For Units manufactured from January 2023 ignores timers with the same start and end time, that is 00:00 on thru 00:00 off will not activate as 12:00 on thru 12:00 off will also not activate. On and off times should have differing minutes also to ensure the desired period is achieved. For example for a full daytime timer a start of 10:00 on thru 16:00 should have the minute increased to 16:01 to confirm the timer window operation.
For Units manufactured prior to January 2023 do not set the second timer to 00:00 ON and 00:00 OFF as the unit will commence heating at midnight every second night. To leave the second time off simply allow the timer 2 setting to timeout after setting the first timer end time.
