Heat/Cool Decision for the CCP

The central control panel scans all zones continuously (once every 10 to 20

seconds) and determines the quantity and the strength of all heating and cooling

calls. At power-up and on transition from unoccupied to occupied, the greater

number of heat or cool calls determines the mode of the CCP and the airconditioning

system. If the votes are tied, the system defaults to heat.
