24 Hour Mode
l
This mode is usually used when the circulation pump runs continuously.
l
The gas heater will activate when the water temperature falls 2° F (-16.7° C) below the set temperature and
the ambient air temperature is below 60° F (15.6° C).
l
When the set temperature is reached, the gas heater deactivates. The heat pump then maintains the water to
the set temperature. If the water temperature again falls 2° F (-16.7° C) below the set temperature, the gas
backup will reactivate.
d.1 Using Gas Boost
When a gas backup heater is installed, the user has the option of using a gas boost to heat the water quicker.
l
This option is available regardless of the gas heater's configuration mode set by the installer (Scheduled Mode or
24 Hour Mode).
l
When the set temperature is reached, the gas heater will deactivate. The heat pump then continues to maintain the
temperature set point. The gas heater will revert to its normal mode (either 24-hour or scheduled).
PLEASE NOTE -
The "Gas boost" option is available regardless of outside air temperature.
This option, however, will only appear in the user menus when the heat pump is actively
heating the water.
