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
Phase 2: maintain peak temperature
Phase 3: gradual temperature decrease from the peak temperature to 45°C
t_DRYUP sets the duration of Phase 1.
t_HIGHPEAK sets the duration of Phase 2.
t_DRYDOWN 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 3-7.40.
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.
