Solene systems are designed to accommodate three separate modes of operation. Your solar
water heating system can (1) provide 100% solar operation during good weather, or (2) serve as
a pre-heater to your electric water heater adding solar energy when and as available, or (3) 100 %
on utility power during inclement weather.

Turn off the circuit breaker to your solar storage tank. If a water heater time switch has been
installed, set the switch to the “off” position. If you have a mechanical timer remove the trippers
from the face of the switch.

REHEAT
Leave the circuit breaker to your solar storage tank on and set the tank thermostat to the lowest
acceptable temperature setting. The electric resistance heating elements will come on only when
the tank temperature falls below the thermostatic set point. If the solar heated water entering the
tank is warmer than the thermostatic set point, the electric heating elements will not come on. If
you have a water heater timer, you may preset the timer to turn the heating element on and off at
specified times throughout the day if desired.

Leave the circuit breaker to your solar storage tank on and close the isolation ball valves in the
collector loop. In this mode of operation you must turn off the circulation pump. To turn the
pump off, open the controller and change the operational setting from automatic to off. Failure
to turn off the pump can quickly damage the pump motor, shaft, bearings or impeller.
