, daily multiple time period scheduling - 🧠ANSWER ✔✔The programming of
time-based control functions for atypical periods of building occupancy.
control logic - 🧠ANSWER ✔✔The portion of controller software that
produces the necessary outputs based on the inputs.
seven-day scheduling - 🧠ANSWER ✔✔The programming of time-based
control functions that are unique for each day of the week.
proportional control algorithm - 🧠ANSWER ✔✔A control algorithm in which
the output is in direct response to the amount of offset in the system.
control strategy - 🧠ANSWER ✔✔A method for optimizing the control of
building system equipment.
thermal recovery coefficient - 🧠ANSWER ✔✔The ratio of a temperature
change to the length of time it takes to obtain that change.
control loop - 🧠ANSWER ✔✔The continuous repetition of the control logic
decisions.
optimum start control - 🧠ANSWER ✔✔A supervisory control strategy in
which the HVAC load is turned ON as late as possible to achieve the indoor
environment setpoints by the beginning of building
