FLOOR DRYING UP
For newly-installed under-floor heating systems, floor drying up mode can be
used to remove moisture from the floor slab and subfloor to prevent warping or
rupture of the floor during floor heating operation. There are three phases to
the floor drying up operation:
Phase 1: gradual temperature increase from a starting point of 25°C to the
peak temperature. After running a unit of time(t_dryup/9), the set
temperature of a unit of time rises 3
℃
until the peak temperature.
Phase 2: maintain peak temperature 45
℃
Phase 3: gradual temperature decrease from the peak temperature to
30°C. After running a unit of time(t_drydown/7), the set temperature of a
unit of time declines 3
℃
until 30°C.
t_DRYUP
sets the duration of Phase 1.
t_HIGHPEAK
sets the duration of Phase 2.
t_DRYD
is the duration of Phase 3.
T_DRYPEAK
sets the heat pump’s leaving water set temperature for
Phase 2.
START TIME
sets the floor drying up operation start time.
START DATE
sets the floor drying up operation start date.
The heat pump’s leaving water set temperature during the floor drying up operation is illustrated in Figure 3-7.52.
During the floor drying up operation all buttons except
OK
are inactivated. To exit
the floor drying up operation, press
OK
and then select
YES
when prompted.
Note: In the event of a heat pump malfunction, floor drying up mode will continue
if a backup electric heater and/or additional heating source is available and
configured to support space heating mode.

AUTO RESTART
sets whether or not the unit re-applies the user interface settings
when the power returns following a power failure. Select
YES
to enable auto
restart or

If the auto restart function is enabled, when the power returns following a power
failure, the unit re-applies the user interface settings from before the power failure.
If the auto restart function is disabled, when the power returns after a power
failure, the unit won’t auto restart.
