INFORMATION
When the DHW tank mode is reheat, the risk for capacity shortage and comfort
problem is significant. In case of frequent reheat operation, space heating function is
regularly interrupted.
In scheduled mode ( ), the DHW tank produces hot water corresponding to a
schedule. The best time to allow the tank to produce hot water is at night, because
the space heating demand is lower.
