Night Setback Temperatures
What are the ideal nightsetback temperatures?
It depends on the type of zone. Generally 52/88 are the best setpoints to use.
This means that during night setback, the heat setpoint becomes 52 degrees, and the cool setpoint
becomes 88 degrees. These are not random numbers. The cost of recovering a zone to its occupied temperature setpoints is NOT a linear function in terms of cost per degree of recovery.
i.e. it costs more to heat or cool a zone 1 degree that is further away from setpoint, than it costs to heat or cool a zone 1 degree that is closer to its setpoint.
The cost of recovery curve begins to increase sharply at 52 degrees for heating, and at 88 degrees for cooling.
"Cost" in this sense is the amount of energy required, in BTU's.
More BTU's then costs more money.
