When the heat pump check the temperature on the water box T5U
≥
65
℃
, no matter
whether CN26 get the signal or not, CN2 will never output 230V signal, solar pump can
’
t work. Until
water temperature turn down to T5U
≤
60
℃
, the CN2 will make the solar pump work.
Note: Usando
If we use guide 1, when the solar pump work, the heat pump can also operate normally
.
Guide 2:
.
When the pump station check the temperature is OK in solar pipe, it will output 230V signal, and
the CN26 will get this signal, then the CN2 will output 230V signal to control the contactor, the
contactor will close, the solar pump will turn on. And the CN11 will check the ON/OFF signal; the heat
pump will stop operating.
.
When the pump station check the temperature is not OK, it will stop output 230V signal, CN2
will also stop output 230V signal, the contactor open, solar pump will turn off. And the CN11 check
the ON/OFF signal, the heat pump will operate.
.
When the heat pump check the water temperature on the water box T5U
≥
65
℃
, no matter
whether CN26 get the signal or not, the CN2 will not output 230V signal, solar pump can
’
t work. Until
the water temperature on the water box T5U
≤
60
℃
, the CN2 will make the solar pump work.
Note
:
If we use guide 2, when the solar pump work, the heat pump cannot operate.
