Savastat LC - Energy Saving Boiler Controls
Significantly Reduces Unnecessary Boiler Cycling!
Savastat LC works with existing boiler
controls to help reduce the energy used for space heating or process hot
water loop systems by up to 25% or more annually. (WE
GUARANTEE A MINIMUM 15% SAVINGS) Savastat LC is easily installed on existing boilers with a minimum amount of downtime.
(allow about 15 minutes of down-time, and an hour to commission) Applications
for the Savastat LC unit are for low pressure non-modulating HW Loop System boilers only.
Savastat LC units can be adjusted for 24v, 110v, or 220v boiler thermostat operating
How can we ALWAYS GUARANTEE a minimum
15% annual energy savings with Savastat LC on space-heat systems?
Professional Heating &
Plumbing Installer Two Time Winner!
Savastat LC employs an additional level of intelligence to hot
water heat boiler system controls. By monitoring the return water temperature
and rate of temperature decay (return temp. at the boiler) it can
determine the load on the system. This allows for small adjustments to be made
in mean system temperature, that often accumulate to savings in excess of 20%
reduction in fuel consumption and associated costs. Microprocessors have
revolutionized control systems in recent years. The Savastat LC processor samples
the system twice per second, so it is working in 'real time' to compute savings
potentials. It doesn't use historic data to try to 'out think' the system and
predict what might happen. As we all know, weather changes can be dramatic and
short term, often fooling devices that try to predict system demands.
What Savastat LC Will Do:
Reduce energy consumption by 15% or more
or provide an ROI of 24 months or less.
Reduce boiler maintenance costs and
excessive wear on
reducing boiler short-cycling.
Savastat LC works with existing boiler controls such as
compensation controls, optimizers and building management
Install easily with minimal required
Principle of "Load
Savastat LC works under the
Load Compensation. When a boiler (or
boilers) is at maximum demand (early morning start up, for example), Savastat
will take no action because there will be no opportunity to make a saving. At
any other time when a full load condition does not exist (when the space/room
temperature is nearing its set point of 66 - 70 degrees F, for example),
Savastat will make savings by adjusting the boiler operating temperature in
relation to these reduced load conditions. Savastat achieves this savings
by measuring the RATE OF TEMPERATURE LOSS of the return water to the boiler and
applying a level of intelligence to the boiler thermostat to prevent the boiler
from firing wastefully. Status lights on the unit confirm when savings are
being made. This action does not affect comfort levels because Savastat will
never prevent hot water from being delivered to the radiators or other heat
Savastat LC is an appropriate upgrade on all traditional low water temperature
boilers using radiators and heat exchanger space heating, except for those
implementing modulating control systems. Some hot water loop process boiler
systems are compatible as well. Check with your Savastat Representative
for details concerning non space-heat applications, and to determine if Savastat
LC may help your organization lower operating costs.
Savastat LC status lights indicate which mode the device is currently in. If
none of the status lights are illuminated there is no 'call for heat' by the
boiler thermostat, this means the boiler thermostat circuit is open and the
boiler’s burner is off.
IDLE: When the boiler thermostat
initially calls for heat, the yellow idle light is illuminated for a 30 second
delay while Savastat LC computes what action to take next. Savastat is analyzing
the system status in “real time” to determine if heat is needed to be put into
the system, or savings can be achieved by holding the burner off.
SAVE: When only one green save light
is illuminated it indicates that Savastat LC has entered a save mode preventing the
boiler from firing while the computation involved is looking at how fast the
return water temperature is dropping away from the set reference temperature.
BOOST: When both the save light and
the boost light are illuminated Savastat LC has entered a save mode while the
computation involved is looking at how fast the return water temperature is
dropping towards the set reference temperature.
RUN: The red run light will be
illuminated when Savastat LC has finished its active mode and allows the boiler to
fire. When the boiler finishes its burn, this light will go out and the cycle
will repeat the next time the boiler gets a ‘call for heat’, and is asked to
If you are considering upgrading your boiler control systems to modulating
equipment, BE SURE TO CONSIDER THE SAVASTAT LC UNIT FIRST! The cost
differential between the modulating equipment and the Savastat LC is enormous, and the payoff for the LC unit is often
well under 12
Savastat LC eTrac LC Test Port Adapter - an ECMI Exclusive!
All Savastat LC units provided by ECMI come standard with our
EXCLUSIVE test port adapter wired into the Savastat LC connector
leads. This allows simple integration of the eTracLogic
eTrac-LC test device for energy auditing purposes. The eTrac-LC allows us to run a
comprehensive energy analysis on the boiler to determine EXACTLY
what savings are being achieved by the Savastat LC unit at your
facility. See eTracLogic Systems eTrac-LC information pages
for further details about how this device works to show our client
their actual savings. Also contact us about our
Savastat LC Test Drive Program
to see how we work with our clients to show the actual benefits
being achieved with Savastat LC.
Note Concerning Savastat LC & Energy Star:
contacted the DOE Energy Star Program regarding our Savastat LC unit, and the
possibility of inclusion of the unit in the Energy Star Program. Because
Savastat LC does not currently fall within the categories developed by this
program, we are unable to qualify the product at this time.
our Savastat LC controller is considered a sub-component of an overall system,
program approval would require packaging our Savastat LC unit with a specific
boiler system to test and confirm specific energy savings with the overall
system. Progress is being made in this area regarding OEM application of
Savastat LC with various boiler manufacturers. Updates to follow as
If your company is a boiler manufacturer and
would like to look into offering Savastat LC as an OEM option,
