00 Address
If you are using Communications Mode 0 or 1, and you are installing more than one thermostat, each must be
set to a consecutive address, starting at 1. The default address setting is 1.
An address from 1- 127 may be selected.
01 Communications
mode
The thermostat can communicate with remote systems in 4 different modes. These modes are:
0
300 baud, RS-232 mode (for use with personal computers)
1
100 baud, System mode (OmniLT, Omni, Omni II, OmniPro, and OmniPro II systems)
8
PESM mode, (use with Model 1503 automation systems)
24
Day/Night mode (for use with remote setback switch)
The default setting is 1.

* Energy Efficient Control (EEC) of Auxiliary Heat: Select 0, 1, 4, and 5 to enable EEC, or 8, 9, 12, and 13 to
disable EEC display. See Owner's Manual for description of EEC.
The default setting is 1.
In most heat pump installations, the auxiliary heat is electric resistance heat and the Energy Efficient Control
(EEC) should be turned on (settings 0, 1, 4, and 5). If the heat pump is equipped with a more efficient auxiliary
heat, such as hot water supplied by a gas water heater, you may want to turn EEC off (settings 8, 9, 12, and 13).
The thermostat will act like a conventional 2 stage thermostat.
