10. How??
Precise
BTU replacement
for BTU loss.
December 28, 2018

11. Energy act 2007
The law now provides that boiler manufacturers for residential hot water heating must provide a means for adjusting out put to actual heat load by 2012.
Exquisite Heat is the ideal solution.
We want you to try the product on your lab or sample home at your location.
Let us send you one to try.

12. Exquisite Heat
Adjusts heating/cooling supply temperature in response to Thermostat demand history.
December 28, 2018

13. Even BTU distribution
Lower heating plant (boiler/furnace) temperatures allow for more evenly delivered temperature to the space.
December 28, 2018

14. Temperature vs. Thermostat
The lower the medium temperature the longer it will take the thermostat to sense the change.
December 28, 2018

15. December 28, 2018

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

23. What happened? A changed philosophy of boiler control.
The new goal is to satisfy an Ideal Thermostat Demand ratio.
As Actual Thermostat Demand changes in relation to Ideal Thermostat Demand, the boiler output is adjusted every hour.
December 28, 2018

24. Efficiency Reduced standby loss. Increased heat exchange circulation
Better convection at baseboard and radiators.
Less back wall radiation loss.
Reduced piping radiation loss.
Less BTU generation to satisfy comfort needs.
December 28, 2018

25. Discussion of how it is done.
December 28, 2018

26. Increased circulation delivers even comfort.
Assumption 1
Increased circulation delivers even comfort.
December 28, 2018

27. Assumption 2.
The closer the heating plant temperature is to the room temperature requirement, the more fuel efficient the system.
December 28, 2018

28. 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 for comfort and efficiency.

32. For Exquisite Heat the constant is
IDEAL THERMOSTAT
DEMAND RATIO IDR

33. Ideal Demand Ratio A preset thermostat On ratio = 70%
The circulation rate at which the heat source is providing the precise BTU supply for satisfaction and comfort distribution.
Thermostat On = Circulation On

34. December 28, 2018

35. December 28, 2018

36. Constant
Ideal Thermostat Demand Ratio gives us a constant for comparison and adjustment.
December 28, 2018

37. Actual Thermostat Demand Ratio
The actual proportion of time a thermostat “calls” for comfortable heat in a given period of time. (60 minutes)
ADR
December 28, 2018

38. 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/ = = 70%
December 28, 2018

39. What information do we need?
Previous hour adjusted High Limit Temperature = 150 degrees F
Actual Demand Ratio
Ideal demand ratio (.70 )
December 28, 2018

40. Temperature change factor +
Ideal demand ratio = .70
Actual demand ratio = .75
((ADR-IDR) x10) = TCF
ratio difference = = +.05
Temperature Change Factor x 10= +.5
Temperature change factor = +.5

41. 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 F x = F
2 F x = +1 F
3 F x = F
December 28, 2018

42. New High Limit Temp calculation
Current High Temp Limit = 150 F
(( ) x 10)= +.5 x 3 F = +1.5F
150 deg F + 1.5F = F
New High Temp Limit (Higher)
December 28, 2018

43. Limit Settings 150 F + 1.5F = New High Temp Limit (Higher) = 151.5 F
Differential of 10 F
High Limit 151.5F
Low limit of F
December 28, 2018

44. Temperature change factor -
Ideal demand ratio = .70
Actual Demand ratio = .55
Temp. Change factor = (( ) x10)= -1.5
Temp Change increment = 3 degrees F
Current High Temp Limit = HT= 150 degrees F
(( ) x 10)) = -1.5 x 3 degrees F = -4.5F
150F – 4.5F = New High Temp Limit
(Lower)=145.5 degrees F

45. Factory Settings
Each control comes from the factory set up to attach and run.
No computer knowledge necessary is needed to install Exquisite Heat control.
Advanced laptop programming is available.
A programming sheet is available to have the factory set up needed settings.
December 28, 2018

46. All Variables are changeable
Ideal ratio
Incremental temp change values: (1-5F)
Sample and cycle times: min
High and Low safety limits for alarms and reset: 100, 120, 130 – 160, 190, 200
Initial start up High Temp set: F-190F
Temperature Differential: degrees
Low limit = High Temp limit – Temp. Differential

47. December 28, 2018

48. 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 70%
If chillier, the thermostat can run up to 100%.
If warmer, the thermostat runs less than 70%.
The thermostat always responds to the call.
We use TT information for analysis.
December 28, 2018

49. December 28, 2018

50. What has been done Changed the philosophy of boiler control.
The new goal is to give heat to satisfy a fixed Ideal Thermostat Demand ratio.
We adjust the boiler output to meet that Ideal demand at the thermostat.
We provide a more comfortable and more efficient method of heating interior space.
December 28, 2018

51. 12/28/2018
A word about savings.
Every building has a different relationship with its heating plant.
Some waste a lot. Most waste a lot.
Most have comfort problems.
Savings on fuels can range from 5-30%
Exquisite Heat will run it more comfortably and efficiently for sure.
December 28, 2018

52. Reduction of chimney waste
Air Pollutants: CO2, NO, etc.
Particulates & heat
December 28, 2018

53. Domestic Hot Water
A Second thermistor is provided to monitor Domestic Hot Water. If the Thermostat does not call for heat for one hour the second thermistor is used to satisfy domestic hot water limit temperatures. ( 120F-150F)
December 28, 2018

54. Multi Zone Satisfaction
Most cases are satisfied by attaching analysis zone to average zone in system. The rest of the zones will float with Thermostat call activity.

60. Shut Down In the event of a control shut down:
Power failure
