REGISTER NOTES
a. Outside Temperature: writing to the outside temperature register will cause the thermostat to
display the outside temperature every 4 seconds. The thermostat will stop displaying the outside
temperature if this register is not refreshed at least every 5 minutes.
b. Registers with an upper and lower byte: These registers combine to make a 16 bit number (0-
65025). The 10,000 decimal place is the decimal precision. For example: Register 182 is 0x87
and register 183 is 0x07, which makes 0x8707 or 34567 in decimal. This combined value will be
evaluated as 4.567.
DATA FORMATS
a. Registers: All registers are 1 byte long.
b.
Temperatures: "Omni" format: Temperatures are 1 byte, 0 to 255. 0 is -40 degrees Celsius and -40
degrees Fahrenheit. 255 is 87.5 degrees Celsius, 189 degrees Fahrenheit. Each increment is .5
degrees Celsius. A table is presented in appendix A relating temperature bytes to degrees C and F.
In Fahrenheit mode, the thermostat rounds the display to the nearest whole degree. (71.6 and 72.5
will be displayed as 72.) In Celsius mode, half degree increments are displayed.
c. Programming register time: Time in 15 minute increments. 0 is 0:00 hours, 1 is 0:15, 2 is 0:30,…
95 is 23:45. 96 = blank display, thermostat treats this as having no time for this period (period not
in use)
OTHER COMMUNICATIONS MODES
Day/Night Mode:
The thermostat input is a 12V signal to select preprogrammed night setpoints, no 12V signal to select
preprogrammed day setpoints. This mode is intended for operation with occupied/unoccupied switches or control
systems. Serial protocol is not used in day/night mode.
