SMA sunny home manager - Minimum Switch-On Time; Minimum Switch-Off Time

Example: Maximum program operating time 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, page87), 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, enter at least
threehours as the maximum program runtime when configuring the 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.
Requirement:
☐ The connected load must be program-controlled (see Section9.3.5, page81).
Procedure:
Enter the maximum program operating time for the load connected in the Max. Program
Operating Time text field (see the load manual).
9.3.9 Entering the Minimum Switch-On Time
The minimum switch-on time is the minimum time that the load connected must remain switched on,
for example, to complete its starting sequence or complete a work sequence.
Requirement:
☐ The connected load must be program-controlled (see Section9.3.5, page81).
Delayed activation for some loads possible
Some loads may not start to operate immediately after switching on the radio-controlled
socket, e.g. heat pumps for water storage tanks. Immediate activation can only be ensured for
the radio-controlled socket, not for the connected loads.
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.
9.3.10 Entering the Minimum Switch-Off Time
The minimum switch-off time is the minimum time the connected load must remain switched off, for
example, to prevent overheating or enable fault-free restarting.
Requirement:
☐ The connected load must be program-controlled (see Section9.3.5, page81).
Procedure:
• Enter the minimum switch-off time in the text field Minimum Switch-off Time.
