*The integral factor is used in the equipment control algorithm to maintain the space temperature at set point.

A short integral factor period will increase the number of cycles per hour. (A short integral factor period will be more comfortable.) A long integral factor period will lower the number of cycles per hour. (A long integral factor period will be more economical..)
