Product Summary
The SuperBus 2000 Energy Saver Mod ule (ESM) pr ovides 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 thermostat. 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-conditioning.
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 fur nace
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.
vs.
SuperBus 2000
Compatible panels (SuperBus 2000) have the ability to
auto-address module unit numbers. When the panel is powered 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 number to first be set manually using DIP switches.

Installation Guide l ine s
Use the following guidelines when installing the ESM:
❑ For Concord systems, up to 16 bus devices can be
connected to the panel (alphanumeric touchpad, HIM,
ESM, etc.). UltraGard systems support up to eight bus
devices.
❑ Each bus device must have a different unit number.
❑ Concord systems allow one ESM per partition. For
UltraGard systems, only one ESM can be connected to
a panel.
❑ The ESM maximum current draw is 30 mA.
❑ Do not exceed the panel total power when using panel
power for bus devices a nd hardwired sensors t hat
require panel power (refer to the specific panel Instal-
lation Instructions).
❑ Use 4-conductor, 22-gauge or larger stranded wire
from the ESM to the panel.
❑ Use 22-gauge or larger stranded wire from the ESM to
the thermostat.
❑ Install the ESM on an inside wall next to or as close as
possible to the existing thermostat. This keeps th e temperature difference between the ESM and the thermostat to a minimum.
❑ Programmable thermostats that use a battery to keep
time and other programmed settings may lose time and/
or programmed settings when the ESM is turned on.
This can happen since the ESM relay is interrupting the
thermostat main power, forcing the thermostat to rely
on battery power to save time and programmed settings. As a result, the thermostat battery may need to be
replaced more often depending on how often and how
long the ESM is turned on.
❑ Refer to the specific panel Installation Instructions for
wire length limits.
Installation
Installation consists of mounting the ESM (next to or as
close as possible to the existing thermostat) and wiring it to
the panel and existing HVAC thermostat.
To mount the ESM:
1. Press down on the top center of the cover and pull it
away from the base (see Figure 2). Set the cover aside.

CAUTION
You must be free of all sta tic electricity when han dli ng
electronic components. Touch a grounded bare metal
surface before touching the circuit board.
2. Place the ESM on the wall at the desired location and
mark the upper-left and lower mounting holes (see Figure 3).
