Example Messages (Data shown in parenthesis are in Hex)
Host: Poll thermostat 1 for Group 1 data:
RA(01), DL/MT(02), CS(03)
Thermostat 1: RA(81), DL/MT(63), low setpoint(xx), high setpoint(xx), mode(xx),
fan(xx), hold(xx), current temperature (xx), CS(xx)
Host: Broadcast time:
RA(00), DL/MT(41), start register(41), seconds(xx), minutes(xx) , hours(xx),
CS(xx)
Thermostat(s): no reply, it was a broadcast message.
The host should wait a minimum of 90ms before transmitting next message.
Host: Set cooling setpoint on thermostat 5
RA(05), DL/MT(21), start register(3B), setpoint(xx), CS(xx)
Thermostat 5: RA(85), MT/DL(00), CS(85) (acknowledge)
Host:
Set the energy custom message to “CUSTOM MESSAGE” on thermostat 1.
RA(01),DL/MT(21), start register(AF) , ‘C’(43), ‘U’(55), ‘S’(53) , ‘T’(54),
‘O’(4F), ‘M’(4D), ‘ ‘(20), ‘M’(4D), ‘E’(45), ‘S’(53), ‘S’(53), ‘A’(41), ‘G’ (47),
‘E’ (45), ETX (03), CS(34)
Thermostat 1: RA(81), MT/DL(00), CS(81) (acknowledge)
