selected outside temperature range to ensure bivalent operation of supplementary source and heat
pump. To ensure continuous release of the supplementary source, setting "---" must be selected on
the respective operating lines. If both release values are enabled, the outside temperature must sat-
isfy both criteria, thus ensuring release of the supplementary source.
• Over-temperature protection
Overrun time of release for the external source: If the integral indicates another heat deficit before
the overrun time has elapsed, the release remains activated. If the set overrun time elapses before
the common flow temperature drops below the common flow temperature setpoint, the release is
deactivated also.
