Pulsacoil III - Wall ON/OFF Switches

My Pulsa is wired up to two wall mounted electrical switches. My landlord has told me to switch both switches on to heat electricity at night. One switch has a read light/diode which comes on when activated, the other has no light. I suspect I only need to switch one circuit on for Economy 7. Is it the switch with the light or vice versa ?

He is right.
You need the off peak to heat the unit.
BUT you need the on peak supply to work the unit.
Sensors, PCB and pump etc.

We have both switches on, so am glad to hear thats correct!
