Bryant ZONE PERFECT TWO-ZONE - TIMEGUARD AND CYCLE PROTECTION; EQUIPMENT PROTECTION FEATURES

TIMEGUARD
The Zone Perfect Two-Zone provides equipment protection with

initial power up. There is also a 5-minute timeguard delay for all
cooling (Y1) and heat pump modes. The time guard can be cleared
by using the comprotec override feature. Second-stage (Y2) and
(W2) will have a 5-minute delay between stages and also can be
cleared using the comprotec override feature.
