▪ 1 (2 LWT zones): 2 leaving water
temperature zones. The zone with the
lowest leaving water temperature (in
heating) is called the main leaving
water temperature zone. The zone
with the highest leaving water
temperature (in heating) is called the
additional leaving water temperature
zone. In practice, the main leaving
water temperature zone consists of
the higher load heat emitters and a
mixing station is installed to achieve
the desired leaving water temperature.

# Code Description
[A.2.1.9] [F-0D] When the space heating/cooling control
is OFF by the user interface, the pump is

the pump runs every 5 minutes to
check the water temperature and
demand heating or cooling if
necessary. Remark: Sample is NOT
available in external room thermostat
