Confi guration Bits
Address 40001 contains confi guration bits sent from the BAS to the unit. Th ese bits tell the unit to use its own internal inputs,
or inputs from the BAS. When a bit is set to 1, the unit will ignore the corresponding value contained internally, and expect the
BAS to write that value into the Holding Registers. Th e confi guration bits are as follows:
Bit 0 (LSB): Enable
Bit 1: Tank Th ermostat
Bit 2: Rate Command / 10 - 10V Input / Setpoint Command
