Adjustment of the MIN and MAX value
Adjustment
of
the
HIGH T STOP and LOW T STOP
value
The MIN and MAX value is the lowest respectively highest value that is allowed for the supply line
temperature. Adjusting the minimum and maximum supply line temperature is particularly important if
your home has floor heating. If your house has floor heating and parquet floor, the supply line
temperature should not be higher than 45°C. Else the floor might get damaged. If you have floor coils
and stone tiles, the MIN value should be 22-25°C in summer when no heating is required to obtain a
comfortable floor temperature.
MIN is the minimum setting of feed water temperature; it is adjustable by operator from10 to 30 ć,
factory setting is 22ć; if the room’s floor use ceramic tile, then the setting of MIN can not less than
22ć (this value can get a comfortable floor temperature); the heat pump will restart as soon as
actual feed water temperature less than MIN setting.
MAX is the maximum setting of feed water temperature, it is adjustable by operator from 30 to 70ć,
and factory setting is 70ć; if heat pump is using for floor heating, this setting is very important,
because at the time the feed water temperature can not higher than 70ć, otherwise could be
dangerous; the heat pump will stop as soon as actual feed water temperature more than MAX
setting.
