When enter ‘Room heat’ mode, user could control compressor and electrical heater through
regulate heat curve or DM (degree minute).
under a certain ambient temperature ,the time start of compressor is determined by degree
minute(DM).
Now we are giving two situations to explain.
1. ‘start quickly’ is determined by FEED(heat curve)
Suppose now the feed water temperature is 25
ć
; regulate the heat curve to let the setting of water
temperature to be a higher value such as 55
ć
,that is FEED25(55). At that time, DM (degree
minute) decrease -30 per minute, when the DM reach -60, compressor will start right away.
(
Notice:
if the water temperature setting is lower than feed water temperature DM would turn
to positive number, and then compressor does not start. Of course, you also can regulate the DM to be
near the value for compressor start, such as -20.
turn it up
2. ‘start slowly’ is determined by FEED(heat curve)
Suppose now the feed water temperature is 25
ć
,if regulate the heat curve to let the setting of water
temperature to be a lower value such as 30
ć
, that is FEED25(30); at that time, the DM would decrease -
10 per minute, the time to reach -60 is becoming longer, only after some time, then
start, such as (-100).
curve is a little flat
When enter room heat mode, it needs customer to regulate the heat curve or DM (degree minute)
according to own request.
compressor can start.
You also can regulate the DM to be more far away from the value for compressor
If you wish to change the ROOM value:
1 Press the ”up” or ”down” button once to open the ROOM value for adjustment.
2 Increase or reduce the preset value using the ”up” or ”down” button so that the desired room temperature is
reached. Wait for 10 seconds or press the left-hand button once to return to the main menu.
