10.3.2 Holiday – recooling
Attempts to reduce, or even to avoid, the system standstill (stagnation)
times at high temperatures. To do this, at night the storage tank is dis-
charged as far as possible to the set minimum temperature, if the stor-
age tank temperature during the day was 20 F below the set maximum
temperature.
Stagnation occurs when not enough hot water is removed from the
system during an absence (holiday).
Notes
The following applies to this function:
• Only activate if you intend to be absent for an extended period.
• Deactivate this after returning from a holiday in order to avoid an
unnecessary waste of energy via the collector circuit.
• This function cannot be activated in systems with swimming pools.
• This function cannot be active at the same time as the drainback
function.
