●
Water level control: When low water level switch disconnected, open re-water solenoid
valves to rewater, meantime stop supplying water to water pump. Open suppling water pump
after high water level connected, shut off rewater solenoid valves after high water level
connected for 2 minutes(at least 2 minutes for rewater switch open and shut off ).
●
When supplying water pump opens, don't rewater to water tank once it's temp. less than
(setted temp. -5
) during disconneted high water level, rewater once water tank temp. more
than (setted temp. -2
), shut off rewater solenoid valves after high water level conneted for
2 minutes. When supplying water pump stops, do need rewater timely whenever ( at least 2
minutes for rewater switch open and shut off).
●
At the first time to turn on unit, Circulating pump/ compressor/ fan could run after low water
level conncted.
●
When unit operates, Circulating pump opens. When unit shut off, Circulating pump will delay
30 minutes to stop running.
●
When supplying water pump opens, re-water solenoid valves opens at same time, after 10
minutes to detect rewater temp., when rewater temp. is more than ( water tank temp. -5
),
rewater solenoid valves stops. When rewater temp. is less than (water tank temp. -10
),
open rewater solenoid valves again, make supplying water pipe keep hot water for long time.
When suppling water pump shut off, meantime rewater solenoid valves shut off.
●
Four-way valves is on the disconnect status when normal running, only connect to work
during defrosting.
