Electrical Connection of Anti-frozen electric heater (Reserved)
Electrical Connection of External Heat Source
Using the appropriate cable, and connect the control terminal of heat source such as gas boiler
etc., the control terminal of this unit is 25-26 terminals in the connector base.
NOTE:
This control terminal of the indoor unit only outputs one switch signal; it needs to change wiring
when matching with different external heat sources.
The signal wire connected the solar energy pump with hydraulic module need to be increased
protection, such as fuse, for avoiding the abnormal operation lead to the device damage.
1. If the external heat source need some switch signal to control the
input situation, then directly connect the corresponding wire terminal
of this machine with the corresponding terminals of the external heat
source.
2. If the external heat source needs one control signal of the
specified voltage (such as 220-240V~ 50Hz), then it need to
supply the control terminal25 and 26 with corresponding
power.
External Wiring of Operation/ Fault
●
The terminal 27 and 28 will be conducted when the unit is running, and will be
disconnected when the unit is turned off or stood by.
●
The terminal 29 and 30 will be conducted when there is a running fault, and be disconnected
when the unit is running correctly.
●
The connection is described in the following figure.
Remote ON/OFF Terminal
