SuperBus® 2000 Energy Saver Module
Installation Instructions
Product Summary
The SuperBus
2000
Energy Saver Module (ESM) provides a
money-saving and convenient way to monitor and control
temperatures. The ESM uses low- and high-temperature
limits to save energy by overriding the existing HVAC ther-
mostat. When the ESM is on, temperature limits determine
when the heat or air-conditioning turns on. When the ESM
is off, the HVAC thermostat controls heat and air-condition-
ing.
For example, if the thermostat is set for 68°F and the ESM
high limit is 80°F, the ESM prevents the air-conditioner
from turning on until the temperature reaches 80°F. The
ESM limits may be set between 40° and 90°F.
A temperature sensor monitors the temperature and reports
a freeze alarm to the panel if the temperature drops below
the set freeze temperature (default = 42°F). A backup freeze
stat provides additional protection by activating the furnace
if the temperature drops to 45°F (±6°F).
Note
Depending on where the ESM is located, additional
freeze sensors may need to be placed throughout the
residence to provide adequate freeze protection.
This device is backward compatible with Concord
™
panels
with software versions 1.0–1.6 and UltraGard
™
panels.

SuperBus
Compatible panels (SuperBus 2000) have the ability to
auto-address module unit numbers. When the panel is pow-
ered up, the panel automatically reads the unique SuperBus
2000 device ID number and assigns a unit number to the
module. This eliminates manually setting DIP switches and
the chance of identical unit number conflicts.
Non-Compatible panels (SuperBus) communicate with
SuperBus 2000 modules but require the module unit num-
ber to first be set manually using DIP switches.
