The HWAT-ECO-GF has 7 default timer
programs. Select a program by tapping on the
corresponding box (box will turn red).
Select the installed HWAT heating cable.
Default values are set for selected plumbing set
values. Change the default values by clicking on
the arrow sign for each value and enter a new
value.
Select the type of cable used in your
installation.
Selection range 1/2" (DN 15) up to 5" (DN 100)
if HWAT-R2 is used. Selection range 1/2" (DN15)
up to 2" (DN 50) for HWAT-P1 heating cable.
The ambient temperature is the temperature
inside the room where the heating cable is
installed. Use the +/- keys to select a
temperature from 50°F ( 10°C) to 77°F (25°C).
Clicking on the "back" icon will store the value
and show it in plumbing settings. Range: from
50°F (10°C) to 77°F (25°C).
The maintain temperature is the water
temperature that you set for normal use. The
minimum temperature is 98°F ( 37°C ) or the
economy temperature, whichever is higher.
The maximum temperature depends on cable
type, pipe thickness, insulation thickness and
ambient temperature.
WARNING: Per ASHRAE Guideline 12-2020,
Maintaining hot-water temperatures consistently
above 120°F (49°C) between the water heater
and fixtures has been used successfully as a
Legionella control method.
The economy temperature is the water
temperature for periods in which the amount of
hot water used is low (at night) or high (peak
period).Select the temperature using the +/-
keys. The minimum temperature is 98°F (37°C)
for use in environments such as schools, and
106°F (41°C) in the Apartments program. The
maximum temperature is the selected maintain
temperature.
The test program runs for 30 minutes, during
which all parameters will be ignored to check
heating cable and connection on site. You can
stop the test program at any time.
