• Release
The "Release" setting determines the time program according to which cooling is released.
– 24 h/day (Not recommended): Regardless of the time programs, the temperature of the do-
mestic hot water is continuously maintained at the DHW nominal setpoint temperature.
Example:
– Heating circuit time programs (Not recommended): Depending on the heating circuit time
programs, the DHW setpoint is changed between the DHW temperature nominal setpoint and
the DHW temperature reduced setpoint. The first switch-on point of each phase is advanced by
one hour each time.
Example:
– Time program 4/DHW (Recommended): Time program 4 of the local controller is taken into
account for the DHW mode. The changeover between DHW nominal setpoint and DHW re-
duced setpoint occurs on the changeover times of this program. Thus, domestic hot water
charging takes place independently from the heating circuits.
Example:
– Low-tariff: Released when the low-tariff input is active. (Input EX2)
– Time program 4/DHW or Low-tariff: Released when DHW program is set to "Nominal" or if the
low-tariff input.
