The time, in minutes, that must expire to switch between cooling

 

 

2284, 2286,

mode and heating mode. Actual switchover depends on the

 

 

2287

active temperature control loop being below the value of

 

 

 

SWITCH LIMIT (Point 85) and exceeding the value of SWITCH

 

 

 

DBAND (Point 90).
