9.3.8 Entering the Maximum Program Runtime
The maximum program runtime is the time that a program-controlled load requires for its longest
program. The maximum program runtime defines the latest time at which a load must be switched on
so that its longest program can be completed within the specified time limits.
Requirement:
☐ The connected load must be program-controlled (see Section 9.3.5, page 68).
Procedure:
• Enter the maximum program runtime for the connected load in the text field Max. Program
Operating Time (see the load manual).
9.3.9 Entering the Minimum Switch-On Time
The minimum switch-on time is the minimum time that the connected load must remain switched on,
for example, to complete its starting sequence or perform a work sequence.
Requirement:
☐ The connected load must be program-controlled (see Section 9.3.5, page 68).
Procedure:
• Enter the minimum switch-on time in the Minimum Switch-on Time text field. Take into
consideration any possible delays in starting the connected load.
Example: Maximum program runtime for a washing machine
You have defined a time slot from 10:00 a.m. to 6:00 p.m. for your washing machine
(see Section 9.3.16 "Configuring the Time Period", page 74), i.e. your washing machine's washing
cycle must be completed by 6:00 p.m.
The longest washing cycle of your washing machine lasts three hours. Therefore, you enter at least
3 hours as the maximum program runtime when configuring the SMA radio-controlled socket.
In this case, the washing machine will start at 3:00 p.m. at the latest so that the longest washing
cycle can be completed. If the selected washing cycle is of shorter duration, the
Sunny Home Manager still adheres to the maximum program runtime.
Delayed activation for some loads possible
Some loads may not start to operate immediately after switching on the SMA radio-controlled
socket, e.g. heat pumps for water storage tanks. Immediate activation can only be ensured for
the SMA radio-controlled socket, but not for the connected loads.
