Drying Program For Fl Oor Screed - Worcester GREENSTORE Instruction Manual

Drying program for fl oor screed
When the heat pump has been installed in a newly built house with under-
fl oor heating, the Drying for fl oor screed function can be used.
The function is designed to slowly heat up the fl oor for a set number of
days. The temperature is then maintained for a set number of days, fi nally
allowing the fl oor to cool slowly for a set number of days. The heat pump
works during drying operations with the hysteresis set in the display 1.4.
Set how many days you want the heating phase to last.
Set how many days you want the fl oor heating system to maintain the
maximum drying temperature.
Set how many days you want the cooling phase to last.
Set the start and stop temperatures for the drying program.
Set the maximum temperature that the drying program should work at.
The function is activated and deactivated here. Drying program.
Temperature
Due to the continuous operation which
this function requires the electrical
energy usage will be more than in nor-
mal operation. This will be refl ected in
the heat pump running costs during
the drying process.
During drying operations the heat
pump does not produce any hot water
and is not affected by timer controls.
Once the drying program has fi nished
the heat pump returns to normal
mode.
When a second heat curve with mixing
valve is installed, it works according
to the normal heat curve. The mixing
valve must be opened manually when
this circuit is to be included in the dry-
Time
ing program.
