SuperBus 2000 Energy Saver Module Installation Instructions
Product Summary
The SuperBus 2000 Energy Saver Module (ESM) monitors and
controls temperatures. By overriding an existing HVAC
thermostat, the ESM uses low- and high-temperature limits to
save on energy use. With the ESM on, temperature limits
determine when heating or air conditioning units are on. When
the ESM is off, the HVAC thermostat controls heating and air
conditioning units.
For example, if the HVAC thermostat is set at 68°F and the
ESM high limit is set to 80°F, the ESM prevents the air
conditioner from turning on until the temperature reaches 80°F.
ESM limits can be set from 40°F to 90°F.
If temperatures drop below a set freeze temperature (default =
42°F), a temperature sensor monitors and reports a freeze
alarm to the panel. If the temperature drops to 45°F (± 6°F), a
backup freeze thermostat provides additional protection by
activating the furnace.
Note: Depending on the location of the ESM, additional freeze
sensors may be required to provide adequate freeze
protection.
This device is compatible with Concord
panels.
SuperBus 2000 vs. SuperBus
SuperBus 2000 panels auto-address module unit numbers.
When the panel is powered, a unique device ID number (pre-
programmed at factory) is automatically learned by the panel.
Potential identical unit number conflicts and the need to
manually set DIP switches are eliminated.
Older SuperBus panels can communicate with the ESM by
manually setting the module's DIP switches.

Installation Guidelines
When installing the ESM, consider the following guidelines:
•
For Concord and Concord Express (v4) systems, connect
up to 16 bus devices to the panel (alphanumeric touchpad,
HIM, ESM). For UltraGard systems, connect up to eight
bus devices to the panel.
•
Assign each bus device a different unit number.
•
For Concord systems, use one ESM for each partition; for
UltraGard systems, the panel can accommodate one
ESM.
•
Maximum current draw for the ESM is 30 mA.
•
When using panel power to supply bus or hardwired
devices, do not exceed the panel's total power output.
Refer to specific panel Installation Instructions for further
detail.
•
Use four-conductor, 22-gauge or larger diameter stranded
wire to connect the ESM to the panel.
•
Use two-conductor, 22-gauge or larger diameter stranded
wire to connect the ESM to the thermostat.
•
Install the ESM on an inside wall next to or as close as
possible to the existing thermostat. This helps maintain a
minimal temperature difference between the ESM and the
thermostat.
•
When the ESM is turned on, programmable thermostats
that use batteries may lose their programmed settings.
Because the ESM relay can interrupt the thermostat's
main power, the thermostat may rely on battery power to
