Setting the Timer
The
Apollo GEM
timer can be programmed to give 3 on/off times per day for Monday to Friday and 3
different on/off times for Saturday & Sunday.
When the timer is on, the water will be heated at full power regardless of whether any surplus PV power
is available. This allows water to be heated during off peak electricity times or in the early morning before
any PV power is generated.
Each timer on time can switch either output 1 or output 2.
The timer on and off times are programmed in set-up mode using set-up screen 2 for Monday to Friday
times and screen 3 for Saturday and Sunday times.
The timer programming screen is shown below.
To make a pair unused, program the start time to 00:00
NOTE: It is not possible for output 1 and output 2 to be on at the same time.
It is not possible to program times which span midnight, i.e. start one day and end the next. Use 2
time lots if operation across midnight is required.
The 3 ON/OFF times should not overlap. If overlapping times are programmed the timer will turn on at the
first start time and the output and remain on until the off time of the second, overlapped time.
