PulsaCoil A Class Pactrol Micro 7+ controls alongside Immersion Heater Timeswitch

As much as I feel somewhat stupid asking this question, regardless, I don't know the answer, so maybe it's not so stupid!!
I have a PulsaCoil A Class Thermal Storage System which until recently has been working fine. When we last went away, I switched the whole lot off and upon returning, reset the timer controls on the Pactrol Micro 7+ unit. So far so good. However, there is also a Timeguard 7 Day Electronic Immersion Heater Timeswitch which was set when installed so I never had any input with it. Since returning, it has stayed off! Does it need to be on and, if so, what times should I set it for? The same as the Pactrol Micro 7+ or different times. I have absolutely no idea and have tried to work it out reading various PDF's and websites, but it seems the more I read, the more grey matter appears in my head. Please help!

You need instructions for setting the time clocks etc.
Also make sure power is all on.
Off peak supply 7 hours (E7)
On peak as and when required.
If the PC A class has no power then the pump etc will not work.
Always leave the power on when going away as every so often the unit run the pump to prevent sticking.
You need to study the unit book.
And all the clock instructions too.
You will get there. In time.
