30.0
If T2 is over set Outdoor temperature limit for deactivation of time
control for 15 minutes, or if Outdoor temperature limit for
deactivation of time control is set to Off, the additional heat will be
300.0 blocked by time control as long as Additional heat program is
activated.

If T2 is under set Outdoor temperature limit for deactivation of time
600.0
control or if Additional heat program is deactivated the additional heat
will not be blocked by time control.
