MANUAL CONTROLS
A manual switch can be installed in the power supply circuit to the solar storage
tank. The on/off booster switch can be installed with a single element model
connected to either a continuous or an Off-Peak electricity supply, or with a twin
element model to control the bottom heating unit connected to an Off-Peak
electricity supply. The “One Shot Control” switch should only be installed with a
single element model connected to a continuous electricity supply. Discuss the
power supply and manual switching arrangements with the householder.
