A word about savings.

• Every building has a different relationship with
  its cooling plant.
• Some waste a lot. Most waste a lot.
• Most have comfort problems.
• Savings on electricity can range from 5-30
• Exquisite Heat will run it more comfortably and
  efficiently for sure.

4
Efficiency

• Reduced standby loss.
• Increased exchange circulation
• Greater circulation reduces air stratification
• Cooler rather than cold air on moderate days
• Reduced ducting temperature change
• Less generation to satisfy comfort needs.
• Reduced frost.

6
How??

• Precise
• BTU extraction
• for BTU gain.

7
Exquisite Heat

• Adjusts cooling supply temperature in response
  to Thermostat demand history.

8
Even BTU distribution

• Moderated temperatures allow for more evenly
  delivered temperature to the space at longer
  cycles of circulation.

9
Temperature vs. Thermostat

• The higher the air delivery temperature the
  longer it will take the thermostat to sense the
  change.

11
Simple Attachment

• Two wire Thermostat parallel connection input.
• Attach thermistor to supply output.
• Connect low voltage control relay in series.
• Attach 24 Vlt Power from existing source.
• Program system variables.
• Revisit until satisfied with installation
  settings.

13
What happened?

• A changed philosophy of HVAC control.
• The new goal is to satisfy an Ideal Thermostat
  Demand ratio.
• As Actual Thermostat Demand changes in relation
  to Ideal Thermostat Demand, the source output is
  adjusted every hour.

14
Assumption 1

• Increased circulation delivers even comfort.

15
Assumption 2.

• The closer the cooling plant temperature is to
  the room temperature requirement, the more fuel
  efficient the system.

16
Thermostat

• The thermostat takes all heat loss and heat gain
  into consideration.
• The customer can adjust thermostat for personal
  comfort.
• Thermostat activity can be used to adjust
  boiler, HVAC output to satisfy the space with
  ideal circulation.
• The thermostat and energy source interact
  intelligently for comfort and efficiency.

17

• For Exquisite Heat the constant is
• IDEAL THERMOSTAT DEMAND RATIO

18
Ideal Demand Ratio

• A preset thermostat On ratio 70
• The circulation rate at which the heat/cooling
  source is providing the precise BTU supply for
  satisfaction and comfort distribution.
• Thermostat On Circulation On

19
Constant

• Ideal Thermostat Demand Ratio gives us a constant
  for comparison and adjustment.

20
Actual Thermostat Demand Ratio

• The actual proportion of time a thermostat
  calls for comfortable temperature in a given
  period of time. (60 minutes)
• ADR

21
Actual Demand Ratio

• Control takes thermostat on/off status reading
  every second.
• 60 samples/minute x 60minutes
• 3600 samples per hour.
• If thermostat is on for 2520 times/3600 samples,
  the actual demand ratio
• 2520/3600 .70 70

22
What information do we need?

• Previous hour adjusted cooling plant cycle on
  time 40 minutes
• Actual Demand Ratio.
• Period of analysis 60 minutes (5-90 min)

23
Temperature change factor

• Ideal demand ratio .70
• Actual demand ratio .75
• ((ADR-IDR) x10) TCF
• ratio difference .75 - .70 .05
• Time Change Factor .05 x 10 .5
• Cycle time .5

24
Temperature Change Increment

• Temp change increment is an arbitrary factor we
  use to determine the degree of response we want
  to make in the adjustment with the temperature
  change factor.
• 1 Minute x .5 .5 Minute
• 2 Minute x .5 1 Minute
• 3 Minute x .5 1.5 Minutes

25
New High Limit Temp calculation

• Current Cycle Time 40 Min
• ((.75 - .70) x 10) .5 x 3 Min 1.5 Min
• 40 Min 1.5Min 41.5 Min
• New Cycle Time (Higher)

26
Cycle Time Settings

• 40 Min 1.5 Min New ON Time (Higher) 41.5
  Min
• Cycle rest time of 10 Min

27
Time change factor
Ideal demand ratio .70 Actual Demand ratio .55

• Time Change factor ((.55 - .70) x10) -1.5
• Time Change increment 3 Minutes
• Current ON Time 40 Minutes
• ((.55 - .70) x 10)) -1.5 x 3 minutes -4.5 min
• 40 Min 4.5 Min New Cycle time
• (Lower) 35.5 Minutes

28
Factory Settings

• Each control comes from the factory set up to
  attach and run.
• Advanced programming is available for those who
  wish to use it.
• No computer knowledge is needed to install the
  control.

29
All Variables are changeable

• Ideal ratio .5-.8
• Incremental change values (1-5 Min)
• Analysis Period times 5-120 min
• Absolute High and Low limits for alarms and
  reset 5, 10, 20min , 30, 60, 90 Min
• Initial start up Time set lt30-90gt min
• Break times 5-60 Minutes or Proportional

31
Minute to Minute Comfort

• Between analysis within the hour, the thermostat
  can increase the call for heat/cool, by running
  more or less than the Ideal Demand ratio of 60
• If warmer the thermostat can run up to 100.
• If chillier the thermostat runs less than 70.
• The thermostat always responds to the call.
• We only use TT information for analysis.

32
Multi Zone Satisfaction

• Most cases are satisfied by attaching analysis
  zone to average zone in system. The rest of the
  zones will float with variable circulation for
  the hour.

33
What has been done

• We have changed the philosophy of HVAC control.
• The new goal is to give enough to satisfy a fixed
  Ideal Thermostat Demand ratio.
• We adjust the output to meet that Ideal demand at
  the thermostat.
• We provide a more comfortable and more efficient
  method of cooling interior space.

34
Shut Down

• In the event of a control shut down
• Power failure
• Computer switches disconnect control relay off
  and returns HVAC to in series factory low voltage
  controls.

35
Alarms

• Normally open or closed alarm relay is activated
  upon shut down, or safety settings.
• Trigger local alarm, communicator, or security
  system.
• Alarm central or direct dialer to owner and/or
  contractor.
• Additional flood, heat, smoke detection.

36
Cash Flow

• Day after day.
• Year after year. It more than pays for itself.

37
Added Comfort

• Free of Charge
• The feature
• customers notice first

38
Unconditional Guarantee

• Exquisite Heat will exchange failed equipment
  for five years. Lease and rental replacement
  will occur for the term of the agreement.
• Equipment will be removed and rental agreement
  cancelled provided Accounts are current. ( Do it
  Right!!! )
• We are here to refine comfort and efficiency.

39
Manufacturers

• Now have the opportunity to develop efficient
  HVAC and deliver system efficiency to the
  comfort recipient.

40
