■ Setting up address using DIP switch
The controller can be used to set the unit's capacity, address and slave unit number. The capacity DIP has
been set at delivery time and cannot be changed. The address DIP and slave number DIP need to be set as
needed after the unit is installed. Customers need to take down the address number and location of the unit
and keep the record in good condition for maintenance reference.
1. The master unit must set the quantity of slave units connected, The slave unit doesn't need to set (bits
1~4 of SW2):
2. Address setting (SW3 and SW4: When SW1.1 is set as master unit, the setting is for master address,
range is 0~99. When SW1.1 is set as slave unit, the setting is for slave address, range is 0~14).
3. Other settings.
SW1.1 ON: master unit, OFF: slave unit
SW1.3 ON: function of auto re-start after power on, OFF: no function of auto re-start after power on.
SW1.4 ON: remote start/stop, OFF: no remote start/stop.
SW1.5 ON: with water system auxiliary heating, OFF: without water system auxiliary heating.
Note:
Address numbers must be unique in the same system.
The unit can only be powered on and commissioned after the address numbers are configured.
The inner side of the control box cover of the unit is attached with an electrical wiring diagram of the unit,
which provides detailed description for DIP settings. Please keep it properly.
