hybrid mode combines benefits of Heat Pump (Only) with the speed
and power of Standard Electric. This provides great performance with
less energy.
Q: What is Vacation mode?
A: If you are gone for an extended period, this mode lowers the water
temperature to reduce energy used. Unit will switch to the previous
mode one day before you get back.
Q: What is Electric (Only) ?
A: Electric (Only) mode uses only the resistance heaters to heat the water.
This gives faster hot water recovery than Hybrid mode, but uses more
energy. This mode operates without the fan, stopping the cool air
normally discharged during heat pump operation.
Q: Why does the Electric (Only) green LED flash?
A: In this mode the green LED light will flash after 48 hours as an
indication that the unit is not operating in the most energy efficient
mode.
Operation:
Q: Why can I hear the unit run?
A: In the most energy-efficient models, Heat Pump (Only) and Hybrid, the
method used to heat the water used a fan that can be heard while
running.
Q: The heat pump is not running its normal length of time. What causes
this?
A: Under some conditions, the Water Heater will operate using the
electric elements instead of the heat pump to protect your unit and
ensure hot water is available to you. These conditions include extreme
cold ambient temperature (<35°F), extreme hot ambient temperatures
(>120°F), or very low voltage conditions. The unit will return to normal
operation when conditions permit.
Q: Why does the water heater display a number other than the
temperature setpoint at startup or following a power loss?
A: During commissioning, a self-test countdown number will be displayed
indicating the time remaining before the unit begins normal operation.
Q: Why isn't the temperature setting always displayed on the control?
A: The control will only display the temperature setting when a heat
source is called for by the system and will turn off when the heating
elements and heat pump are not running.
